Embodiment 1

[0034] The preparation of embodiment 1 composite plant extract antifungal agent

[0035] 1. Preparation of plant extract mixture

[0036] According to the volume ratio of 3:3:2:2, take cinnamaldehyde, citral, eugenol and peppermint oil (33% L-menthol, the solvent is absolute ethanol); mix them in sequence according to the proportion from less to more 4 kinds of plant essential oils are added while stirring, and mixed evenly to make a compound plant essential oil antifungal agent.

[0037] 2. pH adjustment of compound plant extracts

[0038] Use triethanolamine to adjust the pH of the compound plant extract mixture in step 1 to 6.5-7.0 to obtain the compound plant extract.

[0039] 3. Preparation

[0040]Filter the composite plant essential oil antifungal agent with a 0.22 μm microporous filter; take the filtrate and mix it with diatomaceous earth (1:1, m / m), mix well, and place it in a closed place for 20 minutes to allow it to fully absorb, and make a composite plant Esse...

Abstract

The invention discloses a composite plant extract and an application thereof in storage and mildew prevention of food grains. The composite plant extract comprises effective components of cinnamic aldehyde, citral, eugenol and mint oil (containing 33% of L-menthol). One-year corn mildew prevention experiment proves that the composite plant extract disclosed by the invention has obvious restrainingeffects on the growth of moulds of aspergillus flavus, fusarium and the like, and the production of fungus toxins, hinders and controls the quality of corn from becoming bad, and also has the effectof maintaining the physiological activity of the corn, and a high-efficient good-quality product is provided for mildew prevention, quality guaranteeing and safe storage of the corn.

Description

technical field [0001] The invention relates to the field of food safety, in particular to a compound plant extract and its application in grain storage for mildew prevention. Background technique [0002] Plant essential oils (Essential oils), also known as volatile plant essential oils (Volatile oils), are a class of secondary metabolites with a small molecular weight extracted from plants. They are highly volatile, fat-soluble and low-water-soluble, safe, It is non-toxic, has a special fragrance and strong penetrating power of the fragrance components, and is an oily liquid at room temperature. Plant essential oils are widely used as antifungal agents in the pharmaceutical and food industries, and have achieved ideal antibacterial effects (Bassolé et al., 2012). The chemical components contained in plant essential oils are complex and diverse. Often a plant essential oil contains hundreds of compounds, mainly including terpenoids, aromatic compounds, aliphatic compounds,...
