Abstract: Shucking is an indispensable step for shellfish processing. The shucking efficiency directly affects the quality of the subsequent processing. In order to gain insights into the current status and problems for the development of shellfish shucking technology and equipment in China and abroad, this article reviews the current shellfish shucking technologies and equipment such as manual shucking, thermal shucking, ultrahigh pressure shucking and microwave shucking and compares their advantages and disadvantages. The main problems existing in this area are summarized and some possible solutions are proposed. Furthermore, future trends are discussed. It is expected that this review can eich the theoretical basis of shellfish shucking and provide valuable information for technical innovation and new equipment development for shellfish shucking.

贝类肉质鲜嫩、营养丰富,富含脂质、氨基酸及活性蛋白、糖類、微量元素等营养成分,具有改善血脂、抗疲劳、提高免疫力等功效,同时又较容易捕获,因此早在渔猎时代就已成为人类的重要食材,深受消费者的喜爱[1]。2016年,中国贝类总产量约1 529 万t,占渔业总产量的22%,是产量最大的大宗水产品之一。贝类的生产和销售具有较强的地域性和季节性,呈沿海多内陆少的分布模式,90%以上的贝类分布在沿海地区,以海水养殖居多,其中以牡蛎、蛤类、扇贝和贻贝的产量最大,占贝类总产量的80%以上,而广大内陆地区贝类的产量很低,只有淡水螺和珍珠蚌的养殖稍具规模[2-4]。由于贝类常年生活在水中或滩涂等湿润环境中,离水后存活时间较短,鲜活流通与贮运难度大,因此在贝类肉多肥美、集中上市的季节,单纯依靠鲜销无法消耗其巨大的产量,需及时进行加工处理[5-6]。目前,贝类加工产品主要有干制品和冷冻品,少数烟熏、加工成罐头和保健食品等,但无论加工成何种产品大多需要先进行开壳加工处理[7-8]。由于贝类具有非常强健的闭壳肌,因此将贝肉从壳中取出并不容易,加之贝类种类繁多、形状及大小各异,且机械通用性差,研发贝类开壳新技术、研制贝类开壳新装备是实现贝类规模化加工必须要解决的主要问题[9-10]。
