AI Technical Summary

Problems solved by technology

However, Gastrodia elata has a strong harvest seasonality, which makes it difficult to meet the annual production needs of enterprises, and Gastrodia elata products are mostly dry products, which are difficult to process and eat. Most of the existing fresh-keeping Gastrodia elata are high-temperature sterilized products, and there are no research reports and public patents on quick-frozen and fresh-keeping Gastrodia elata.

Embodiment 1

[0011] Example 1: Fresh Gastrodia elata was washed with cold water, and 5 kg of basically the same size was selected and spread on an aluminum plate, placed in a low-temperature air-cooled at -25°C for 60 minutes, then put into a plastic bag and stored at -20°C for 10 months, and then placed in a high-pressure Gastrodia elata obtained after steaming and thawing and fresh gastrodia elata are slightly softer after high-pressure cooking, some juice and nutrients are lost, and the meat is slightly spongy.

Embodiment 2

[0012] Example 2: Wash fresh Gastrodia elata with cold water, select 5.1kg of basically the same size, spread it on an aluminum plate, put it in a low temperature of -75°C for 30 minutes, then put it in a plastic bag and store it in a freezer at -20°C for 10 months, and cook it under high pressure Gastrodia elata obtained after thawing and fresh gastrodia elata after high-pressure cooking are basically the same in color, fragrance, shape and texture, and the overall and fleshy quality of Gastrodia elata is firm.

Embodiment 3

[0013] Embodiment three: Fresh Gastrodia elata is washed with cold water, and 5 kg of the selected size is basically the same and placed in a liquid nitrogen quick-freezing device for quick freezing for 3 minutes, then packed into a plastic bag and stored at -20°C for 10 months, and the obtained Gastrodia elata after high-pressure cooking and thawing and The color, aroma, shape and texture of fresh Gastrodia elata after high-pressure cooking are basically the same, and the overall and fleshy quality of Gastrodia elata is firm.

Abstract

The invention relates to a quick-frozen fresh-kept gastrodia elata blume and a technology for preparing the same. The technology comprises the following steps of cleaning and grading fresh gastrodia elata blume, quick-freezing at the temperature of -20 DEG C, subpackaging and performing freezing storage to obtain the finished product, namely the quick-frozen gastrodia elata blume. After being unfrozen, the gastrodia elata blume can be used as fresh gastrodia elata blume for processing or cooking. The quick-frozen fresh-kept gastrodia elata blume provided by the invention has the advantages of high fresh-keeping effect, small loss of functional compositions such as nutritional ingredients, long shelf life and the like, and can meet perennial demands of enterprise production and markets.

Description

technical field [0001] The invention relates to a quick-frozen and fresh-keeping Gastrodia elata and its manufacturing technology. It is characterized in that the fresh Gastrodia elata is washed and graded, and the finished quick-frozen Gastrodia elata is the finished quick-frozen Gastrodia elata after quick-frozen packaging and storage below -20°C. After thawing, it can be processed or cooked as fresh Gastrodia elata. The quick-frozen and fresh-keeping Gastrodia elata obtained by the invention has the advantages of good fresh-keeping effect, less loss of nutrition and functional components, long storage period, etc., and can meet the perennial demands of enterprise production and market. Background technique [0002] Tianma ( Gastrodia elata Blume) belongs to the Orchidaceae plant, a perennial herb that grows in damp forests and has fleshy tubers underground. The tubers contain vanilla alcohol, vitamin A substances, glycosides and trace alkaloids. Food and medicine are a...
