Abstract

Leaf protein concentrate (LPC) is a cheap and vegetarian source of high-quality protein that can be used for dietary enrichment in various food products. The aim of this study was to compare different plants for preparation of LPC. It was found that LPC yield for curry leaves, drumstick leaves and tobacco leaves were 1.64±0.40, 6.60±0.29 and 4.32±0.17 %, respectively. Crude protein content of drumstick and tobacco leaves were 33.01± 2.48 % and 63.72± 2.99 % respectively. Tobacco leaves were identified as best source of LPC and were taken up for further nutritional evaluation. The moisture, total ash, crude protein, fat, crude fibre, carbohydrate and physiological energy value of fresh tobacco leaves were 75.38%, 3.45%, 10.39%, 0.28%, 4.13%, 6.37% and 69.56 kcal/100g, respectively. The moisture, total ash, crude protein, fat, crude fibre, carbohydrate and physiological energy value of tobacco LPC was 9.4%, 6.16%, 62.34%, 8%, 8.7%, 5.4% and 342.96 kcal/100g respectively.
