Studies were made of green plantain behavior when stored under various conditions to develop the best method of prolonging their shelf life without affecting their overall quality and processing characteristics. Freshly harvested green plantains start to ripen in about 7 days, reaching full ripeness 2 days later, when kept under room conditions at temperature of about 85° F. When stored in refrigerated chambers, plantains from the Guayamero and Maricongo cultivara remain green for 12 days, at which time signs of chilling damage begin to appear. However, the quality of plantains stored in these refrigerated chambers at 45° and 55° F. with relative humidities of 86 to 88 percent are definitely affected. At 45° F. a marked hardening of the fruits was observed and at 55° F., signs of false ripening appeared, impairing the quality of the produce. Shelf life of green plantains may be successfully prolonged, however, when thiobendazole-treated fruits are stored in sealed polyethylene bags containing an ethylene absorbent (about 200 g. of Purafil). TBZ was used in a 200-p.p.m. concentration to control mold growth. By using these combined techniques plantains were kept perfectly green for 25 days at room temperature (85° F.) and for 55 days under refrigeration (55° F.). This method had no detrimental effect on the stored fruit, as shown by the sensory evaluations of two processed products prepared from the stored green plantains at various intervals throughout the study. Tasters rated the samples as good or superior to similar products prepared from freshly harvested green fruit.

Jenang, or what is often called dodol, slab, or gelamai, includes dense, chewy, half-processed products. Jenang, which was innovated from chayote, has a relatively short shelf life, which is only able to survive 3-5 days at room temperature (27ºC). Therefore, a good packaging is needed that can extend the shelf life of one of them is edible coating, which is the packaging of edible materials. Edible coating is one of the efforts that can be done to maintain the quality of a food. The purpose of this study was to determine the quality and estimation of chayote with and without edible jenang based on physical, chemical, and microbiological parameters. In this study using the analysis of water content, peroxide numbers, and total microbes and using the edible dip method. From the research it can be seen that the chayote jenang based on physical quality in edible samples can maintain the water content so that the texture remains elastic compared to without edible until the 15th day. Based on the chemical quality in jenang squash with edible, oxidation only occurred after storage on the 22nd day. Microbiological quality in the conjoined pumpkin jenang coated with edible or without edible was overgrown with a total amount of yeast mold ≥300,000 Cfu / g.

Aceh noodle seasoning was made from red chili, red onion, garlic, cardamom, turmeric, ginger, cumin, candlenut, coriander and pepper. All ingredients were mashed and then sauteed in a frying pan with the addition of cooking oil. In the food industry it is necessary to determine the shelf life so the consumers know the quality of the product. Shelf life is the periode of a product from the production process until the product has decreased in quality or is not suitable to consumption. This research was conducted using a semi-empirical accelerated shelf-life testing method with the Arrhenius equation. The estimation of shelf life was determined through the quality change of Aceh noodle seasoning which packed with aluminum foil packaging and stored based on temperature factor (room temperature, 40o C, and 50o C). Each sample was analyzed of thiobarbituric acid test, flavour and descriptif test in duplicate. The results show that Aceh noodle seasoning shelf life based on the critical parameters  stored at room temperature (27-30oC) was 71 days, at 40oC was 49 days, and at 50oC was 35 days.

