Starch and derived products- Heavy metals content- Part 2: Determination of mercury content by atomic absorption spectrometry

This part of ISO 11212 specifies a method for the determination of the mercury content of starch, including derivatives and by-products, by atomic absorption spectrometry with cold-vapour generation. The cold-vapour generators currently available use very different techniques; it is thus impossible to propose a comprehensive method likely to ensure the attainment of satisfactory results on all types of apparatus. Each analyst should therefore optimize the conditions of use of his/her own apparatus on the basis of general or particular instructions.

Food processing machinery. Vegetable peelers. Safety and hygiene requirements

1.1 This European standard specifies the safety and hygiene requirements for the design and manufacture of vegetable peelers used in the commercial and institutional catering industry, and in food shops. The machines concerned by this standard are designed to peel different sorts of vegetables and tubers such as potatoes, carrots, salsify, turnips, celery and onions. The standard is limited to machines where the maximum capacity is 50 kg. The machines are not intended to be moved during operation. The rotating plate mixes the product under appropriate conditions so that the desired operation is carried out on the entire load. This operation can be: - the abrading of the surface of the vegetable or tuber; - the cutting of fine particles of skin if the fitting is of the blade-type; - grating, an operation which is similar to abrading; - scraping or cleaning with a brush, rubber coating or cast iron surface. Machines subject to this standard use water circulation to carry waste to the waste outlet. The underside of the plate is sometimes designed with raised parts which speed up the discharge of the waste water. This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, removal of food blockages, feeding, changing the tools, maintenance and decommissioning of the machine. Machines covered by this standard are not intended to be cleaned by high pressure water jets. 1.2 This European standard does not apply to domestic machines.
