Abstract/ Executive Summary:

The experiment was conducted to evaluate the effect of temperature and packaging on the quality and shelf life of yard long bean during transportation and storage. Yard long bean pre-treated with chlorine (200 ppm chlorox/halotab, 2 tablets per 1.5 litre water) water and then transported in corrugated fiber board (CFB) cartoon maintaining the temperature at 18-22^oC and storing in 6°C temperature maintaining 90% RH showed better quality and shelf life up to 15 days of storage. Storage of the yard long bean with proper cool chain management resulted substantial reduction in losses due to physiological weight loss and rotting/shriveling and retained considerable marketable quality as compared to control treatment

Objectives:

Objective of the study was to evaluate the effect of temperature and packaging on the quality and shelf life of yard long bean during transportation and storage.

Methodology:

Fresh yard long bean (Vigna sesquipedalis) was collected from the producers' field. The beans were sorted out to remove the anthracnose affected, over matured and damaged ones in the farmers' field. Then, the beans were washed with chlorine (200 ppm chloroxlhalotab, 2 tablets per 1.5 litre water) water. After removal of water naturally these were packed in corrugated fiber board (CFB) cartoon and transported in refrigerated van to the laboratory of Postharvest Technology Division maintain the temperature at 18-22°C. After arrival at the laboratory the CFB cartons containing the beans were transferred to the constant temperature and humidity chambers for storage. The treatments of the experiment were laid out in CRD with five replications as follows: T₁ = Stored at 6°C and 90% relative humidity, T₂= Stored at 8°C and 90% relative humidity, T₃= Stored at 10°C and 90% relative humidity, T₄= Stored at 12°C and 90% relative humidity, T₅= Control, Each replication of the treatments consisted of fifteen kilograms yard long bean. After storage in the constant temperature and humidity chambers close observations were made to record the physico- chemical parameters, shelf life, weight loss, marketability and rotting of the beans.

Achievement/Findings:

Yard long bean treated with 200 ppm chlorine water (chlorax), packed in CFB carton, transported in refrigerated van at 18-22⁰C, and kept in 6°C temperature maintaining 90% RH showed better quality and shelf life up to 15 days of storage.
