Technical Field

The invention relates to a double-protein nutrition-enriched meat rice paste substrate for old infants and a preparation method thereof, belonging to the technical field of development of complementary food for infants.

Background

The growth and development of the older infants (7-36 months) are rapid, and the nutrition and development at the period are very important for the recent health conditions of individual growth, intelligence development, immunologic function and the like and the health conditions after the adults. And the transition from complete breast feeding to complementary feeding of the infants at this stage is the golden period of nutrition supplementation. However, since the nutritional components required by older infants are the same as those required by adults, the nutritional requirements per kilogram of body mass per day are higher than those of adults, and it is necessary to provide supplementary foods with high nutritional density and high energy density to provide energy and various nutrients required for growth and development under limited gastric containment conditions.

Aiming at complementary food products for old infants, rice paste and muddy meat products on the market are various at present. Although meeting partial nutritional requirements, the comprehensive nutrition needed by older infants is not considered well, and malnutrition symptoms occur. Even some products have poor dissolvability and high viscosity, and neglect the conditions of poor chewing ability and poor digestion ability of infants. In addition, many products additionally contain various additives in order to stimulate the appetite of infants, and the weakness of the digestive system of infants interferes with formula milk or breast feeding after long-term use. Under the background that most of products are single in component and monotonous in form and the complementary food products which well combine meat products and rice paste staple foods appear, it is necessary to create a novel meat and rice paste base which can avoid the disadvantages, so that other nutrients can be conveniently enhanced.
