The invention discloses a formula and a preparation method of protolysate-based
liquid food. The formula is specifically prepared from 3 to 7 parts of
protein, 1 to 5 parts of fat, 12 to 25 parts of
carbohydrate, 1 to 4 parts of composite minerals, 0.5 to 3 parts of composite vitamins, 0.2 to 1.5 parts of
emulsion stabilizer and the balance of water. According to the protolysate-based
liquid food prepared by the invention, intolerant symptoms of
diarrhea in different degrees,
abdominal distension and the like after the taking of the protolysate-based
liquid food are prevented from happening, and the requirement of patients on enteral
nutrition is met; the occurrence rate of gastrointestinal adverse reaction is reduced, the absorption speed of the
protein is increased, and the purposes of maintaining an
intestinal mucosa function and supplementing the
protein are achieved; a liquid
enteral nutrition preparation prepared through super-high temperature instant sterilizing is time-saving, needs not to be prepared and is short in
operation time, so that the liquid
enteral nutrition preparation is not easily polluted by
bacteria; but a
powder enteral nutrition preparation can be applied through a certain amount of warm boiled water, and the application is more time-consuming, so that obvious difference exists in
operation time. According to the protolysate-based liquid food disclosed by the invention, the occurrence rate of the gastrointestinal adverse reaction is reduced, the
absorption rate of the protein is increased, and the purposes of maintaining an
intestinal mucosa function and supplementing the protein are achieved.
