One, the technical field

The invention relates to a fruit, vegetable and grain germ nutrition powder and a production method thereof, belonging to the technical field of deep processing of food.

Second, technical background

The germination treatment can improve the nutrition and the edible quality of the grain seeds. During the germination process of the grain seeds, a large amount of zymogen in the grain seeds is activated and released, and simultaneously, new enzyme is formed, so that macromolecular substances such as starch, protein and the like in the seeds are degraded to generate small molecular substances which are easy to digest and absorb by human bodies, the absorbable nutrient components are increased, the biological value is improved, the viscosity is reduced, the mouthfeel is improved, various physiological active components such as glutathione, vitamins, antioxidant substances and the like in the grains are enriched, and particularly, the content of gamma-aminobutyric acid (GABA) and phenolic substances is obviously increased when the seeds germinate. Researches show that GABA has health care functions of regulating blood pressure, calming nerves, helping sleep, improving brain functions, promoting memory, regulating liver and kidney and the like. Along with the increase of age and mental stress, the GABA content in the human body is reduced, and the supplement of GABA from the diet is more important, so that the health of the human body is promoted. The phenolic substances are secondary metabolites containing active phenolic hydroxyl, mainly comprise phenolic acid, flavonoid and anthocyanin substances, and have physiological effects of resisting oxidation, resisting cancer, resisting aging and the like. The content of the phenolic substances in mature cereal grains is 0.7-18.0 mg GAE/g DW (GAE is gallic acid equivalent), the phenolic substances have two forms of free and combined forms, and the phenolic substances mostly exist in a combined state in a cortex layer, wherein the former is mainly a flavonoid substance, and the latter is mainly a phenolic acid substance. Phenolic acid is the main phenolic substance in cereal grains, the content of GAE/g DW in mature grains is only 0.5-3.5 mg, and the phenolic acid exists in the cortex layer in a combined state, so the bioavailability is low. When the seeds germinate, the combined phenolic acid is partially hydrolyzed into free phenolic substances, and new phenolic substances are further synthesized, so that the content of available functional components is increased. The food produced by taking the sprouted grain as the main raw material has the nutritional value and the health care function related to the above.

The patent (publication No. CN102987199A, published in 2013, 3 and 27) discloses 'fruit and vegetable nutrition powder', the patent (publication No. CN104824562A, published in 2015, 8 and 12), discloses 'fruit and vegetable and grain nutrition powder', and the two patents both disclose mixed nutrition powder of fruits, vegetables and grains. Therefore, the fruit, vegetable and functional germ grain are compounded, so that the absorptivity of nutrient substances in the grain powder can be greatly improved, the taste is improved, and the nutrition is balanced; the protein and the carbohydrate are more easily digested and absorbed by human bodies after being extruded and puffed, and the digestibility is obviously improved; the product prepared by ultrafine grinding also has the characteristics of no caking and good reconstitution property.

Third, the invention

The technical problem is as follows:

the invention aims to provide fruit, vegetable and grain germ nutrition powder and a production method thereof, which solve the technical problems of unbalanced nutritional ingredients of grains, poor edibility and the like. Meanwhile, the amino acid proportion can be balanced by compounding the sprouted grains with the fruits and vegetables, the nutritional value and the edible quality of the product are improved, and health-care components such as GABA, phenolic substances, dietary fibers and the like can be enriched.
