    In recent years, there has been a noticeable rise in the importance of snack items in diets, particularly among children and adolescents who enjoy them socially with friends. Chips, commonly produced through frying, have garnered significant popularity. This study aimed to assess the quality of fried coconut chips of thickness 0.5 mm and 1.4 mm, made using both sunflower oil and coconut oil. Deep frying was conducted at 160 °C for both types of oil. The findings indicated that coconut oil-fried chips, regardless of thickness, exhibited superior sensory attributes (i.e. appearance, colour, crispiness and flavour). All sensory attributes (except appearance) were rated the highest for coconut oil fried chips. The biochemical properties of chips fried in both oils were largely similar, yet coconut oil-fried chips displayed slightly better characteristics compared to their counterparts. For instance, the 0.5 mm thick coconut oil-fried chips were noted for their improved protein content and fat content, leading to a higher overall acceptability of the 0.5 mm thickness.

    Impact of Slice Thickness and Baking Temperature on the Physicochemical Quality and Nutritional Properties of Newly Developed Baked Coconut Chips

    Due to rising health concerns, consumers are increasingly inclined toward reduced-fat products, which have driven the need for nutritious alternatives through modifications in recipes and production processes. Despite the growing popularity of coconut-based products, there is limited research on baked coconut chips, particularly regarding the effects of baking temperatures and product thicknesses. This study addresses this gap by developing baked coconut chips samples (BCSs) as a healthier alternative to traditional fried chips. Baking experiments were conducted at temperatures of 140°C, 160°C, and 180°C, with 160°C identified as optimal for balancing processing time and product quality. The study also compared baked coconut chips with those that were dried and then baked (dried baked coconut chips samples [DBCS]). Among the trials, the 0.5-mm-thick coconut chips baked at 160°C exhibited favorable sensory attributes and notable biochemical properties, including 3.13% moisture content, 1.13% ash, 40.49% fat, and significant antioxidant activity.
