Description
Technical Field
The invention belongs to the technical field of dairy product processing, and relates to modified milk, in particular to zero-lactose modified milk with browning reaction by using Maillard reaction and a preparation method thereof.
Background
As is well known, dairy products are gradually becoming ideal natural nutritional foods for human beings due to the fact that the dairy products contain rich nutritional elements, and are indispensable in modern family life, and with the continuous improvement of the living standard of people, more people begin to pay attention to the flavor and nutrition of milk.
The modified milk is a liquid product prepared by taking raw milk or reconstituted milk with the content of not less than 80 percent as a main raw material, adding other raw materials or food additives or nutrition enhancers according to the nutritional requirements of different people and adopting proper processes of sterilization, disinfection and the like. From the aspect of nutrition, some nutrients of the modified milk may be diluted compared with pure milk, such as well-known protein, and according to the relevant national standard, the protein content of the pure milk is more than 2.8 g/100g, and the protein content of the modified milk is more than 2.3 g/100g, but the difference is negligible, and the protein content of some modified milk with good quality in the market can even reach more than 3.0 g/100 g. It should be further noted that some of the nutritional components of some of the modified milks may be enhanced to better meet the needs of the human body.
However, some people may suffer from noninfectious diarrhea after taking ordinary milk or modified milk, because some people lack lactase in vivo and cannot completely digest and decompose lactose in breast milk or cow milk, that is, lactase deficiency, which is what we say is lactose intolerance. Lactase deficiency is a widely existing worldwide problem, the peak age range of lactose intolerance in different countries is different, Japan is 7-8 years old, Africa is 3-5 years old, and the research of 1168 healthy children in Beijing, Shanghai, Guangzhou and Harbin 4 cities in China suggests that the occurrence rate of lactase deficiency is high, and 87% of children lactose intolerance occurs in 7-8 years old. China belongs to a high-incidence area with lactose intolerance, the problem of lactose absorption and utilization is gradually aroused by people along with the improvement of living standard, so that low lactose or zero lactose becomes one direction for consumers to pursue, the milk with low lactose in the market at present has the lactose content of more than 0.6g/100g (ml), and is still not suitable for some serious people with lactose intolerance to eat, while the zero lactose in the market mostly has no mouthfeel of adding nearly pure milk, and the product with good mouthfeel of the zero lactose in the domestic market is almost not available.
Brown lactose-free milk does not appear in the current market, and the traditional milk browning method usually adopts the traditional process and utilizes the addition of exogenous reducing monosaccharide, so that the constant-temperature browning time is long, and the nutritional value is greatly reduced.
