摘要

Prepared garlic slices of 2.3 mm thickness divided into six lots for experimental study were dried at six different temperature regimes viz., 40 ℃ 45 ℃, 50 ℃, 55 ℃, 60 ℃ and 65 ℃, respectively, in a hot air cabinet drier to study the effect of various air drying temperatures on quality parameters of garlic after dehydration and after a storage period of 4 months. Dehydration at 65 ℃ (T_6) resulted in the shortest drying run duration of 337.67 minutes and least product moisture content of 4.38 % after dehydration when compared to other treatments and even after 4 months of storage (8.21 %). Treatment T_6 (65 ℃), in terms of biochemical attributes, was also found to be quite acceptable with significantly higher carbohydrate content (69.06 g/ 100 g), proteins (14.85 g/ 100 g), ascorbic acid (5.50 mg/ 100 g), volatile oil percentage (0.323) and low browning index scores (0.045) after dehydration and even after a storage period of 4 months (carbohydrate content; 67.12 g/ 100 g, proteins; 11.21 g/ 100 g, ascorbic acid; 5.50 mg/ 100 g, volatile oil percentage; 0.300 and browning index; 0.065). In terms of sensory quality treatment, T_6 (65 ℃) was superior with an overall acceptability score of 8 after dehydration and 7 after a storage period of 4 months.
