Evaluation of amino acid profile of jackfruit (Artocarpus heterophyllus) seed

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).

About Md. Shafiul Islam

I have been working as an Assistant Professor since May 26, 2015.My research profile lies at the interface of biomaterial science, life sciences and engineering. I am particularly interested in the design of bionanocomposite materials for relevant clinical applications, e.g. in the context of fabricating and testing biocomposite materials to study the biocompatibility with human body to repair bone tissue. I joined as a lecturer at Noakahli Science and Technology University in May 26,2013. During my working as a Lecturer, I did research on waste water treatment. In connection to this, I applied nanotechnology to treat water as well as waste water. Prior to joining the Noakhali Science and Technology University , I joined as a Scientific Officer in Drug & Toxins Lab as well as Polymer Chemistry Lab at Bangladesh Council of Scientific & Industrial Research (BCSIR).Before doing scientific works, I did M.S. thesis work in the Institute of Polymer & Radiation Technology. I completed my undergraduate studies in Applied Chemistry & Chemical Engineering ( University of Dhaka, Bangladesh) and gained my M.S. in the same department, under the supervision of Professor Dr. Mohammed Mizanur Rahman (University of Dhaka, Bangladesh), where he investigated the effect of reinforcement of nano-materials into bio-polymer composite, morphology and the effect of bacteria in the bio-composite. . I achieved Dean's Award in recognition of my excellent academic and oerall performance in B.Sc. In Bangladesh,I was shortlisted for National Science & Technology (NST) Fellowship and was successful in securing funding from Ministry of Science & Technology, in collaboration with Professor Dr.Mohammed Mizanur Rahman, University of Dhaka, towards the manufacture of medical devices that are resistant to microbial colonization. I have authored 6 research papers and 1 conference paper (h-index: 2).
