Embodiment 1

[0021] Embodiment 1: the preparation of microcapsule C

[0022] Dissolve 5.7g of β-cyclodextrin in 57ml of deionized water and stir at 70°C for 1h. Mix 1ml of eugenol and 1ml of hexanal (dissolved in 2ml of absolute ethanol), then slowly add the above solution, stir at 50°C for 3h, then cool and filter with suction, and place the filtrate at 60°C constant temperature drying oven, overnight. The obtained white solid is microcapsule C, which is stored at room temperature.

Embodiment 2

[0023] Embodiment 2: the preparation of microcapsule D

[0024] Dissolve 5.7g of β-cyclodextrin in 57ml of deionized water and stir at 70°C for 1h. Mix 1.9ml of eugenol and 0.1ml of hexanal (dissolved in 2ml of absolute ethanol), then slowly add the above solution, stir at 50°C for 3h, then cool and filter with suction, and place the filtrate in 60 ℃ constant temperature drying oven, overnight. The obtained white solid is microcapsule D, which is stored at room temperature.

Abstract

The invention discloses a microcapsule for food preservation and application thereof. The microcapsule comprises a core material and a wall material and is prepared by adopting an inclusion method. The core material comprises eugenol and hexanal with the volume ratio being 1-19:1. The microcapsule has a high-efficiency bactericidal effect for peronophythora litchii, penicillium italicum wehmer, fusarium oxysporum and colletotrichum gloeosporioides, has the characteristics of wide bacteriocidal spectrum, low use amount, good bacteriocidal effect, no easy generation of drug resistance and the like, and has the advantages of no toxicity, safety, no pollution to the environment and the like since both the eugenol and the hexanal are food additives, so that the microcapsule can be applied to anti-corrosive preservation of foods, especially picked fruits and vegetables, as a nuisanceless green preservative.

Description

Technical field: [0001] The invention belongs to the field of food preservation, and in particular relates to a food preservation microcapsule and an application thereof. Background technique: [0002] With the improvement of people's living standards, people have attracted widespread attention to the safety of food preservatives. Food preservatives are required to have the characteristics of non-toxicity, less residue, high efficiency, and harmlessness to the human body. Therefore, the development of pollution-free green preservatives is a research trend in the field of fresh-keeping. [0003] Eugenol (Eugenol) is an edible spice that is allowed to be used in my country (standard number: QB 1509-1992), and it has good control effects on Staphylococcus aureus, Salmonella typhimurium, Aspergillus flavus, etc. (Appl Biochem Biotechnol. 2013, 170(6): 1379-88). In the United States, Hexanal is a food additive (EAFUS: A Food Additive Database. 2013, U.S. Food and Drug Administra...
