Dried glucose (soluble corn fibre) can be found in Health Canadas Health Claim Assessments webpage and in the Canadian Food Inspection Agencys Table of Acceptable Food or Food Constituent Function Claims. Due to the advantages that SSF offers bacterial species have also been used to produce the enzyme under SSF conditions. De Almeida Siqueira, E. M., Mizuta, K., & Giglio, J. R. . Also the control of process parameters like temperature, pH, aeration, oxygen transfer and moisture can be done conveniently [20]. There are various methods by which microorganisms can be manipulated at a genetic level in order to improve and optimize the production of this enzyme. The ubiquitous nature, ease of production and broad spectrum of applications make -Amylase an industrially important enzyme. 251, Sir Frederick Banting Driveway, Tunneys Pasture, A.L. Resistant corn starch or The layer of starch is subjected to hydrolysis in the desizing process where -Amylase is employed to cleave starch particles randomly into water soluble components that can be removed by washing. -Amylase is gaining increased attention due to its starch hydrolyzing properties and the activities that can be carried out owing to this property. Amylose constitutes 20-25% of the starch molecule. Gupta, R., Gigras, P., Mohapatra, H., Goswami, V. K., & Chauhan, B. Microbial -amylases: a biotechnological perspective, rcsb.org (http://rcsb.org/pdb/images/1hny_bio_r_500.jpg?bioNum=1). Building Blocks of Carbohydrates Alpha-amylases are found in plants and in animals. Starch: It is formed by the condensation of amylose and amylopectin. Production of amylase by. Anto, H., Trivedi, U., & Patel, K. -Amylase production by Bacillus cereus MTCC 1305 using solid-state fermentation. Amylose vs Amylopectin This method has several advantages. Amylopectin is the other component that makes up about 70-80% of the starch in plants. Demirkan, E. Production, purification, and characterization of -amylase by Bacillus subtilis and its mutant derivates. Humans and other animals have amylases, so they can digest starches. Sharif, L. Olsson, Production of fungal a-amylase by, Knox, A. M., du Preez, J. C., & Kilian, S. G. Starch fermentation characteristics of, M.S. 2) Microorganisms can be easily manipulated using genetic engineering or other means. Dried glucose corn fibre This is a crucial factor in fermentation process. Most animals cannot digest cellulose. These molecules exhibit different characteristics that determine the digestibility of the starches that contain them. It was discovered by Meyer and his co-workers in 1940 during their studies on maize. The corresponding polysaccharide in animals is called glycogen. it depends on the presence of a metal co factor for its activity [4]. Unlike SmF, in this fermentation technique, the substrates are utilized very slowly and steadily. The most widely used source among the bacterial species is the Bacillus spp. Glucose syrup soluble corn fibre Bacillus subtilis, Bacillus stearothermophilus, Bacillus licheniformis and Bacillus amyloliquefaciens are known to be good producers of thermostable -Amylase. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.Some species of bacteria secrete it to form biofilms. The onus is on the legal agent to comply with Sections 4 and 5 of the Food and Drugs Actand Section 6 of the Safe Food for Canadians Act. Iefuji, H., Chino, M., Kato, M., & Iimura, Y. Raw-starch-digesting and thermostable alpha-amylase from the yeast Cryptococcus sp. Starch is a polysaccharide composed of two types of polymers amylose and amylopectin. Yang, S. S., & Wang, J. Y. Protease and amylase production of Streptomyces rimosus in submerged and solid state cultivations. It is a polymer of alpha- Glucose and consist of two components: Amylose and Amylopectin. This gives a measure of the extent of hydrolysis of starch by -Amylase [2]. The resulting fractions were pooled and further applied to a DEAE-Sepharose ion exchange column [57]. Starches are made up of two kinds of molecule: amylose and amylopectin, which connect together to form starch granules. D, Sivaramakrishnan. A. tamarii actively synthesizes -Amylase when cultured on maltose, starch and glycogen under static conditions. In polymer chemistry, branching is the regular or irregular attachment of side chains to a polymer's backbone chain.It occurs by the replacement of a substituent (e.g. Clostridium thermosulfurogenes yielded maximum enzyme at a pH of 7.0 [56]. There is no regulatory requirement for a Health Canada premarket assessment of novel fibre sources, contrary to the premarket notification required for Novel Foods governed by Division 28 of the Food and Drug Regulations. The aim is to use substrates that are waste or by products of other processes in order to make the process of enzyme production environment friendly. Detailed information on the substantiation of health claims can be found in the Guidance Documents for Preparing Health Claims Submissions. This high glucose syrup can then be converted into high fructose syrup by isomerization catalysed by glucose isomerase. improving laxation or regularity by increasing stool bulk; reducing blood total and/or low-density lipoprotein cholesterol