Kajian Penyimpanan Buah Naga (Hylocereus Costaricensis) dalam Kemasan Atmosfer Termodifikasi

Abstract

Modified atmosphere packaging (MAP) is an alternative technologies for foodstuff packaging, distribution and storage which resulting in products with an increased shelf-life. The principle of MAP is modifying the gas inside the packaging by using plastic or film with specific permeability. This technology will be tried to package dragon fruit (Hylocereus costaricensis) to prolong its shelf-life. The procedures are respiration rate measurement, determining O2 and CO2 composition of modified atmosphere packaging, and determining the type of packaging film. There are also observations made include the weight loss, hardness and color changes, total soluble solids, and organoleptic test. The result is respiration rate of dragon fruit at temperature 10°C, 15°C and ambient are 4.15ml/kg.hour CO₂ and 3.95 ml /kg.hour O₂, 9.94 ml/kg.hour CO₂ and 8.75 ml/kg.hour O₂, 16.72 ml/kg.hour CO₂ and 16.72 ml/kg.hour O₂. The composition of the atmosphere that recommended for storage of dragon fruit is 2-4% O₂ and 6-8% CO₂on 10°C and prolong the storage-life until 25 days with stretch film and styrofoam plate which dimension 12cm x 18cm
