Abstract

The invention especially relates to an ivory-shaped scented rice essential oil preservative and a preparation method thereof, belonging to the technical field of processing of preservatives. The ivory-shaped scented rice essential oil preservative is prepared from the following raw materials by weight: 30 to 45 parts of ivory-shaped scented rice essential oil, 10 to 17 parts of the extract of wasabi, 15 to 17 parts of the extract of lemon peel, 5 to 10 parts of cassava starch, 10 to 17 parts of the extract of konjac and 5 to 10 parts of sodium alginate. Through compounding of the above components, the ivory-shaped scented rice essential oil preservative provided by the invention has effectively improved fruit and vegetable preservation capability, does not leave any harmful substances and is a safe and effective ivory-shaped scented rice essential oil preservative. The invention also provides a supercritical CO2 extraction method for ivory-shaped scented rice essential oil. Precipitation of ivory-shaped scented rice essential oil components is improved via combination of the method and pretreatment.

Description

【Technical field】 [0001] The invention relates to the technical field of antistaling agent processing, in particular to an ivory fragrant rice essential oil antistaling agent and a preparation method thereof. 【Background technique】 [0002] At present, chemical agents combined with physical methods are mainly used to preserve fruits and vegetables. However, with the improvement of people's environmental and health awareness, the application of chemical agents in fruit and vegetable preservation has been and will be further reduced. Plant-derived preservatives have received increasing attention in the field of post-harvest preservation of fruits and vegetables in recent years because they do not have the environmental pollution, pesticide residues, and drug resistance caused by chemical antiseptic preservatives. Therefore, the production of a plant-derived preservative is currently the A new direction for industry research. Ivory basmati rice is rich in starch, and its essen...
