An experiment was conducted to standardize the predrying treatments with minimum loss to physicochemical characteristics of green peas (Pisum sativum L.) cv. Lincoln during drying process. In this study, moisture content (73%), TSS (15oB), chlorophyll content (28mg/100g) and ascorbic acid (54mg/100g) were recorded in green peas. Different predrying treatments used in this study for quality preservation of peas were T0, T1 and T2. From this study, it was concluded that Na2CO3, NaCl and sugars were responsible for the preservation of green color/ chlorophyll in peas during drying. On the basis of sensory evaluation T2 was found best among all because maximum green color was retained in this treatment. Therefore, it was further selected for physico-chemical analysis After drying there was decrease in moisture content (4%), chlorophyll content (17mg/100g) and ascorbic acid content (37.6mg /100g) while increase in TSS (22oB), reducing sugars (8.3%) and total sugars (20%) of peas. A rehydration ratio of 3:1 was observed for this treatment. This is a low cost technology for preservation of quality of peas. Dried peas can further be utilized for the preparation of various value added instant products round the year.

Drying is an important process in the preservation of antioxidants in medicinal plants. In this study, leaves of Phyla nodiflora, or commonly known as frog fruit, were dried using convective drying (CD) at 40, 50, and 60 °C; vacuum-microwave drying (VMD) at 6, 9, and 12 W/g; and convective pre-drying followed by vacuum-microwave finish drying (CPD–VMFD) at 50 °C and 9 W/g. Drying kinetics of P. nodiflora leaves was modelled, and the influences of drying methods on the antioxidant activity, total phenolic content, volatile and phytosterol contents, energy consumption, water activity, and color properties were determined. Results showed that drying kinetics was best described by modified Page model. VMD achieved highest drying rate, whereas VMFD considerably reduced the drying time of CD from 240 min to 105 min. CPD–VMFD was the best option to dry P. nodiflora in terms of retaining volatiles and phytosterols, with lower energy consumption than CD. Meanwhile, VMD at 6 W/g produced samples with the highest antioxidant activity with 2,2′-Azinobis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and ferric reducing antioxidant power (FRAP) value of 11.00 and 15.99 µM Trolox/100 g dw, respectively.
