Protein nutritive jellies prepared from oviductus ranae enzymatic hydrolysate and byproduct

The invention belongs to the technical field of health-care food, and particularly relates to an oviductus ranae functional peptide nutritive jelly and an oviductus ranae enzymolysis byproduct protein nutritive jelly. The jellies adopt oviductus ranae functional peptide and unhydrolyzed oviductus ranae as protein enhancers and the mixture of carrageenan, gelatin and xanthan as gelatinizer, white granulated sugar, citric acid, potassium sorbate and essence are applied to regulate the flavor, the products are clear in color and transparent, the taste is delicate, the elasticity is moderate, and the jellies are chewy; the hardness of the textures is moderate, and air bubbles do not exist; the taste and the smell are moderately sour and sweet, and the jellies do not have the fishy smell of oviductus ranae. The preparation process for the jellies mainly includes two parts, i.e. the preparation of the oviductus ranae functional peptide and the preparation of the protein nutritive jellies. The inspected quality indexes of the protein nutritive jellies disclosed by the invention fully meet product standards, and since the protein nutritive jellies respectively contain the oviductus ranae functional peptide and the collagen, the protein nutritive jellies have the effects of enhancing the immunity of the human body, reducing blood fat and blood sugar, maintaining beauty and the like, and is significant in guaranteeing the physical health of people.
