Abstract

The invention discloses a natural preservative for citrus gonggan. The natural preservative comprises the following raw materials in parts by weight. The composition is prepared from the following components in parts by weight: 20-30 parts of a plant compound agent, 1-6 parts of 2, 4-D sodium salt powder, 1-5 parts of sorbitan monostearate, 1-2 parts of a chitosan penetration agent and 1-2 parts of potassium sorbate. The plant compound agent prepared from the lotus leaves and the bamboo leaves according to the proportion has efficient anti-corrosion and fresh-keeping functions, by introducing the diatomite corrosion inhibitor, an extracting solution extracted from the lotus leaves and the bamboo leaves can be conveniently permeated into the diatomite slow-release agent, and the corrosion inhibitor is prepared from the diatomite, wollastonite and clay according to the proportion, so that the corrosion-resistant effect is good. The clay and the diatomite are crossed and matched to form a stable three-dimensional system, and the extracting solution is dissolved in the three-dimensional system, so that stable and long-term antibacterial, anticorrosive and fresh-keeping effects can be kept; the wollastonite has carrying capacity through the needle-shaped structure, so that the wollastonite is matched with the extracting solution to penetrate into pathogenic bacteria, and further, the better antibacterial and bactericidal capacity is achieved.
