This invention provides a method for promoting robust seedling growth in Liangwang tea, relating to the field of artificial cultivation technology for Liangwang tea. The method involves treating seeds by burying them in river sand and fermented barley flour, sowing them in a seedling substrate supplemented with birch fermentation material, and irrigating them with a nutrient solution containing ingredients such as tamarind seed polysaccharides. This invention overcomes the shortcomings of existing technologies, effectively promoting seedling emergence in Liangwang tea and further enhancing root growth, achieving a high rate of robust seedlings in a shorter time.

This application discloses a method for preparing and applying a probiotic microcapsule based on the coagulation and encapsulation of tamarind protein and polysaccharides. The method includes the following steps: probiotics and tamarind protein are separately added to sterile water and mixed to obtain a bacterial suspension; the bacterial suspension is mixed with a mixed solution of sodium alginate and tamarind polysaccharides to obtain a second mixture; the second mixture is added dropwise to a calcium chloride solution and collected; the resulting precipitated capsules are mixed with a gelatin solution and stirred, then pectin is added, and stirring continues after adding pectin to obtain the probiotic microcapsules based on the coagulation and encapsulation of tamarind protein and polysaccharides; the probiotic microcapsules based on the coagulation and encapsulation of tamarind protein and polysaccharides are stored in ultra-high pressure fruit juice. The resulting capsules achieve an encapsulation rate of 89.42% for probiotics, exhibit good tolerance and timely release in simulated gastric juice at pH 1.5, and the probiotic capsules retain an activity level of 10% even after the fruit juice is stored at 4°C for 21 days. 9 CFU / g or higher.

An agent for oxidatively dyeing keratin fibers, in particular human hair, containing, in a cosmetic carrier, isatin and at least one polymer from the group consisting of xanthan gum, algin, carrageenan, cetyl hydroxyethyl cellulose, carboxymethyl cellulose, tragacanth, gum karaya, gum ghatti, agar, chitin, chitosan, gum arabic, gellan gum, guar gum, tamarind seed flour, carob gum, and the physiologically acceptable salts thereof.

The invention discloses a method for preparing high-molecular and high-transmittance tamarind polysaccharide by using a non-organic solvent. According to the method, a tamarind seed kernel extracting solution is subjected to stabilization pretreatment, a biodegradable chelating agent EDDS and an antioxidant OTA are added, and a step-by-step enzymolysis and refining process of amylase and compound protease is combined. According to the method, organic solvent residues and acid extraction degradation are avoided, and the obtained product has high molecular weight, extremely low protein residues and excellent light transmittance and has wide application prospects in the fields of cosmetics and the like.

The invention provides a small molecule peptide, which is derived from a tamarind seed, and the amino acid sequence of the small molecule peptide is selected from Val-Ser-Asp-Tyr, Asp-Gly-Ile-Asp-Phe, Ala-Lys-Asn-Val-Ser-Asp-Tyr-Leu, Tyr-Asn-Asp-Pro-His-Cys, Val-Pro-Pro-Asp, Asn-Asp-Pro-His-Cys-Gln-Tyr, and the amino acid sequence of the small molecule peptide is selected from the group consisting of Val-Ser-Asp-Tyr, Asp-Gly-Ile-Asp-Phe, Asp-Gly-Ile-Asp-Phe, starting from the sequence of tamarind seed protein, polypeptide with double biological activities of reducing blood sugar and making delicate flavor is screened from tamarind seeds through virtual enzyme digestion; the alpha-glucosidase inhibitory activity and umami characteristics of the polypeptide are further verified through molecular docking, molecular dynamics simulation, in-vitro experiments and sensory evaluation experiments, and results show that the small molecule peptide has application prospects in preparation of drugs for preventing and treating diabetes mellitus and application as a food flavor modifier.
