Food contact material pictogram (left) on a plastic food container in Hong Kong. Food contact materials or food contacting substances (FCS) [1] [2] are materials that are intended to be in contact with food. These can be things that are quite obvious like a glass or a can for soft drinks as well as machinery in a food factory or a coffee machine.
Nowadays, soda-lime glass is the commonly used variation manufactured from raw materials such as soda ash, limestone, and metal. Due to the structural characteristics of glass, the risk of migration into the food is very limited. Glass is incredibly chemically stable and durable when handled carefully (due to its fragile nature). [34]
Cookware and bakeware is food preparation equipment, such as cooking pots, pans, baking sheets etc. used in kitchens. Cookware is used on a stove or range cooktop, while bakeware is used in an oven. Some utensils are considered both cookware and bakeware. There is a great variety of cookware and bakeware in shape, material, and inside surface.
It can be appreciated that the siloxanes would have low barriers for rotation about the Si−O bonds as a consequence of low steric hindrance. This geometric consideration is the basis of the useful properties of some siloxane-containing materials, such as their low glass transition temperatures.
Care in package design and use is required for proper food safety. [1] A "crisping sleeve" is a device made of paperboard and affixed with a susceptor used both as a rigid container to support the food items within and to focus heat on the foodstuff. [2] They are generally intended for a single use. [3]
Lyotropic main chain LCPs have rigid mesogen cores (such as aromatic rings) in the backbones. [12] This type of LCPs forms liquid crystals due to their rigid chain conformation but not only the aggregation of mesogen cores. Because of the rigid structure, strong solvent is needed to dissolve the lyotropic main chain polymers.
Food technology is a branch of food science that addresses the production, preservation, quality control and research and development of food products. It may also be understood as the science of ensuring that a society is food secure and has access to safe food that meets quality standards.
Bacteria identification and food quality monitoring using biosensors; intelligent, active, and smart food packaging systems; nanoencapsulation of bioactive food compounds are few examples of emerging applications of nanotechnology for the food industry.[2] Nanotechnology can be applied in the production, processing, safety and packaging of food.
