Storage Temperatures

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).

Postharvest Treatments

An experiment was conducted to evaluate the changes in the chemical properties of banana fruits and their shelf life as influenced by different postharvest treatments. There were two varieties viz. Amritasagar (VI) and Sabri (V2) and seven storage treatments viz.: control (open space, 30±2ºC) (T0); perforated polyethylene, 30±2ºC (T1); non-perforated polyethylene, 30±2ºC (T2); benzyl adenine (BA 30 ppm, 30±2ºC) (T3); gibberellic acid (GA3 150 ppm, 30±2ºC) (T4); benzyl adenine (BA 30 ppm, 15°C ) (T5) and gibberellic acid (GA3 150 ppm, 15°C) (T6). A factorial experiment was laid out in the Completely Randomized Design (CRD) with three replications. Data were recorded on titratable acid content, total sugar content, reducing sugar content, non-reducing sugar content, total soluble solids and pulp pH. Among the chemical parameters, total soluble solids (TSS) and pH of pulp increased while titratable acidity decreased during storage in all the treated and untreated banana fruits. Among the treatments gibberellic acid (GA3 150 ppm, 15°C) treatment exhibited the best storage performance. The treatment combinations of Sabri with gibberellic acid (GA3 150 ppm, 15°C) showed the longest shelf life (16.25 days), whereas the lowest shelf life was in Amritasagar with control (open space, 30±2ºC) treatment combination (6.78 days).The Agriculturists 2014; 12(2) 06-17

Effect Of Chlorine

An experiment was conducted to study the effect of chlorine, packaging and storage conditions on quality and shelf life of tomato. Tomato treated with chlorine; packed in perforated (0.25%) polyethylene bag and kept at ambient (Temperature 20-25°C & relative humidity 70-90%) condition resulted in substantial reduction in losses caused by decay and weight loss. This treatment combination also considerably delayed compositional changes in TSS, total sugar, reducing sugar, vitamin-C, B-carotene, etc. Under this condition, shelf life of tomato had extended upto 17 days as compared to non-treated and kept in ambient condition without packaging or packed in gunny bag for 7 days only.

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).
