Description

High-dietary-fiber germinated quinoa biscuit and preparation method thereof
Technical Field
The invention relates to the technical field of food processing, in particular to a high-dietary-fiber germinated quinoa biscuit and a preparation method thereof.
Background
Quinoa is rich in starch, protein, essential amino acids and mineral elements, and is rich in various functional compounds, such as polyphenol, isoflavone, choline, phytosterol, phytic acid, saponin, etc., and also contains a special substance phytoecdysone (ecdysone steroid 20-hydroxyecdysone), and has effects of regulating immunity, controlling glucose homeostasis and preventing diet-induced obesity of mice.
The quinoa germinates under certain conditions, macromolecular substances such as protein and starch are degraded to different degrees, the content of free essential amino acids is increased, more importantly, various enzymes in the quinoa are activated in the germination process, and glutamic acid is catalytically converted into gamma-aminobutyric acid (GABA) through glutamic acid decarboxylase. GABA has important function in improving stress and mood disorder, and ingestion of GABA can improve the activity of glucosyl phospholipase, thereby promoting energy metabolism of brain, increasing cerebral blood flow and oxygen supply, improving nerve function, further achieving the effects of improving sleep and irritability symptoms and the like, and also having the biological effects of relieving blood vessels and lowering blood pressure.
However, at present, common ungerminated quinoa is adopted in biscuits taking quinoa as a raw material, wherein the GABA content is not high; in common high dietary fiber biscuits at home and abroad, the dietary fiber sources mainly comprise coarse cereals or raw materials added with dietary fibers, the physiological action of dietary fibers of different sources and different types is greatly different, but most of the high dietary fiber biscuits at present only have 2-3 types of added dietary fibers, and the types and the effects of the dietary fibers are single. Chinese patent application CN109845789A discloses a weight-reducing meal-replacing red yeast rice high-protein dietary fiber biscuit and a preparation method thereof, ungerminated quinoa is added into the biscuit, the added dietary fiber is single in type, the baking temperature is high (baking is carried out at 210-240 ℃ for 12-16 minutes), vitamins and dietary fibers in raw materials are easily damaged, and the nutritional value is reduced.
In addition, most of the existing high dietary fiber biscuits are rough to eat, even have the feeling of being pricked into the throat, the taste is not good, in order to improve the taste, hydrogenated vegetable oil containing a large amount of saturated fat or animal oil such as butter, lard, beef tallow and the like is usually used for processing the biscuits in the preparation process, the using amount of the oil reaches 40% -50%, the taste is crisp, but the high oil content is caused, and the health is not facilitated.
In addition, although some dietary fibers are added during the preparation of biscuits, the added dietary fibers weaken the network structure of the gluten protein, so that the rheological property of the dough is deteriorated, the stickiness of the dough is reduced, the biscuits are easy to crack and break during baking processing, storage and transportation, and the processed biscuits have uneven surfaces, rough mouths and reduced sensory quality.
Therefore, the high-dietary-fiber germinated quinoa biscuit and the preparation method thereof are problems to be solved urgently by the technical personnel in the field.
