Mai Kera Na'urar bushewa Na Ganye Ya Gabatar da Hanyoyi Masu Yaki da Taskar Ganye Don sarrafa kayan lambu

Canjin canjin kayan lambu ya ƙunshi launin ruwan kasa da canje-canjen chlorophyll. Discoloration yana da mummunar tasiri akan inganci da dandano kayan lambu da aka sarrafa. Mai ƙera injin busar kayan lambu yana gabatar da matakan hana ɓarna don sarrafa kayan lambu:

Na farko, rigakafin launin ruwan kasa

Browning a cikin sarrafa kayan lambu za a iya raba zuwa browning enzyme da rashin enzymatic browning.

1. Rigakafin enzyme browning.

Ɗayan shine maganin baƙar fata. Matsakaicin zafin jiki na kayan lambu gabaɗaya shine 95 ° C zuwa 100 ° C, kuma lokacin blanching gabaɗaya minti 1 zuwa 3 ne. Ƙayyadaddun lokaci da zafin jiki sun bambanta dangane da nau'in kayan lambu.

Na biyu shine don ƙara antioxidants. Sodium erythorbate wakili ne mai ƙarfi mai ragewa, wanda zai iya hana launin ruwan kasa yadda yakamata a sarrafa kayan lambu. Matsakaicin da aka yi amfani da shi gabaɗaya daga 0.05% zuwa 0.15%.

Na uku shine maganin acid. Wato, an daidaita pH zuwa ƙasa da 6 tare da citric acid. Zai iya rage yawan aikin phenolase yadda ya kamata. Na huɗu shine keɓewar iskar oxygen. Danyen kayan da aka riga aka rigaya ana yin shi don maganin vacuum, ko kuma an nutsar da albarkatun kayan lambu a cikin ruwa ko kuma a tsoma hydrochloric acid don keɓewar iskar oxygen, kuma ana iya hana launin ruwan enzyme yadda ya kamata.

2. Rigakafin launin ruwan kasa maras enzymatic. Browning marasa enzymatic yana da yawa a sarrafa kayan lambu. Ƙayyadaddun matakan don hana launin ruwan kasa maras enzymatic sun haɗa da rigakafin wuce haddi mai zafi, zai fi dacewa 70 ° C ~ 75 ° C, haifuwa nan da nan bayan minti 3 ~ 5 minti; kula da pH a cikin 6; ajiya zazzabi sarrafawa a 10 ° C ~ 15 ° C Ya dace.

Na biyu, don hana canje-canje a cikin chlorophyll

Chlorophyll pigment ne na halitta wanda ke kula da zafi mai haske, acid, da alkali. Sabili da haka, sau da yawa yana da sauƙi don ɓacewa ko canza launi yayin sarrafawa ko adanawa, wanda ke da tasiri mai girma akan ingancin kayan lambu.

Kariyar Chlorophyll:

1. Maganin Alkali. Jiƙa kayan lambu a cikin maganin alkali mai tsarma kamar 0.01% sodium hydroxide na mintuna 20 zuwa mintuna 30. Chlorophyll yana samar da chlorophyllin, phytol, da sauransu, kuma launi har yanzu yana da haske kore. Duk da haka, wannan hanyar ba ta ɗaukar lokaci mai tsawo na kore, wanda zai iya haifar da mummunar asarar abubuwan gina jiki.

2. Sauya magnesium a cikin chlorophyll da jan karfe ko zinc. Copper acetate ko zinc sulfate bayani za a iya amfani da, maida hankali ne 0.015%, da pH ne 9, da kuma bayani da aka nutsar da minti 30. Abubuwan da aka samu na jan karfe da zinc an kafa su don zama kore na dogon lokaci. Copper yana da ayyuka mafi girma fiye da zinc, kuma ƙimar canza canjin yana da sauri, amma ragowar adadin jan ƙarfe yana iyakance ta ƙimar inganci, yayin da amincin zinc yana da girma, tasirin kariyar kore ba ta da kyau, kuma farashin yana da ƙasa. . An fi son yin amfani da shirye-shiryen zinc don kare kayan lambu. Kore
