Fruit juice is an essential food product that has received significant acceptance among consumers. Harmonized concentration, preservation of nutritional constituents, and heat-responsive sensorial of fruit juices are demanding topics in food processing. Membrane separation is a promising technology to concentrate juice at minimal pressure and temperatures with excellent potential application in food industries from an economical, stable, and standard operation view. Microfiltration (MF) and ultrafiltration (UF) have also interested fruit industries owing to the increasing demand for reduced pressure-driven membranes. UF and MF membranes are widely applied in concentrating, clarifying, and purifying various edible products. However, the rising challenge in membrane technology is the fouling propensity which undermines the membrane's performance and lifespan. This review succinctly provides a clear and innovative view of the various controlling factors that could undermine the membrane performance during fruit juice clarification and concentration regarding its selectivity and permeance. In this article, various strategies for mitigating fouling anomalies during fruit juice processing using membranes, along with research opportunities, have been discussed. This concise review is anticipated to inspire a new research platform for developing an integrated approach for the next-generation membrane processes for efficient fruit juice clarification.
果汁是一种重要的食品，在消费者中获得了广泛认可。果汁的浓度协调、营养成分的保留以及对热敏感的感官特性是食品加工中备受关注的话题。从经济、稳定和标准操作的角度来看，膜分离是一种很有前景的技术，能够在最小的压力和温度下浓缩果汁，在食品工业中具有出色的潜在应用价值。由于对减压驱动膜的需求不断增加，微滤（MF）和超滤（UF）也引起了水果行业的兴趣。超滤和微滤膜广泛应用于各种可食用产品的浓缩、澄清和提纯。然而，膜技术面临的日益严峻的挑战是膜污染倾向，这会损害膜的性能和使用寿命。这篇综述简要地就果汁澄清和浓缩过程中可能影响膜性能的选择性和渗透率的各种控制因素，提供了清晰且新颖的观点。本文讨论了使用膜处理果汁过程中减轻污染异常的各种策略以及研究机会。这篇简明综述有望激发一个新的研究平台，以开发一种用于高效果汁澄清的下一代膜工艺的综合方法。