Peach is a climacteric highly-perishable fruit whose post-harvest preservation relies largely on cold storage. The combination of the last with other technologies allows to extend the shelf life of this product. One alternative is the utilization of salicylic acid, a natural compound involved in many physiological phenomena such as resistance against diseases and ripening. Considering these facts, the objective of the present work was to evaluate the effect of pre-harvest application of salicylic acid solutions on the quality of ‘Chimarrita’ peaches during post-harvest cold storage. The experiment was conducted at the Federal University of Pelotas/RS, in the campus of Capão do Leão/RS - Brazil. The application of salicylic acid solutions was performed by direct pulverization on the fruits, 30 days prior to harvest. The concentrations were: 0,0 (control); 1,0; 1,5; and 2,0 mM. After harvest, the fruits were stored in a cold chamber at 1,0 ± 0,5°C and 85-90% RH, for 30 days. The analyses were performed at the following cold storage periods (plus 2 days at room temperature of 20°C to all treatments, in order to simulate commercialization conditions): 10 (+2) days; 20 (+2) days; e 30 (+2) days. The variables evaluated were: mass loss (%); flesh firmness (N); DA index; color (L, a*, b* and hue angle); wooliness incidence (%); rot incidence (%); total soluble solids (°Brix); pH; titrable acidity (% of organic acids); and ratio. The salicylic acid doses and/or the cold storage periods had significant effects on all the evaluated parameters. For most of the parameters analyzed, the intermediate dosis of 1mM (and also 1,5mM) of salicilic acid showed the most promising results. Therefore, the application of salicylic acid solutions 30 days prior to harvest is a technique which can be combined to cold storage in order to shift the quality and the shelf-life of ‘Chimarrita’ peaches.

The present study evaluated the effect of NPK fertilizer (17:17:17) rates (0, 100, 200, 300 and 400 kg ha-1) on the postharvest quality of field and greenhouse grown pepino melons (Solanum muricatum Ait.) stored at room temperature (15-22°C) and at low temperature (7°C). The study was carried out in randomized complete block design with fruits from the field and greenhouse, five NPK fertilizer rates as treatments and the two storage temperatures replicated three times. Data were collected on percentage fruit weight loss (PWL), total soluble solids (TSS), firmness and shelf life. Results indicated that greenhouse and field grown fruits from the control and plants supplied with 100 kg NPK ha-1 had low PWL at both storage temperatures. Field grown fruits from the control stored at room temperature had the highest TSS and were firmer after 28 days of storage. Field grown fruits not supplied with fertilizer and stored at low temperature had a shelf life of 27 and 26 days in trial one and two respectively. Application of 100 kg NPK ha-1 and storage of pepino melon fruits at low temperature can be used to enhance quality and shelf life.

Kepok bananas are processed bananas that have ABB genotype, the letter B indicates that banana kepok has a stronger resistance to disease and chilling injury in cold temperatures storage. Storage at cold temperatures can extend the shelf life of bananas, because cold temperatures can slow down the respiration and enzymatic processes. The purpose of this study is to observe the effect of storage temperature on quality and shelf life, and to determine optimum storage temperature. The method used is storage temperature at room, 15oC and 10oC until the banana is damaged. The parameters observed were respiration patterns, weight loss, hardness, fruit skin color, total acid, vitamin C, pH, and total soluble solids. The results showed that bananas stored at cold temperatures (10oC and 15oC) can last up to 20 days while at room temperature only lasts for 10 days. Kepok bananas stored at 10oC have not shown symptoms of chilling injury.

