A review on post-harvest technology of an underutilized vegetable bitter tomato (Solanum aethiopicum L cv. gilo) of Northeastern region of India

Abstract

Northeastern region of India is endowed with variety of local vegetables that are highly nutritious and health-promoting. One of which is Solanum aethiopicum L which has a bountiful source of nutrients and bioactive chemicals. It has several pharmacological benefits and are used in indigenous medicine to treat various conditions. Nonetheless, the crop is highly perishable with a short shelf life (35days) which significantly contributes to postharvest losses. Techniques used to extend the shelf life of the crop are freezing, drying and refrigeration. The crop can be stored at low temperatures about 10-12oC. Fruits kept in perforated polyethylene bags had the longest shelf life. Important materials include polyethylene, polypropylene, and polystyrene are commonly used and coating can be applied to increase the crop’s shelf life. The crop has a huge potential in making value added products like pickles, dehydrated products and many more. However, concerns related to postharvest and production of the crop have not received equal attention due to scant research with the crop being neglected and underutilized due to lack of awareness and limited market. Considering the crop offers many advantages, popularization of the crop is essential but adapting to the bitter taste and flavor of the fruit could be challenging for the consumers. Consumer attitudes, views, and willingness to pay for products that have undergone particular post-harvest procedures require further investigation. Proper cultivation techniques, processing, value addition and marketing are required to surpass these hurdles.
