Broccoli preservation processing methods, understand how to cultivate edible fungi

The main points of broccoli preservation and processing methods are as follows:

① Quality standard of raw materials: fresh and compact flower buds, regular flower buds, fine particles, no Gypsophila paniculata, bright green color, no diseases and insect pests, no mechanical damage, no moldy, rotten, soft, discolored, deformed. The plant height is more than 14 cm, and the flower bud (calculated by the shortest diameter) is 11-13.

② Process flow: raw materials into the warehouse precooling → head removal → leaf trimming → ice water immersion → packing, ice (7-8/box) → refrigeration → delivery

③ Raw material acceptance and pre-cooling: according to the raw material standard acceptance, remove pests, disease spots, mechanical injuries and other substandard raw materials. Broccoli should be packed with leaves in clean square plastic baskets, transport vehicles must be clean, no odor. The accepted raw materials shall be put into the warehouse for precooling in time, and the temperature shall be 0-2℃.

4. De-heading and leaf trimming: For qualified products, use a stainless steel knife to remove the head. The tool is clean and sharp, and the head is cut smoothly without inclination. Broccoli leaves must be removed again when pruning pests, mechanical injuries and other unqualified products, when pruning the knife outward, to prevent damage to the flower stem, pruning degree The following specifications:

A, color bright green 11-13cm, plant height 14cm,38 in/CTN, all branches and leaves removed;

B, bright green 12-13.5cm, plant height 14cm,30 in/CTN, leaves and branches, leaves and buds level, branches and branches higher than buds 2cm;

C, bright green 12-13.5cm, plant height 19cm,24 in/CTN, leaves, leaves higher than bud 2 cm.

5. Immersion in ice water, packing and icing:

The processed qualified products shall be packed in time (calcium plastic box) after being soaked in ice water, handled with care to prevent damage to flower buds and reject unqualified products. Print the production date, specification and packaging group on the outside of the box. Send it to the refrigerator immediately after loading to add ice chips. When adding ice, be sure to fill the gap and add enough ice chips on the surface of the box. Send it to the refrigerator immediately for refrigeration. The ice used must be clean and free of impurities. It does not meet the export standards. The temperature should not be too low.

Packing requirements:

1. Each box of flower balls is uniform in size and placed in a standardized manner.

2. The varieties of bulbs in each box are consistent.

3, ice 7-8kg/box.

refrigerated

Storage temperature 0℃, cold storage time more than 24 hours, out of stock must ensure that the temperature of the flower bulb is about 2℃ (can be stored for 1 month).

issue

When the product is loaded into the cabinet, enough ice chips must be added into the box again, and the advanced warehouse products must be shipped first to prevent the backlog from affecting the quality and temperature. The whole loading time does not exceed 2.5 hours, and the freezer temperature is 0-1℃.
