The Difference

Melon is a type of fruit that has a high water content. High water content causes limited fruit storage, therefore it is necessary to preserve it to maintain the freshness of the melon. One method that can maintain the freshness of the fruit is edible coating. The purpose of this study was to determine the characteristics of organolepic melons given starch-based edible coatings from several types of tubers, namely cassava, canna, and lesser yam. This study used factorial Completely Randomized Design (CRD) with two factors. The first factor is the difference in CMC with a concentration of 1% and 1.5%. The second factor is the difference in glycerol with a concentration of 1% and 3%. The results of the study based on the ANOVA test showed that the type of starch treatment and the concentration between treatments did not have a significant effect on the texture, color, and aftertaste of the melon, but significantly affected the taste and aroma of the melon. So it can be concluded that from all edible coating formulations, panelists preferred the PS I formulation (cassava starch) with 1% CMC concentration and 1% glycerol.Keywords: cassava, canna, edible coating, lesser yam, melons

Initial Storage

The species Eugenia stictopetala, known as “cambucá” or dog-tongue, is found in areas of Cerrado and produces fruits in the form of drupe, black when mature and much consumed by the fauna. Despite its potential for use, there is no information about its germination processes and for this reason, the objective of this work was to evaluate its germination and seedling formation at different temperatures, besides its germination after initial storage. Newly collected seeds from the Cerrado area were evaluated at six temperatures (20, 25, 30, 35, 20-30 and 25-35 °C) and after 35 days of storage in different environmental conditions in a completely randomized design. The results indicated that the seeds have a high water content and the temperature of 30 °C being the most suitable for germination and seedling formation. After storage, loss of water content occurs, leading to a reduction in germination rates, indicating a characteristic of recalcitrant seeds.

The practice of burning and stockpiling to reduce wood waste from the wood processing industry is not in line with the demands of clean production, environmentally friendly and sustainable industries. Pyrolysis technology can be used to produce bioenergy from wood waste. The temperature and the time of the pyrolysis process, the water content of materials, and the content of different yields between types of wood waste affect the bioenergy products produced. This study was aimed at determining the effect of wood waste form and condition on the quality and quantity of liquid smoke, tar, and charcoal. A Completely Randomized Design with two factors of treatments, i.e., waste forms and the drying process, was applied in this research. The results showed that the condition and shape of the material affect the volume of liquid smoke and the weight of the charcoal produced. The condition of the material without drying with high water content and the shape of the chunks produce more liquid smoke with an average yield of 191.14 mL and 186.37 mL, while the charcoal produced is higher in the condition of the material with drying and shaved form at 125.83 g and 115.62 g. The results of the test characteristics of grade 1 and 2 distillation liquid smoke meet the Japanese liquid smoke quality standards with phenol levels in the range of 26.66-35.94 mg GAE/mL sample and acidity levels of 16.91-58.9%.

Edible film made up of modified tapioca was used to wrap tempeh and its shelf life estimation was determined. The edible films must be capable of evenly aerating and maintaining moisture without causing condensation in order mycelium to be able to grow and produce high-quality tempeh. The experiment was carried out in completely randomized design with two main factors of storage temperature and time. An accelerated shelf life test at 17oC, 27oC, and 37oC with an Arrhenius model was used to calculate the shelf life, and water content was used as quality parameter indicator. The result showed that modified-tapioca based edible film made from fermentation of tapioca by Saccharomyces cerevisiae was characterized as having elongation of 11.40 %, tensile strength of 408.37 MPa, thickness of 0.88 mm and WVTR of 12.60 g/m2/h. Rate constant of water content decrease in edible film wrapped tempeh based on Arrhenius model was 0.3832 % day-1 and Ea was 10.296 kkal/gmol, while that of in PP-plastic wrapped tempeh was 0.3831% day-1 and Ea was 9.998 kkal/gmol. The shelf life of edible film wrapped tempeh was 9.39 days at 27oC, 5.18 days at 27oC, and 2.96 days at 37oC, while shelf life of PP-plastic wrapped tempeh was 8.64 days at 17oC, 4.85 days at 27 oC, and 2.82 days at 37oC. Therefore, it can be concluded that modified tapioca based edible film increased the shelf life of tempeh.

