Influence of Mica Packaging Container Sizes on Quality and ShelfLife of Strawberry (Fragaria sp.). This study aimed to determine the effect of plastic mica container size with a total of 15 pieces of packaging and determined the best treatment for the shelf life of strawberries (Fragaria sp). This study useds a complete randomized design methodology (CRD) with one treatment, namely the type of plastic mica container size with various types of packaging types as follows: type 1 (K1), type 2 (K2), type 3 (K3) and number 15 fruit packs. The observed variables were weight loss, hardness level, shelf life, organoleptic test, respiration rate and vitamin C. The size of the packaging containers affected the physico-chemical changes in the strawberries. The treatment influenced the physico-chemical changes in the strawberries, such as the rate of respiration and vitamin C levels. The best packaging size was the smallest size (K1 ) K2 and K3 packaging container sizes. This is indicated by the lowest weight loss variable, with the value of 0.20%, the lowest value of respiration rate (20.61 CO2/ kg/hour), the highest vitamin C  content (72.89 mg/100g), while in the organoleptic test, the smallest container size resulted in the highest score in fruit colour, container size has a score highest in the observation of fruit color, fruit appearance and fruit aroma. Observation of the shelf life of strawberries showed that the container size of K1 (the smallest) had an average shelf life better than K2 and K3.  K1 container size produced a shelf life average of 4 days while K2 container size produce a shelf life average of 3,4 days. The shortest shelf life average was recorded in the K3 container size with a value of 3,2 days. It is concluded that the shelf life of strawberries in a packaging container at a temperature of 28-30ºC can be as long as 4 days.

Tomato was classified as a climacteric fruit with a fast ripening period andthen followed by the increase of fruit softening. The inhibition of fruit softening was needed to maintain the quality and shelf life of the fruit. One of the way to inhibit the tomatoes softening was calcium application. However, the best concentration and timing of calcium application for tomato was still limited. The aimed of research was to determine the best combination of concentration and time of application of calcium chloride (CaCl2) to the physicochemical of tomato. Experiment was arranged in factorial completely randomized design (CRD) with two factors and three replications. First factor was concentration of CaCl2 which consisted of 5 levels (0 M; 0.3 M; 0.6 M; 0.9 M; 1.2 M), while the second factor was application time of CaCl2 (pre- and post-harvesting). The results showed that there was no interaction between concentration and application time of CaCl2 to the physicochemical of tomatoes. Treatment of CaCl2 1.2 M could increased fruit calcium content, inhibited weight loss and fruit softness, increased total titrated acid content, and inhibited the degradation of vitamin C. The application time of CaCl2 in pre- and post-harvest was not significantly different in term of physicochemical properties. Keywords: fruit softness, quality, weight loss, shelf life, vitamin C

The effect of storage temperature on the shelf life, weight loss, respiration rate and ethylene production of Hass avocado (Persea americana Mill) was studied. Two batches of green mature avocado fruits, classified as ‘‘super extra’’ were stored at 10 and 20 C (first batch) and at 7 and 25 C (second batch). The avocado shelf lives were 22, 8, 32 and 6 days at 10, 20, 7 and 25 C, respectively. Based on the data of the first assay Q10 was calculated as 2.75, with this value the predicted shelf life at 7 and 25 C were 29.8 and 4.8 days, respectively. That meant shelf life was underestimated 7 and 20% at 7 and 25 C, respectively. Weight loss was linear at both the storage temperatures, it was 4.3% in fruits at 20 C for 8 days and 3.0% at 10 C for 22 days. The maximum CO2 production at 20 C was reached during the second day of storage, while at 10 C it was reached at the 17th day (176.17 15.98 and 74.73 7.32 mL/kg h, respectively). The maximum ethylene production at 20 C was reached the second day of storage, and at 10 C the 6th day (239.06 54.55 and 28.00 8.12 mL/kg h, respectively).

In this experiment the effects of aloe vera gel coating on storage behavior of papaya at room temperature (290C-310C) was studied. Physico-chemical parameters such as color, physical changes, moisture, ash, acidity, vitamin C, protein, fat and total soluble solids (TSS) of papaya and aloe vera was determined at 3 days interval during the storage period. Among the physico-chemical parameters, color, physical changes, total weight loss and TSS contents increased significantly, whereas moisture content, vitamin C and titrable acidity decreased during storage. Control and 0.5% aloe vera treated papaya decayed from 6 days onward and completely decayed within 12 days of storage. On the other hand, 1% and 1.5% aloe vera gel coated papaya maintained their shelf-life for 9 and 12 days, respectively. Some of 1.5% aloe vera coated papaya decayed after 15 days. Papaya treated with 1.5% aloe vera solution, maintained their color & physical changes compared to other treatments up to 12 days of storage. The overall results showed the superiority of 1.5% aloe vera gel coating in extending the shelf-life of papaya upto 15 days compared to that of 0.5%, 1% aloe vera gel coating and control papaya. The present study describes the preparation and potential application of aloe vera gel coatings for enhancing the postharvest life and quality of papaya.J. Bangladesh Agril.

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.

The present study was run in the laboratory of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period of 15 May to September, 2016. The objectives of the study were to determine the effects of different postharvest treatments on the storage behaviour of litchi. Eight postharvest treatments viz., control, fruits stored in 50µ polypropylene bag at ambient temperature, fruits stored in 75µ polypropylene bag at ambient temperature, fruits stored in 100µ polypropylene bag at ambient temperature, fruits stored at 4ºC temperature, fruits stored in 50µ polypropylene bag at 4ºC temperature, fruits stored in 75µ polypropylene bag at 4ºC temperature, fruits stored in 100µ polypropylene bag at 4ºC temperature were assigned to the litchi fruits. The single factor experiment was laid out in a completely randomized design with three replications. 75µ polypropylene bag at low temperature (4ºC) caused minimal weight loss, whereas, the untreated fruits exhibited maximal weight loss. The pericarp turned brown within 4 days of storage in the untreated fruits, while polypropylene bags helped keep its bright red colour, but microbial decay was evident at the end of the storage period. Different postharvest treatments showed highly significant variation in the shelf life of litchi. Among the treated and untreated fruits, 75µ polypropylene bag at low temperature (4ºC) treatment exhibited better storage performance. The fruits kept in 75µ polypropylene bag at 4°C showed the highest shelf life (20.67 days) followed by 50µ polypropylene bag at 4°C (20.33 days), and it was the lowest in the untreated fruits (3 days).

Shallots (Allium ascalonicum L.) have a short shelf life because these tubers can experience decay and premature germination. Therefore, innovation is needed in shallot processing, one of which is by processing shallots into pasta products. This research conducted the making of onion paste with the addition of vegetable oil to improve the quality of the paste. The purpose of this study was to examine the effect of vegetable oil concentration treatment on shelf life and quality of shallot paste and to determine the level of preference for the panelists to shallot paste by organoleptic test. This study used a completely randomized design (CRD), namely one treatment factor with the addition of vegetable oil concentrations of 30%, 25%, and 20%. The data were analyzed using variance, if the results were significantly different, then it was further tested with DMRT with a significant level of 5%. The results showed that the concentration of vegetable oil on shelf life and quality of shallot paste were not significantly different so that the addition of vegetable oil concentration had no effect on shelf life and quality of shallot paste. Panelists preferred color and taste parameters of shallot paste with the addition of 30% vegetable oil. Meanwhile, for the pasta aroma that the panelists like, the paste with the addition of 25% and 20% vegetable oil.
