preparation example Construction

[0023] One embodiment of this application provides a preparation method of silkworm pupa protein powder, including:

[0024] Dry the dry silkworm pupa and crushed it for sub -treatment, and get the material one;

[0025] Once the material is soaked in alkaline, centrifugation, collecting precipitation to get material two;

[0026] Drink the material of the material to get the material three;

[0027] Material three is used for Marada to get silkworm pupa protein.

[0028] In this embodiment, the dehydration treatment is: mixing the ratio of dry silkworm pupa and petroleum ether according to the proportion of the material to 1: 4, the constant warm water bath is abandoned for 4h under 50 ° C, and after three times, 3000 R / min is 5min. Remove the liquid liquid, and then wash and dry at 60 ° C to get the materials after skipping.

[0029] In some specific embodiments, the drying temperature is 60 ° C.

[0030] In some specific embodiments, the alkali immersion is added to the materia...

Abstract

The invention provides silkworm chrysalis protein powder and a preparation method thereof, and discloses a preparation method of silkworm chrysalis protein aiming at the problem that the conventional silkworm chrysalis protein deodorization mode cannot be directly applied to food manufacturing at present. The method effectively removes odor characteristic substances dibutyl phthalate and isobutyric acid in the silkworm pupa protein, enhances flavor components of the silkworm pupa protein, and enhances palatability of the silkworm pupa protein applied to food.

Description

Technical field [0001] The present invention involves the field of food, which specifically involves a silkworm pupae protein powder and its preparation methods. Background technique [0002] Silkworm pupae not only have high protein content, but also the proportion of 18 common amino acids is also balanced. It is also rich in active ingredients such as linolenic acid and sub -damage. It has a physiological and health care effect such as strengthening spleen, soothe, ejaculation, and aphrodisiac. resource. However, the water solution of the silkworm pupa's answer is poor, and it is difficult to remove the odor and pigments contained in it, which hinders its resource utilization. [0003] The smell of silkworm pupa protein mainly comes from hydrolyzed small molecular fatty acids, polyamine and glandular secretions. Its main characteristic substances are diode and isopytic acid. At present, the deodorization methods that have been reported include microorganisms, chemistry and phys...
