panel of judges to select the best beverage. Recodan and Supercol applied @ 0.2-0.3% gave inferior-qual ity bever-
ages, while Grindsted's Gelodan and Givaudan's stabilizer No. 76084-72 gave acceptable beverages. The best formu-
lation wa. prepared by using 13% cane-sugar, 3% apple pulp, 2% SMP, 0.3% Givaudan's stabilizer, 0.2% citric acid,
0.02% sodium citrate, 0.01 % potassium sorbate, 0.07% pineapple flavour, colour as desired and made volume to
100% with water. This was manufactured on a UHT plant by direct steam-injection technique at 144°C ancl packed
