Embodiment 1

[0020] A preparation method of an iron supplement nutritional fortifier, comprising the steps of:

[0021] The first step uses acetic acid-sodium acetate buffer to adjust the mass concentration of potato starch milk to 15%, the pH value is 6.5, and the temperature is 50 ° C. Add α-amylase (BAN 480L, Novozymes (China) Investment Co., Ltd.), Add 300 u of α-amylase per gram of dry starch, react for 30 hours, neutralize with 0.1 mol / L hydrochloric acid to pH 6.2, wash, dry at 40°C to a moisture content of 14%, and pulverize to obtain enzymatic starch.

[0022] The second step is to adjust the mass concentration of enzymatic starch to 82% with water, seal it in a container, react at 140°C for 5 minutes, cool to room temperature, dry at 45°C until the moisture content is 14%, and grind to obtain wet heat treated starch.

[0023] In the third step, the wet heat treated starch is made into starch milk with a mass percentage of 20% by ferric chloride solution, the concentration of ferr...

[0027] A preparation method of an iron supplement nutritional fortifier, comprising the steps of:

[0028] The first step uses acetic acid-sodium acetate buffer to adjust the mass concentration of cassava starch milk to 40%, the pH value is 4.5, and the temperature is 30°C, adding α-amylase (BAN 480L, Novozymes (China) Investment Co., Ltd.) and Glucoamylase (Dextrozyme DXW, Novozymes (China) Investment Co., Ltd.); add 450u of α-amylase and 30u of glucoamylase per gram of dry starch, react for 4 hours, and neutralize with 0.2mol / L sodium hydroxide solution pH to 6.5, washed, dried at 50°C to a water content of 12%, and crushed to obtain enzymatic starch.

[0029] The second step is to adjust the mass concentration of the enzymatic starch to 70% with water, seal it in a container, react at 90°C for 12 minutes, cool to room temperature, dry at 50°C until the moisture content is 13%, and grind to obtain wet heat treated starch.

[0030] In the third step, the wet heat treated sta...

Embodiment 3

[0033] A preparation method of an iron supplement nutritional fortifier, comprising the steps of:

[0034] The first step uses acetic acid-sodium acetate buffer to adjust the mass concentration of cornstarch milk to 25%, the pH value is 5.0, and the temperature is 45°C, adding glucoamylase (Dextrozyme DXW, Novozymes (China) Investment Co., Ltd.); Add 600 u of glucoamylase to the dry starch, react for 12 hours, neutralize with 0.1 mol / L sodium hydroxide solution to pH 6.4, wash, dry at 45°C until the water content is 13.8%, and crush to obtain enzymatic starch.

[0035] The second step is to adjust the mass concentration of enzymatic starch to 75% with water, seal it in a container, react at 120°C for 60 minutes, cool to room temperature, dry at 40°C until the moisture content is 14%, and grind to obtain wet heat treated starch.

Abstract

The invention discloses a method for preparing an iron supplement nutritional enhancer. The method comprises the following steps of: preparing starch milk with the mass concentration of between 15 and 40 percent from a starch raw material by using acetic acid-sodium acetate buffer solution; adding amylase into the starch milk to react at the temperature of between 30 and 55 DEG C; neutralizing, washing, drying and crushing to obtain enzymatic starch; preparing enzymatic starch with the mass concentration of between 70 and 82 percent by using water, reacting for 5 minutes to 12 hours at the temperature of between 80 and 140 DEG C, and cooling, drying and crushing to obtain heat-moisture treated starch; preparing starch milk from the heat-moisture treated starch by using ferric chloride solution, and reacting for 3 to 40 hours under stirring; and neutralizing, washing, drying and crushing to obtain a product. The product is rich in ferric metal trace elements, can be used as the iron supplement nutritional enhancer for foods and health-care products, is favorable for improving the condition that acceptable daily intake of life essential trace elements is not sufficient and protecting the health of people, and is a functional food additive with high additional value.

Description

technical field [0001] The invention relates to a production method of modified starch, in particular to a method for preparing a starch-iron metal complex nutrition enhancer by combining biotechnology, physical methods and chemical methods. Background technique [0002] Fat, protein, carbohydrates, vitamins, trace elements (minerals), and water are the six major nutrients that human beings depend on for survival. With the development of social industrialization and the improvement of living standards, the dietary structure and lifestyle of Chinese residents have changed. Excessive or unbalanced nutrition has led to a relatively common phenomenon of insufficient and unbalanced intake of trace elements in our population, triggering Cardiovascular disease, diabetes, tumor, cerebrovascular disease, senile anemia and other diseases are increasing year by year. Trace elements refer to elements that account for less than 1 / 1000 of the body weight and require less than 100 mg per ...
