Refrigeration: A deep dive into the deep freeze

Issue 2 2016  •  26 April 2016  •  Ruud van der Sman, Food & Biobased Research, Wageningen University & Research Centre (UR)

Freezing is an important means for food preservation as, with this technology, long term storage of high quality foods is possible. To achieve high food quality the freezing rate is an important parameter, determining ice crystal size and shape and also the mechanical stresses imparted to the food. For foods with a cellular structure the ice crystal size, with respect to the cell size, is a critical measure, determining the texture and water holding capability of the food after thawing. If ice crystals grow too large during freezing, they will puncture the cell membrane and the food will leak the intracellular fluid during thawing. Also, the food texture will become unappetising and mushy…

Shelf life determination: The manufacturer’s challenge

Issue 6 2015  •  9 December 2015  •  Carol Zweep, Manager of Packaging, Food and Label Compliance, NSF-GFTC

Food manufacturers face many challenges in providing safe, quality food products in line with customer demands. Consumers expect to purchase high quality, fresh food. There is also a desire for fewer or no food additives or preservatives along with environmental concerns about food wastage. Manufacturers are pressured to reformulate to meet health and clean label demands and to ensure food safety and brand protection. In addition, manufacturers are challenged with maximising and determining shelf life of food products that are exposed to varying conditions in the supply chain. Shelf life touches on all the issues above (consumer trust, safety and quality) and shelf life determination is an essential requirement for food processors. This article discusses factors affecting shelf life, how to determine end of shelf life, how to conduct shelf life testing in a step-by-step approach, and accelerated shelf life testing…
