Questioning if testing only the inner food contact layer of Food & Beverage hoses was enough to ensure the safety of the consumer, Saint-Gobain examined the compliance of a multilayered hose as a whole rather than only its inner layer in the white paper Are Hoses Used for Food and Beverage Transfer Applications Really Safe for Consumers?
The food and beverage processing industry uses a variety of hoses to transfer liquids and foods from tank to tank from pipes to tanks and trucks and in various loading and transfer applications.
To achieve the desired performance, theses hoses, which are made from plastics, rubber, fluoropolymers and/or silicone materials, are commonly constructed with a relatively complicated structure of several layers. Common structures include an inner liner (in direct contact with food), one or more reinforcement layers, and an outer jacket layer (to reduce wear and tear), sometimes resulting in upwards of 7 or more layers.
These hoses are regulated by the FDA, as chemicals from the food contact layer could migrate into the food during the fluid transfer process and adulterate the food and/or pose adverse health risks.
