摘要:
본 발명은 저단백미 제조방법 및 제조장치에 관한 것으로, 더욱 상세하게는 단백질 분해효소 반응액을 최적의 pH와 온도에서 계속적으로 순환시켜 줌으로써 순환되지 않는 정치식으로 반응시키는 것보다 상층부와 하층부의 효소반응액의 pH 차이가 없게 유지시켜 주어 효소반응 효율성이 향상되고 단백질 제거 효과가 매우 높아질 뿐만 아니라, 간헐적으로 폭기를 시켜 줌으로써 대량의 쌀을 처리하더라도 효소반응액에 균일하게 노출될 수 있기 때문에 단백질 제거가 더욱 효과적이며, 이로써 무균포장밥과 같은 공업화를 위한 저단백미 제공이 가능한 저단백미 제조방법 및 제조장치에 관한 것이다.
摘要:
The present disclosure relates to an enzyme blend comprising a low pH, thermostable alpha-amylase and a Bacillus licheniformis alpha-amylase. The blend can include at least about 1.0 Liquefon Unit (LU) of the B. licheniformis alpha-amylase for every 5.0 Modified Wohlgemuth Unit (MWU) of the low pH, thermostable alpha-amylase. The enzyme blend described is suitable for starch liquefaction and saccharification, ethanol production, and/or sweetener production, among other things. Also provided herein is a method of processing a starch by liquefying the starch with the low pH, thermostable alpha-amylase and the Bacillus licheniformis alpha-amylase, simultaneously or sequentially.
摘要:
Method for reducing the amount of asparagine in a processed whole grain composition comprising treating the composition with asparaginase for a period of from 2 to 60 minutes at a moisture content of from 15 to 45 % by weight and a temperature of from 20°Cto50°C.
摘要:
A method comprising selection of unbroken whole grain rice that are first washed, or whole grain corn that is first reduced in size, and then making an aqueous slurry that is subsequently wet milled to release all the protein, fat, fiber, and starch components normally held in the structure of the grain. The resulting slurry can be reacted with heat to gelatinize the starch and the subsequent product dried. Also, the heated slurry containing the liberated components can be treated to enzymatic hydrolysis via the process of liquefaction and optionally saccharification, producing whole grain rice milk products having diverse carbohydrate compositions. The whole grain milk products are characterized by a nutritional composition containing substantially all the nutritional components of the whole grain, being an opaque whole milk colloid, having smooth texture versus pulpiness, lacking in all bitterness normally associated with whole grain products, and having a variety of sweetness levels from non-sweet to very sweet.

摘要:
The present invention relates to a process for producing a rice protein concentrate from a rice substrate comprising, enzymatically hydrolyzing a rice substrate with an enzyme having granular starch hydrolyzing (GSH) activity and a second starch hydrolyzing enzyme at a temperature at or below 72° C and at a pH of about 3.0 to 6.5 to obtain a solubilized starch fraction and a residue fraction which includes insoluble protein, and separating the solubilized starch fraction from the residue to obtain a rice protein concentrate. The rice protein concentrate may be used in animal feed and human food formulations.
摘要:
This invention discloses a method for preparing rice starch, which includes steps of: a) making rice into rice powder, then paste to PH7-12 and 10-22Be°; b) heating to 40-70°C for 5-30hours; c) based on total weight, adding 0.2-0.6wt% protease and paste to PH7-12 and 10-22Be°; d) dehydrating; e) washing, dehydrating again, drying. The rice starch obtained by this method is also disclosed, and it contains 0.01-0.3wt% protein and more than 55wt% starch, based on total weight.
摘要:
The invention relates to a preparation comprising an active phytase, a phytate and an essential cation, said preparation being characterized in that at least part of the essential cation is bound to phytate. The preparation may comprise between 1 and 100 FTU phytase per gram phytate, between 1 and 50 g essential cation bound to phytate and between 50 and 99 g of phytate per 100g of essential cation bound to phytate. The essential cations are selected from the group consisting of calcium, zinc, iron, magnesium, cobalt, molybdenum, manganese, chromium, copper or a combination thereof. The preparation may comprise an additional component such as a chelating agent and/or an antioxidant. The invention also relates to a method for making the preparation of the invention and to its use for making a fortified food product. The invention also relates to a condiment, a cereal product or a soymilk comprising an active phytase.
摘要:

Preferably the oxidoreductase is at least capable of oxidizing maltose.
摘要:
A dietary fiber material obtained by using enzymes to digest cereal grains. The enzymes substantially hydrolyze any starch occurring in the cereal grain into small molecules but only partially hydrolyze ß-glucan molecules. The dietary fiber material can have excellent physicochemical, physiological, and sensory properties such ass low molecular weight, a particular molecular weight distribution, and a particular polydispersity, in addition to having excellent food ingredient properties. As a food ingredient, the material can have high ß-glucan content which provides nutrient to the body. Because the dietary fiber material can have neutral mouthfeel, it can be used to enhance the nutritional content of ice cream, yogurt, baked goods, bars, beverages, or certain other foods-without affecting the taste or other sensory attributes of the food. As a further benefit, the dietary fiber material can be used to provide certain therapeutic benefits, such as anticholesterol activity.
