Identification of Banana Quality (Musa paradisiaca Var. Sapientum L.) Through the Using of Coconut Shell Charcoal and Potassium Permanganat as Absorber

Abstract

One of the most frequently encountered problems in handling bananas is the ease of it characteristic to decay so they cannot be stored longer. Thus a technology is needed to increase the shelf life of banana. The use an absorber from coconut shell charcoal which is applied with potassium permanganate is a method that can be used. In this study the effectiveness of the absorber was tested using gas chromatography. The results obtained show us that the ethylene concentration can be pushed by the addition the number of the absorber. The treatment carried out is by compare it at two temperatures. Where at a temperature of 13 0C, the ethylene concentration is about 102.78 ppm for an absorber of 10 g. At 20 g it is 95.13 ppm. At 30 g it is 64.23 ppm and at 40 g is 65.85 ppm. At a temperature of 28 0C in the 8th hour the ethylene concentration was 104.30 ppm for 10 g absorber. At 20 g, it is 101.12 ppm. At 30 g is 89.22 ppm. At 40 g, it is 64.20 ppm. Absorber treatment affects ethylene production, and slows the physical and chemical processes of Raja banana which is characterized by green colouruntil the end of storage time and retained hardness, high starch content, low sugar content and small amount weight loss. generally, the treatment of ethylene potassium absorbent material greatly influences the maturation effect, by suppressing ethylene production and maintains the green color, texture and aroma of Raja banana within 15 days at 28 0C and 45 days at 13 0C.
