Example Embodiment

[0022] Example 1:

[0023] 1. Soak soybeans in acetic acid aqueous solution of 0.1g / L chitosan containing 50mM glutamic acid with a mass concentration of 0.1g / L (addition of acetic acid per liter of solution is 0.1mL) at room temperature for 8h, wash twice with water, and then place at 25℃, 80 Sprout in a germination box with% humidity, and when the sprout is 30 mm long, take it out as a germinated soybean material rich in soybean isoflavones and r-aminobutyric acid.

[0024] 2. Weigh the germinated soybeans into a soybean milk machine, add 2 times the mass of deionized water for crushing and beating, extract the soluble components, filter with a 100-mesh sieve, and freeze-dry the filtrate at -52°C to obtain germinated soybean powder. The germinated soybean meal was subjected to double enzymatic hydrolysis (flavor protease: alkaline protease = 7:3 (w / w)). Enzymatic hydrolysis conditions are: preheat the germinated soybean meal in water at 90°C for 10 minutes to dissolve it into an...

[0035] Example 2

[0036] Soak the soybeans in acetic acid aqueous solution containing 50mM glutamic acid with a mass concentration of 0.3g / L (the amount of acetic acid added per liter of the solution is 0.3mL) for 7h at room temperature, wash twice with water, and then place at 25℃, 90% humidity Sprout in the germination box, and when the shoot length is 35mm, take it out as a raw material for germinated soybeans rich in soy isoflavones and r-aminobutyric acid. Then, according to step 2 in Example 1, a crude extract of germinated soybean peptide was prepared.

[0037] Weigh 12 g of the above core material (crude germinated soybean peptide extract), add 300 g of deionized water, and stir to dissolve at 60°C. Take 0.6 mL of food grade Tween-60 and add it to the core material solution, and emulsify for 5 minutes under high-speed shearing and stirring at a rotation speed of 12,500 rpm / min to form a uniform core material (germinated soybean peptide crude extract) emulsion. Weigh 31.2...

Abstract

The invention discloses sprouted soy peptide crude extract microcapsule powder and a preparation method thereof. By adopting a biological enzymolysis technique and a complex coacervation spray drying micro-encapsulation technique, taking sprouted soy beans as raw materials and using the hydrolytic action of proteases to process soy proteins of the sprouted soy beans into soy peptides, sprouted soy peptide crude extract is prepared and then is subject to treatment such as complex coacervation, emulsification, homogenization, spray drying and the like. Therefore, the invention provides the preparation method of the sprouted soy peptide crude extract microcapsule powder. The prepared microcapsule powder has high stability and good fluidity and the activity of functional components in the product can be protected.

Description

technical field [0001] The invention relates to a microcapsule powder in the field of food technology and a preparation method thereof, in particular to a germinated soybean peptide crude extract microcapsule powder and a preparation method thereof. Background technique [0002] In recent years, some studies have found that after beans are properly germinated, their nutritional components are changed, and a unique flavor and taste can be formed. After soybean seeds germinate, proteins are decomposed into amino acids under the action of their own hydrolytic enzymes, while anti-nutritional factors such as phytic acid and trypsin inhibitors are degraded, and the synthesis of bioactive factors such as soybean isoflavones, vitamin C, and r-aminobutyric acid increases , so that germinated soybeans have richer nutritional value, which is more conducive to human digestion and absorption. However, the traditional cultivation process of bean sprouts often encounters problems such as ...
