Bitter gourd (Momordica charantia Linn.) fruit slices blanched either in 5% NaCl at 100 degreesC far 3 min (HTST) or in a two-stage balnching process in 5% NaCl at 70-80 degreesC for 20 min (LTLT), followed at 100 degreesC fo r 3 min (HTST) was most effective in removing bitterness and maintaining fi rmness of vinegar pickled products. Effect of blanching was significant (p< 0.05) on the acceptability of the products. A product from two-stage blanch ing treatment with 0.1% CaCl2 got the highest scores (7.83-8.17) and was ra ted the best. On storage at 30-32<degrees>C for 32 days, pH stabilised at 3 .17-3.20, ascorbic acid decreased, colour changed from dark green to olive green with no microbial growth.
