This invention belongs to the field of pharmaceutical technology, specifically relating to an alginate oligosaccharide, its preparation method, and its applications. Using brown algae as raw material, the invention first removes impurities from the algae, then extracts it through subcritical acid water, followed by neutralization, decolorization, heavy metal removal, membrane ultrafiltration / nanofiltration purification, and spray drying to obtain high-purity saturated alginate oligosaccharides with a specific degree of polymerization distribution. These alginate oligosaccharides can increase butyrate production by intestinal flora and exert a laxative effect. The alginate oligosaccharide and its preparation method provided by this invention directly use brown algae as raw material, overcoming the drawbacks of traditional methods that first prepare alginate and then hydrolyze it to prepare alginate oligosaccharides, greatly shortening the process steps and improving production efficiency. The alginate oligosaccharides provided by this invention have high purity and broad application potential in the preparation of intestinal health drugs, health products, or dietary supplements.

This invention discloses a regulatory dietary supplement containing mulberry leaf γ-aminobutyric acid (GABA) and polyphenols, and its preparation method, belonging to the field of dietary food technology. It consists of the following raw materials in parts by weight: 15-30 parts mulberry leaf extract, 40-60 parts cereal base, 10-20 parts plant protein powder, 5-15 parts dietary fiber, 2-8 parts mineral fortifier, and 1-5 parts natural sweetener; the mulberry leaf extract contains ≥8 mg / g GABA and ≥15 mg / g total polyphenols; the mineral fortifier is potassium salt, with a sodium content ≤120 mg / 100g and a potassium content ≥500 mg / 100g. The preparation method includes: compound enzymatic hydrolysis-ultrasonic synergistic extraction of mulberry leaf extract, low-temperature drying and pulverization of barley grass powder, premixing and masking the flavor of the mineral fortifier and protein powder, and total granulation. This invention utilizes the synergistic effect of GABA and polyphenols on the neurovascular dual pathway, providing dual functions of soothing emotions and assisting in blood pressure regulation. It is also low in sodium and high in potassium, with an excellent taste, making it suitable for daily dietary supplementation and functional meal replacement for people who value a healthy lifestyle and those with special nutritional needs.

This invention relates to the field of biomedical technology, specifically to the application of L-methionine in the preparation of drugs for preventing and treating cognitive impairment in offspring. According to this invention, early intervention through maternal dietary supplementation with L-methionine following heavy metal exposure can provide long-term and comprehensive improvement in offspring's cognitive recognition, spatial memory, and adventurous exploration behaviors, without significantly affecting maternal cognitive behavior. This invention is the first to clearly define pregnancy as a critical window for L-methionine intervention in offspring cognitive impairment caused by heavy metal exposure, providing a safe, feasible, and scientifically based nutritional intervention strategy, and offering a new approach for related public health prevention and product development.
