Abstract: By using the software Design Expert 7.0 and Response Surface Method(RSM),the interaction between any two factors and its effect on extraction ratio of pectin from banana peel were studied from four factors(pH value,extraction temperature,extraction time and salting out time).The results showed that the interaction between any two factors affects the extraction ratio of pectin.There are significant effects on the extraction ratio of pectin especially in the interaction between extraction temperature and extraction time,the interaction between extraction temperature and salting out temperature,and the interaction between extraction time and salting out temperature.

Key words: pectin extraction, affecting factor, interaction
