内布拉斯加州兰开斯特县林肯市高压加工技术助推食品业：内布拉斯加大学实验室成全美高压加工中心
内布拉斯加州兰开斯特县林肯市的内布拉斯加大学林肯分校，正凭借高压加工技术在食品业崭露头角。10月28日见报的报道说，在内布拉斯加创新园区的实验室里，研究副教授玛丽-格蕾丝·达瑙把包装好的宠物食品送入高压舱，以相当于太平洋最深处六倍的压力进行杀菌，这种高压加工技术可在杀灭细菌、病毒等病原体的同时延长保质期、保留营养，顺应消费者对最少加工食品的需求。
生宠物食品是宠物食品行业增长最快的门类，而该校食品加工中心已成为企业寻求高压加工服务的首选合作方。达瑙领导的实验室拥有生物安全二级资质，可通过在食品中接种病毒或细菌、再测定杀灭病原体所需的高压参数，开展针对性的食品安全研究；相关成果已发表，包括用高压加工改善深色切面牛肉外观、同时保留营养与质地的研究。
实验室还与兽医诊断中心等合作，探讨用高压加工提升宠物食品安全、应对禽流感等病毒风险，并面向内布拉斯加推广机构人员、兽医学生和营养专业本科生开展培训。
食品创新中心将于10月30日举办公众开放日，展示支撑该州食品与农业产业的研究、技术与专长。
High-Pressure Processing Boosts Nebraska's Food Industry: University of Nebraska Lab in Lincoln Becomes a National Hub
The University of Nebraska-Lincoln in Lincoln, Lancaster County, Nebraska, is making its mark in the food industry with high-pressure processing technology. According to a report published on October 28, research associate professor Mary-Grace Danao places packaged pet food into a high-pressure chamber at Nebraska Innovation Campus, applying pressure six times that found at the deepest point of the Pacific Ocean to kill pathogens. The technology can eliminate bacteria, viruses and other pathogens while extending shelf life and preserving nutrition, meeting consumer demand for minimally processed foods.
Raw pet food is the fastest-growing segment of the pet food industry, and the university's Food Processing Center has become a go-to partner for companies seeking high-pressure processing services. Danao's laboratory holds Biosafety Level 2 certification and can conduct targeted food safety research by inoculating foods with viruses or bacteria and then measuring the pressure parameters needed to kill the pathogens. Published results include research using high-pressure processing to improve the appearance of dark-cutting beef while preserving its nutrition and texture.
The lab also works with partners such as the veterinary diagnostic center to explore using the technology to improve pet food safety and address viral risks such as avian influenza, and it provides training for Nebraska Extension personnel, veterinary students and undergraduate nutrition students.
The Food Innovation Center will hold a public open house on October 30, showcasing the research, technology and expertise supporting the state's food and agriculture industries.
