【摘要】 以成熟商陆浆果为原料,采用水提醇沉工艺进行了商陆浆果色素提取试验,并对色素粗品部分指标进行了检测。同时,利用光谱扫描对色素浸膏进行了不同pH值、不同温度、光照、柠檬酸、抗坏血酸、氯化钠、双氧水耐性等理化性质的研究,并进行了急性毒性检验。结果表明,商陆浆果红色素浸膏在偏酸性环境下(pH=4—6),对光、热、食品添加剂和氧化剂较稳定,并且无急性毒性。更多还原

【Abstract】 Red pigment is extracted from Phytolacca acinosa using the procedure of water extraction-alcohol precipitation.In this experiment we use the method of decompressed concentration and vacuum drying at low temperature.And we studied some properties of this pigment.The property of resistant to different pH value,temperature,light and citrate acid,NaCl,H 2 O 2 ,ascorbic acid in different concentration are studied using UV Scanning.Finally,we carried on the toxicity testing using little white mice.The results showed that the pigment is more stable at pH equal to4-6,and its resistant to light,heating,food additives and oxidative reagents is good.In addition,the pigment has no toxicity.更多还原
