According to the infant amino acid nutritional rice flour and the preparation method thereof, four proteases including flavourzyme, pepsase, papain and bromelain are provided, and the proteases have very high hydrolytic activity and can fully hydrolyze protein in rice and whole milk powder to form various amino acids and polypeptide fragments, so that the nutritional rice flour is prepared; the rice flour is beneficial to digestion and absorption of infants, does not cause protein allergy, also improves the utilization rate of protein, and also can increase the flavor of the rice flour. Through detection, all 16 amino acids listed in GB5009.124-2016 Measurement of Amino Acid In Food National Standard for Food Safety can be detected in the infant amino acid nutritional rice flour prepared by the method disclosed by the invention; the amino acids are respectively alanine, valine, leucine, isoleucine, phenylalanine, proline, glycine, serine, threonine, tyrosine, methionine, lysine, arginine, histidine, aspartic acid and glutamic acid, the content of the glutamic acid is the highest, and the total amount of the amino acids can reach 10.5-11.2 g / 100g.

The invention discloses an application of ultrasound and teuvincenone H diterpenoid treatment in reduction of tenebrio molitor protein allergy, the tenebrio molitor protein is treated by ultrasound and teuvincenone H diterpenoid, so that the binding capacity of the tenebrio molitor protein and immunoglobulin E (IgE) can be reduced, and the allergy of the tenebrio molitor protein is further reduced. The invention discloses other effects of teuvincenone H diterpene except for anti-tumor and anti-inflammatory effects for the first time, and the method has the advantages of simple process steps, short treatment time, low temperature, high efficiency, rapidness and environmental friendliness, is beneficial to wide application of related technologies in the field of food industry, and provides a brand new scheme for developing safe and high-quality insect protein food.

This invention provides a synbiotic for regulating protein allergy, an infant amino acid formula powder, and its preparation method, belonging to the field of milk powder technology. A synbiotic for regulating protein allergy comprises the following components in parts by weight: 10-30 parts of galactooligosaccharides, 1-3 parts of fructooligosaccharides, 5-15 parts of 2'-fucosylated lactose, 1-3 parts of lactose-N-neotetrasaccharide, 1-2 parts of sodium 3'-sialotyl-lactose, and 0.1-5 parts of Bifidobacterium longum subsp. infantis M-63. The synbiotic components work synergistically to deeply mimic the mechanisms of action of breast milk in building intestinal microecology, regulating immune function, and promoting digestive comfort. Combined with amino acids, nucleotides, and other nutrients, this formula is formulated into an infant amino acid formula powder, which can effectively reduce allergy symptoms and reactions, providing a scientific nutritional solution that closely approximates the physiological benefits of breast milk for allergic infants who cannot be breastfed.

The present invention belongs to the technical field of probiotics and their application, and specifically relates to a strain of Lactobacillus delbrueckii subsp. lactis MB4 and its application in the preparation of hypoglycemic and sleep-aiding food and medicine. The present invention separates and purifies a strain of Lactobacillus delbrueckii subsp. lactis MB4 from the feces of a healthy adult in Guangdong, China, and the strain can produce and secrete γ-aminobutyric acid, and can inhibit the activity of α-glucosidase, and has the functions of promoting the digestion and absorption of protein food, improving protein allergy, anti-depression and improving sleep, hypoglycemic and weight loss, etc., and can be used in the fields of hypoglycemic and sleep-aiding, for example, it can be made into hypoglycemic and sleep-aiding medicines, and has important application value and economic value.

The invention discloses a protein allergen marker in an andrographis paniculata extract and a detection method of the protein allergen marker in the andrographis paniculata extract, which are used for detecting the level of trace protein in the andrographis paniculata extract and related injections thereof by adopting an analysis method of ultrafiltration enrichment and proteomics combined with liquid chromatography-mass spectrometry. The invention provides a new method for evaluating the sensitizing substances of the andrographis paniculata extract and related injections thereof, and has important application value.

The application relates to the field of cosmetics, and specifically provides a composition for improving skin aging and application and method thereof, the composition comprising cyclin-dependent kinase 1, glutathione peroxidase 5 and cellular retinoic acid binding protein 1. The composition of the application can synergistically regulate cell proliferation, antioxidation and retinoic acid metabolic pathways, significantly improve skin photoaging, and improve bioavailability; the three protein molecules have a molecular weight less than 35 kDa, can efficiently penetrate the stratum corneum to reach the dermis, and can greatly improve the absorption rate of external use; the protein can be obtained through human recombinant expression, the risk of animal-derived protein allergy can be effectively reduced, the protein has high safety and industrialization potential, and has wide application value.

The present invention belongs to the technical field of probiotics and their applications, and particularly relates to a Lactiplantibacillus plantarum SM1 and its applications in the preparation of foods and drugs for gastrointestinal conditioning and weight loss. In order to explore more Lactiplantibacillus plantarum with probiotic functions, the present invention isolated and purified a strain of Lactiplantibacillus plantarum SM1 from the fecal sample of a healthy adult in Guangdong region. This strain has excellent protease activity, excellent cellulase activity, can produce and secrete glutathione, can produce and secrete γ-aminobutyric acid, can inhibit α-glucosidase activity, can inhibit xanthine oxidase activity, can inhibit renin activity, and has various functions such as promoting the digestion and absorption of protein foods and improving protein allergy; promoting the absorption of cellulose and improving constipation, etc., and has important application value and economic value in the fields of gastrointestinal conditioning and weight loss.

The present invention relates to synthetic and / or recombinant consensus allergens and to their use as allergy vaccines in particular in the treatment of peach-cypress allergy, in the form of an allergy vaccine comprising a consensus allergen and / or a nucleic acid sequence encoding such, wherein the consensus allergen comprises at least (60) amino acids and is derived from a consensus sequence of the amino acid sequences of at least five (5) protein allergens, and wherein said protein allergens share at least 20% amino acid sequence identity.
