Abstract

Fresh (i) mustard greens (Brassica campestris var. Sarson), (ii) spinach beet (Beta vulgaris), (iii) mint (Mentha spicata) and (iv) coriander leaves (Coriandrum sativum) were washed, blanched in 2% sodium carbonate solution at 79.4 degree C for 5 min, cooled in water, drained on Al perforated trays for 10 min, dried in a hot air cabinet at 62.8-68.3 degree C for 7-8 h, cooled to room temp., sealed in high- or low-density polyethylene bags or paper-Al-polyethylene laminates and stored at room temp. for 0-4 months (8 months for (i)). Dried product yields were 8.7, 6.2, 7.0 and 8.3% for (i)-(iv) respectively, with final moisture contents of 6.0, 3.5, 4.8 and 3.5%. On storage the chlorophyll content decreased to some extent, but beta-carotene did not. The reconstituted products had good consistency, colour and flavour.
