Enzymatic extraction of soybean dietary fiber
oundstheprocessingandmethodofusingbielogi-calproteaseandlipasetOmakeSOybcanfibre. Keywords: soybeanfibre; protease; lipase0 introduction of high nutritional value of soybeans, up to 40% dry weight protein, soy protein isolate production process 30% to 35% of the soybean residue; processing of tofu, soy milk produce 50% of the dregs. In modern times, has become the world's industrialized areas of soybean production scale, and soybean residue as a by-product of soybean processing enterprise, has long been the main job of livestock feed, low added value, and cause high production costs, low economic efficiency, plagued the development of processing enterprises . Okara is a rare source of dietary fiber, high fiber content, fiber texture, taste good, can be processed into high purity, high quality, high value-added, application of a wide range of low-calorie dietary fiber. In Japan, the United States, Australia, bean dregs of food have been achieved industry. Japan, Du Yan Dan strains can produce the dietary fiber and oligosaccharides,[link widoczny dla zalogowanych], insoluble drying microencapsulation of Bifidobacterium with science that is probiotics, supply the elderly and young children. Significant business benefits. Western Europe will be processed directly added dietary fiber, staple food, the food world on Australia's dregs. 1 Materials 1.1 Materials soybean residue: from the student cafeteria: 1.2 Reagents Protease: food grade. Wuxi Genencor Biological Engineering Co., Ltd.: Received date; 2000-04-03 Author: Luo Light ~, k (1946 A), male, professor of Xi'an University of Technology scraping T2. 'Q-Sf lipase: ibid; buffer: H: O. 2.1 Production Method 2 process dregs bleaching,[link widoczny dla zalogowanych], softening _ + protease lipase hydrolysis of a rinse of a washing of a filter of a dehydration of a screening of a dry and finely ground _ a one of a bleach rinse a filter dewatering of a modification of a dry and a smash 2.21 a finished 2.2 points rinsing process, softening the standard weighing and make okara softening rinse with water. 2.2.2 Hydrolysis conditions for hydrolysis is 50. c, pH8.0, solid-liquid ratio l: 10, a certain amount of enzyme, reaction 8, a lOh. During the reaction time by adding a buffer to maintain the same DH. 2.2.3 Hydrolysis of fat hydrolysis conditions 40'E, pH7.5, solid to liquid ratio of 1:10, a certain amount of enzyme, reaction 6-8h, during the same by adding a buffer to maintain pH. 2.2.4 Rinse all treated soybean residue with water rinse to neutral fiber. Dehydrated with 225 filter to rinse the plate and frame filter fiber dehydration. 2.26 after drying the dehydrated bean dregs fiber evenly placed on a baking tray,[link widoczny dla zalogowanych], release the blast drying oven to 11O ℃ 4 ~ 5h, to dry up. 2.2.7 Accurately weigh bleaching purpose of okara fiber fine grinding to 40, according to solid-liquid ratio l: 8 plus 4% of people concentration of Hm, to 60% water bath, constant temperature bleaching lh. 2.2.8 crushing, modified, enhanced use of the current increase of the more popular parts of water-soluble dietary fiber content in the way of a method of enzymatic and mechanical shear mechanical shearing method for ultrafine grinding and strengthen the ca \, zn other trace elements. 3 Summary of the enzyme used in food technology, so in the process must control the production of a variety of conditions such as temperature, pH, enzymatic activity when the substrate concentration and dosage. At the same time must be kept the site clean,[link widoczny dla zalogowanych], because if cross contamination can inhibit enzymatic activity, thus affecting production. With the improvement of human life, the food people eat more and more sophisticated, resulting in the consumption of dietary fiber content decreased cause like diverticulosis, colon cancer,[link widoczny dla zalogowanych], diabetes, obesity increases the incidence. this conscious food adding a certain amount of dietary fiber on the prevention of the disease and the maintenance of human nutritional balance is important.
