摘 要: 探讨了从柚子皮提取果胶的温度、酸度、时间等条件对产率的影响,其适宜条件是:90-95℃下,加入0.395%的盐酸,提取45min。还探讨了双氧水对果波脱色及对果胶质量的影响,适宜的条件是15℃左右加入5-7ml/100ml提取液的30%双氧水,放置1-2天,即可获得色泽很好的果胶产品。 It was discussed the influence of temperature, acidity and time of extraction on yield of pectin extracted from shaddock skins. Optium conditions were: at 90-95℃, added 0. 395% in weight of hydrogen chloride and abstracted for 45min. Optium decolored conditions were: at 15℃, added 5-7% in volume of hydrogen peroxide(30wt. %), placed for 1-2days.