levels; reducing post-prandial blood glucose and/or insulin levels, or increasing sensitivity to insulin; providing energy-yielding metabolites through colonic fermentation. Corn syrup (soluble corn fibre) However, studies reveal that SSF is the most appropriate process in developing countries due to the advantages it offers which make it a cost effective production process [20]. The enzyme acts specifically on the starch molecules alone, leaving the fibers unaffected [2, 4]. Consumers prefer to use cold water and mild conditions which requires the detergent to work in those imitations. Enzymes work at milder conditions when compared to that required by chemical catalysts for operation. With further increase in temperature the enzyme production decreases. Format). Feller, G., Le Bussy, O., & Gerday, C. Expression of psychrophilic genes in mesophilic hosts: assessment of the folding state of a recombinant -amylase. Cellulose Potato starch is the starch found in potatoes. -Amylase (EC 3.2.1.3 ) cleaves (1-6)glycosidic linkages, in addition to cleaving the last (1-4)glycosidic linkages at the nonreducing end of amylose and amylopectin, unlike the other forms of amylase, yielding glucose. There are many potential and widely used applications of this enzyme on the industrial front. Unstandardized foods are foods for which the Food and Drug Regulations or other federal regulations do not provide specific compositional standards. This is then incubated in boiling water bath for 40 min & cooled to room temperature. Bin, G., X. Laisu, D. Youfang and L.

In a study conducted on Penicillium fellutanum the maximum activity of 150 U /ml was obtained when peptone was used as the nitrogen source. "-Amylase Production and Applications: A Review.". Also when used for study of structure function relationships and biochemical properties the enzymes have to be in purified form [2]. Iodine (KI, Iodine) is added to form a colored complex with the starch in the reaction mixture. Recommended label statement: To maintain its fibre properties, this naturally occurring resistant starch should not be exposed to high temperatures or added to foods to be cooked. Derived from potato tubers processed for starch production and obtained through conventional physical procedures (without chemical modification). -Amylase production in B. subtilis Marburg was improvised by treatment with N-methyl-N'-nitro-N-nitrosoguanidine. Also when hydrolysis is carried out at higher temperatures, the polymerization of D-glucose to iso-maltose is minimized [9]. Amylose is prevalent in plants as it is a constituent of starch molecules. The purpose of this document is to provide a positive list of dietary fibres which will help food manufacturers, health professionals, consumers and other interested parties in identifying and using brand name products and generic products assessed as fibre sources and found acceptable by Health Canadas Food Directorate. -Amylase catalyses the first step in this process. Health Products and Food Branch. Pectin 100% amylopectin can be found in the waxy varieties of starches. Common carbon sources used as substrates include maltose, sucrose and glucose. For fungal sources the moisture content required is less whereas bacterial sources need more moisture content for high yield of the enzyme [31]. Carbon makes up only about 0.025 percent of Earth's crust. Starch can attract soil particles on to the clothes. Maltodextrin (soluble corn fibre) All health claims for food must be truthful and not misleading according to Section 5 of the Food and Drugs Act. It is used for biofuel production with starch as a raw material. This is followed by the saccharification process where the starch is hydrolyzed by -Amylase to yield fermentable sugars. Today, Teflon-like compounds called PFAS are found in the blood of almost all Americans. Columnaris. Amylose, amylopectin, maltodextrins. Production of -Amylase from Penicillium chrysogenum was carried out using various agricultural by- products like wheat bran (WB), corncob leaf (CL), rye straw (RS) and wheat straw (WS). The electrophoretic separation also indicates the purity and homogeneity of the enzyme obtained. Beta-glucan concentrated via air classification of dry-milled barley grain. Thermophilic microorganisms such as P. woesei and Thermococcus profundus exhibited optimal production of -Amylase at pH value of 5.0 [55]. In an attempt to produce -Amylase from A. oryzae using coconut oil cake as a substrate, the maximum activity was found to be 1752 U/gds which resulted after 72 h of incubation [43]. from dhal industry waste. Resistant wheat starch or Fungal sources of -Amylase are confined to terrestrial isolates, mostly to Aspergillus species and to only few species of Penicillium, P. brunneum being one of them [12]. The maximum activity was found to be 0.12 U/ml after 90 h and was retained even after 110 h [67]. Resistant potato starch or Novel fibre: modified wheat starch. S-2: purification, characterization, cloning and sequencing. The optimum temperature for production of the enzyme by Bacillus sp. A maximum production of 812 U/g was achieved when peptone was employed as the nitrogen source for -amylase production by P. expansum. Babu, K.

