Adequate nourishment and sustenance of human body rely on the intake and absorption of sufficient dietary nutrients. Proteins derived from plant source are recently gaining popularity due to its increased popularity among vegetarian diet. Moreover, the negative impact of animal protein production on the environment and awareness to produce protein through sustainable means are gaining pace. Plant proteins are mainly serve the purpose of providing good health/nutrition and is recommended in various disease conditions, including heart diseases, diabetes, obesity and cancer. This review aims to delineate the recent developments on the extraction of protein from plant sources using conventional (solvent and alkali-based) and advanced green extraction technologies viz. biochemical extraction (single and concoction of enzymes), and physical extraction (ultrasound-, pulse electric field-, microwave- and high pressure-assisted extraction). It is evident from the findings that novel cell disruptive techniques are proven to be more efficient with respect to protein recovery and posing minimal environmental pollution. Utilizing efficient, cost effective, and eco-friendly techniques for protein extraction can help to decipher the key challenges faced by food processing industries.

人体的充足营养和营养依赖于摄取和吸收足够的饮食营养。来自植物来源的蛋白质由于其在素食中的日益流行而最近越来越受欢迎。此外，动物蛋白生产对环境的负面影响以及通过可持续手段生产蛋白的意识正在逐步提高。植物蛋白主要用于提供良好的健康/营养，并推荐用于多种疾病，包括心脏病，糖尿病，肥胖症和癌症。这篇综述旨在描述使用传统的（基于溶剂和碱的）和先进的绿色提取技术从植物来源提取蛋白质的最新进展。生化提取（酶的单一和混合），和物理提取（超声波，脉冲电场，微波和高压辅助提取）。从发现中可以明显看出，新型细胞破坏技术被证明在蛋白质回收和降低环境污染方面更为有效。利用高效，具有成本效益和生态友好的技术进行蛋白质提取可以帮助解读食品加工行业面临的主要挑战。
