The invention discloses a compound
navel orange
preservative prepared from
plant extract which is prepared by combining
plant extract, food
preservative, stabilizer and
acidity regulator. The invention aims to replace
pesticide bactericide, which is adopted as
antibacterial agent during the storage period of
navel oranges in China all the time, with the compound
navel orange
preservative, so as to solve the problems of
food safety and environment
pollution caused by
pesticide application. The main technical characteristics of the compound
navel orange preservative are as follows: the principal components of the preservative comprise 10-15% of a
magnolia officinalis extract, 20-30% of a clove extract, 10-20% of
potassium sorbate, 10-20% of
propylparaben, 2-5% of
citric acid and 1-5% of stabilizer. The compound
navel orange preservative is brown
emulsion. When in use, the compound
navel orange preservative is diluted with water, wherein the volume of the diluted compound navel orange preservative is 20 times of that of the compound navel orange preservative before
dilution; navel oranges are soaked in the compound navel orange preservative for 30 seconds; after being subjected to natural
air drying, the navel oranges are stored or subjected to
postharvest commercialization treatment. The compound navel orange preservative can efficiently lower the rotting rate of the navel oranges, and
delay the quality losses of the navel oranges during the storage and fresh-preservation period of the navel oranges. The compound navel orange preservative can also be applicable to the
postharvest storage and fresh-preservation of other fruits and is particularly suitable for the storage and
corrosion protection of citrus fruits.
