Problems solved by technology

The fundamental reason is that people have a variety of diets but they have limitations. Most of them are limited to refined rice and fine grains. At the same time, they consume too much high-fat substances, resulting in fat accumulation in the body, protein loss, and nutritional imbalance.

Embodiment 1

[0025] Select fresh eggs, wash to remove surface dirt, put the cleaned eggs into a solution with a concentration of 0.05% decylmethylammonium bromide, take them out after sterilizing for 15 minutes, and rinse them with clean water; break the sterilized eggs to separate the egg liquid; Filter membrane to remove eggshells and other substances, homogenize at 28°C for 2 minutes; add Ph7. Water bath in a water bath at 50°C for 20 minutes, then inactivate enzymes in a water bath at 90°C for 25 minutes, quickly sterilize at 66-70°C for 5 minutes, and undergo rotary evaporation for 10 minutes, and quickly cool to below 30°C; the inlet temperature is about 170°C, and the outlet temperature is 85- 92°C, spray drying at a rate of 400ml / h; pass the spray-dried protein powder through a 100-120 mesh sieve to obtain the required egg white protein powder; take low-temperature defatted soybean meal, grind it and adjust the water content to 12%-20%, Put it into a screw-top test tube with a stop...

Abstract

The invention belongs to the technical field of fine and deep processing of agricultural products, and in particular relates to antioxidative peptide composite coarse food grain protein powder and a preparation method thereof. The preparation method comprises the following steps: preparing protein powder, preparing catechinic acid and egg white antioxidative peptide, preparing mixed powder of coarse food grains, performing mixing and blending, performing sealing and packaging, and the like. The coarse food grain protein powder provided by the invention is fragrance of protein powder and is capable of keeping human food nutrition balance. In addition, the coarse food grain protein powder has antioxidative peptide and a tea leaf extract, namely catechinic acid. The raw material antioxidative peptide has very good bioactivity and can be easily absorbed by human bodies; the catechinic acid can accelerate oxidation of fat in bodies, and has effects of losing weight and preventing obesity; in addition, the catechinic acid and the egg white antioxidative peptide have a synergic function, so that not only is functionality of the protein powder improved, but also the protein powder is relatively balanced in nutrition. The antioxidative peptide composite coarse food grain protein powder is simple in process, low in cost and wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of intensive processing of agricultural and sideline products, and in particular relates to a compound coarse grain protein powder containing antioxidant peptides and a preparation method thereof. Background technique [0002] With the continuous development of society, people's living standards are gradually improving, and people's diet is becoming more and more abundant. Many diseases such as obesity, constipation, fatty liver and more health diseases also follow. The fundamental reason is that people have a variety of diets, but they have limitations. Most of them are limited to refined rice and fine grains. At the same time, they consume too much high-fat substances, resulting in fat accumulation in the body, protein loss, and nutritional imbalance. [0003] Protein powder is mainly composed of soy protein, whey protein, egg white protein and other proteins. It is mainly used for young children, the elde...
