Method suitable for long-term storage of herba houttuyniae

Abstract

The present invention relates to the technical field of vegetable storage and particularly relates to a method suitable for a long-term storage of herba houttuyniae. The method comprises the followingsteps: 1) a storage place is selected; 2) the storage place is arranged: bagasse with a thickness of 1-3 cm is laid in a storehouse, then a traditional Chinese medicinal solution is sprayed at an amount of 10-15 L / m<2>, and the bagasse is placed for 10 days; 3) the herba houttuyniae is put into the storehouse: a herba houttuyniae preservation solution at an amount of 5-9 L / m<2> is sprayed; and 4)a management is conducted during a storage period: after the herba houttuyniae is put into the storehouse, a preservation powder agent at an amount of 0.1-0.7 kg / m<2> is sprayed every mouth, and water is supplemented once after 7 days. The storage method can inhibit a respiratory intensity of the herba houttuyniae, delays declines of nutrients of minerals, vitamins, etc. contained in the herba houttuyniae, suppresses activities of peroxidase and polyphenol oxidase, reduces a weight loss ratio and a rotting weight loss rate, and effectively slows down browning and aging processes of the herbahouttuyniae, so that original freshness, color and luster, crispness and mouthfeel and flavor of the herba houttuyniae at a room temperature condition can be better kept, and a storage life is prolonged.

Description

technical field [0001] The invention relates to the technical field of vegetable storage, in particular to a method suitable for long-term storage of Houttuynia cordata. Background technique [0002] Houttuynia cordata is also known as Zheergen. It is the dry above-water part of the perennial herbaceous plant Bougainvillea of ​​the family Sanbaiaceae. In summer, when the stems and leaves are lush, the flower spikes are often harvested, washed, dried in the shade or used fresh. Spicy in the mouth, slightly cold in nature; returns lung, bladder, large intestine meridian. There is heat-clearing and toxic substances removing, reducing phlegm and expulsion of pus and eliminating carbuncle, the effect of inducing diuresis for reducing swelling and treating stranguria. Indications for asthma and cough due to lung heat, lung carbuncle and vomiting of pus, throat moth, dysentery, malaria, edema, carbuncle sore, febrile stranguria, eczema, prolapse of the anus and other diseases. ...

Problems solved by technology

[0003] Moreover, the origin of Houttuynia cordata is limited, and it is mainly produced in the provinces south of the Yangtze River Basin in China. If the northern cities want to eat it, they can only rely on the transportation of Houttuynia cordata. Research shows that after storage at room temperature for 1 day, it starts to turn black, and after 2 days began to rot, therefore, the storage performance of Houttuynia cordata caused its circulation obstacles or increased transportation costs

[0004] At present, the fresh-keeping storage of Houttuynia cordata mainly adopts low temperature, smearing, respiratory depression (1-MCP), chemical treatment, etc. However, these technologies have disadvantages such as food safety, complicated operation, and unsatisfactory effect. Therefore, it is necessary to study a non-toxic , pollution-free, easy to operate, and the preservative that makes Houttuynia cordata suitable for normal temperature storage has become a current hot issue
