众所周知,食盐为白色晶体,但近十年来随着加碘食用盐普及,反映食盐变黄的现象时有发生。文章通过对多年工作实践进行深入研究,认为加碘食用盐由于在生产中添加了碘剂和抗结剂在一定条件下发生化学反应造成了食盐的颜色变黄。 相似文献

亚铁氰化钾为国标允许添加的食盐抗结剂,其可以明显改善食盐的流动性。本文采用分光光度法,以硫酸亚铁为显色剂,对菏泽市市售15批食盐中的亚铁氰化钾(以[Fe(CN)6]4-计)含量进行测定。结果显示,15批食盐中有2批不合格,3批未检出亚铁氰化钾,其余批次的亚铁氰化钾含量在4~7mg/kg之间。 相似文献

添加剂的添加量会影响食用盐的白度。笔者在此基础上进行了更进一层的分析,通过多次试验检测得出了在成品盐粒度均匀的情况下不同抗结剂的添加量的有效控制范围,使之既满足国家标准添加要求,又能满足食盐抗结和白度要求。 相似文献

沙棘果渣是由沙棘果汁生产加工过程中产生的副产品,具有较高的营养及利用价值。为了提高沙棘加工副产物的利用率,用沙棘榨汁后剩余的去籽果渣为原料,与纯沙棘果粉进行比较,研究沙棘果渣、抗结剂、果渣-抗结剂混合对沙棘果粉抗结的影响,以沙棘果粉结块率和流动性为指标,通过双指标加权法对沙棘果粉抗结条件进行综合评分。结果表明,沙棘果渣-抗结剂混合的抗结效果好,由单因素的试验结果,采用响应面软件分析,其最优条件以果渣粒度100目、果渣用量为14.50%、二氧化硅添加量为1.30%时,在此条件下沙棘果粉的休止角为47.55°、结块率为25.80%,其综合评分值为69.92分。说明,沙棘果渣-抗结剂混合能够较好的抑制沙棘果粉结块现象。本研究为进一步解决沙棘果粉结块的问题提供了思路。 相似文献

ABSTRACTRed Lake Diatomaceous Earth (DE) is a naturally occurring blend of diatomaceous earth and calcium bentonite that can be used as an anti-caking agent in animal feed and contains naturally occurring dioxins. A quantitative risk assessment was conducted to assess potential human health risk associated with consumption of edible tissues from livestock exposed to dioxins via feed containing Red Lake DE. Empirical data characterising the transfer of dioxins to eggs and other tissues in chickens demonstrate that resulting concentrations in eggs are lower than those found in the general food supply. These data also provided product-specific input for a risk assessment conducted both with default parameters and with media-specific input from the feed study. Results demonstrate that exposure to dioxins in edible tissue from livestock that consumed Red Lake DE in feed would not be associated with an increased risk to humans. Findings from this assessment highlight the utility and importance of accounting for bioavailability as part of health-based risk assessment and provide information critical to risk managers in determining the safe use of Red Lake DE as an anticaking agent in livestock and pet feed. 相似文献
