The application belongs to the technical field of daily chemicals, and particularly relates to a long-acting hair quality repairing composition containing silk fibroin peptides and application thereof. The application discloses a long-acting hair quality repairing composition containing silk fibroin peptides, which comprises a silk fermentation repairing liquid, silk fibroin peptides and a silk fibroin surfactant. The three components can synergistically promote the combing performance, anti-static performance and tensile performance of the composition. The silk fermentation repairing liquid is prepared by inoculating Saccharomyces cerevisiae and Rhodotorula glutinis in a fermentation medium containing silk glue proteins, then carrying out mixed fermentation, and finally carrying out enzymatic hydrolysis. The silk fermentation repairing liquid can effectively improve the damage problems of dry, rough and broken hair. The long-acting hair quality repairing composition containing silk fibroin peptides can be applied to the preparation of hair care products such as hair conditioner, shampoo, hair mask and hair care essential oil. The long-acting hair quality repairing composition containing silk fibroin peptides is safe and non-irritating, can realize long-acting and multi-dimensional repair of damaged hair quality, and has the effects of softness, gloss and repair.

The invention belongs to the technical field of daily chemicals, and particularly relates to a long-acting hair quality repairing composition containing silk protein peptide and application of the long-acting hair quality repairing composition.

The invention discloses a method for producing an active rhBMP9 bone repair material based on a double-transgene bombyx mori silk gland biosynthesis system as well as a product and application of the active rhBMP9 bone repair material, and realizes cooperative expression of complex precursor protein Pro-mhBMP9 and precursor protein invertase hFurin in bombyx mori posterior silk glands. An hBMP9 / hFurin double-gene biosynthesis system capable of completing precursor protein shearing, maturation and functionalized silk material synthesis in vivo is established, the rhBMP9 / CaP / Sericin composite scaffold is further constructed by extracting silk protein of double-gene transformation bombyx mori, and the rhBMP9 / CaP / Sericin composite scaffold shows excellent bone repair and angiogenesis capacities in both the cell level and the animal level, and can be used for preparing a bone repair material. And a solid experimental and theoretical basis is provided for a functional protein-material-tissue regeneration integrated strategy based on a silk gland biosynthesis system.

The invention provides an enterokinase light chain recombinant protein and application and a method for efficient soluble expression of a recombinant enterokinase light chain, the enterokinase light chain recombinant protein is composed of more than two fusion proteins AgSg or mutants thereof and an enterokinase light chain or mutants thereof, the amino acid sequence of the fusion proteins AgSg is shown as SEQ ID NO.3, and the amino acid sequence of the fusion proteins AgSg is shown as SEQ ID NO.3. The amino acid sequence of the enterokinase light chain is as shown in SEQ ID NO. 1; according to the enterokinase light chain recombinant protein, a specific amount of fusion protein AgSg derived from the N end of spider silk sericin is fused with an enterokinase light chain or a mutant thereof in a series connection manner, so that the expression quantity of the enterokinase light chain or / and the mutant can be remarkably improved, and the enterokinase light chain or / and the mutant can be expressed in a soluble form; the defects that a traditional escherichia coli system is low in expression quantity and expression and purification are difficult in an inclusion body form are overcome, and the method can be applied to production of high-efficiency soluble enterokinase light chains.

The invention provides a compound emulsifier based on plukenetia volubilis linneo albumin as well as a preparation method and application thereof, and relates to the field of foods. The method comprises the following steps: respectively preparing a plukenetia volubilis linneo albumin dispersion liquid, a polyphenol solution and a chitosan solution; mixing the plukenetia volubilis linneo albumin dispersion liquid with a polyphenol solution, adding laccase to carry out enzymatic cross-linking reaction, dialyzing a reaction product, and freeze-drying to obtain a binary compound; dissolving the binary compound, mixing the dissolved binary compound with a chitosan solution, adding laccase to carry out enzymatic cross-linking reaction, and dialyzing and freeze-drying a reaction product to obtain the compound emulsifier based on the sacha inchi albumin. Through the synergistic effect of the components, the stability, oxidation resistance, functionality and extrusion plasticity of a high internal phase emulsion constructed by taking the high internal phase emulsion as an emulsifier are improved, the high internal phase emulsion can be used as a core matrix of plant-based smear food, and the problems that a traditional matrix is poor in stability, single in function, poor in extrusion plasticity and the like are solved.

A modified diatomaceous earth, a modified diatomaceous earth-based Pickering emulsion, and a method for preparing the same are disclosed, relating to the field of emulsion-type cosmetics technology. The modified diatomaceous earth is diatomaceous earth modified with glycidyl ether, with a water contact angle of 90°–128°; the glycidyl ether is one or a combination of at least two of allyl glycidyl ether, diglycidyl ether, isopropyl glycidyl ether, n-butyl glycidyl ether, lipoalkyl diglycidyl ether, allyl alcohol glycidyl ether, and phenyl glycidyl ether. The emulsion comprises phases A, B, and C; phase A comprises water, glycerol, lauric acid, potassium sorbate, and modified diatomaceous earth; phase B comprises stearic acid, myristic acid, dimethyl ether, polyquaternium-7, ethanol, and butylene glycol; phase C comprises sodium hyaluronate, acetylated sodium hyaluronate, silk fibroin, hydrolyzed silk, and disodium EDTA.
