Goat meat is the main source of animal protein in developing countries, particularly in Asia and Africa. Goat meat consumption has also increased in the US in the recent years due to the growing ethnic population. The digestive tract of goat is a natural habitat for organisms. While researchers have long focused on postharvest intervention strategies to control outbreaks, recent works have also included preharvest methodologies. In goats, these include minimizing animal stress, manipulating diet a few weeks prior to processing, feeding diets high in tannins, controlling feed deprivation times while preparing for processing, and spray washing goats prior to slaughter. Postharvest intervention methods studied in small ruminant meats have included spray washing using water, organic acids, ozonated water, and electrolyzed water, and the use of ultraviolet (UV) light, pulsed UV-light, sonication, low-voltage electricity, organic oils, and hurdle technologies. These intervention methods show a strong antimicrobial activity and are considered environmentally friendly. However, cost-effectiveness, ease of application, and possible negative effects on meat quality characteristics must be carefully considered before adopting any intervention strategy for a given meat processing operation. As discussed in this review paper, novel pre- and post-harvest intervention methods show significant potential for future applications in goat farms and processing plants.
山羊肉是发展中国家动物蛋白的主要来源,尤其是在亚洲和非洲。近年来,由于少数民族人口的增加,美国的山羊肉消费量也有所上升。山羊的消化道是微生物的自然栖息地。虽然研究人员长期以来一直专注于收获后控制疫情的干预策略,但最近的研究也包括收获前的方法。在山羊养殖中,这些方法包括尽量减少动物应激、在加工前几周调整饮食、饲喂富含单宁的饲料、在准备加工时控制禁食时间,以及在屠宰前对山羊进行喷淋清洗。在小反刍动物肉类中研究的收获后干预方法包括用水、有机酸、臭氧水和电解水进行喷淋清洗,以及使用紫外线(UV)、脉冲紫外线、超声处理、低电压电、有机油和栅栏技术。这些干预方法具有很强的抗菌活性,被认为是环保的。然而,在为特定的肉类加工操作采用任何干预策略之前,必须仔细考虑成本效益、应用的便利性以及对肉质特性可能产生的负面影响。如本综述文章所述,新型的收获前和收获后干预方法在山羊养殖场和加工厂的未来应用中显示出巨大潜力。
