Description
Technical field
The present invention relates to a kind of milk powder, specifically, relate to a kind of milk powder being rich in dietary fiber and preparation method thereof.
Background technology
Dietary fiber is a kind ofly not easy to by the nutrient of human consumption, large quantity research shows, dietary fiber has important to human body to be physiological function, to absorb the digestion that enough dietary fibers contribute to food, also can angiocardiopathy preventing, cancer, diabetes and other physiological maladies many.
Because dietary fiber has important physiological function, be more and more used in the production of adult formula's milk powder, to improve the physiological function of formula milk, but the cost of dietary fiber is higher, and a large amount of interpolation can increase the production cost of product.
At present, generally use maltodextrin as batching in adult's milk formula, the present invention adds amylorrhexis maltodextrin and prepares dietary fiber in the production process of adult formula's milk powder, formula milk finished product is made to have the dietary fiber of certain content, the simultaneously dietary fiber 1 prepared of the method, 4-glycosidic bond content is less, contributes to the rising controlling glycemic index.
Summary of the invention
One object of the present invention is to provide a kind of preparation method being rich in the milk powder of dietary fiber.
Another object of the present invention is to the milk powder being rich in dietary fiber providing described method to prepare.
For reaching above-mentioned purpose, on the one hand, the invention provides a kind of preparation method being rich in the milk powder of dietary fiber, described method comprises after adding maltodextrin in milk solution, add amylomycin enzyme hydrolysis obtain described in be rich in the milk powder of dietary fiber.
Milk solution of the present invention can be former milk, can, for the liquid milk product obtained after former milk processing process, can be also even the milk solution of preparation after milk powder dissolving; It can be even any mixing of former milk, liquid milk product or milk powder; For example be preferably raw milk and/or skimmed milk power.
The milk that wherein the present invention is preferably described is further milk.
When the present invention uses former milk to prepare, can also preferably by after former milk acceptance(check), centrifugal, pasteurize, after cooling, batching, adds fungal amylase again and is hydrolyzed after homogeneous.
