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.
