This review aims to focus on microalgal as preservative potential to food chain. The main compounds responsible for these properties, like carotenoids, phenolic compounds, antioxidant vitamins, sterols and polyunsaturated fatty acids are discussed because microalgae can be cultivated under controlled conditions to improve their production. We have listed several studies performed in recent years supporting the health benefits that most of these compounds can provide. Therefore, they may represent an excellent source of preservatives in food chain once their safety as a food supplement has been also confirmed.展开更多
文摘目的在保健品维生素C片生产中应用ISO22000食品安全管理体系,预防与控制保健品维生素C片在生产、加工、贮运到销售过程中可能存在的潜在危害。方法根据ISO22000食品安全管理体系标准,采用危害分析与关键控制点(hazard analysis critical control point,HACCP)的质量管理原理,对保健品维生素C片加工中可能的潜在危害进行分析,提出相应的预防措施和监测方法,从人、机、料、法、环5个方面进行分析,并制定相应控制措施。结果确定了原料验收和金属探测2个关键控制点(critical control point,CCP),确定了关键限值和纠偏措施。同时通过制定操作性前提方案(operational prerequisite program,OPRP)与HACCP工作计划,构建了保健品维生素C片的食品安全管理体系模式,符合ISO22000体系。结论通过制定操作性前提方案,将其与HACCP中的关键控制点动态、互补地结合,将食品安全危害因素降到最低限度,更好地保障保健品安全,降低企业管理成本,提升经济收益。
