Low-lactose formula powder and preparation method thereof

Abstract

The invention provides low-lactose formula powder and a preparation method thereof. The low-lactose formula powder is prepared by a dry-wet mixing technique, lactose is replaced with glucose syrup tobe used as a source of carbohydrate, whey protein and casein are added, and an ideal aminogram is achieved; in addition to mixed vegetable oil, long-chain fat DHA and ARA, medium-carbon chain fat MCTand short-chain fat emulsion fat anhydrous cream are added, so that the fatty acid spectrum is balance, and the addition of the short-chain fat enhances the palatability; meanwhile, glutamine is addedto repair intestinal tract. The low-lactose formula powder contains multivitamin and microelement as well as linoleic acid, alpha-linolenic fatty acid, DHA, nucleotide and the like which are requiredby 0 to 6-month infants each day, and the content conforms to the national standard; the lactose content in the formula is relatively low (less than 1.0 g / 100g), which can better meet the health requirement of low-lactose 0 to 6-month infants with lactose intolerance; various defects in the prior art are effectively overcome, and high industrial utilization value is realized.

Description

technical field [0001] The invention relates to the technical field of dairy products, in particular to a low-lactose formula powder and a preparation method thereof. Background technique [0002] Lactase deficiency is a widespread worldwide problem. Lactase deficiency is related to factors such as race, heredity, and geographical environment. According to a survey by the Institute of Nutrition and Food Hygiene, Chinese Academy of Preventive Medicine, Orientals are more lactose intolerant. More, 22.1% at 3 to 5 years old, 39.0% at 7 to 8 years old, 36.8% at 11 to 13 years old, more adults. my country is a country with a high incidence of lactose intolerance. The incidence of this condition is 75% to 95% among Han adults, and 76% to 95.5% among ethnic minorities. People with severe lactose intolerance account for more than 20% of the population. [0003] For infants aged 0-6 months, secondary lactose intolerance is more common, often caused by diarrhea, and rotavirus enterit...

Problems solved by technology

The most common treatment method is milk fermentation and adding lactase. The metabolism and absorption of lactic acid in the body no longer requires the participation of lactase. Therefore, compared with milk, the symptoms of lactose intolerance caused by yogurt are milder, or by adding milk to milk. Lactase hydrolyzes lactose to reduce lactose content, but when the lactose concentration is as low as 0.8%, such a low substrate concentration is not conducive to the reaction between the substrate and the enzyme in terms of enzymatic hydrolysis technology, and it is difficult to achieve efficient desugaring The effect is a technical barrier in the current dairy industry
