Embodiment 1

[0036] In this embodiment, the low-temperature enzymatic processing of single-grain Gorgon starch and the synchronous processing method of instant Gorgon protein powder and Gorgon coarse powder are as follows:

[0037] 1. Gorgon seed kernels are crushed and homogenized. Weigh 100kg of Gorgon seed kernels, clean up impurities, crush them, and pass through a 100-200 mesh sieve to obtain Gorgon powder; add 10 times the volume of deionized water to the obtained Gorgon powder, soak for 2-4 hours, and homogenize at a high speed to obtain Gorgon powder slurry.

[0038] 2. Low temperature enzymatic hydrolysis. Add 1-1.5 kg of neutral protease to the Gorgon seed slurry, and enzymatically hydrolyze it below 50°C for 4 hours.

[0039] 3. Solid-liquid separation. After the enzymatic solution is separated at low speed, the upper layer solution is poured out, and then centrifuged at a high speed to obtain the supernatant (1). After concentration and drying, it becomes instant gorgon prot...

Embodiment 2

[0041] In this embodiment, the low-temperature enzymatic processing of single-grain gorgon starch and the synchronous processing method of gorgon protein beverage and gorgon starch are as follows:

[0042] 1. Gorgon seed kernels are crushed and homogenized. Weigh 100kg of Gorgon seed kernels, clean up impurities, crush them, and pass through a 100-200 mesh sieve to obtain Gorgon powder; add 12 times the volume of deionized water to the obtained Gorgon powder, soak for 2-4 hours, and homogenize at a high speed to obtain Gorgon powder slurry.

[0043] 2. Low temperature enzymatic hydrolysis. Add 1-1.5 kg of neutral protease to the Gorgon seed slurry, and enzymatically hydrolyze it below 50°C for 4 hours.

[0044] 3. Solid-liquid separation. Separation of the enzymolysis solution at low speed, pouring out the upper layer solution, and then performing high-speed centrifugation to obtain the supernatant (1), the precipitate is single-grain Gorgon starch, with a yield of 65-70%; ...

Abstract

The invention discloses an enzymatic synchronous processing method for single-grain Gorgon fruit raw starch and related products. Using Gorgon fruit seed kernels as raw materials, aiming at the characteristics of Gorgon fruit starch particles such as fine grain size, aggregation of aggregates, intertwining of protein and starch granules, etc., the method uses protease at low temperature Hydrolyze the protein to separate the original aggregated Gorgon starch granules, and then combine the variable speed repeated centrifugation to separate the single-granule Gorgon starch from protein and Gorgon coarse powder, and finally obtain high-purity single-grain Gorgon starch and instant Gorgon There are two products of protein powder and gorgon powder. By adopting this technology, single-grain gorgon starch with a purity of more than 90% can be obtained, and the starch yield is more than 60%. At the same time, instant gorgon protein powder and a small amount of gorgon coarse powder can be obtained.

Description

technical field [0001] The invention relates to the field of food, in particular to an enzymatic synchronous processing method of single-grain gorgon starch and related products. Background technique [0002] Gorgon fruit is the mature seed kernel of Euryaleferox Salisb. (Euryaleferox Salisb.), also known as chicken head rice. Gorgon is an annual aquatic herb. Its seeds are spherical, covered with a hard shell about 1mm thick, and the inside is starchy kernel, that is, Gorgon. Gorgon is a traditional Chinese medicine raw material in my country, has a variety of physiological and health functions, and is regarded as the top grade for prolonging life. Gorgon fruit is a kind of starch-based raw material, in which the starch content is 77.6% to 78.2%, the crude protein content is close to that of rice, which is 9.72%, and the fat content is low. [0003] Scanning electron microscope observations showed that the starch in the endosperm of Gorgon seed kernels existed in the form...
