The present disclosure provides compositions and methods of recovering a policosanol or a sterol from a mixture comprising one or more fatty alcohols, aldehydes, fatty acids, and / or sterols. The mixture may be, for example, a lipid extract obtained from industrial fermentation processes (e.g., filter cake, distillate residue). The policosanol and / or sterol fraction recovered may be enriched in certain fatty alcohols (e.g., 1-octacosanol, 1-triacontanol, and / or 1-dotriacontanol), or enriched in certain sterols (e.g., ergosterol, campesterol, stigmasterol, and / or β-sitosterol). These bioactive molecules may be useful in the treatment or prevention of various metabolic conditions (e.g., obesity, dyslipidemia, cardiovascular conditions, and other chronic metabolic diseases).

The invention belongs to the cross field of functional food processing and diabetes adjuvant therapy, and discloses a high-activity sugarcane hypoglycemic beverage and a preparation method of a prebiotic additive thereof. The method comprises the steps of sugarcane raw material separation, supercritical CO2 extraction of active components of sugarcane peel (the temperature is 35-45 DEG C, the pressure is 20-30 MPa, and the time is 60 + / -10 min), enzymolysis synergistic squeezing (compound enzymes comprise glucose isomerase, cellulase and pectinase), graded membrane separation desugaring and active compounding (the sugar degree is adjusted to 6.0 + / -0.5 degree Bx) and the like, and the blood glucose reducing beverage containing 15-18 mg / L of octacosanol, 105-120 mg / L of sugarcane polyphenol and 5.5-6.5 degree Bx is prepared. Meanwhile, the membrane separation trapped fluid is processed into the prebiotic additive of which the water-soluble dietary fiber is greater than or equal to 65% and the prebiotic activity index is greater than or equal to 2.8. The invention solves the problems of active ingredient loss, inaccurate sugar degree regulation and control and the like in the prior art, and is suitable for the development of functional foods for adjuvant therapy of diabetes mellitus.

This invention discloses a formula and preparation method of a liver-protecting, lipid-lowering, and hangover-relieving nutritional tablet based on pecinosyl glycosides. The formula comprises 5-30 parts of rice bran fatty alkanol, with octacosanol as the main component; 10-50 parts of Gastrodia elata water extract, with a gastrodin content of not less than 0.5%; 20-80 parts of a natural product water extract rich in dihydromyricetin, with a dihydromyricetin content of not less than 5%; 10-50 parts of Prunus mume water extract; 1-10 parts of taurine; and 1-5 parts of B vitamins, with B1, B2, and B6 as the main components in a 1:1:1 mass ratio. This invention uses pecinosyl glycosides as the core, combining medicinal and edible raw materials with new food ingredients, following scientific compounding principles. The active ingredients work synergistically to achieve multiple effects, including improving energy metabolism, lowering blood lipids, and protecting the liver and relieving hangovers. The effects are superior to those of single-component formulations, and it can specifically address various metabolic sub-health issues in modern populations.

The invention relates to a synergistically refined composition, comprising the following components: flavonoids, octacosanol, curcumin, partially hydrolyzed guar gum, solubilizer, promoter, stabilizer, compound shading auxiliary material, functional sugar alcohol, preservative and distilled water; according to the characteristics of each extract, cross-linking and integration are carried out to introduce nano-level ultra-high purity extracts into the composition, while maintaining the physiological activities of octacosanol and curcumin, the water solubility and stability thereof are increased, the absorption rate and bioavailability in the body are increased, and premature elimination by the body is avoided, and the effective dose in the blood is ensured to be maintained; according to actual needs, by adjusting the changes in the components, the composition is used in the fields of weight loss, disease prevention, astronauts and development of military high-energy, special function and new generation sports medicine compositions; the preparation method is adjusted to obtain a liquid or solid composition.

The invention discloses an application of octacosanol in preservation of apple fruits. The invention discloses application of octacosanol in preservation of apple fruits, the application range of octacosanol is expanded, octacosanol is long-chain fatty alcohol naturally existing in plant epidermis wax, toxicity to human bodies and the environment is extremely low, and the octacosanol can be used in a reasonable concentration range, so that the octacosanol has a good preservation effect on apple fruits. The apple preservative has no adverse effect on apple fruit preservation and human health, meets the safety standard of food contact substances, is easy to degrade in the natural environment, does not cause environmental pollution, and is more environment-friendly compared with a traditional chemical preservative; the octacosanol aqueous solution is used for treating the apple fruits, so that the reduction of fruit hardness and cellulose content in the fruit storage period can be remarkably inhibited, and the conversion of original pectin to soluble pectin is inhibited; meanwhile, the activity of superoxide dismutase and catalase of the fruits is improved, and the oxidation resistance of the fruits is enhanced.

The invention relates to a preparation method of an anti-hypoxia stress mixed fatty alkanol aquatic feed additive, and belongs to the technical field of aquatic feed additives.
