Fruit Cultivation and Processing Improvement in Nigeria

Authors : I.B. Oluwalana

Abstract: This study reviews the problems of fruit wastage, seasonal glut, off season scarcity and how to ameli orate them in Nigeria. Tropical fruits which have high nutritional and medicinal values, are very seasonal and deteriorate speedily shortly after harvest. This situation needs to be arrested using suitable storage technologies.Known methods for extending the storage life of fruits particularly in the developed countries were reviewed to see how suitably they could be adopted to store tropical fruits inorder to reduce their wastages. These methods include hypobaric storage, controlled atmosphere storage, modified atmosphere storage, irradiation, chemical treatment and refrigeration. Most of the aforementioned methods have been found to be either too sophiscated/expensive or injurious to most tropical fruits. Storage technologies particularly, hypobaric, controlled atmosphere and irradiation are reported to be either too technical or capital intensive for fruit storage and marketing business in the developing tropical countries. Hence the technology not being compatible with the poor market values of the fruits. Refrigeration which could have been a better alternative to preserve tropical fruits also suffers a set back of erratic power supplies and even when power is available, it imposes a physiological disorder known as chilling injury to the fruits at temperatures below 15�C. The film packaging and chemical treatments are reported to have little or no significant preservative effects on the fruits if not combined with refrigeration. The combinations of chemical treatment, film packaging and refrigeration has been found to be very effective in minimizing the effect of chilling injury and extending storage life, but the cost still remains an issue. This study has revealed that, there is scarcity of technologically suitable and economically feasible methods of preserving fruits in their fresh form in the tropics resulting in their seasonal glut.(i.e The fruits are readily available at rock bottom prices during their seasons with high attendant wastages and become terribly scarce and expensive shortly after their seasons). Hence, the feasible approach to solving this problem therefore, is processing the fruits into more stable products such as juices, drinks, jellies and jams etc. The focus of this study is therefore to encourage processing of the fruits into juices. The main aim being to make their nutritional and medicinal benefits available to consumers, particularly in the tropics all year round.
