Abstract

Effect of Number of Fruits and Type of Packaging on Physical, Chemical Properties and Shelf Life of Tomato Fruit (Lycopersicum esculentum Mill.) The demand for tomatoes increases along with the increase in economic growth and population. Efforts to maintain the quality of tomatoes are to delay ripening using various plastic packaging. This study aims to determine the effect of the right amount of fruit in the packaging and determine the suitable packaging in maintaining the physical, chemical and shelf life of tomatoes. The research was carried out from December 2020 to January 2021 at the Plant Breeding and Seed Laboratory, Faculty of Agriculture, Udayana University, Jl. PB. Sudirman, Denpasar. The experimental design used was a factorial completely randomized design (CRD) with 4 replications and 2 treatment factors so that 24 experimental units were obtained. The 2 treatment factors were as follows: packaging treatment (K) consisted of three treatments K0 = Control (without packaging), K1 = Polypropylene (PP) packaging, K2 = Polyethylene (PE) packaging and number of fruit (T) consisted of two treatments T1 = 3 pieces in a pack, T2 = 4 pieces in a pack. The results showed that the use of polypropylene packaging (K1) and the use of 3 packaged pieces (T1) were able to extend the shelf life of up to 22.75 days, compared to the polyethylene packaging type (K2). The smallest weight loss was found in the treatment of polypropylene packaging type (K1) at 4 Hsp which reached 0.05%. Treatment of the type of polypropylene packaging (K1) showed a low respiration rate at 4 Hsp which reached 22.88 mg CO2/kg/hour. The treatment of polypropylene packaging type (K1) showed the highest hardness level at 4 Hsp, namely 8.40 mm/100/gram/second. The results showed that the number of fruits per package had an effect on weight loss, respiration rate, and shelf life of tomatoes.

Abstract

The Effect of Chlorine Concentration and Tomato Packaging Type on Physical and Chemical Changes during Storage in Tomatoes Plants (Lycopersicum esculentum Mill.) Tomatoes are one of the important commodities that are vulnerable to contamination by various kinds of microorganisms. The thing that can overcome contamination is by washing and packaging. The chlorine compound that is most often used as a sanitizer is hypochlorite. The type of sanitizer used in this study was sodium hypochlorite (NaOCl). Packaging protects quality and sanitation so that consumers receive tomatoes fresher and quality is guaranteed, packaging should not interfere with the process of heat release from respiration. The type of packaging used in this study was LDPE plastic film and white stretch film (WSF). The design used in this study was a completely randomized design (CRD) with two factors and each combination was repeated three times, so that there were 36 experimental units. The first factor is the treatment of chlorine solution concentrations consisting of four levels: without chlorine solution, concentration of 100 ppm, concentration of 200 ppm, concentration of 300 ppm. The second factor is packaging with 3 levels of without packaging, packed with LDPE plastic film, packed with white stretch film (WSF). The results of this study indicate that the combination of washing using chlorine solution and the best packaging slows the physicochemical changes based on vitamin C variables where the decrease in fruit acid levels is shown in the 200 ppm chlorine concentration and packaged with white stretch film (WSF) treatment.
