Extraction of edible red pigmengt from solanum nigrum fruit by optimum seeked process conditions, determined single factor condition, designed orthogonal layout, and measured absorbance at 527nm wavelength, weighed up the pigment extracting effect and stability. The most favoured extracte conditions were determined as follows: The extracting regent was citric acid hydrotropic solution, pH was 1.72, the quantities of added sample to the solution was 3.35g/100mL, the temperature was 60℃, the extracting time w...

以成熟的龙葵果为原料提取食用红色素，通过优化工艺、确定单因素条件、设计正交试验，以527nm波长的吸光度值衡量色素提取效果和稳定性；最优化的提取条件为：柠檬酸水溶液提取剂pH为1.72，样品加量3.35g/100mL，提取温度60℃，浸提时间60min；龙葵红色素提取液长期接触光、空气和Fe3+，稳定性下降，因此，在提取、干燥和储存时要尽量避免长时间接触光和空气、避免与铁制容器直接接触。

WARNING:This product contains crystalline silica,which in airborne particles of respirable size is known to cause cancer.

注意：如眼神接触、洗净，用温水如过敏现象持续发生，就医，在皮肤接触，用肥皂和水警告：本品含硅晶体，在空气中的微粒的大小是呼吸致癌让儿童接触不到的地方。

Thus different mediums have been used between the two contact surfaces in order to investigate the variations in the normal force with the feeding level under both adhesive- and non-adhesive-contact.
