Description

Rice wine collagen jelly and preparation method thereof
Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a preparation method of rice wine collagen jelly.
Background
The jelly as a leisure food has crystal and transparent appearance, bright and gorgeous color, soft, smooth and crisp mouthfeel and fresh, sweet and moist flavor, and wins consumers, especially children and teenagers. However, most of the currently marketed jellies are processed by using thickening agents, coloring agents, essences, sweeteners and the like as main raw materials, are not easy to digest, and can influence the absorption of human bodies on nutritional ingredients such as protein, fat, trace elements and the like when being eaten too much. With the enhancement of health consciousness of consumers, the requirements on leisure food are higher and higher, and the quality of the jelly is more and more emphasized. The traditional jelly is a high-sugar and high-acid product, and has high calorie and low nutritive value. Therefore, the development of a leisure, nutritional and healthy jelly product meets the modern consumption concept and the trend of food development, and has wide market prospect.
The rice wine is also called glutinous rice wine, fermented glutinous rice and fermented glutinous rice, and is a traditional Chinese alcohol-containing food. The traditional rice wine can be directly eaten after fermentation or eaten after heating and boiling, and is fragrant, sweet and mellow in taste and low in ethanol content, so that the rice wine is popular with people. However, the traditional rice wine has poor instant property and is inconvenient to eat at any time and any place.
Collagen is a biological macromolecule, a main component in the connective tissue of animals, and is also a functional protein with the largest content and the widest distribution in mammals, accounting for 25-30 percent of the total protein, and even reaching more than 80 percent of certain organisms. The types of collagen are many, and the common types are type I, type II, type III, type V and type XI. Collagen has good biocompatibility, biodegradability and bioactivity, and thus is widely used in the fields of food, medicine, tissue engineering, cosmetics, and the like. The collagen can inhibit activities such as lipid oxidation and microorganism metabolism in food to a certain extent. The amino acids composing the protein have stronger absorption capacity and water retention capacity, and further can inhibit the water loss in the food. At present, the price of the collagen product on the market is high, and the requirement of common consumers on the collagen product is difficult to meet. Therefore, the development of a collagen leisure food which has high universality, high collagen content and easy absorption is of great significance.
