Embodiment 1

[0031] A processing method of red sea bream collagen polypeptide-chromium (III) chelate, the steps are:

[0032] (1) Raw material pretreatment and decalcification: take real sea bream as raw material, pretreatment such as slaughtering, viscera, head and tail removal, bone removal, etc., then wash the skin and scales and dry them, and crush the fish scales to make fish scale powder 10% lactic acid solution with a mass concentration according to the ratio of solid-liquid mass ratio of 1:15, soaking fish scale powder at normal temperature for 25min;

[0033] (2) Degreasing and de-impurity protein: the fish scale powder and fish skin are degreased with n-hexane under the condition that the ultrasonic frequency is 25kHz, the ultrasonic electric power is 250W, and the mass ratio of solid to liquid is 1:2, and the treatment time is 2h; Then be 25kHz at ultrasonic frequency, under the ultrasonic action of 250W with mass concentration be that 1% sodium chloride carries out impurity rem...

Embodiment 2

[0038] A processing method of red sea bream collagen polypeptide-chromium (III) chelate, the steps are:

[0039] (1) Raw material pretreatment and decalcification: take real sea bream as raw material, pretreatment such as slaughtering, viscera, head and tail removal, bone removal, etc., then wash the skin and scales and dry them, and crush the fish scales to make fish scale powder 15% lactic acid solution is used to soak the fish scale powder at normal temperature for 20 minutes according to the ratio of solid to liquid mass ratio of 1:20;

[0040] (2) Degreasing and impurity protein removal: degrease the fish scale powder and fish skin with n-hexane under the conditions of ultrasonic frequency of 50kHz, ultrasonic electric power of 500W, and material-to-liquid mass ratio of 1:3 respectively, and the treatment time is 3h ; then under the ultrasonic frequency of 50kHz, ultrasonic electric power is 500W with mass concentration of sodium chloride to degreasing fish scale powder, ...

Embodiment 3

[0045] A processing method of red sea bream collagen polypeptide-chromium (III) chelate, the steps are:

[0046] (1) Raw material pretreatment: using real sea bream as raw material, pretreatment such as slaughtering, viscera, head and tail, and bone removal, etc., then the fish skin and scales were washed and dried, and the fish scales were crushed to make fish scale powder. Soak fish scale powder at room temperature for 15 minutes in a solution with a concentration of 20% according to the ratio of 1:25;

[0047] (2) Degreasing and removing impurities: the fish scale powder and fish skin were degreased with n-hexane under the conditions of ultrasonic frequency of 80kHz, ultrasonic electric power of 800W, and solid-liquid mass ratio of 1:5, and the treatment time was 4h. then under the action of ultrasound that the ultrasonic frequency is 80kHz and the ultrasonic electric power is 800W, the fish scale powder and fish skin after degreasing are carried out to remove impurities re...

Abstract

The invention relates to a method for processing red sea bream collagen polypeptide-chromium (III) chelate. The method comprises the following steps: taking fish skin and fish scale of the red sea bream as raw materials, crushing the fish scale into fish scale powder, soaking the fish scale powder into lactic acid to decalcify, respectively degreasing the fish powder and the fish skin by using normal hexane under the ultrasonic action, and removing other protein from the fish powder and the fish skin under the ultrasonic-sodium chloride synergistic action; performing enzymolysis to the fish powder and the fish skin according to a certain ratio by using trypsin, deodorizing the hydrolysate by using active carbon powder to obtain collagen peptide solution and spray drying to prepare powder;crushing and mixing the collagen peptide powder and CrCl3.6H2O completely, performing microwave solid phase chelation reaction, dissolving by adding absolute ethanol to remove non-chelate, and dryingthe undissolved substance to obtain the collagen polypeptide-chromium (III) chelate. The preparation process of the collagen polypeptide-chromium (III) chelate is safe and pollution-free, so that effective and high-value utilization of the fish processing low-value byproducts or leftovers such as fish skin and fish scale is realized, the utilization ratio of the raw materials is high, the processing cost is low, and important social and economic significance is achieved.

Description

technical field [0001] The invention belongs to the field of aquatic product processing, and in particular relates to a processing method of red sea bream collagen polypeptide-chromium (III) chelate. Background technique [0002] The processing rate of aquatic products in my country is less than 30%, of which the processing rate of fish products is less than 10%, and the processing of leftovers is even less. In the processing of aquatic products, fish skin and scales are used as leftovers, and their utilization rate is very low. Except for a small part used in the tanning industry, most of them are discarded as waste. The nutritional value and function of fish skin and scales have no Get full play, but also pollute the environment. [0003] Chromium (III) not only affects substance metabolism, but also has a certain antioxidant effect. At the same time, a large number of studies at home and abroad have shown that the lack of chromium in the human body is related to type II ...
