Embodiment 1
[0037] This embodiment provides a kind of brown fermented milk, and this brown fermented milk is prepared by the following steps:
[0038] (1) Skim reduction and lactose hydrolysis: Add 86kg of pure water to the mixing tank, heat up to 40°C, then add 16kg of skim milk powder and 0.1kg of hydrolase into the tank, stir evenly, and let it stand for 2 hours to obtain reconstituted milk ;
[0039] (2) Browning of reconstituted skim milk: heating the reconstituted milk obtained in step (1) to 80° C., keeping it for 3 hours, and then cooling down to 40° C. to obtain brown reconstituted skim milk;
[0040] (3) Fermentation of defatted reconstituted milk: put 20dcu / 100kg of strains into the defatted fermented milk obtained in step (2), heat-preserve and ferment for 120 hours, and terminate the fermentation to obtain brown fermented milk.
[0041] Wherein, the skimmed milk powder is New Zealand medium-temperature skimmed milk powder, the hydrolase is lactose hydrolase, and the strain i...
Embodiment 2
[0043] This embodiment provides a kind of brown fermented milk, and this brown fermented milk is prepared by the following steps:
[0044] (1) Skimming recovery and lactose hydrolysis: Add 86kg of pure water to the mixing tank, heat up to 50°C, then add 16kg of skimmed milk powder and 0.1kg of hydrolase into the tank, stir evenly, and let stand for 0.5 hours to obtain reconstituted milk ;
[0045] (2) Browning of reconstituted skim milk: heating the reconstituted milk obtained in step (1) to 100° C., keeping it for 0.5 hours, and then cooling down to 30° C. to obtain brown reconstituted skim milk;
[0046] (3) Fermentation of skimmed reconstituted milk: put 30dcu / 100kg strains into the skimmed fermented milk obtained in step (2), heat-preserve and ferment for 40 hours, stop fermentation, and obtain brown fermented milk.
[0047] Wherein, the skimmed milk powder is Australian medium-temperature skimmed milk powder, the hydrolase is lactose hydrolase, and the strains are Lactob...
Embodiment 3
[0049] Compared with Example 1, the only difference is that in this example, the raw materials for preparing brown fermented milk are: 80kg of purified water, 10kg of skim milk powder and 0.05kg of hydrolase.
