The world health organization released statistics results show that the global at present at least 1 billion people are overweight, 300 million obesity.Obesity caused by high blood pressure, heart disease and other cardioascular disease (CD) has said that losing weight fitness has become the focus of concern.At present is mainly to lose weight by dieting, exercise and weight loss products and so on, to achieve the goal of thin body, reduce weight.The weight loss products on the market mainly divided into appetite suppressant drugs such as tea, increase energy expenditure and inhibit the intestinal digestion and absorption of drugs, have some side effects, and easy to rebound.At present, added enzyme (enzyme) is considered to be more health and safety of method reducing weight, popular in Japan and Taiwan of China.Especially in Japan, the development of enzyme products for hundreds of years of history, eating "enzyme" became the Japanese longevity and health habits.　　As the FDA recently recommended by an enzyme preparation to lose weight, contains lipase, protease and amylase enzyme weight loss agent and so on the many kinds of enzymes.Lipase hydrolyzed fat, accelerate the decomposition of body fat, promote fat elimination;Protease, can edible protein hydrolysis of peptide, provide the body with protein and a small amount of other sources of heat and keep the body and nitrogen balance, strengthen the absorption of proteins, accelerate the excretion and body toxin exclusion, reduce fat accumulation, healthy weight loss.Ex. :(1) enzyme functional food recipes to lose weight(See table)　　(2) the advantages and characteristic: to promote the decomposition of fat, protein and starch in food into the human body can absorb directly using the component, lower viscosity, liquidity enhancement, not the body residual and accumulation, hydrolysis to remove the body of the original sediment at the same time, provides the nutrition for the human body, achieve the goal of healthy weight loss.

Food enzymes from biological (including animals, plants, microorganisms) to extract the substances capable of biocatalysis, supplemented by other ingredients, used to accelerate the process of food processing and products to improve the quality of food products.Enzyme in production when using for the food industry must conform to the relevant state quality standards。Food enzymes as a food additive is added to the food, the only play a role in machining process, a substance that help finish a shift, and once it is completed the mission, will retire, disappear or lose energy in the final product.Will not harm residues in food.Food enzymes specificity in its catalytic properties, catalytic faster, natural environmental protection features, such as in food production and is playing a more and more important role in people's life.The enzyme preparationApplications in food (bread baking industry, flour processing, fruit processing industry, etc.), textile, feed, detergent, paper making, leather, medicine and energy development, environmental protection, etc.Enzymes derived from biological, generally safer, according to the production need to use.Enzymes mainly include the following9Categories: saccharifying enzyme, amylase, cellulose enzyme, proteinase, phytase, hemicellulase and pectinase compound enzyme, forage composite enzyme, beer.Can be used alone, also can be mixed use, for example, tender fish belongs to the papain, such as: Fried dough sticks Peng Song enzyme contains The protease, amylase, belongs to the distribution of enzymes.

Enzymes as natural pollution-free food additives, and gradually to be the concern of the industry.Scientific and reasonable to add can significantly improve the baking quality, quality, nutritional quality, prolong its shelf life.Below to related enzyme preparation industry to do a simple introduction for reference.A, amylaseAmylase is able to break down starch glycosidic bond of the floorboard of the kind of enzyme, including alpha amylase, beta amylase, saccharifying enzyme and amylase, commonly used have alpha amylase and saccharifying enzyme.1, the alpha amylaseAlpha amylase, also known as 1, 4 - dextrin starch enzyme, alias for liquefied amylase, the optimum pH value of 5.0 ~ 7.0 optimum temperature on different sources of difference is bigger, in the production of this enzyme microorganism bacillus subtilis, aspergillus Niger and aspergillus oryzae and rhizopus.Improving bread flexibility, strengthen the extension and emphysematous, volume increases, the introduction made good tactility foreign skin color also has a good effect.2, fungi of alpha amylaseFungi of alpha amylase referred to as "the FAA, derived from aspergillus oryzae, a proteolytic enzyme, fungus of alpha amylase activity has a more stable and do not contain protein enzyme activity, the optimum pH value is 4.0 ~ 5.0 optimum temperature is 50 ℃ ~ 60 ℃.Mainly have the following effect:(1) provide nutrients for yeast.(2) improve the bread softness, to enhance the extension and emphysematous, volume increase, after make feel better.(3) to improve bread skin colour and lustre.3, bacteria of alpha amylaseBacteria of alpha amylase is generally heat-resistant bacillus subtilis alpha amylase with fungi on the mechanism of alpha amylase have certain difference.The optimum pH is 5.0 optimum temperature is 80 ℃ ~ 90 ℃.Alpha amylase is rotting anti-aging ability.4, saccharifying enzyme,Saccharifying enzyme called alpha 1 starch, saccharifying enzyme mainly produced by mold and rhizopus, optimum pH value of 4.0 ~ 5.0 optimum temperature of 55 ℃ ~ 60 ℃.Good resistance to acid, at 25 ℃, pH3.0, stable earnings and not reduce, pH2 cases, stable 55 hours.Bread add color and flavor, can be used in the frozen dough.Make the yeast in the dough can soon its role in the depth of frozen dough.Second, the xylanaseXylanase used in baking is known, it is a kind of pentosan enzyme, its hemicellulose enzymes play a most important role, its dosage than traditional hemicellulose enzymes, the optimum pH for 4 ~ 6, optimum temperature 50 ℃ ~ 60 ℃.To improve the operating performance of the dough and the stability of the dough, increases the product volume, improve the quality of the finished product.Three, glucose oxidase (GOD)Glucose oxidase (GOD) system named beta - D - glucose REDOX enzyme, found in the aspergillus Niger and grey green mold.Generally produced by aspergillus enzyme and, its optimal effect pH: 3.5 ~ 7.0, the optimum effect of temperature: 50 ℃ ~ 60 ℃.Can improve the dough gluten strength, enhance the elasticity, has better tolerance to mechanical shock.

Food enzymes production use of health regulations are as follows:(1) according to good manufacturing technology to produce enzymes, must achieve food grade.(2) according to the variety of food hygiene standards of microorganism, enzyme preparation and processing of food must not cause increase of total microbe.(3) enzyme preparation processing of food must be increased to, or harm health magazine.(4) used in the production of industrial strains of food enzymes, must be a pathogenic, do not produce toxins, antibiotics, hormones and other physiological active substances, must pass safety testing, to be used.

Enzyme preparation in production when using must conform to the relevant national quality standards, product standards should include physical and chemical and health standard.Product physical and chemical standards shall be formulated by the competent department in charge of hygiene standards shall be formulated by the departments jointly with the department of health, products should be according to the inspection rules, qualified rear can leave the factory.For enzyme of animals for food industry, should be based on "meat hygiene inspection procedures for inspection, must comply with the measures for the administration of the meat and meat products health of meat and quarantine requirements.For enzyme preparation plants, food industry should be edible not rot bad food.For microbial enzyme preparation, food industry should be determined by the national committee for preservation properties and kinds of names, and confirmed as safe production.
