Effect of various coatings on the chemical changes of different pineapple cultivars (N36 and Gandul) at low temperature storage

The chemical changes in N36 and Gandul pineapples stored at 10 ± 1 °C; 85–88% RH and the effects of various surface coatings (palm oil, liquid paraffin, Semperfresh) were examined by monitoring fruit total soluble solids (TSS), titratable acidity (TA), sugar-acid ratios (TSS:TA), pH and individual s...
