火龙果汁水溶液颜色的影响因素研究

Study on the Influencing Factors of Piraya Juice Aqueous Solution Color

通过单因素试验,研究了温度、加热时间、pH值和光照条件对火龙果汁水溶液吸光度和颜色的影响。结果表明,温度、加热时间、pH值和光照条件对火龙果汁水溶液的吸光度和颜色影响均较大,将火龙果汁水溶液的加热温度控制在50℃以下,加热时间不超过0.5 h,pH值维持在3.0左右,在避光条件下,可以较好地防止火龙果汁水溶液变色。

The effects of temperature, heating time, pH value and light condition on the absorbance and color of piraya juice aqueous solution were studied by single factor experiment. Results show that temperature, heating time, pH and the illumination conditions on the influencing of the piraya juice solution’s absorbance and color are larger. While heating temperature of the piraya juice aqueous solution was controlled under 50 ℃, heating time is less than 0.5 h, maintaining the p H value of the piraya juice aqueous solution at about 3.0, under the condition of avoiding light, it can be better to prevent the discoloration of the piraya juice aqueous solution.
