Greenness-protecting and brittleness-keeping compound agent for heracleum moellendorffii hance

Abstract

The invention relates to a greenness-protecting and brittleness-keeping compound agent for heracleum moellendorffii hance and belongs to the technical field of processing of agricultural products. A method comprises the concrete steps: after grading and cleaning fresh heracleum moellendorffii hance, soaking the heracleum moellendorffii hance into a greenness-protecting and brittleness-keeping water solution composed of 0.03%-0.30%(w / v) of tea polyphenol, 0.02%-0.25%(w / v) of ascorbic acid, 0.06%-0.50%(w / v) of nobiletin, 0.01%-0.30%(w / v) of calcium lactate and 0.01%-0.30%(w / v) of zinc chloride;and performing treatment with an ultrasonic wave device for 10-15min, rinsing, dewatering, cooling, vacuum packaging and low-temperature storage. After the heracleum moellendorffii hance is treated bythe above steps, degradation of chlorophyll and decomposition and browning of pectin can be obviously postponed and the respiratory intensity and peroxidase activity of the heracleum moellendorffii hance can be obviously reduced. The method is a green, environment-friendly, safe, economic and high-efficiency greenness-protecting and brittleness-keeping method and provides a research basis for theresearch and development of the related products of the heracleum moellendorffii hance in the future.

Description

technical field [0001] The invention discloses a component of a compound agent for protecting green and preserving crispness of old celery, which belongs to the technical field of agricultural product processing, and in particular relates to a processing method of a compound agent for protecting green and preserving crispness of old celery. Background technique [0002] Laoshan celery, also known as "Northeast Niu Fangfeng" and "Mountain Celery", belongs to the perennial herb of the Umbelliferae family. It mainly grows in deep mountains and grasslands. It is a wild vegetable that is abundant in Northeast China. Old celery is rich in protein, vitamins, minerals, cellulose, sterols, and coumarin compounds, which can effectively prevent and treat constipation, high blood pressure, high blood fat, and cardiovascular diseases. Old celery is rich in nutritional value, delicious and unique in taste. It is a good product on the table of consumers. [0003] Due to the relatively co...

Problems solved by technology

[0003] Due to the relatively concentrated collection time of old celery, the dormant period of seeds, seasonality and other limiting factors, it cannot be supplied in four seasons, and it is difficult to meet the large demand in the market, which has a certain impact on the development of the old celery industry.

In addition to the above limiting factors, old celery is prone to wilting, aging, yellowing, softening and fibrosis after picking, making it difficult for long-distance transportation and sales of old celery
