These changes begin in an inner part of the fruit, the locule, which is the gel-like tissue surrounding the seeds. The fruit goes through the growth stages of cell division, cell expansion, fruit maturity, and fruit ripening, then ends in fruit senescence. Journal of the American Society for Horticultural Science, v.125, p.357-363, 2000. Washington, DC: AOAC, 1984. The Chemical reactions of the fruit ripping change the shape, color, taste, texture, and smell of the fruit. During the preclimacteric period, fruits are less susceptible to physical damage and pathological attack. Analysis of variance revealed (P < 0.01) differences in these parameters based on ripeness stages. Texture • Fruits soften during ripening • Softening is due to the breakdown of starch and other non-pectic polysaccharides in the pulp • This reduce cellular rigidity • Change in the moisture status contributes to the ease with the detaching of the peel from the pulp • There are changes in pectic polymers during ripening 9. armers have to match the date of harvest with the transportation time to the market. Fruit color was evaluated by measuring Hunter L (brightness, 100 = white, 0 = black), a (+, red; -, green) and b (+, yellow; -, blue) parameters by means of a reflectance colorimeter (CR 300, Chromometer, Minolta, Japan). The physical indication that ripening is taking place in a fruit is that the colour of the external covering starts to change from green to red, purple, blue and various shades of these colours.
