Pengemasan dengan Plastik Polipropilen dan Lama Penyimpanan terhadap Susut Berat dan Vitamin A Wortel

Abstract

Carrot is a vegetable commodity that is well known by the people of Indonesia and is popular as a source of vitamin A because it contains high carotene compounds (provitamin A) and many benefits for the body, therefore post-harvest must be considered properly. The aim of this research was to determine the effect of carrot packaging with polypropylene plastic stored at low temperature storage (10 ± 5°C). The study was conducted at the Agricultural Technology laboratory, Faculty of Agriculture, Warmadewa University, Denpasar, in March - April 2019 and an analysis of beta carotene (vitamin A) levels was carried out at the Laboratory of the Faculty of Agricultural Technology, Udayana University. This study uses a randomized block design (RBD) consisting of two factors, namely: Factorial I is the thickness of the polypropylene plastic consisting of 3 levels: 0.02 mm, 0.03 mm, 0.04 mm. Factorial II is the storage time which consists of 3 levels: 7 days, 14 days, 21 days. The parameters observed were weight loss, moisture content, carrot vitamin A. The results of research using polypropylene plastic thickness of 0.04 mm suppress heavy shrinkage and loss of vitamin A during low temperature storage for 21 days storage. The thicker polypropylene plastic used tends to be able to maintain the water content of the product, this is related to the permeability of gas and water vapor on the plastic. The value of water vapor permeability on PP packages with a thickness level of 0.04 mm is smaller when compared to packages with a thickness level of 0.02 mm and 0.03 mm
