Problems solved by technology

[0003] The research on the encapsulation of flavors and fragrances has been started since the 1950s, and the research in this area is still in the ascendant. Compared with the microencapsulation technology of other core materials, the encapsulation of essential oils is more difficult, mainly because : (1) Essential oils are usually a mixture of dozens or even hundreds of different components, which have different solubility in water and oil, and it is very difficult to completely embed all components in a single matrix; ( 2) Different components in essential oils have different boiling points, and the volatility of components varies greatly. Some components are still highly volatile even below 0°C, and the volatilization loss of volatile components will lead to changes in fragrance; ( 3) Many components in essential oils are sensitive to heat, light, pH, oxygen, etc., which brings difficulties to capsule preparation

Abstract

The invention relates to a sugar-vitrified essential oil capsule prepared based on an extrusion method and a preparation method thereof. Essential oil is instable in nature, high in volatility, poor in water solubility and easy to deteriorate under high-temperature conditions. The preparation method comprises the following steps: preparing soya bean lecithin, water and essential oil into a pasty emulsion; mixing sucrose, modified starch and maltodextrin at a high speed, adding the emulsion, mixing according to a dry method, feeding into an extruder through a screw feeder, and extruding to prepare the essential oil capsule. The capsule prepared by the invention has a more compact and stable structure; the capsule hermetically packaged in a moisture-proof material can be stored for a long time under room temperature conditions; and the stability is greatly improved, no antioxidant needs to be used, and the capsule has a certain slow release function in application.

Description

technical field [0001] The invention relates to an essential oil capsule, in particular to a sugar vitrified essential oil capsule prepared based on an extrusion method and a method thereof. Background technique [0002] Sugar vitrification technology is a low-temperature encapsulation technology, so it is suitable for the embedding of heat-sensitive substances. Essential oil is a kind of volatile essential oil extracted from spices, also known as aromatic oil, which is a large category of natural spices. Generally, the tissues or secretions of different parts of aromatic plants are used as raw materials, and are processed by cold grinding, extraction and pressing. , steam distillation and other methods to extract, its composition is a mixture of aliphatic, alicyclic, terpene and so on. Essential oils have a unique aroma and strong antiseptic and bactericidal properties, but their properties are not stable enough, and they are highly volatile under general conditions, resu...
