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。

When fiber Bragg grating is pressed by local transverse force, the reflection spectra are independent of the applied length. The wavelength of split point is periodical and linearly proportinal to the applied force. And the reflectivity of split point is approximately hyperbolically tangential versus the applied position.
