Quick-frozen spinach and cowpea production process

(I) Quick frozen spinach
(1) Process flow Acceptance of raw materials → Trimming → Cleaning → Bleaching, cooling → Drainage → Freezing → Ice Packing → Packaging → Freezing.
(2) Operation points Raw materials are required to use spinach with large leaves, thick and fresh leaves, complete plant shape, no loose seeds when harvesting, no water soaking, no gravity banding, high stack pressure, no mechanical injury, no pests and diseases.
Trimming and cleaning will remove roots and roots and remove dead leaves and leaves. Pick out loose strains and bolting strains. Clean it.
Blanching, cooling, then put the root into boiling water and blanch for about 30 seconds, then immerse the entire plant in the blanching for about 30 seconds. The blanched spinach was immediately put into cold water and cooled to below 10°C.
Drain, freeze, remove the water with a vibrating screen, place it in a 18cm 13cm rectangular box, spread neatly, 530g per box, depending on the amount of water. After the roots of the vegetables are well aligned, they are put into the box one by one, and then the stems and leaves outside the box are folded back toward the roots to form a rectangular block.
The rectangular spinach block was sent to a freezer below -35°C to freeze until the central temperature was -18°C.
Ice packs are dehydrated with cold water, and then tapped on the frozen boxes. The spinach in the box is placed in the ice-plating tank for ice packs: immersed in 3-5°C cold water for 3-5 seconds and quickly removed.
Pack, freeze and store 20 bags per 500 grams, net weight 10 kg. Frozen after packaging.
(3) The quality standard is greenish green; this species should have taste and odor, no odor; the tissue is fresh, the stems and leaves are thick, the plant type is complete, and the food has no coarse fiber sense.
(B) Frozen Kidney Beans
(1) Process flow Acceptance of raw materials → Selection → Cuts → Checks → Brine rinsing → Rinsing → Blanching → Cooling → Draining → Quick freezing → Packaging → Frozen storage
(2) Operation points Selection of raw materials should be selected with darker color and uniform size of cowpea varieties. The beans did not have obvious protrusions, and the tissues were fresh and tender. The color was blue-green or light green; green and light green were not mixed. The bar is straight and the cross section of the bean is about 0.5 cm in diameter. No pests, no spots, no beans.
Cut and cut and check and cut off the two tips of the beans, check and remove the pinto beans, different color beans, and impurities. Pay attention to the wormholes. Then cut into 5 cm segments or cut into pieces.
The soaked saline was soaked in 2% saline for about 15 minutes to remove floating insects and impurities. Remove the beans and rinse with water.
Blanching in boiling water for about 1.5 minutes until the color changes to bright green, taste no bean flavor. Immediately after blanching, cool with cold water. After cooling, remove the clear water with a centrifuge.
Fast-frozen pre-treated beans should be frozen as soon as possible, can be pre-cooled to 0-5 °C, and then sent to the freezer, with -35 °C cold quickly frozen.
The packaging plastic bags are packed in 250g or 500g and then packed in cartons, 10kg per carton.
The frozen and frozen process should maintain a stable temperature and humidity.
(3) The quality standard is light green or dark green, and the color is relatively uniform; it has the taste and odor that this species should have, and there is no odor; the bean pods are fresh, the strips are round and straight, the thickness is more uniform, the beans have no obvious protrusion, and the food is not thick Fiber sense.

Goji Berry is Chinese important "medicine food homology" functional genuine herbs. As the origin place and main producing areas of Chinese and world wide Goji berry, Ningxia Province has preponderant industry. Goji industry has been the important pillar in adjusting agriculture structure and transforming the economic growth pattern.

There are many problems in traditional Goji planting, such as non-standard planting, unstable quality, Goji low safety level, depending too much on chemical pesticide and fertilizer, polluting air and groundwater, delay ripening and integrating in corresponding cultivation techniques, low penetration of new technologies and extensive management. Our company began planting organic Goji berry from 2003, and has invested more than RMB 36 million. Using the mode of transferring land and subcontracting, we have established more than 75 hundred acres of organic Goji base in Zhongning, Haiyuan, Guyuan and Delingha, under the Good Agricultural Practices(GAP). High standard design, scientific management, standardize manufacture as organic standard from organic base choosing, plant breeding, planting, fertilizing, diseases and insect pests controlling, picking, to transportation, further processing, sale. We apply quality traceability system, mechanized farming, standardized management, proceeding operation, stoving and processing together.

Wolfberry Company mainly introduces Goji diseases and insect pests bio-control technology in technique, such as matrine, veratrine, Cynanchum komarovii, pyrethrum; also introduces modern high biological technology (natural biological and plant pesticides such as biological protective agent, fertilizer-making agent, soil purificant, ferment fertilizer, biological enzyme, Cynanchum komarovii), combining use "prevent", "tempt", "seal", "engineer", "change", "drug".Effective prevent and control Goji pests and diseases, achieve manufacturing "safe, effective, steady, controllable" high quality organic Goji.

Our company is the only enterprise internationally recognized organic food certifications by NOP, EU, JAS and China, is the birthplace of Chinese organic Goji berry.
