Problems solved by technology

In the past, fresh-keeping methods for wild rice stems were often stored by low temperature + plastic wrap, weakly acidic potential water, ultra-high pressure, controlled atmosphere, coating, and heat treatment. This method often has poor fresh-keeping effects. Satisfying the fast-growing supermarket low-temperature freezer shelf sales preservation, large kitchen vegetable distribution, no better technical application has been seen, and its products cannot meet the increasing consumers' demand for food safety and delicious flavor in terms of freshness and flavor requirements and attention

Embodiment 1

[0050] This embodiment provides a fresh-keeping treatment method for wild rice stems, specifically using fresh wild wild rice stems as a raw material, and performing the fresh-keeping treatment according to the following process:

[0051] Harvesting: When harvesting, the outer leaf sheaths of Zizania are retained, and the baskets are transported back to the product processing room within 3 hours after harvest, the inedible leaf sheaths are peeled off, and then the damage is removed, and the Zizania of the same size is screened as the primary product of Zizania;

[0052] Cleaning: transport the primary products of Zizania zizania along with the conveyor belt to the cold water clear water pool to clean the dust on the surface. The temperature of the cold water pool is 0-10°C, and the cleaning time is 1 to 5 minutes. 100-200ppm sodium hypochloride solution, immersion disinfection time 2-3min;

[0053] Heat Shock: The cleaned Zizania primary product is transported with the conveyo...

Embodiment 2

[0074] Harvest and select the inedible leaf sheath parts, remove the damage, and the same size of the first product of Zizania zizania; use the conveyor belt to transport the dust to the cold water pool to clean the surface dust, the temperature is less than 10°C, and the cleaning time is less than 5 minutes, and then the conveyor belt is transported to the disinfection pool To remove surface microorganisms, use 100-200ppm sodium hypochloride solution in the disinfection pool, soak for 2-3 minutes; then transport the hot water pool for heat shock treatment, keep the temperature at 50-54°C, and keep for 30 seconds to 2 minutes; The belt passes through the blower tunnel, and the water on the air-dried wild rice stem is exposed; the initial product is transported to the light treatment room along with the conveyor belt, and the cold plate is placed under the UV-C lamp. , control the irradiation dose to 4.30 KJ m -2 , the irradiation time is 8-10 minutes; the final primary product...

Embodiment 3

[0076] Harvest and select the inedible leaf sheath parts, remove the damage, and the same size of the first product of Zizania zizania; use the conveyor belt to transport the dust to the cold water pool to clean the surface dust, the temperature is less than 10°C, and the cleaning time is less than 5 minutes, and then the conveyor belt is transported to the disinfection pool To remove surface microorganisms, use 100-200ppm sodium hypochloride solution in the disinfection pool, soak for 2-3 minutes; then manually pour it into a cold plate and place it under the UV-C lamp. 0.3-0.5 meters below, control the irradiation dose to 4.20KJ m -2 , the irradiation time is 8-10 minutes; then it is transported to the hot water pool for heat shock treatment, the temperature is kept at 50-54°C, and the holding time is 30 seconds to 2 minutes; then the conveyor belt passes through the blower tunnel, and the air-dried wild rice stems are exposed to water; The conveyor belt is transported to th...

Abstract

The invention provides a fresh-maintaining device and method for zizania latifolia, and belongs to the technical field of fresh maintaining of the zizania latifolia. The fresh-maintaining method for the zizania latifolia comprises the steps of washing, heat shock for 30-120 seconds at the temperature of 50-54 DEG C, air drying, UV-C lighting and storage. The invention further provides the fresh-maintaining device for the zizania latifolia based on the fresh-maintaining method. The device comprises a processing table and a supporting table installed on the bottom of the processing table, the left side of the processing table is connected with a food packaging machine, fresh-maintaining device bodies are uniformly distributed in the horizontal direction, a protection cover matched with the processing table is movably installed above the processing table, and a feeding inlet is formed in the right side end of the protection cover. The device is simple in structure and low in manufacturing cost, manual intervention is not needed in the whole fresh-maintaining process, new contaminations introduced by lateral manual operation are effectively avoided, the freshness of the zizania latifolia is totally mechanically maintained instead of manual fresh maintaining, and the economic benefits are obvious.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping wild rice stems, in particular to a fresh-keeping processing equipment and a fresh-keeping method for wild wild rice shoots. Background technique [0002] Zizania latifolia (Zizania latifolia), which belongs to the genus Zizania of the Gramineae family, is also known as Zizania bamboo shoots, bamboo shoots, and water melons. Zizania is native to China, Southeast Asia and India, and has a long history of cultivation. Zizania is the second largest aquatic vegetable in my country. The eastern and southern regions of China are the main planting areas. The edible part of Zizania is the young stem. The outside of the stem is tightly wrapped by non-edible leaf sheaths. Before eating of the leaf sheath. Fresh water bamboo has rich nutritional value, mainly including: reducing sugar, crude fat, crude fiber, lignin, soluble solids, protein and inorganic salts and other substances. In addition, Zizan...
