Abstract

Abstract: The genus Kadsura comprises woody vine plants belonging to the family Schisandraceae . Species are found mostly in Northern Thailand and widely consumed by the local population. Occurrences of these wild fruits are rare as they only grow naturally in forest areas. Nutritive values of Kadsura spp. remain unclear, leading to improper management for food applications. Nutritional composition of Kadsura spp. was evaluated to promote sustainable conservation. Nutritive values in different fruits parts (exocarp, mesocarp, seed and core) of two Kadsura species as Kadsura coccinea (Lem.) A.C. Sm. and Kadsura heteroclita (Roxb.) Craib, from Chiang Rai Province, Thailand were assessed. When comparing nutritional contents based on per 100 g dry weight, results suggested that K. coccinea exhibited higher carbohydrate (1–2 times), sugar (1–2 times) and vitamin C (3–4 times) contents than K. heteroclita, while the latter possessed higher fat (1–2 times), protein (1.6–1.9 times), and dietary fiber (1.5–1.8 times) contents. Considering each fruit part, the mesocarp (the only edible fruit part) and exocarp of both species provided high dietary fiber (11.6–20.9% recommended dietary fiber) and vitamin C (as high as 73% recommended per day) but were low in energy (30–40 kcal/100 g fresh weight), protein (0.6–1.2% recommended per day), fat (0.5–1.8% recommended per day) and sugar (2.4–5.4% recommended per day). Interestingly, seed contained higher energy (1–2 times), protein (2–3 times) and fat (4–50 times) than the other fruit parts. Results support the potential consumption of Kadsura spp. as a healthy fruit that can be used for future food applications. Seed and exocarp from Kadsura spp. also showed potential for new product development. Abstract : Food analysis, Nutrition, Kadsura coccinea (Lem.) A.C. Sm., Kadsura heteroclita (Roxb.)
