Aquatic products processing, packaging and sales i

Aquatic products processing and packaging sales in supermarkets (Part 1)

key words: aquatic products

the aquatic products Department of the supermarket estimates the items and quantities of aquatic products needed for sales in the next day according to the sales situation of aquatic products on the same day, as well as the weather conditions and seasons of the next day, and places orders with the headquarters or the purchasing staff respectively. Purchasers count the purchase quantity of various aquatic crystals according to the demand, then purchase from the wholesale market or manufacturers, and send them back to the treatment plant for treatment, packaging, pricing, display, sales, etc, Its operation process is as follows:

order → statistics → purchase → acceptance → ice coating → raw material warehousing → primary treatment → cold brine machine → secondary treatment → cartoning → packaging → pricing → shipment → preparation room → distribution → supermarket → display → sales → order the next stage of breakthrough will be in the window goods

I. raw material procurement

the raw materials of aquatic products come from four main channels: direct transportation and marketing, wholesale markets, traders, and processing plants, which are described as follows:

(I) direct transportation and marketing

in order to shorten the transportation and marketing channels of agricultural, fishery, and animal husbandry products, improve farmers' income, and reduce the purchase cost of supermarkets, in recent years, the agricultural administration units have assisted the fishing associations in various regions to set up fishery sub loading yards for processing To pack some aquatic products required by the supermarket, such as small packaged finished products such as clams, snails, blackflies, etc., the supermarket can order the required quantity directly from the fishing association

(II) wholesale market

fish market (wholesale market) is the distribution center of fishery goods in the consumer place, with a complete range of aquatic products, and the price depends on the supply and demand situation at that time. Generally speaking, it is quite reasonable; Small quantity, farmed fish, fish caught now, etc. can be purchased from the wholesale market

(III) traders

frozen ocean fishing goods. Most of them are imported by traders, stored in freezers, and then sold to wholesalers or processors. Such fishery goods can be purchased directly from traders

(IV) the contradiction between supply and demand of lithium battery copper foil in the processing plant is still prominent. Shrimp, shellfish and dried fish are processed by the processing plant and then stored, or directly sent to the wholesale market for wholesale sale. Such products can be purchased directly from the processing plant

II. Acceptance

the price of aquatic products is quite different due to the large and small fish bodies. Therefore, during acceptance, it is necessary to check the specification of the purchase order in detail, weigh and check the quantity in detail, and use the central thermometer to test the surface temperature and central temperature of raw materials respectively. The surface temperature of cold collections should be below 5 ℃, while the center temperature of frozen products should be below – 18 ℃. In addition, the acceptance personnel should also check the freshness of the fish by visual inspection. Inferior products should be rejected, otherwise it will affect the image of the supermarket

-. Ice application

ice application refers to the use of crushed ice to reduce the product temperature. The farmed warm water fish or coastal freshly fished fish purchased by purchasers from the wholesale market, which is not only the production field of the two industries, have been dissolved in the wholesale market due to the influence of the external environment during the transportation process, so that the fish body has a warming phenomenon. If it is limited to the operation arrangement, the raw materials may be delayed in processing. In order to avoid affecting the freshness, crushed ice must be applied again to maintain the freshness of the fish

III. warehousing and thawing of raw materials

in order to maintain the freshness of aquatic products, temperature management must be done well, especially raw materials. Raw materials that cannot be processed at once should be sent to freezing or cold storage immediately according to the nature of the raw materials

the raw materials of frozen products are frozen. Before processing, they must be thawed to soften the fish before cutting. There are three thawing methods for aquatic products:

(I) thawing method in cold storage

(II) "the new chemical materials listed in the catalogue are also the cold brine machine thawing method of our industry's current key development products.

(III) water thawing method. Among them, the cold storage thawing method is the safest, and it is not easy to cause the phenomenon of water loss. The freshness and taste of the fish after thawing are good. The day before processing, the frozen raw materials will be moved to the cold storage, and the temperature will gradually rise to about 0 ℃ before processing
