Abstrak.  Salah satu ciri komoditas hortikultura termasuk pepaya adalah sifatnya yang mudah rusak (perishable) seperti mudah busuk dan mudah susut bobotnya karena kulitnya yang tipis dan daging buahnya yang lunak. Dari hasil penelitian kerusakan fisik yang yang terendah terdapat pada alat transportasi kapal cepat dengan perlakuan bahan pengisi kemasan yang menggunakan bahan pengisi daun pisang kering, dan dari hasil uji BNT bahan pengisi yang bagus adalah daun pisang kering, dikarenakan daun pisang kering berbentuk lentur dan suhu dari daun pisang kering tersebut netral. Susut bobot setelah transportasi yang paling sedikit terjadinya kehilangan pada kapal lambat dengan perlakuan tanpa bahan pengisi, hanya sedikit selisih dengan alat transportasi kapal cepat bahan pengisi daun pisang kering.Nilai vitamin C yang tertinggi adalah 11,6 yang diperoleh pada perlakuan kapal cepat dengan bahan pengisi styrofoam. Tingkat kesukaan panelis terhadap rasa dan warna pada perlakuan kapal lambat dengan bahan pengisi styrofoam, sedangkan nilai terendah ada pada perlakuan kapal lambat tanpa bahan pengisi, rasa dan warna sangat berhuhungan sehingga nilai tertinggi terdapat pada perlakuan yang sama dan juga hasil terendah.The Influence of Packaging Fillers on Physical Damage to Papaya Fruits (Carica papaya L.) During Sea TransportAbstract. One characteristic of horticultural commodities including papaya is its perishable nature as it is easy to rot and easily shrinks its weight due to its thin skin and soft flesh. From the result of the research, the lowest physical damage was found in fast ship transportation by the treatment of packing material using dry banana leaf filler, and from the BNT test the good filler was dried banana leaf, due to dry banana leaf-shaped bending and temperature from Dry banana leaves are neutral. Weight loss after transport with the least loss of slow-moving vessels with no filler treatment, only slight difference with the rapid vessel transport filling of dried banana leafs.The highest vitamin C value was 11.6 obtained in the treatment of fast vessels with fillers Styrofoam. The panelist's favorite level of taste and color in the treatment of slow vessels with styrofoam fillers, while the lowest values are in slow ship treatment without fillers, the flavors and colors are highly respected so that the highest value is in the same treatment and also the lowest yield.

O mamão é um dos mais importantes frutos tropicais atualmente cultivados no país e no mundo, apresentando uma excelente fonte de vitaminas A e C, fósforo, cálcio, ferro e potássio, entre outros.  Apenas a polpa do mamão é geralmente consumida, o restante do fruto, casca e sementes, na maioria das vezes é rejeitado. Esses subprodutos podem ser úteis como elementos para estudos e suas utilizações alternativas, tendo como base as características químicas. Dessa forma, este trabalho foi realizado com o objetivo de avaliar o efeito de diferentes temperaturas de secagem no teor de vitamina C em farinha da casca, polpa e semente de mamão (Carica papaya). Os frutos foram adquiridos no mercado local da cidade de Morrinhos-Go, transportados para o laboratório e selecionados quanto ao estádio de maturação e danos físicos, foi aplicada a lavagem com posterior sanitização. O preparo da farinha foi realizado em diferentes temperaturas, 40 °C, 50 ºC e 60 °C por meio de secagem em estufa com circulação de ar. A determinação de vitamina C foi realizada pelo do método titulométrico com iodato de potássio. Nas amostras com aplicação de secagem a 60 ºC, a degradação da vitamina C foi relativamente maior quando comparadas às amostras secas a 40 ºC, as polpas de mamão secas a 40 ºC apresentaram menores teores de vitamina C, quando comparados aos resultados obtidos na aplicação de temperatura de secagem a 50 ºC, inferindo assim que o tempo e a temperatura de secagem influenciaram na degradação do teor de vitamina C. Palavras chave: Carica papaya. Secagem. Farinha. Vitamina C. AbstractPapaya is one of the most important tropical fruits currently cultivated in the country and in the world, presenting an excellent source of vitamins A and C, phosphorus, calcium, iron and potassium among others and fibers. Only the pulp of papaya is usually consumed, the rest of the fruit, peel and seeds, most of the time it is rejected. Such by-products may be useful as elements for studies and their alternative uses, based on the chemical characteristics. The goal of this study was to evaluate the effect of different drying temperatures on the content of vitamin C in the peel, pulp and seed from papaya (Carica papaya). The fruits were purchased in the local market of the city of Morrinhos-Go, transported to the laboratory and selected for maturation stage and physical damage, washing was applied with subsequent sanitization. Flour preparation was performed at different temperatures, 40 °C, 50 °C and 60 °C by drying in an air circulation oven. The determination of vitamin C was carried out using the titration method with potassium iodate. In the samples with drying application at 60 °C, the vitamin C degradation was relatively higher when compared to the dry samples at 40 ° C, the dried papaya pulps at 40 °C presented lower vitamin C contents when compared to the results obtained in the application of drying temperature at 50 °C, thus inferring that the drying time and temperature influenced the degradation of the vitamin C content. Keywords: Carica papaya.