The molecular mass was determined as 55,000 Da from gel filtration method. Increasing sensitivity to insulin. In the falling number method, the enzyme substrate preparations are assayed at 100C. Thermostable -Amylases are desired as they minimize contamination risk and reduce reaction time, thus saving considerable amount of energy. El-Safey, E. M., & Ammar, M. S. Purification and Characterization of -amylase Isolated from Aspergillus falvus var. On hydrolysis of starch this complex changes to a reddish brown colored one. Goto, C.E. Processed through conventional procedures. For determination of molecular weight of purified enzyme produced by mutant Bacillus subtilis, SDS-PAGE (10%) was carried out [70]. Submerged fermentation (SmF) employs free flowing liquid substrates, such as molasses and broths. -Amylase Production and Applications: A Review. The molecular mass of the enzyme can also be determined using size exclusion chromatography [75]. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a The number of steps involved in purification will depend on the extent of purity that is desired [30, 59, 60, 61]. The study revealed that with wheat bran as the substrate, the maximum yield of enzyme was of 295 U/gds with 60% of initial moisture content. The hydrolytic activity of -Amylase can be determined based on the principle that starch and iodine react to form a blue colored complex. Amylose is a much smaller molecule than amylopectin. There are mainly two methods which are used for production of -Amylase on a commercial scale. columnaris, the enzyme was precipitated was followed by dialysis and then column chromatography [68]. Dried exudate from stems and branches of Acacia senegal and Acacia seyal species, processed by water dissolution, purification, concentration and drying. Cellulose: These are occurring in plants and the most abundant organic substance. Amylase Production and Applications: A Review Red algae, or Rhodophyta (/ r o d f t /, / r o d f a t /; from Ancient Greek (rhdon) 'rose', and (phutn) 'plant'), are one of the oldest groups of eukaryotic algae. The four recognized physiological effects of dietary fibres are: Tables 1 and 2 below provide the list of dietary fibres assessed and accepted by Health Canada's Food Directorate. NCBI Bookshelf Fibres sharing similar characteristics are regrouped by category in Table 1. Products identified as "traditional fibres" in the third column of both tables were not considered as novel fibres and their acceptance as sources of fibre was not based on their physiological functionality as dietary fibres. Firstly, the starch is subjected to liquefaction to form a viscous starch suspension. In B. subtilis 29 the optimum temperature for growth (42C) was higher by 5C than that of amylase formation (37C) [40]. Citation-(RIS a hydrogen atom) on a monomer subunit by another covalently-bonded chain of that polymer; or, in the case of a graft copolymer, by a chain of another type.Branched polymers have more compact and Also, the microorganisms can be tailored to cater to the needs of growing industries and to obtain enzymes with desired characteristics like thermostability for example. Format), Citation-(EndNote Standard inulin and long chain inulin obtained by hot water extraction and/or by conventional separation processes. In a study of Amylase production by Preussia minim, the sample was precipitated using trichloroacetic acid (TCA)/acetone and applied to a Sephadex G-200 gel filtration column. high amylose corn starch. The purity was then analysed by using SDS-PAGE [71]. Amylose is a polysaccharide made of -D-glucose units, bonded to each other through (14) glycosidic bonds.It is one of the two components of starch, making up approximately 20-30%.Because of its tightly packed helical structure, amylose is more resistant to digestion than other starch molecules and is therefore an important form of resistant starch. There are two temperatures that need to be in optimum range during production. Cellulose fibers (/ s lj l o s,-l o z /) are fibers made with ethers or esters of cellulose, which can be obtained from the bark, wood or leaves of plants, or from other plant-based material. The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation (K from Koagulation, German for "coagulation") or for controlling binding of calcium in bones and other tissues. The main advantage is that nutrient-rich waste materials can be easily recycled and used as substrates in this method. Kenneth A. Laderman, Bradley R. Davis, Henry C. Krutzsch, Marc S. Lewis, Y. V.

