Disclosure of Invention

The invention aims to provide vomiting-preventing infant yak formula milk powder, which can effectively relieve the physiological gastroesophageal reflux phenomenon of a baby, protect the young and tender esophagus of the baby, and can fully utilize the nutritional ingredients of yak milk or full-fat yak milk powder.

In order to achieve the purpose, the invention adopts the following technical scheme:

the vomiting-preventing infant yak formula milk powder is characterized in that the main raw materials for producing each ton of products are as follows: 750kg of yak milk and/or 37.5-112.5kg of full-fat yak milk powder, 900kg of raw milk, 10-30kg of whey protein powder, 500kg of whey powder, 80-240kg of OPO structural grease, 0.5-5kg of walnut oil, 2.5-7.5kg of isomerized lactose liquid, 9-27kg of fructo-oligosaccharide, 12-36kg of galacto-oligosaccharide and 1-3kg of locust bean gum.

Preferably, the addition amount of locust bean gum for a period of 0-6 months old infants (weight 2.7-8.8Kg) is 3 Kg/ton; the addition amount of locust bean gum for 2 segments (weight 8.8-11.3Kg) of older infants of 6-12 months is 2.1 Kg/ton; the addition amount of locust bean gum to 1-3 years old children (weight 11.3-16.4Kg) is 1.2 Kg/ton.

Locust bean gum (Locust/Carob bean gum/CBG), also known as Locust bean gum, Carob bean gum, is derived from the endosperm fraction of the seed of the Locust tree, is a natural food thickener, the main component of which is galactomannan. Locust bean gum is a water-soluble colloid with low concentration and high viscosity.

Infants develop milk regurgitation mainly due to gastroesophageal reflux (GER). GER refers to a series of symptoms and complications caused by the reflux of stomach contents (including gastric acid and pepsin) into the esophagus and parts outside the esophagus (e.g., throat, mouth, lungs). The main causes of gastroesophageal reflux in infants are the following 4 points 1, underesophageal sphincter (cardia) has not developed completely: after the infant eats, the cardia can not contract well, so that the stomach milk flows back to the esophagus; 2. small stomach volume: the secretion of gastric juice is less, the activity of digestive enzyme is low, and dyspepsia is easy to occur, so that flatulence is caused; 3. the feeding mode is improper: feeding of the infant causes air and milk to be sucked into the stomach together, and milk is easily spit when the infant burps or shakes; in addition, excessive feeding tends to cause regurgitation in infants; 4. feeding while lying, coupled with the short esophagus of infants, is also a large cause of reflux. It has been found that properly thickening a formula can reduce the incidence of milk regurgitation in infants. The locust bean gum is a good natural thickener, and less than 1 percent of the locust bean gum is added into the milk powder, so that milk can be more easily deposited at the bottom of the stomach of an infant, and does not easily flow back to the esophagus and the parts except the esophagus.

Preferably, the desalting rate of the whey powder is more than or equal to 90%.

Preferably, the OPO structure oil and fat mainly comprises 1, 3-dioleate 2-palmitic acid triglyceride.
