獺兔皮的防腐的保存方式

發(fā)布日期:2017-03-29 來(lái)源:http://m.114gov.cn 發(fā)布人:admin

剛從獺兔體上剝下的生皮,含有大量的水分、蛋白質(zhì)和脂肪,是各種微生物繁殖的培養(yǎng)基,如不及時(shí)進(jìn)行防腐處理,就可能腐敗變質(zhì),影響毛皮品質(zhì)。
Just from the rabbit body stripped skin, contains a lot of water, protein and fat, is a good medium of various microorganisms, such as not timely treatment, it may affect the quality of fur spoilage.
干燥法 通過(guò)干燥使鮮皮中的含水量降12%~16%,以抑制細(xì)菌繁殖,達(dá)到防腐的目的,鮮皮干燥的更適溫度為20℃~30℃,溫度低于20℃,水分蒸發(fā)緩慢,干燥時(shí)間長(zhǎng),可能使皮張腐爛,溫度超過(guò)30℃,皮板表面水分蒸發(fā)快,易使皮張表面收縮或使膠原膠化,阻止水分蒸發(fā),成為外干內(nèi)溫狀態(tài),干燥不勻會(huì)使生皮浸水不勻,影響以后的加工操作。
Drying method by drying the fresh skin of the moisture content of 12% ~ 16%, to inhibit bacterial growth, achieve the purpose of antisepsis, the optimum temperature is 20 DEG to 30 DEG. The fresh skin dry, the temperature is below 20 DEG C, slow evaporation, long drying time, can rot the skin, skin temperature over 30 the plate surface moisture to evaporate quickly, easy to make the skin surface or the collagen gel contraction, prevent water evaporation, become dry temperature and dry state, will cause uneven soaking unevenness, affect the machining operation.

干燥防腐的缺點(diǎn)是皮板僵硬,容易折裂,難于浸軟,且儲(chǔ)藏時(shí)易受蟲(chóng)蝕損失。
The disadvantage is the skin dry antiseptic stiff, easy to break, it is difficult to soak and storage and is susceptible to erosion loss.
鹽腌法 鹽腌法利用干燥食鹽或鹽水處理鮮皮,是防止生皮腐爛更普通、更可靠的方法。用鹽量一般為皮重的20%,將其均勻撒布于皮面,然后板面對(duì)板面堆疊1周左右,使鹽溶液逐漸滲入皮內(nèi),直皮內(nèi)和皮外的鹽溶液濃度平衡,達(dá)到防腐的目的。鹽腌法防腐的毛皮,適于長(zhǎng)時(shí)間保存,不易遭受蟲(chóng)蝕。
By using the method of salting salted dry salt or brine treatment of fresh skin, prevent rotting hides the most common and reliable method. The use of salt is generally 20% of the tare, evenly distributed on the surface, and then board the face plate stack about 1 weeks, the concentration of salt solution gradually infiltrated into the skin, skin and skin until balanced salt solution, achieve the purpose of antisepsis. The invention relates to a method for preserving fur, which is suitable for long time preservation, and is not easy to be damaged by insects.
鹽干法 鹽干法是鹽腌和干燥兩種防腐法的結(jié)合,即先鹽腌后干燥,使原料皮中水分含量降20%以下,鮮皮經(jīng)鹽腌,在干燥過(guò)程中鹽溶液逐漸濃縮,細(xì)菌活動(dòng)受到抑制,再經(jīng)干燥處理,達(dá)到防腐的目的。
Dry salt salt is a combination of dry salted and dried two kinds of antiseptic methods, namely the first salt after drying, the moisture content of raw hides in below 20%, fresh peel by salting, drying in the process of salt solution is gradually concentrated, bacterial activity was inhibited, drying, attain the purpose of antisepsis.
鹽干法的缺點(diǎn)是干燥時(shí)由于膠原纖維束縮短,皮內(nèi)又有鹽粒形成,可能影響真皮天然結(jié)構(gòu)而降低原料皮質(zhì)。
Dry salt disadvantage is drying because of collagen fibers is shortened, and the formation of intradermal salt, may affect the structure of natural leather and lower raw material cortex.
