其他信息

  • RTECS号:LX8580000
  • 所属类别一:食品添加剂: 增稠剂和胶凝剂
  • 参考质量标准二:GB 6783-94(强制性标准) 尚有稳定泡沫的作用,本身也有起泡性,尤其在凝固温度附近时,起泡性更强。粘度因分子量分布情况而异,粘度与凝胶强度尚受pH、温度、电解质等的影响。
  • 生产方法:主要有石灰乳法和盐酸法。1.石灰乳法 将牛皮、猪皮等变质的下脚皮的内层油脂乱去,切成小块,放在3.5%-4.0%的石灰乳中浸泡约30-40d,中间换石灰乳4-6次。在浸泡过程中,经常搅拌,使上下浸泡均匀。将浸泡的生皮从石乳缸中取出,用水洗净,在搅拌下10%盐酸中和3-4h,洗涤后pH应在6.0-6.5。然后将肉皮按1:1加水,加热蒸煮,控制温度为60-70℃,每隔一定时间抽取胶水,用清洁纱布趁热过滤,共抽5-6次。将稀胶水送入蒸发器浓缩,使相对密度为1.03-1.07。热胶移入铝盘冷却,把冷胶往放在不锈钢筛网上,送入烘房鼓风干燥,温度严格控制在28℃左右。干燥的胶片用颗粒粉碎即得成品。按猪皮重量计,收率约22%。2.盐酸法 将家畜的杂骨,脊骨及小骨粉碎,用苯在45-50℃提油后水洗。洗净利的骨头,用3.5-4.0%的盐酸浸泡,主骨头柔软后即得粗制骨素,水洗,使水溶液pH在3.5左右,加石灰乳可制饲料磷酸氢钙及干燥氯化钙。将骨头再用3.0%-3.5%以上的石灰乳浸泡30-50d(中间换石灰乳5-6次),取出,用水洗约1h,将此次净骨素用0.2盐酸进行第一次中和,待pH降至3.5-4.0,放掉中和液,另加入清水,再用0.5%盐酸中和约2h。当酸浓度降至0.2-0.25%时,立即将酸浓度提高到1%,并维持这一浓度直至到达中和终点(pH3.0)。中和完毕,将骨素用清水充分洗涤,浸泡4-5h。然后用氢氧化钠溶液洗涤,稀碱液浸泡16-20h后用清水冲洗,即得精制骨素。精制骨素经过7道熬胶得到胶水,各道熬胶的加水量,温度分别掌握,加水量逐道减少,熬胶温度逐道提高,从第一道的64℃提高到第七道的85℃。出胶的浓度从第一道到第七道,也从8%降低至2-3%。共熬40h。将得到的稀胶水过滤,浓缩,使用对密度达1.025-1.075,放在胶盒上冷冻,然后刨成薄片置于筛网上,送入烘烘房鼓风干燥,温度从25℃逐渐提高至60℃。干燥后即成为成品。各道熬胶制得的明交质量不同,按批道分为照相胶,食用胶,最后为用于制蛋白胨的烘胶,好胶率大于60%。每吨产品消耗:性骨约7t;30%的盐酸约7t。常德市鼎城区常沅明胶厂利用制革生产中的铬革边角废料(蓝矾皮)生产有胶,采用流程如下:蓝矾皮→破碎→浸灰→漂浸→浸灰→漂浸→抽提→浓缩→滴胶→烘干→粉碎。原料消耗(kg/t)蓝矾皮
