Benefits of technology

This patented method simplifies the manufacturing processes while increasing both contents (stalk) and yields of slowly dissolving or non-dissolved starch compared to traditional methods like cooked rice flour. By utilizing this natural sources instead of fossil resources, it reduces environmental impact without compromising flavor attributes such as taste. Additionally, the use of specific types of starchy grains called tapioca makes them easier to produce due to their unique structure that allows quicker breakdown during heat treatment. Overall, these technical results improve the efficiency and cost effectiveness of producing stable and effective starch derivatives suitable for various applications including food industry, medical supplies, pharmaceuticals, cosmetic industries, etc., which could help address issues related to diabetes and obese people' s needs worldwide.

Problems solved by technology

This patented describes different methods used during production to increase the amount of certain substances found naturally occurring within an edible material called starchy gum. These techniques include mixing it with other materials like gluten flour or rice grains before cooking them. By doing these things we aim to create a stable ingredient containing specific types of compounds such as sugars, amino acids, fats, minerals, phytochemistry elements, antioxidants, antihypertensives, fibers, etc., resulting in improved taste sensations when eaten alone compared to regular wheatmeans.

Embodiment 1

[0025] Weigh 1 g of raw starch to make a starch milk solution with a concentration of 1%, and then cook it at 100°C for 2 minutes to make it completely gelatinized; after the starch paste is cooled to room temperature, add 50 mL of Tris-HCl buffer solution and Sucrase made into 100mM sucrose solution and 0.5U / g starch; at 30°C, pH 6.5, constant temperature reaction for 24h; after inactivating enzyme treatment, the enzymolyzed product was dried and pulverized to obtain rich slow-digestible starch Low glycemic starch derivatives with resistant starch. It has been determined that the contents of slow digestible starch and resistant starch in the product are respectively increased by 30% and 13% compared with the original starch, and the ratio range of short chain (DP13) in the chain structure is 0.47.

Embodiment 2

[0027] Weigh 1g of raw starch to make a starch milk solution with a concentration of 12%, and then cook it at 80°C for 25min to make it completely gelatinized; after the starch paste is cooled to room temperature, add 70mL Tris-HCl buffer solution and 500mM sucrose solution and 40U / g starch sucrase; at 45°C and pH 7.3, constant temperature reaction for 2h; A low glycemic starch derivative of resistant starch. It has been determined that the contents of slow digestible starch and resistant starch in the product are respectively increased by 19% and 15% compared with the original starch, and the ratio range of short chain (DP13) in the chain structure is 0.29.

Embodiment 3

[0029] Weigh 1g of raw starch to make a starch milk solution with a concentration of 30%, and then cook it at 90°C for 10 minutes to make it completely gelatinized; after the starch paste is cooled to room temperature, add 100mM Tris-HCl buffer solution and sucrose to make it 1000mM sucrose solution and 95U / g starch sucrase; at 50 ℃, pH 8.0 conditions constant temperature reaction 48h; A low glycemic starch derivative of resistant starch. It has been determined that the contents of slow digestible starch and resistant starch in the product are respectively increased by 24% and 19% compared with the original starch, and the ratio of short chain (DP13) in the chain structure is 0.13.

Abstract

The invention discloses a method for preparing low blood sugar starch by enzymatic modification, which belongs to the technical field of deep processing of starch. The method biologically modifies and recombines a starch molecular chain fine structure after commercialized massive starch products of corn starch, wheat starch, rice starch, potato starch, cassava starch, sweet potato starch and the like are pasted by using the hydrolysis catalyzing technology of sucrase so as to obtain low blood sugar starch derivatives rich in slow-digestion starch and resistant starch; and the content ratios of the slow-digestion starch and the resistant starch in the low blood sugar starch product are improved by 15 percent and 10 percent respectively compared with the primary starch. The application and the development of the product relate to a plurality of fields of food, medicament and the like; and the low blood sugar starch is not only the medicinal food for diabetes, obesity, hypertension and cardiovascular disease patients, but also can be used as special food for athletes slowly releasing continuous energy or ideal health-care food for healthy people.
