The product is suitable for industrial production, the content of SECO in the product can reach 150-400 mg/100 g, and the product is a health food safe to eat.
Description
Technical Field
The invention relates to a flax seedling whole meal rich in secoisolariciresinol SECO and a production method thereof, belonging to the technical field of food processing.
Background
The germination is an important means for improving the nutritive value and functional property of plant seeds in a harmless and low-cost manner. After the grains absorb water and germinate, a plurality of physiological metabolism changes occur, and simultaneously complicated biochemical metabolism is accompanied, so that the nutritional ingredients of the grains are improved, the original harmful substances or anti-nutritional substances are reduced or eliminated, and functional active ingredients are enriched. After the flax seeds are germinated, the cyanide content is reduced, the contents of amino acid, vitamin C, mineral substances, lignan, flavone and other polyphenols are increased, and the physiological effect is enhanced. The main existing form of lignan in flax seeds is Secoisolariciresinol Diglucoside (SDG), the lignan also needs to be converted into an intermediate product Secoisolariciresinol (SECO) by intestinal bacteria to be absorbed and utilized by human bodies, and the SDG can be partially and directly converted into an aglycone form-SECO in the process of sprouting.
At present, researches on flax lignans at home and abroad mostly focus on extraction and purification processes, generally, cakes obtained after flax oil extraction or husked shell-rich portions are taken as raw materials, lignans are obtained through enzymolysis or acid-base hydrolysis, and the extraction process is complex, so that the cost of the lignans is high. The method for enriching the lignans by utilizing the characteristics of the growth and development of the plants is simple and easy, greatly reduces the production cost, is safe and reliable, and is convenient to eat. Currently, flax sprouts have been incorporated by the Ministry of agriculture into the green food sprouts category of vegetables, but the related studies have been relatively late. The patent (publication No. CN 110199613A, published 2019, 9 and 6) discloses a method for cultivating high-calcium nutritional flax sprouts and a special seed soaking method thereof, the patent (publication No. CN 110199614A, published 2019, 9 and 6) discloses a method for cultivating selenium-rich nutritional flax sprouts, the patent (publication No. CN 110352657A, published 2019, 10 and 22), discloses a method for cultivating zinc-rich nutritional flax sprouts, belongs to the agricultural field, only aims at specific minerals, and is not mentioned with SECO; the patent (publication No. CN 110463523A, published 2019, 11 and 19) discloses a cultivation method for improving lignan accumulation of flax sprouts, which belongs to the technical field of flax sprout vegetable cultivation, only flax sprouts with high SDG content are cultivated, and the flax sprouts are not directionally converted into SECO; the patent (publication No. CN 104544350A, published 2015 4-29) discloses a production method of flax seed bud powder, relating to the technical field of flax processing, wherein flax seed buds are obtained by removing dormancy, flax seed bud powder is obtained by enzyme deactivation and drying, and SECO is enriched by utilizing the characteristics of the growth and development of plants without adopting a certain means.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide SECO-rich whole flax seedling powder and a production method thereof. The product is rich in beneficial components such as amino acids, vitamins, minerals, SECO and the like, and the whole seedling is crushed and rich in dietary fiber, so that the health-care function of the whole flax seedling powder is greatly improved.
In order to solve the technical problems, the invention adopts the following technical scheme: the method comprises the following steps of immersing flax seeds in hydrogen-rich water at a certain temperature, spraying and germinating by using a mixed aqueous solution of NaCl and gamma-polyglutamic acid to enrich SECO in the flax seedlings, carrying out vacuum freeze drying and supersonic airflow crushing, sterilizing and packaging to obtain the flax seed, and specifically comprises the following steps:
(1) spray germination
A. Selecting raw materials: selecting brown flax or golden flax with full grains, no plant diseases and insect pests and a germination rate of more than 95 percent as a raw material;
