Separation and Abstraction of Flavonoid and Pectin from Orange Peel

Objective: making L₉(3⁴) and L₁₆(4⁴) orthogonal experiments for separtion and abstraction of flavonoid and pection from orange peel. Results: the better craft conditions for withdrawing the flavanone are solid/fluid ratio 1:30,supersonic process time 55 mins,processing temperature 50℃.The better craft conditions for with drawing the pection are temperature 70℃,time 55 mins,solid/fluid ratio 1:25,pH 2.0.
