This invention discloses an oil composition with a balanced fatty acid ratio and lipid-lowering effects, and its applications. The oil composition comprises vegetable oil, probiotics, phospholipids from camellia seed cake, gelatin, and sodium alginate. It effectively reduces serum triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels while increasing high-density lipoprotein cholesterol levels, exhibiting a good lipid-lowering effect. Furthermore, when the oil composition is formulated into microcapsules, it exhibits good stability, encapsulation efficiency, and release rate. The oil composition also helps maintain the activity of probiotics, allowing for better preservation and efficacy. Based on this, this invention also provides a candy containing the oil composition, enriching the variety of products with lipid-lowering effects and promoting the development of lipid-lowering related products.

The application relates to the technical field of archaea DNA extraction, in particular to a preparation method and application of auxiliary wall-breaking nanometer magnetic beads for archaea DNA extraction. The method comprises the following steps: (1) constructing an inverse emulsion droplet microfluidic chip: washing, drying and hydrophobic modification treatment are performed on a PDMS base material to prepare a microfluidic chip; (2) preparing an inverse microemulsion system: the continuous phase and the dispersed phase are respectively pumped into the microfluidic chip at a predetermined flow rate, so that Fe 2+ and Fe 3+ undergo a coprecipitation reaction to generate Fe3O4 nanoparticles; (3) maturation crystallization; (4) demulsification separation and washing; and (5) drying to obtain auxiliary wall-breaking nanometer magnetic beads. The method has the beneficial effect of solving the problems in the prior art that the cell wall is difficult to effectively break, the DNA release rate is low, the extraction purity is poor, the repeatability is insufficient and the standardization and continuous preparation are difficult to realize when DNA extraction is performed on archaea samples in extreme environments.

The present invention relates to a functional feed and an oral delivery system for delivery of bioactive macromolecules. The oral delivery system comprises ethylenediammonium alginate which is a vehicle for delivery of macromolecular drugs.

This invention belongs to the field of food processing technology, specifically relating to an oat bran β-glucan extract, its preparation method, and its application. The preparation method involves obtaining the oat bran β-glucan extract from oat bran through multi-stage enzymatic hydrolysis. The enzymes used in the multi-stage hydrolysis sequentially include pentosanase, thermostable α-amylase, and proteinase K. This invention, under ultrasound assistance, allows pentosanase to efficiently break down cell walls first, significantly increasing the release rate of β-glucan. Subsequently, thermostable α-amylase and proteinase K precisely remove starch and protein impurities sequentially, greatly improving the purity of the product. This process route is mild, highly specific, and operates continuously, reducing impurity residue while improving extraction efficiency, providing a reliable and cost-effective solution for the large-scale preparation of high-purity, highly bioactive oat β-glucan.
