“…Widaningrum et al (2015) stated that packaging or coating can inhibit respiration rate and suppress fruit softening. Several studies also reported that NP-ZnO -based coatings and packaging are able to delay the decrease in fruit hardness such as jujube (Li et al, 2009), kiwi (Meng et al, 2014) and salaca (Marpaung et al, 2015).…”

Minimally processed jackfruits can usually be found in traditional markets, but the fact found that jackfruit is sold unpackaged and the fruit is not fresh, some have even browned and are infested with flies. Refrigerator is usually applied, but this technology is relatively expensive and not all farmers/traders can afford it. Edible film is an alternative that is easily degraded and decomposed by natural composers plus zinc oxide (ZnO) which is a piezoelectric ceramic that has anti-microbial properties. The purpose of this research was to determine the effect of ZnO concentration on the characteristics of edible films and to determine the best concentration of ZnO and its effect on packaging in jackfruit. Variations in the concentration of ZnO used 0%, 3%, 9% and 12%. Observations on jackfruit were carried out at room temperature. Results showed the higher the concentration of ZnO, the better the ability of edible films with ZnO to maintain the quality and shelf life of jackfruit. Edible film with 12% ZnO was able to extend the shelf life of processed jackfruit for at least 5 days at room temperature .

“…This is because the presence of NP-ZnO in the coating polymer can improve the mechanical properties of the polymer used. coatings were able to reduce weight loss of salak fruit better than controls (Marpaung et al, 2015;Sabarisman et al, 2015). In this research process, jackfruit is stored at room temperature.…”

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.
