Pure natural fresh gastrodia elata processing method

Abstract

The invention discloses a pure natural fresh gastrodia elata processing method. The method comprises the following steps: classifying the harvested fresh gastrodia elata in time and picking out damaged gastrodia elata, incomplete gastrodia elata and broken gastrodia elata; repeatedly washing the soil and stains on the surfaces of the classified fresh gastrodia elata by use of clear water until the surfaces are clean; killing out the cleaned fresh gastrodia elata for 15-30 minutes according to the classification condition through a steaming or stewing method, killing out completely until no white core is in the middle; forcedly ventilating the killed-out gastrodia elata and removing dampness, quickly freezing until the gastrodia elata is frozen after 20-35 percent of moisture is removed; classifying the quickly-frozen gastrodia elata and then packaging, and putting the gastrodia elata in a refrigeration house at -2 DEG C to 0 DEG C for storage. The method disclosed by the invention can be used for maintaining the taste of the fresh gastrodia elata and realizing a long storage time of the gastrodia elata.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a pure natural fresh-keeping Gastrodia elata processing method.

Problems solved by technology

However, fresh Gastrodia elata has a very short storage time. In order to achieve a longer storage time, Gastrodia elata is usually processed into dry gastrodia elata, but the dried gastrodia elata is very hard, and it needs to be softened with water before eating. Generally, it takes about two days to soften, which takes a long time; Crushing requires special equipment, so it is more troublesome to eat, and the dry Gastrodia elata also loses the taste of fresh Gastrodia elata

Therefore, the fresh-keeping method of fresh Gastrodia elata is also used to prolong the storage time, but because the traditional fresh-keeping methods add more or less toxic and harmful substances such as sulfur, bleaching powder, and preservatives, the processed Gastrodia elata is edible. It looks sour, which changes the natural taste of Gastrodia elata, and eating this kind of Gastrodia elata for a long time is not only harmful to the human body, but also has been reported to cause poisoning and even death in large amounts.

Chinese Patent Publication No. CN102860354A disclosed a "quick-frozen and fresh-keeping Gastrodia elata and its preparation technology" on January 09, 2013. It adopts the method of directly quick-freezing fresh Gastrodia elata at -20°C, sub-packaging and freezing, but this fresh method Gastrodia elata is honeycomb-shaped after thawing, and produces a lot of water. The taste and shape change greatly, and some nutrients will also be lost with the water.
