Clarification of longan juice by ultrafiltration
Abstract：In order to solve the problem of longan juice turbidity,ultrafiltration technology was applied.With permeate flux as index,the influence of pretreatment,operation pressure,temperature and feed rate were investigated.Results showed that when longan juice was first treated with centrifuging combining microfiltration,and the operation pressure 0.10 to 0.14 MPa,temperature 40 ℃ and feed rate 20 mL·s-1 were chosen,higher permeate flux could be achieved.Longan juice was clear,nutritional ingredients were basically remained when ultrafiltration was conducted under the situation.Therefore,it is feasible to clarify longan juice by ultrafiltration technology.
