Example Embodiment

[0018] Example 1

[0019] Weigh 16.68g of Cigu starch with a water content of 10.08% and add 283mL of water, mix well to prepare Cigu starch milk with a concentration of 5% (g / mL); put the mixed Cigu starch milk in a beaker and place it on a dual-frequency ultrasonic device Carry out ultrasonic treatment in the middle of ultrasonic frequency 20+40kHz, ultrasonic power 300w, ultrasonic 10s, intermittent 2s, total ultrasonic time 40min, ultrasonic temperature 30 sound temperature, and stir the starch milk of Cigu during the ultrasonic process; put the processed starch milk of Cigu statically After a period of time, the upper layer of liquid is poured out, and the remaining starch is dried in a 50 o'clock drying box to 7%-10%; the dried Cigu starch is crushed with a pulverizer to obtain a dual-frequency ultrasonic modified Cigu starch.

Example Embodiment

[0020] Example 2

[0021] Weigh 16.68g of Cigu starch with a water content of 10.08% and add 283mL of water, mix well to prepare Cigu starch milk with a concentration of 5% (g / mL); put the mixed Cigu starch milk in a beaker and place it on a dual-frequency ultrasonic device Carry out ultrasonic treatment in the middle, the ultrasonic frequency is 20+60kHz. The other conditions were the same as in Example 1, and the dual-frequency ultrasonic modified Cigu starch was obtained.

Abstract

The invention discloses a double-frequency ultrasonic modification method of arrowhead starch, and belongs to the technical field of processing of agricultural products. A finished product is prepared from arrowhead starch through preparation, double-frequency ultrasonic modification treatment, drying and crushing. The structure and the physicochemical characteristics of the arrowhead starch undergoing the double-frequency ultrasonic modification treatment are greatly changed, so the application range of the arrowhead starch is greatly enlarged. Compared with traditional starch modification methods, the modification method disclosed in the invention has the advantages of short time, small energy consumption, convenience in operation, safety, no pollution, and easiness in industrial production.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a method for preparing sagittarius modified starch by using double-frequency ultrasonic waves. Background technique [0002] Arrowhead Arrowhead is an important economic crop for both medicine and food in China. It has a wide planting area and high yield in my country, and is loved by consumers. Sagittarius is a high-starch plant, starch accounts for about 50% of its dry matter content, and its amylose content is more than 30%, which belongs to the starch type with high amylose content. This special structure makes sagittarius starch easy to regenerate, which affects the use quality of sagittarius starch. Therefore, it is of great significance to carry out relevant research on the quality characteristics of sagittarius starch, which will help to improve the structure and physical and chemical properties of sagittarius starch, and expand the ap...
