Problems solved by technology

The paper "Optimization of germinated soybean polypeptide-enriched culture medium components by response surface methodology" (Bai Qingyun et al. Food Science, 2011, 32(24): 172-177), optimizes the enrichment of soybean polypeptide and other functional substances through the culture medium, However, there are differences in its principle, culture medium components and phytic acid in the germination method.

Embodiment 1

[0019] Vigorous soybean grains are used as raw materials. After disinfection and soaking according to known techniques, the grains are placed in a germination machine and germinated at 33°C for 4 days. The spray liquid uses 0.25mmol / L citric acid solution. The degradation rate of phytic acid in soybean sprouts was 15%.

Embodiment 2

[0021] Vigorous soybean grains are used as raw materials. After disinfection and soaking according to known techniques, the grains are placed in a germination machine and germinated at 33°C for 4 days. The spray liquid uses 1.0mmol / L citric acid solution. Phytic acid degradation rate in soybean sprouts is 25%

Embodiment 3

[0023] Use active mung bean seeds as raw materials, sterilize and soak according to known techniques, put the seeds into a germination machine, germinate at 33°C for 4 days, and use 16mmol / LCaCl as the spray liquid 2 solution and a mixture of 1.5mmol / L citric acid solution. The degradation rate of phytic acid in mung bean sprouts reaches 40%.

Abstract

The invention relates to a production technology of low phytic acid bean sprouts, which is characterized in that the bean grains with physiological activity are used as raw materials, soaked in 0.05% (w / v) NaHCO3 solution for 3 hours, and then placed in a germination machine. Germinate at 33°C; during this period, use 16-30mmol / L? The mixed solution of CaCl2 and 0.25-1.50 mmol / L citric acid is sprayed and germinated every 1-4 hours for 1-3 minutes, the spray flow rate is 50-200 mL / min, and the germination is 2-4 days. The invention has simple operation, can enhance the crispness and tenderness of bean sprouts, and the degradation rate of phytic acid can reach 15-60%.

Description

1. Technical field [0001] The invention relates to a production technology of low-phytic acid bean sprouts, which belongs to the technical field of food production. 2. Background technology [0002] Bean grains are rich in protein, fat, carbohydrates, and some functional substances, but the phytic acid present in beans reduces the nutritional value. Phytic acid is the main storage form of phosphorus in plant seeds, and it is difficult to be absorbed and utilized by monogastric animals; phytic acid is also combined with metal ions such as calcium, potassium, magnesium, iron, and zinc in a covalently bonded form, thereby reducing phosphorus and The availability of these metal ions; phytic acid forms complexes with proteins, thereby reducing their digestibility. [0003] When legumes germinate, the reduction of phytic acid content is mainly caused by the activation of phytase activity by humid environment, and the phytase activity is affected by many factors. Raw materials fo...
