Jackfruit is the most popular tropical fruit with high nutritional value. It is the largest edible fruit in earth. Jackfruit pulp is eaten fresh and used in fruit salads (Bose, 1985). But jackfruit seeds are less popular as vegetable and are eaten when boiled or roasted. These are believed to be digested with difficulty (Siddappa, 1957). The nutrient composition of jackfruit seed is similar to that of grains. The seeds are rich source of carbohydrates and proteins and good source of fiber and vitamins (Rahman et al., 1995). The nutritional composition of seeds can be determined by proximate analysis and mineral quantification (Jagadeesh et al., 2007).
Proximate analysis divides the food into six fractions as moisture, ash, crude protein, crude fat, crude fibre and nitrogen-free extractives (Abedin et al., 2012). Among the nutrients, protein plays a significant role in human body. Next to water, protein is the major component of body tissues (Lukaski, 1987). It is the essential nutrient for growth. In the human body, proteins are broken down into amino acids which are used as precursors to nucleic acids, co-enzymes, hormones, immune response, cellular repair, and other molecules essential for life. Jackfruit seed protein contains both essential and non-essential amino acids which impart their specific function in a great extent to human body (Elango, 2009).