The fructose syrup obtained is used as a sweetener, especially in the beverage industry. Characterization by this method was used for -Amylase produced by C. thermohydrosulfuricum E 101-69. Also the starch hydrolysis decreases the viscosity of the dough, thus improving its texture and increasing loaf volume by rising of dough. Glucose syrup (soluble corn fibre) Obtained from dehulled or hull-less barley grain using standard dry milling techniques, which may include steaming or tempering. Chitin Two methods used to measure enzyme activity in terms of decreasing viscosity of starch suspension are: falling number (FN) method and Amylograph/Farinograph test. Manufacturers who are considering the use of novel fibre sources and require further guidance on the fibre policy or on the content of this document may contact the Bureau of Nutritional Sciences by mail or electronically. To strengthen the thread, sizing agents are used which strengthen the thread by forming a layer on it and can be removed after the fabric is woven. -Amylase (E.C.3.2.1.1) is a hydrolase enzyme that catalyses the hydrolysis of internal -1, 4-glycosidic linkages in starch to yield products like glucose and maltose. The precipitated sample can be subjected to dialysis against water or a buffer for further concentration [68]. The optimum pH for activity is found to be 7.0 [4].-Amylase has become an enzyme of crucial importance due to its starch hydrolysis activity and the activities that can be carried out owing to the hydrolysis. An amyloplast is an organelle that is responsible for starch synthesis and storage in plants. Obtained from sugar beet pulp by pressing, steam drying and milling. All undesirable changes like increase of crumb firmness, loss of crispness of the crust, decrease in moisture content of the crumb and loss of bread flavor together are called staling. A. N., Goma, G. E. R. A. R. D., & Soucaille, P. H. I. L. I. P. P. E. Purification and characterization of the extracellular alpha-amylase from Clostridium acetobutylicum ATCC 824. Bacillus amyloliquefaciens UNG-16 was subjected to mutation by both the chemical (EMS) and radiation method. Derived from blueberry processing and produced through conventional physical procedures (without chemical modification). The enzyme is also used as an anti staling agent to improve the shelf life and softness retention of baked goods [2, 4, 79]. Nielsen, J.E. Starch is a polymer of glucose that exists in two forms: amylopectin and amylose. This can be followed by any of the chromatographic techniques like ion exchange, gel filtration and affinity chromatography for further separation and purification of the enzyme. DuPonts Teflon changed our lives, but also polluted our bodies. In the NS method, an aliquot of stock solution of substrate is heated at 50C for 5min. Values of 400-/600 Brabender units of the Farinograph are found optimal for flour used to bake bread [2]. When beta-amylase breaks down starch, it removes two glucose units at a time, producing maltose. It is found in algae and other lower forms of plants. Thermococcus -Amylases are optimally active at temperatures close to 80C. Q. Amylose is significant in plant energy storage, and it is less susceptible to digestion than amylopectin. Obtained from milling process of high amylose corn grain, followed or not by hydrothermal treatment. The optimal activity was found to be at 45C [45]. In a study of -Amylase produced by Bacillus MNJ23 strain the molecular mass of the enzyme was characterized by SDS-PAGE (12% acrylamide gel) using Bio-Rad miniprotean II electrophoresis unit [74]. Branching (polymer chemistry The isoelectric point of the enzyme can be determined by using protein markers of broad range of pI of values [73]. -Amylase is used to digest the starch containing food particles into smaller water soluble oligosaccharides. In a study of production of the enzyme by Aspergillus oryzae, NaNO3 (0.9%) and malt (1%) gave highest yield of enzyme among many other nitrogen sources [62]. Das, S., Singh, S., Sharma, V., & Soni, M. L. biotechnological applications of industrially important amylase enzyme. This was about 9% higher than the activity obtained by using yeast, meat and casein [12]. The use of chemical catalysts has been followed for a very long time.

