Abstract

The present invention discloses a limonium wrightii preservative. The limonium wrightii preservative is mainly prepared from starch, water, ethanol, serpentine powder, propolis extract, sodium hydrosulfite, wasabia japonica sauce, chitin, sodium benzoate, sodium dehydroacetate, citric acids and sodium citrate. The present invention also discloses a processing technology of the limonium wrightii preservative. The starch, serpentine powder, propolis extract, wasabia japonica sauce and other natural raw materials are used as the main raw materials of the preservative, and the prepared preservative is safe, non-toxic and environmentally friendly. The processing technology is simple, safe and convenient, and no environmentally unfriendly contaminants are produced during the preparation process of the preservative. After being treated by the preservative, the shelf life of the limonium wrightii is greatly extended reaching up to several months without deterioration, and the long-term preserved fresh limonium wrightii is low in weight loss rate and free of peculiar smell.

Description

technical field [0001] The invention relates to the field of fresh-keeping of agricultural products, in particular to a sea hibiscus fresh-keeping agent and a processing technology thereof. Background technique [0002] Sea hibiscus, a plant of the family Dianaceae, 30-100cm high, cylindrical stem, multi-branched, perennial erect herb with short stalk; leaves rhombus-ovate to egg-shaped oblong, 2-3cm long, 1-2cm wide, The apex is blunt, with a short pointed tip, the base is wide, cuneate to cuneate and extends downward on the petiole, with powder on both sides, the underside is off-white, and the edge is slightly lobed; the cymose is axillary, and integrates small spike-like panicles at the top of the branch; female flowers The bracts of the fruit are diamond-shaped and broadly ovate, and the edges of the fruit bracts are only conjoined at the base. When the fruit is ripe, the cork swells, without appendages, and the edges have triangular serrations. The flowering and fruiti...
