Embodiment 1

[0030] In the reactor, 40g of canna starch was dissolved in 100mL of distilled water to prepare canna starch milk with a concentration of 40% (w / v, on a dry basis), and the pH of the starch milk was adjusted with 3% NaOH solution. Turn it up to 9.

[0031] At a reaction temperature of 40° C., 1.2 g of OSA (diluted in 5 times the volume of absolute ethanol) was evenly added within 1 hour. In order to prevent alcoholysis of OSA, it must be prepared on site. At the same time, use 3% (W / V) NaOH solution to control the pH value of the system and keep it stable at around 9.

[0032] After continuing the reaction for 1.5h, adjust the pH value to 6.5 with 3% (W / V) HCl solution, wash twice with 75% (V / V) ethanol and distilled water, dry in an oven at 40°C after dehydration, and grind through 100 mesh Sieve to obtain octenyl succinic acid canna starch ester, and seal the bag for storage. The degree of substitution of canna starch octenyl succinate was determined to be 0.01018 by pickl...

Embodiment 2

[0037] In the reactor, dissolve 30g of canna starch in 100mL of distilled water to prepare starch milk with a concentration of 30% (w / v, based on dry basis weight), and use 3% (W / V) NaOH solution to dissolve the starch The pH of the milk was adjusted to 9.

[0038] At a reaction temperature of 30° C., 0.9 g of OSA (diluted in 5 times the volume of absolute ethanol) was evenly added within 1 hour. In order to prevent alcoholysis of OSA, it must be prepared on site. At the same time, use 3% (W / V) NaOH solution to control the pH value of the system and keep it stable at around 9.

[0039] After continuing to react for 3.5 hours, adjust the pH value to 7.0 with 3% (W / V) HCl solution, wash twice with 75% (V / V) ethanol and distilled water, dry in a 40°C oven after dehydration, and grind through 100 mesh Sieve to obtain octenyl succinic acid canna starch ester, and seal the bag for storage. The degree of substitution of canna starch octenyl succinate was determined to be 0.00919 by...

Embodiment 3

[0041] In the reactor, 35g of canna starch was dissolved in 100mL of distilled water to prepare starch milk with a concentration of 35% (w / v, on a dry basis), and the starch milk was mixed with 3% (W / V) NaOH solution. The pH of the milk was adjusted to 8.5.

[0042] At a reaction temperature of 35° C., slowly add 1.05 g of OSA (dilute it in 5 times the volume of absolute ethanol) within 1 hour. In order to prevent alcoholysis of OSA, it must be prepared on site. At the same time, use 3% (W / V) NaOH solution to control the pH value of the system and keep it stable at about 8.5.

[0043] After continuing to react for 2.5 hours, adjust the pH value to 6.8 with 3% (W / V) HCl solution, wash twice with 75% (V / V) ethanol and distilled water, and dehydrate to obtain octenyl succinic acid plantain Taro starch ester, sealed bag preservation. The degree of substitution of canna starch octenyl succinate was determined to be 0.01118 by pickling method. The resistant starch content of the ...

Abstract

The invention relates to an octenyl succinic acid cannaedulisker starch ester and a preparation method thereof. At present, the raw materials of starch for preparing octenyl succinic acid starch ester are limited to corn and some potato starch without researching octenyl succinic acid cannaedulisker starch ester almost. According to the octenyl succinic acid cannaedulisker starch ester, cannaedulisker starch is used as a raw material, and octenyl succinic acid anhydride is used as esterifying agent; the octenyl succinic acid cannaedulisker starch ester prepared by a conventional wet method is relatively large in product viscosity and relatively high in transparency and gelatinization degree, and has better emulsibility, thickening propery, freeze-thaw stabilization and retrogradation stabilization; the content of resistant starch in the product is more than 30%; and the octenyl succinic acid cannaedulisker starch ester serves as a functional food additive to be applied to the field of food processing, particularly in frozen and baked food.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a starch octenyl succinate and a preparation method thereof. Background technique [0002] Starch octenyl succinate is prepared by esterification of octenyl succinic anhydride and starch. Compared with the original starch, it has higher hydrophobicity. Therefore, it has both hydrophilic and hydrophobic properties. It is widely used in food, cosmetics, textile, paper, and pharmaceutical industries, which greatly improves the quality of starch products. Starch octenyl succinate is a highly safe emulsifying thickener, which has been approved for use by major countries in the United States, Europe and the Asia-Pacific region. [0003] At present, there are few manufacturers of starch octenyl succinate in China, and the product structure is relatively simple, so it is urgent to increase research and development efforts to develop starch octenyl succinate series products to meet the wid...
