Problems solved by technology

The two reported methods are unable to carry out more accurate quantitative detection of donkey-hide gelatin-derived components, but to determine the authenticity of donkey-hide gelatin by detecting whether donkey-hide gelatin contains donkey components and excluding other animal-derived components; but the donkey-hide gelatin Adulteration may be varied, so there will be a variety of animal-derived ingredients that need to be excluded. There are important flaws in using the exclusion method to identify the authenticity of donkey-hide gelatin, and its accuracy and reliability will be greatly reduced. This situation is very unfavorable to the market for donkey-hide gelatin. regulation of products

Embodiment 1

[0033] 1 Materials and Reagents

[0034] Materials: All kinds of pure glue, including donkey-hide gelatin, horsehide glue, yellow gelatin, pigskin glue, sheepskin glue, fish skin glue (the reference substance detection matrix), donkey skin, horse hide, cowhide, pigskin, sheepskin, Obtained by decocting fish skin.

[0035] Donkey-hide gelatin cake: made by adding rice wine, rock sugar, black sesame, and walnut kernels to the above-mentioned pure glue, including a donkey-hide gelatin cake sample made of donkey-hide gelatin (the donkey-hide gelatin accounts for about 23% of the total weight of the donkey-hide gelatin cake), horse hide The fake donkey-hide gelatin cake made from gelatin (the content of donkey-hide gelatin is 0%), the fake donkey-hide gelatin cake made from yellow gelatin (the donkey-hide gelatin content is 0%), the fake donkey-hide gelatin cake made from pig skin glue (the donkey-hide gelatin content is 0%) The content is 0%), and the fake donkey-hide gelatin cak...

[0059] 1 Materials and Reagents

[0060] Material:

[0061] The mixed gum samples were prepared by adding different qualities of donkey-hide gelatin to the pure gum sample in Example 1, including yellow gelatin containing 15% donkey-hide gelatin, yellow gelatin containing 30% donkey-hide gelatin, and yellow gelatin containing 60% donkey-hide gelatin.

[0062] Donkey-hide gelatin cake: made by adding rice wine, rock sugar, black sesame, and walnut kernels to the above-mentioned mixed gum samples, including donkey-hide gelatin cake samples made from yellow gelatin with 15% donkey-hide gelatin (the donkey-hide gelatin accounts for about 3.5% of the total weight of the donkey-hide gelatin cake) ), a donkey-hide gelatin cake sample made with 30% donkey-hide gelatin yellow gelatin (the donkey-hide gelatin accounts for about 6.9% of the total weight of the donkey-hide gelatin cake), a donkey-hide gelatin cake sample made with 60% donkey-hide gelatin yellow gelatin (the donkey-hide ge...

Abstract

The invention discloses a composition and detection method for detecting the content of donkey-hide gelatin in donkey-hide gelatin cakes. The composition is composed of a polypeptide I, a polypeptide II, a polypeptide III and a reference substance detection matrix; the amino acid sequence of the polypeptide I is shown as SEQ ID NO. 1; the amino acid sequence of the polypeptide II is shown as SEQ ID NO. 2; the amino acid sequence of the polypeptide III is shown as SEQ ID NO. 3; the reference substance detection matrix is fish skin glue. The composition can be used for detecting the content of donkey skin source components in the donkey-hide gelatin cakes, so that whether the donkey-hide gelatin is faked or not is judged. A detection value of the polypeptide II is subtracted from the detection value of the polypeptide I and detection deviation is corrected by utilizing the detection value of the polypeptide III, so that the detection of the content of the donkey skin source components in the donkey-hide gelatin cakes is realized. The method has the advantages of accuracy in content detection and simplicity in operation and has a wide application prospect.

Description

technical field [0001] The invention relates to a composition of donkey-hide gelatin content in donkey-hide gelatin cake and a detection method thereof, belonging to the technical field of medicine and food detection. Background technique [0002] As the saying goes: "Tonic in autumn and winter, to fight tigers in the coming year." Donkey-hide gelatin is a dual-purpose food material, which has the functions of nourishing yin and blood, and is a good tonic for autumn and winter. The main eating method of donkey-hide gelatin is to boil donkey-hide gelatin with rice wine, add black sesame seeds, walnut kernels, etc., and process it into donkey-hide gelatin cake for consumption. However, as the price of donkey-hide gelatin has risen year by year, many lawbreakers have appeared in the market. When producing donkey-hide gelatin, some or all of them are cooked with various other animal skins, including horse hide, mule hide, cowhide, pig skin, etc., instead of donkey hide. Some a...