Maize is one of the important staple foods for people in Timor, East Nusa Tenggara Province, Indonesia. Subsistent farmers store the maize for their own consumption until the next harvest season, for seed and feed.  However, high initial water content of the kernel due to improper drying prior storage initiate serious damage and losses during the maize storage.  High water content promotes the growth of fungi and insects, and increase respiration rate, resulting in rapid deterioration of maize. The purpose of this study was to determine the initial moisture content that might minimize damage and losses of maize in the farmers’ storage, and to study the effects of some plant materials that are used to smoke corns before storage. The experiment was initiated by sun-drying the harvested corncobs for 0, 2, 4, 6, 8, and 10 days (6 hours a day). This experiment was designed using Completely Randomized Design with 6 treatments and 3 replications. Dried corncobs were stored in the farmer’s storage for 4 months. The effects of maize kernels’ initial water content on the development of water content in kernels; the percentage of damaged kernels; and the species of pathogen and insects were investigated during storage with 2-week intervals.  The results demonstrated that drying the corncobs prior storage for 10 days, resulting in 12.96% of water content, significantly decreased the percentage of seed damage to 6.5%, as compared to without drying process which resulted  in 63%.  Aspergillus flavus, Fusarium sp., and Penicillium sp were found to be the main pathogen during storage.  There are no insect pests found during the storage.

Red Snappers contain high content protein and water which makes them highly perishable. However, they are widely processed into the fillet. One of the disadvantages of filleting is the short shelf life due to the high water content turning the fillets into an ideal media for bacteria. The edible coating protects the meat from perishability by reducing the water vapor, aroma, and lipid migration. One of the potential protein sources for coating is gelatin. The essential oil content that has a role in inhibiting bacterial growth is citronellal. The present study aimed to determine the effects of adding Kaffir limes (Citrus hystrix) leaf essential oil to a gelatin coating on the shelf life of red snappers’ fillet. An experiment was conducted using a completely randomized design with four treatment groups based on the concentration of Citrus hystrix essential oil and five replications (n = 3 per group). In this regard, the treatments were named P0 (0% of Citrus hystrix), P1 (1% of Citrus hystrix), P2 (1.5% of Citrus hystrix), and P3 (2% of Citrus hystrix). The investigated parameters included total plate count, sensory quality, and acidity. Data analysis was performed using ANOVA followed by Duncan’s multiple range test. The results showed that the addition of 1.5% and 2% Citrus hystrix essential oil decreased the number of bacteria, and led to a higher sensory quality. In conclusion, The addition of Citrus hystrix essential oil in the gelatin-coating process can be used as a method of processing the fishery products to extend the shelf life of red snappers’ fillet at room temperature and inhibit bacterial growth.

This experiment was conducted to observe the postharvest behaviors of litchi for using low temperature (4 °C) and polypropylene (PP) bags of different thickness. The two-factor experiment was conducted in a completely randomized design with three replications. Total 8 treatments are implemented in this study. The experiment consisted of two factors: Factor A: Temperature (T1: Ambient temperature, T2: 4ºC temperature) and Factor B: Polypropylene bag (P1: unwrapped, P2: 50µ PP bag, P3: 75µ PP bag, P4: 100µ PP bag. In case of low temperature (4 °C), litchi retained its 50% color at 10th days of storage, highest shelf life (21.33 days), highest moister content (83.3%) & highest amount of vitamin C (35.61 mg/100g) were found at 3rd day of storage. In case of different thickness of polypropylene bags, litchi kept in 75µ PP bags retained its 100% color up to 4th day of storage, shelf life (16.34 days), maximum moister content (83.14%) & maximum amount of vitamin C (35.78 mg/100g) were found at 3rd day of storage. It can be possible to save a large amount of litchi fruits every year from postharvest decay by using low temperature (4 °C) and 75µ PP bag.

The high water content in dragon fruit causes the fruit to be easily damaged, therefore it needs to be processed to reduce the amount of loss, including making it into jam. In addition, processing dragon fruit into various processed products also aims to overcome the problem of excess production when the harvest season arrives. The aim of this research was to obtain the ratio of dragon-sugar fruit which gave the best influence on the physical, chemical and organoleptic characteristics of jam. The study used a completely randomized design (CRD) for the analysis of physical parameters of jam (softness) and chemical jam (water content, total dissolved solids, anthocyanin and vitamin C levels). Randomized Group Design (RBD) for analysis of organoleptic test parameters (color, texture, taste and preference). As a treatment, it is the ratio of dragon-sugar, which consists of five levels of treatment, namely P1 = dragon fruit 450 g: granulated sugar 550 g, P2 = dragon fruit 500 g: granulated sugar 500 g, P3 = dragon fruit 550 g: sugar 450 g, P4 = dragon fruit 600 g: granulated sugar 400 g, P5 = dragon fruit 650 g: granulated sugar 350 g. Each treatment was repeated 3 times so that there were 15 experimental units. The data obtained were analyzed using F test 0.01 and 0.05. If the treatment has a significant or very real effect, then proceed with the BNJ test at tararf 0.01 and 0.05. The results showed that treatment P4 (600: 400 b / b dragon-sugar ratio) gave the best influence on the physical, chemical and organoleptic characteristics of dragon fruit jam. This treatment can reduce the use of sugar by 15 percent from the standard use of sugar in making jam.