<p class="p0">Serabi Solo is a traditional food made from rice flour, coconut milk, sugar, salt, water and other ingridients. Serabi is round, flat and porous. Coconut milk was used to develop serabi's taste making it sweet and savory. However, rancidity can decrease quality of serabi during shelf life. Mold growth also affects food safety of this perishable food. Serabi Solo is developing as gift that has longer shelf life beside flavor and appearance variations. Concrete solutions to inhibit rancidity were matcha green tea because of poliphenol as an antioxidant. Matcha green tea addition and pasteurization improved Serabi Solo quality and inhibited rancidity. Based on previous research, matcha green tea 1% made Serabi shelf life longer (24,66 hours). Other solution was coconut milk pretreatment. According to previous research, lemon juice pH 3 was used in coconut milk with hurdle technique made Serabi Solo has shelf life longer (32 hours). Therefore, this activity was to introduce matcha green tea 1% and lemon juice pH 3 to extend shelf of Serabi Solo in SME Linco's Solo.</p><p class="p0"><strong>Bahasa Indonesia Abstrak</strong>: Kue serabi solo merupakan salah satu makanan tradisional yang terbuat dari tepung beras dan santan. Kue ini bulat, pipih dan berpori-pori. Penambahan santan saat memasak serabi membuat serabi terasa manis dan gurih. Namun, santan dalam serabi selain memberikan rasa gurih juga mudah mengalami kerusakan selama penyimpanan. Munculnya aroma dan rasa tengik yang tidak disukai menyebabkan penurunan kualitas dan daya simpan kue serabi. Selain itu, pertumbuhan kapang juga menjadi masalah keamanan pangan pada serabi. Padahal sebagai produk oleh-oleh, serabi diharapkan memiliki umur simpan lebih panjang selain variasi rasa dan tampilan yang menarik dan kekinian. Solusi aplikatif untuk menghambat ketengikan pada kue serabi solo adalah penggunaan matcha green tea karena mengandung polifenol sebagai antioksidan. Penambahan matcha green tea dan perlakuan pasteurisasi pada santan dapat memperbaiki mutu dan mampu menghambat proses ketengikan sehingga dapat memperpanjang umur simpan kue serabi. Hasil dari penelitian sebelumnya, pada uji ketengikan menunjukkan bahwa kue serabi dengan penambahan matcha green tea konsentrasi 1% memiliki umur simpan selama 24,66 jam. Selain penambahan, matcha green tea, upaya memperpanjang umur simpan serabi yaitu dengan mendesain pretreatment santan. Penelitian sebelumnya menggunakan jenis jeruk dan konsentrasi pH asam sitrat yang paling disukai konsumen dan pengaruh serta lama daya simpan serabi dengan pretreatment santan menggunakan teknik hurdle. Serabi yang paling disukai adalah serabi dengan formula pretreatment santan menggunakan air jeruk lemon dengan pH 3 yang memiliki umur simpan 32 jam. Oleh karena itu, pada kegiatan PkM ini mengaplikasikan matcha green tea 1% dan sari jeruk lemon dengan pH 3 untuk meningkatkan umur simpan serabi terhadap variabel ketengikan di UKM Lincos Solo. </p><div id="gtx-trans" style="position: absolute; left: 23px; top: 207.571px;"> </div>

Four different types of Dahi (Yogurt) were prepared and kept at room and   refrigeration temperatures with different concentrations of potato mash (0, 5, 10 and 15%). These Dahi samples were analyzed for smell and taste, body and consistency, colour, texture and acidity and pH at pre and post storage period. The quality of Dahi deteriorated quickly at room temperature than at refrigeration temperature. With (5%) or without potato mash keeping quality was preserved for up to three days but at refrigeration temperature they were suitable up to 12 days. Addition of 10% and 15% potato mashes were suitable for keeping Dahi up to two days at room temperature while in refrigeration temperature it was acceptable up to ten and eight days, respectively. Preparation of Dahi in incorporating potato mash may be economically feasible without compromising it qualities. DOI: http://dx.doi.org/10.3329/bvet.v29i1.11886 Bangl. vet. 2012.

The investigation was conducted in the Molecular Horticulture Laboratory of Agrotechnology Discipline, Khulna University to develop processed products from jackfruit through their sensory evaluation in order to see their suitability and consumer acceptability. Using variation in sugar contents five preparations of raw jackfruit green pickle, four preparations of rind jelly and bulb jelly, and three preparations of jam, squash and sweet pickles were successfully prepared. Results from sensory evaluation using a seven point hedonic scale to rate for color, taste, flavor, texture and overall acceptability by untrained panelists indicated preparation No. 3 of green pickle, preparation No. 3 and 4 of rind jelly, preparation No. 2 of bulb jelly, jam, squash and sweet pickle scored highest among all the preparations. The storage of these products in normal room temperature showed that produced pickles remain unchanged even after 12 months of storage. But the quality of jam, jelly and squash started to deteriorate after 7 months of storage due to the absence of preservatives. Based on results, it can be concluded that commercial production of the products by using different parts of jackfruit can be taken up and promoted as a small scale income generating activity.J.
