be used to process milk, cream, ice cream mix, milk concentrates and other dairy products for consumer and in- stitutional markets. Packaging for the product at Nelson Dairy is the aseptic pouch system, the first installation in North America. Excello Pure Pal< equip- ment has also been installed for 'long life' products. While the Nelson Dairy installation currently produces 2,500 litres per hour, systems to 8,000 litres per hour are now under construction and larger units are planned. The system is fully auto- mated, using computer based control for all functions including the DASI process, CIP, standardized blending and product selection. The DASI FreeFallingFilm@)System employs a "Free Falling" principle in which milk is heated as it falls in thin sheets through a steam atmosphere. Because the milk never touches any sur- face while it is heated and is exposed to ultra high temperatures for only a fraction of a second, it retains the natural flavor of pasteurized milk. New Bacterial Growth Analyser Accurate analyses of bacterial growth in blood, urine and food can be made more quickly than ever before with the British-designed Microbiological Growth Analyser. It can analyse blood samples in one day compared with 10 days for the radioactive food method, can precisely tell bacteria growth levels in food within three hours compared with 24 for the conventional method, and can measure antibiotic sensitivity in one working day compared with two or three needed for optical meas- urement.

The recommended intake is an estimate of the amount of a nutrient that meets the requirements of most people within a specific physiological group (age, sex, body size, physical ac- tivity, type of diet).

Thiamin is lowered by 20% to 0.1 mg per 1000 kJ of energy. The values for folacin include all of its forms and not just the free folic acid.
