AN INVESTIGATION ON SPOILT PERSEA AMERICANA
The Avocado fruit, Persea americana is a tropical and sub-tropical fruit tree, originated in central America or adjoining regions of North or South America. It has now spread too much of the near tropical world. The avocado is limited especially by its climatic requirements, with race differences. It is also highly susceptible to drought injury. But excess soil moisture is equally fatal, encouraging the dread phytophthora root in most of the world, and where the fungus is unknown. Despite the high water activity of most fruits, the low PH leads to their spoilage being dominated by fungi, both yeast and molds. Other common diseases of pears include the black spot or scab caused by as comycetes. (Bezundenhouit J.J. 1992)
Avocado fruits has being estimated that one fourth of all produce harvested is not consumed before spoilage (Salulche, 1974), spoilage of fresh fruits usually occurs during storage and transport and while waiting to be processed unlike many other foods fruits after picking and before processing, microbiological spoilage problems are really market diseases of these products
Shape, varies from slightly obligate to highly elongate, an intermediate oval or pear shape is preferred, yellow to purple or black. (Sheperd J.S: 1990)
The composition of the fruit influences as the likely type of spoilage. Thus bacteria soft rot is widespread for the most part among the fruits is limited to those that are not highly acid. Because most fruits are some how acid and are fairy dry at the surface, and are deficient in B vitamins, moulds are the most common causes of spoilage. The compositions too, must determine the particular kind of moulds most likely to grow, thus avocado support a large, variety of fungal spoilage organisms and other kinds comparatively few. (Prusky and N.T. Keen 1993).
1.2 STATEMENT OF PROBLEM
Micro-organisms are known to destroy fruits, thereby reducing the quantity for consumption and the profits desirable from fruits such as avocado. Many spot are noticed on pears which do change the taste when consumed.
Bacteria and fungi are harmful and useful living organisms. The spoilage of most fruits is always associated with bacteria and fungi, many diseases of plants are associated with bacteria and fungi (Micro-organisms).
