Process for preparing honeycomb polyphenol extractive microcapsule by adopting spray drying method

Abstract

The invention discloses a process for preparing a honeycomb polyphenol extractive microcapsule by adopting a spray drying method and belongs to the field of microcapsule preparation. The process comprises the steps: sieving honeycomb powder by a 40-mesh sieve, mixing the honeycomb powder passing through the 40-mesh sieve and deionized water with the liquid-material ratio being 20-40 / 1(w / v), fully stirring by adopting a magnetic water-bath stirring bar, extracting 6-8min at the temperature being 30-50 DEG C so as to obtain a honeycomb water extract liquid, concentrating the honeycomb water extract liquid to obtain a product of which the content of solid contents is more than 10%, adding 280-350ml of the honeycomb water extract liquid in maltodextrin in which the content of a solid propolis water extractive is within 65-75% and Arabic gum in which the content of a solid propolis water extractive is within 3-5%, blending to obtain a mixed solution, filtering the mixed solution to obtain filter liquor, and carrying out spray drying on the filter liquor under a condition that the feeding amount of a peristaltic pump is 300-400ml / h so as to obtain the honeycomb polyphenol extractive microcapsule. The honeycomb polyphenol extractive microcapsule prepared by adopting the process is spherical, smooth in appearance, free from cracks, capable of increasing the bioavailability of honeycomb polyphenol, and high in heat stability; the embedding rate can be up to 46.6%.

Description

technical field [0001] The invention relates to the field of preparation technology of microcapsules, in particular to a preparation technology of honeycomb polyphenol microcapsules. Background technique [0002] The honeycomb is the honeycomb, which is the place where the bees live, reproduce and store food. It is built by processing the beeswax secreted by the wax glands of the worker bees. Honeycomb is not only rich in nutrition, non-toxic, but also has antibacterial, anti-inflammatory, and tumor-inhibiting effects. Therefore, honeycomb will have a wide application prospect in the food industry. The medicinal value of honeycomb is also very high, and fresh and clean honeycomb is often used to treat rhinitis. Old honeycomb has curative effect on diseases such as hepatitis, rhinitis and rheumatoid arthritis. Studies have shown that honeycomb preparations can promote the body's cellular immune function. [0003] Polyphenol is the general term for polyhydric phenolic compo...

AI Technical Summary

Problems solved by technology

[0005] At present, there are studies on the use of ultrasonic-assisted extraction to extract polyphenolic flavonoids in honeycombs, but polyphenols have phenolic hydroxyl groups and are easily oxidized, which is generally easy to occur when exposed to air non-enzymatic browning

The current research on microcapsules includes the microencapsulation of seabuckthorn oil, Eucommia leaf water extract, kiwi fruit polyphenols, etc., but there is no research on propolis polyphenol microcapsules
