ABSTRACT
Retention of vitamin
C before and after pasteurization in some fruit juice namely, orange, Lemon,
Lime and grape pasteurized at different temperatures was investigated. The
juices from the samples were extracted manually, pasteurized at 35C for 30mins
40°C for 25min, 45C for 20mins and so0c for 15mins. The juices were all
analyzed for their vitamin C content by the method of the association of
vitamin chemist. Results revealed that vitamin C concentration is more in
orange juice compared to grape, lemon, and lime juice respectively, in this
order 136.3mg/100g> 122.0mg/lO0g> 74.3mg/100g> 72.8mg/100g and the
rate at which vitamin C is lost during pasteurization depends on the length of
time. Juice should be discouraged from being displayed in hot weather above room
temperature in order to maintain production concentration.
