Abstract

Fruit slicing is a type of minimum food preparation, with sliced apples being a popular example. To preserve fruit, edible coatings, generally consisting of pectin, are often utilized. Pectin from jackfruit (Artocarpus heterophyllus) skin can be used for this purpose, since the production of the fruit is abundance. The physicochemical and organoleptic characteristics of jackfruit peel pectin were investigated using the Microwave-Assisted Extraction (MAE) technique. The flavor and texture of sliced apples were unaffected by edible coatings produced from jackfruit peel pectin. The moisture content of EC jackfruit skin 3% was 24.23% and the thickness was 1.4 mm, whereas the moisture content of EC jackfruit skin 5% was 21.99% and the thickness was 1.51 mm. WVTR results revealed that EC jackfruit skin 3% and 5% increase in weight by 0.005 g/m2 hour and 0.004 g/m2 hour, respectively. EC jackfruit skin 3% had a L* value of -15.6 and a BI value of 47.64 in the enzymatic browning test, whereas EC jackfruit skin 5% had a L* value of -13.44 and a BI value of 46.68. According to the antimicrobial activity test, 3% jackfruit peel EC did not generate an inhibition zone on E. coli and S. aureus bacteria, however 5% jackfruit peel EC formed a 1.92 mm inhibition zone on E. coli bacteria, which is lower than minimum standard of inhibition zone. EC of jackfruit peel 3% and 5% did not affect the organoleptic properties of sliced apples.
