Food contact materials (FCMs) comprise a broad and complex area, using many different types of materials and articles, as well as many different chemical substances such as additives in the materials and articles. The intent of packaging is to maintain its function of protecting the integrity, quality, freshness and safety…


Screening of acrylamide contents in potato crisps using VIS and NIR technology

13 May 2011 | By Vegard H. Segtnan and Svein H. Knutsen, Nofima AS, The Norwegian Institute of Food, Fisheries and Aquaculture Research

Acrylamide is considered a potential carcinogen and is present at elevated concentrations in different types of heat-treated foods. It is formed during baking, frying and roasting of raw materials from plant origin, particularly potatoes and cereals. Acrylamide is one of the reaction products in the Maillard reaction between the acrylamide…


Overview of food preservation technologies