General characteristics of fresh horticultural products like chili, is easily get damaged after harvest. The chili declining quality and loss after harvesting occur due to ongoing respiration process. Hence, the chilies become wither or rot. This damage happens due to physical, microbiological, and physiological influences. Physical damage and yield loss can be caused by packaging uses during storage. The study aimed to determine the effect of packaging use type for Locker Telun Berasap chillies on the weight loss and damage during storage. The treatments were the commonly community packaging use types which consists of: a) polyethylene plastic (PE), b) paper and c) banana leaf. Each treatment was performed two replications and stored at room temperature. Observation parameters during storage were weight loss, and physical, physiological, microbiological damages. The lowest weight loss percentage for 12 days’ storage by PE packaging was 45.5%. The total damage was 30% lower compared to paper and banana leaf packaging. Optimal freshness can be achieved until the 8th day of storage with physical damage only 1.03% on PE packaging. The results of the study showed that the dominant microbiological damage was found in the banana leaf packaging treatment.

Strawberries are an extremely perishable fruit mainly due to their soft texture and sensitivity to fungal infection. Postharvest application of conventional fungicides to fruits is prohibited. As an alternative to fungicides, salicylic acid has been found to enhance disease resistance of horticultural crops. In order to study the effect of salicylic acid as a phenolic compound on the postharvest durability and quality characteristics of strawberry fruit. ‘Gaviota’ strawberries were treated with SA at different concentrations (0, 25, 50 and 100 µlL-1), then stored for 12 days at 4 ˚C and 75 % RH in darkness. Two different methods were applied (spray SA on fruits and paper disk method). Quality attributes such as weight loss, pH, TA, TSS, vitamin C, anthocyanin, calcium, pectin, CAT, POD, PG activity, decay percentage and sensory analyses evaluated every 3 days during storage. Results showed that, treated fruits with SA had lower weight loss, pH, TSS, POD, PG, decay and higher TA, vitamin C, anthocyanin, calcium, pectin, CAT and fruit quality compared with controls. Between two methods of treatment, paper disk method had higher effect on fruit decay and quality compared to spray method and as a general result, caused longer storability.

Abstract The quality of agricultural products can be remotely sensed and enhanced by determining the dielectric properties. This paper studies the dielectric properties of banana leaf and banana peel over the frequency range 1–20 GHz using the open-ended coaxial probe (OCP) method. A new curve fitting model is proposed to characterize the dielectric properties of banana leaf and banana peel. The different moisture content (MC) levels are considered for both banana leaf and banana peel samples and, their dielectric properties are characterized. Further, the banana leaf and banana peel’s measurement data are compared with the data obtained using the proposed model. In addition, Root Mean Square Error (RMSE) and R-squared (R 2) are calculated to validate the performance of the proposed model. In case of banana leaf at 68.26% MC, the dielectric constant achieves the value of R 2 and RMSE of 0.98 and 0.0648, respectively. Similarly, dielectric loss achieves the value of R 2 and RMSE of 0.88 and 0.0795, respectively. Further, for banana peel at 80.89% MC, the dielectric constant achieves the value of R 2 and RMSE of 0.99 and 0.2989, respectively. Similarly, dielectric loss achieves the value of R 2 and RMSE of 0.96 and 0.6132, respectively.

Tomato (Lycopersicon esculentum) is highly perishable and has potential for processing industries in bumper producing seasons in Nepal. The study on judicious use of nitrogen and potassium levels was aimed to explore the quality attributes along with the shelf life of tomato fruits. Three levels of nitrogen comprising 0 kg/ha (N0), 100 kg/ha (N100), 200 kg/ha (N200) and four levels of potassium 0 K2O kg/ha (K0), 80 K2O kg/ha (K80), 160 K2O kg/ha (K160), 240 K2O kg /ha (K240) were used as treatments in randomized complete block design with three replications at Chitwan (Inner Terai) Nepal. Tomatoes at breaker stage were harvested from the field and 10 fruits from each treatment per replication were kept for physiological weight loss, color rating and shelf life in ambient condition (17.5±3 0C and 80.5±6.5 % RH). Fruit quality with respect to physicochemical properties like firmness, TSS, TA, pH and Vitamin C was assessed at the end of shelf life. Higher potassium levels hasten color development and increased TSS, firmness and vitamin C content. Physiological weight loss was greatly reduced and extended shelf life was achieved with 100 kg N/ha and 240 kg K2O/ha.

Seal packaging of individual fruits of Dancy mandarin ( Citrus reticulata) with polyolefin (0.019 mm) and PVC (0.025 mm) significantly delayed their deterioration, and maintained firmer fruits with bet ter appearance than non-sealed fruits. The films were applied to fruits that had received conventional treatments of washing and disinfection, after which the fruits were stored with non-sealed fruits under refrigeration conditions (5 and 10 °C) during eight weeks plus six days at 20 °C. The results showed that the weight loss and deformation were significantly reduced by the effect of plastic films, at both storage temperatures. Furthermore, significant reductions in the internal atmosphere (CO, content) and ethanol content were observed in sealed fruits. In the sensory evaluation, the juice of sealed fruits showed a fresh flavor at the end of storage, whereas the juice of non-sealed fruits held at 10 °C developed off-flavors. The ripening index (°Brix/acidity ratio) increased significantly only in sealed fruits held at 10°C. The color index was not significantly modified by the effect of plastic films. However, the vitamin C content was significantly lower in sealed fruits at both storage temperatures.
