在骨明胶的生产中,透过率的高低、色泽的深浅、灰分的高低、离子杂质的多少,都受明胶纯度的影响。为提高明胶的纯度,一般在淡胶液中要有去除颗粒性及有机杂质的净化处理,而许多厂家只用一种粗处理——用过滤棉为介质的板框压滤,除去悬浮于淡胶液中粗糙的大颗粒杂质及部分中等颗粒的杂质,细微颗 In the production of bone gelatin, the level of transmittance, the depth of color, the level of ash, the amount of ionic impurities, are affected by the purity of gelatin. In order to improve the purity of gelatin, it is generally necessary to remove the granularity and organic impurities in the light glue solution, and many manufacturers only use one kind of rough treatment - press filter with the filter cotton as the medium to remove the suspension in the light Glue coarse particles of impurities and some medium-sized impurities, fine particles
