51 results about "Anethole" patented technology

Anethole (also known as anise camphor) is an organic compound that is widely used as a flavoring substance. It is a derivative of phenylpropene, a type of aromatic compound that occurs widely in nature, in essential oils. It contributes a large component of the odor and flavor of anise and fennel (both in the botanical family Apiaceae), anise myrtle (Myrtaceae), liquorice (Fabaceae), camphor, magnolia blossoms, and star anise (Illiciaceae). Closely related to anethole is its isomer estragole, abundant in tarragon (Asteraceae) and basil (Lamiaceae), that has a flavor reminiscent of anise. It is a colorless, fragrant, mildly volatile liquid. Anethole is only slightly soluble in water but exhibits high solubility in ethanol. This trait causes certain anise-flavored liqueurs to become opaque when diluted with water, the ouzo effect.

Gas-phase sustained-release mildew-resistant antistaling agent, and preparation method and application thereof

The invention discloses a gas-phase sustained-release mildew-resistant antistaling agent and a preparation method and application thereof. The gas-phase sustained-release mildew-resistant antistaling agent is prepared through complex formulation of microcapsules of four plant essential oils consisting of anethole, cinnaldehyde, citral and salicylaldehyde. Beta-cyclodextrin is used as a wall material to respectively encapsulate the four plant essential oils consisting of anethole, cinnaldehyde, citral and salicylaldehyde, so four plant essential oil microcapsules are obtained; then the four plant essential oil microcapsules are mixed in proportion and then are applied for mildew-resistance and preservation of grains or oil-bearing materials or for mildew-resistance and preservation of raw-food materials and packaged foods. The mildew-resistant antistaling agent inhibits mould through gas-phase fumigating effects of the essential oils and employs microcapsule technology for controlling of volatilization speeds of the essential oils, so a long-acting gas-phase mildew-resistant effect is realized without direct contact between the essential oils with grains, foodstuffs and the like; the mildew-resistant antistaling agent is especially applicable to antibiosis and mildew-resistance of grains, oil-bearing materials and packaged foods under the conditions of high temperature and high humidity, can suppress deterioration of quality of the grains, the oil-bearing materials and the packaged foods, is safe to human beings and livestock and is capable of effectively overcoming the problem of residual of a chemical fumigant.
