Abstract

The invention relates to the technical field of food preservation and particularly relates to a longan seed essential oil preservative applied to dragon fruits and a preparation method of the longan seed essential oil preservative. The longan seed essential oil preservative provided by the invention comprises the following raw materials in parts by weight: 20-40 parts of longan seed essential oil, 3-7 parts of dragon fruit stem extract, 1-5 parts of gelatin powder, 5-10 parts of aloe extract and 5-10 parts of frangipani extract. The longan seed essential oil mainly plays a role in preservation in the longan seed essential oil preservative, and the longan seed essential oil contains multiple effective components such as oleic acid, has the effects of scavenging free radicals in organisms, inhibiting bacterial growth and effectively achieving oxidation resistance, and can promote fruit preservation. By compounding the longan seed essential oil with plant source components such as the dragon fruit stem extract, the gelatin powder, the aloe extract and the frangipani extract, a preservative film can be formed on the surface of a dragon fruit, so that safe and nontoxic dragon fruit preservation can be realized, and the preservation time of the dragon fruit can be prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of food preservation, in particular to a longan kernel essential oil preservative applied to pitaya and a preparation method thereof. 【Background technique】 [0002] Dragon fruit (Latin scientific name: Hylocereus undulatus Britt), a plant of the genus Cactus, is also known as red dragon fruit, dragon fruit, fairy honey fruit, and jade dragon fruit. Dragon fruit is rich in nutrition and has unique functions. It contains plant-based albumin and anthocyanins, which are rare in common plants, and is rich in vitamins and water-soluble dietary fiber. In the natural state, the fruit matures in summer and autumn, and is sweet and juicy. Because red dragon fruit is easy to grow, high yield, high price and outstanding economic benefits, it is currently a fruit tree widely promoted and planted in Guangxi. Higher content will cause dragon fruit to be easily attacked by external bacteria and cause rot and deteriorati...
