Description

A kind of preparation method of probiotic brown lactobacillus beverage product with large amount of bacteria
Technical field
The invention belongs to milk products technology category, relate in particular to a kind of preparation method of probiotic brown lactobacillus beverage product with large amount of bacteria.
Background technology
Along with the development and progress of society, people's life expectancy constantly prolongs; Meanwhile, people pursue quality of life more, and longevity also needs healthy, and the stomach and intestine of function harmony are healthy bases.If often take probio, can effectively keep or recover the gut flora balance.
According to Food and Agricultural Organization of the United Nations/World Health Organization in 2002 definition of (Food and Agriculture Organization is called for short FAO/World Health Organization and is called for short WHO), probio is the microorganism that lives, when taking in liberal quantity, the host is produced the functional health benefit that one or more have demonstration.
Probio have regulate the intestinal flora balance, improve intestinal environment, immunity is infected, is regulated in defaecation, prevention, reduce cancer allergic reaction takes place, slows down, reduce functions such as cholesterol, because of bacterial strain different.
Exist hundreds of different microorganism in the human digestive road, wherein contain beneficial bacterium, neutral bacterium and harmful bacterium, quantity can reach 100,000,000; Generally, they keep certain ecological balance relation each other.
But usually because a variety of causes as improper diet, tired, nervous, infection, use antibiotic etc., gets muddled the gut flora balance.In society now, though economical increase fast, the people's income significantly improves, and rhythm of life is accelerated, and operating pressure increases, and dinner party is many and diet is owed science, causes gut flora unbalance easily.Harmful bacterium breeding occupies advantage, sub-health state occurs, even disease takes place.
In general, all genus active product of probiotic products, at present most of sour milk beverage all is by ordinary lactic acid bacteria on the domestic market: allocate forming behind streptococcus thermophilus and the bulgaria lactobacillus fermentation, and bacterium to count content low, or deactivation type product.Like this, product is by behind the human body hydrochloric acid in gastric juice, and the probio quantity that can survive seldom can not farthest be brought into play its prebiotic effect behind the arrival enteron aisle.
Will keep the viable count of probio in the milk fermentation goods to greatest extent, be the emphasis of current research always, the dairy products of prior art, and probios such as active Bifidobacterium wherein, Lactobacillus casei are poor to low pH value tolerance, easily by the hydrochloric acid in gastric juice deactivation; Very responsive to oxygen, the problem that causes the viable bacteria amount to descend rapidly such as inactivation is needed solution badly easily under aerobic conditions.
Maillard reaction is called non-enzyme browning reaction again, is also referred to as browning reaction; It is a kind of non-enzymatic browning that extensively is present in food industry, it is the reaction between carbonyls (recuding sugars) and amino-compound (amino acid and protein), intend melanocyte through final macromolecular substances melanoidin or the title that generates brown or even black of complicated course, so claim the reaction of carbonyl amine again.The product of Maillard reaction is brown, and carbonyls comprises aldehyde, ketone, reduced sugar in the reactant, and amino-compound comprises amino acid, protein, amine, peptide.The result of this reaction can make food colour deepen and give food certain local flavor.Maillard reaction product has non-oxidizability, and autoxidation shows non-oxidizability, useful health to the brown stain pigment that produces in the Maillard reaction to the grease class.
Summary of the invention
The application's goal of the invention is the above-mentioned defective at prior art, develop a kind of can about 37 ℃, the fermentation, its commodity can tolerate the human stomach acid environment, preserve and have the preparation method of the sour milk beverage product of the high viable count that arrives the human intestine of living.
