Method for identifying sugar-doped dried sea cucumber

Abstract

The invention discloses a method for identifying a sugar-doped dried sea cucumber. The method is characterized by comprising the following steps of: vibrating and extracting exogenous sugar in the sea cucumber in a water bath at certain temperature by using an aqueous solution of ethanol at high concentration, wherein polysaccharide in the dried sea cucumber cannot be extracted, so that endogenous sugar and the exogenous sugar in the dried sea cucumber can be identified well; and measuring the total content of the extracted sugar by using an optimized phonel-sulfate method. The method is easyto operate, and high in stability and high in accuracy, and is suitable for measuring the total content of the exogenous sugar in the dried sea cucumber; and by the method, the sugar-doped dried sea cucumber can be effectively identified.

Description

Technical field:

[0001] The invention relates to the field of quality identification of aquatic products, in particular to a method for identifying dried sugar-mixed sea cucumbers. Background technique:

[0002] Sea cucumber is a nutritious food with high protein content and balanced amino acids and trace elements. It contains about 76.5g of protein, 1.1g of fat, 13.2g of polysaccharide-based sugars, calcium, phosphorus and iron per 100g of pure dry product. , iodine and other beneficial minerals 4.2g. In addition, sea cucumbers also have high medicinal value. According to medical records, sea cucumbers can nourish the kidney and replenish essence, and have certain curative effects on the treatment of tuberculosis hemoptysis, aplastic anemia, diabetes, etc., and have been favored by people for a long time.