The crude extracellular enzyme sample can be obtained from the fermented mass by filtration and centrifugation. Function in the Plant. Maximum -Amylase production of a-amylase by Alteromonas haloplanktis was found at an optimal temperature of 4C [46]. Derived from processing dehulled and defatted soybean flakes in mild alkaline conditions. When solid state fermentation was carried out for production of the enzyme by Penicillium janthinellum in a range of 30-55C, the optimum incubation temperature was found to be 45C [37]. Coronado, M. J., Vargas, C., Hofemeister, J., Ventosa, A., & Nieto, J. J.. Production and biochemical characterization of an amylase from the moderate halophile Halomonas meridiana. The characterization of molecular weight of -Amylase produced by in Pyrococcus furiosus by G Dong, C Vieille et al (1997) was carried out using gel filtration chromatography that employed a column containing Sephacryl S200 with carbonic anhydrase (29,000), bovine serum albumin (66,000), alcohol dehydrogenase (150,000), and Blue Dextran (2,000,000) as standards [76]. Preheated (50C for 5 min) enzyme solution is added to the substrate. The product consists of polymers of glucose containing (1-4) and (1-6) glucosidic bonds, as well as varying amounts of /(1-2), /(1-3), (1-4) and (1-6) bonds. There are 2 major reasons for the increasing interest in microbial sources: 1) The growth of microorganisms is rapid and this will in turn speed up the production of enzyme. Whole or edible parts (pulp, peel) of traditional fruits, vegetables, cereals, legumes, nuts, seeds, etc. Penicillium chrysogenum was used as the microbial source for producing amylase by solid state fermentation using various substrates such as, corncob leaf, rye straw, wheat straw and wheat bran [14]. The study revealed that the amylase exhibited maximal activity at pH 7.0, being relatively stable in alkaline conditions [11]. Thippeswamy, S., Girigowda, K., & Mulimani, V. H. Isolation and identification of alpha-amylase producing Bacillus sp. modified potato starch. The chemical composition of oil cake depends upon the extraction methods used [43]. Aspergillus sp.such as A. oryzae, A. ficuum and A. niger exhibit optimal production at pH 5.06.0 in SmF [47, 48, 49]. Corn maltodextrin (soluble fibre) Starch Once the baking is done, there may be changes during storage of baked products. Sugars are found in the tissues of most plants. Carbohydrates are one of the three macronutrients in the human diet, along with protein and fat. Bala Kumaran M.D and Kalaichelvan P.T., Purification and Characterization of-Amylase and-Galactosidase from. Beta amylases are only found in plants and animals. The majority of oligomers consists of 3 to 6 glucose units. Starch is an odorless, tasteless, soft white substance that is made by all green plants. Oil cakes are byproducts of oil extraction. The sizing also contributes to better quality of the paper in terms of strength, smoothness, writing and erasebility. Followed by 10 min of incubation at 50C, DNS reagent is added to the test tube and the mixture is incubated in a boiling water bath for 5 min. But with increase of moisture content further the enzyme yield decreases owing to many reasons. Maltodextrin corn fibre Whereas the enzymes used clinical and pharmaceutical industry need to be highly purified. They are synthetically produced or are obtained from natural sources which have no history of safe use as dietary fibre or which have been processed so as to modify the properties of the fibre contained therein. Types of Sugar. One such activity is the production of glucose and fructose syrup from starch. Improving laxation or regularity. Fibre declaration and claims are subject to regulatory oversight and manufacturers and importers must be able to disclose the evidence substantiating the safety and the physiological effect of their novel fibre sources in accordance with Health Canada's Policy for Labelling and Advertising of Dietary Fibre-Containing Food Products. Derived from sweet orange processing and produced through conventional physical procedures (without chemical modification). There are 2 types of hydrolases: endo-hydrolase and exo-hydrolase. Bureau of Nutritional Sciences This fermentation technique is suitable for microorganisms such as bacteria that require high moisture content for their growth. Plants are able to synthesize glucose, and the excess glucose, beyond the plants immediate energy needs, is stored as starch in different plant parts, including roots and seeds. Food Directorate It is produced commercially as a white to Obtained from the amylolytic digestion of milled wheat kernel used for ethanol production. Inorganic sources such as ammonium chloride, ammonium phosphate, ammonium sulphate resulted in low yield of enzyme. The disadvantages that this method poses include need for high temperature and pressure for catalysis and the moderate specificity. The hydrolysate composition obtained after hydrolysis of starch is highly dependent on the effect of temperature, the conditions of hydrolysis and the origin of enzyme. The purified enzyme sample along with molecular markers like BSA (67 kDa) and ovalbumin (43 kDa), are run on the gel. Hence, enzymatic hydrolysis is a preferred method. The substrate that -amylase acts upon is starch. Resistant potato starch or Beta-glucan may be partially hydrolysed. Haloalkaliphilic -Amylase isolated from archaebacterium Natronococcus sp. This report focuses on the microbial production of -Amylase and its applications. The crude enzyme sample is incubated at 92C with soluble starch to carry out the reaction for 10 min. An optimal production of 3677 U/g of -Amylase was found at 85% of initial moisture content using a combination of wheat bran and groundnut oil cake as the substrate [60]. Providing energy-yielding metabolites. In a study of purification and characterization of an extracellular -Amylase from Clostridium perfringens Type A, crude enzyme concentrate was prepared by precipitation with polyethylene glycol.
