Embodiment 1

[0030] Example 1: Brown stirred yoghurt containing morels was prepared using the following method:

[0031] (1) Clean and drain fresh morels, then dry them in stages, at 40°C for 7 hours, at 55°C, and dry until constant weight. After crushing, pass through a 300-mesh sieve to obtain a particle size of ≤50 μm The hickory chick powder; fresh Hericium erinaceus is dried, pulverized, sieved, and the obtained Hericium erinaceus powder is added in the mass percent and is 1% in the cellulase solution, and the material-liquid ratio of Hericium erinaceus to cellulase solution is 1:10g / mL, adjust the pH of the solution to 6, and enzymatically hydrolyze it at 55°C for 4 hours to obtain Hericium erinaceus juice.

[0032] (2) Prepare 85 parts of goat milk, 3 parts of morel powder, and 3 parts of Hericium erinaceus juice in parts by weight. Treat the goat milk at 10°C with a homogenization pressure of 25MPa for 10 minutes, and then sterilize it at 85°C Process 20s.

[0033](3) Add 3 parts...

Embodiment 2

[0036] Embodiment 2: adopt the following method to prepare the brown stirred yoghurt containing morel:

[0037] (1) Wash the fresh morels, drain them, dry them in two stages, dry at 35°C for 5 hours, dry at 50°C until constant weight, crush them, and pass through a 300-mesh sieve; dry and crush Hericium erinaceus Finally, after sieving, add the mass percent to 0.5% cellulase solution, enzymolysis at 55°C for 4 hours, the pH of the solution is 6.5, the material-liquid ratio of Hericium erinaceus and cellulase solution is 1:8g / mL, Filter to get Hericium erinaceus juice.

[0038] (2) Prepare 85 parts of goat milk, 2 parts of morel powder, and 3 parts of Hericium erinaceus juice in parts by weight. Treat the goat milk at 4°C with a homogenization pressure of 30MPa for 15 minutes, and then sterilize it at 90°C Processing 30s.

[0039] (3) Add 2 parts of morel powder, 3 parts of Hericium erinaceus juice, 4.3 parts of sucrose, and 1.7 parts of fructose into 85 parts of goat milk, s...

Abstract

The invention discloses a brown stirred yoghurt containing morel powder and a preparation method thereof. The stirred yoghurt comprises the following components in mass percent: 2-3 parts of morel powder, 1-2 parts of Hericium erinaceus juice , 80-85 parts of fresh milk, 4-6 parts of mixed sugar, 3-4 parts of compound starter, 0.3-0.5 part of emulsification stabilizer; the mixed sugar is composed of sucrose and fructose with a mass ratio of 2-2.5:1. The preparation method of the brown stirred yoghurt comprises the following steps: raw material preparation, homogenization, browning, fermentation, post-ripening, and the stirred yoghurt prepared by the method has stable properties. The stirred yoghurt prepared by the invention has a moderate color, solves technical problems such as difficulty in fermentation of high-sugar fermentation of milk (goat milk) after long-term high-temperature browning, poor fermentation flavor and tissue state, and the product has excellent burnt flavor and fermentation flavor , the tissue state is even and delicate, and the fermentation time is short and the quality is high. Combined with the special effects of Morchella and Hericium erinaceus, it is suitable for all kinds of people.

Description

technical field [0001] The invention relates to a yogurt and a preparation method thereof, in particular to a browning stirring type nutritional yogurt and a preparation method thereof. Background technique [0002] Stirred yogurt is made by stirring and mixing the auxiliary materials and the yogurt gel obtained after fermentation. Compared with ordinary yogurt, it has the characteristics of diversified taste and richer nutrition. The product features are mainly determined by the auxiliary materials added during stirring. . [0003] Brown yogurt is a low-viscosity drinkable yogurt, which is an emerging yogurt drink. Because the protein and reducing sugar in the raw milk undergo a Maillard reaction at a suitable temperature, that is, carbonyl compounds (reducing sugars) and amino compounds (proteins) are condensed. , dehydration, degradation, cracking, polymerization and a series of reactions to generate melanin-like substances, and has a special caramel aroma, which is quit...
