Absorbability of Active Carbon Influencing the Haze in Clarified Apple Juice

Abstract:

The relationship of adsorption characteristic about active carbon and the haze in clarified apple juice was investigated. Particle size and addition and adsorption temperature of active carbon were studied.0.18mm particle size with the biggest specific surface area and 0.075mm particle size with the widest microspore distribution of active carbon lowered the turbidity and contents of haze active protein and that of haze active phenolics. Contents of haze active protein and that of haze active phenolics in apple juice were decreased by increasing the adding amounts of active carbon. High temperature of adsorption showed the positive relationship with volume of haze active phenolic and the negative relationship with volume of haze active protein. Particle size of active carbon with 0.18mm or 0.075mm and addition of 15g/kg and adsorption temperature with 50°C are chosen in reducing the haze in apple juice. Absorbability of active carbon has great effects on the haze of apple juice.
