  • The Natural Development Of Banana Ripening Essay

    1350 Words  | 6 Pages

    Introduction Banana ripening is characterized as the process in which starch breaks down into sugar, acid is neutralized, aromatic compounds are formed from larger organic molecules, softening occurs due to a decrease in pectin concentration, and, finally, a change in color from the loss of chlorophyll and its green pigment. This natural development is due to a single organic gas: ethylene. As this hydrocarbon is produced by the fruit various enzymes are produced, catalyzing the previously stated

    encoding ACS and ACO have therefore been studied more deeply than other enzymes in the pathway, although there is proof that a few other genes concerned with methionine synthesis and methionine salvage pathway are differentially demonstrated throughout ripening and in response to ethylene (Alba and others 2005; Zegzouti and others 1999). ACS and ACO are encoded by multigene families in higher plants, with tomato having at most nine ACS (LEACS1A, LEACS1B, and LEACS2-8) and five ACO (LEACO1-5) genes (Barry

  • Questions On Cold Storage

    4. Discussion 4.1 Chilling injury index We previously reported that a 15-d period of cold storage at 5 °C was enough to develop CI symptoms in mature-green tomato fruit cv. Imperial (Vega-García et al., 2010). In agreement with those results, in the present study we observed CI symptoms after the fruit was stored 10 d at 5 °C, but they were more intense after 15 d of cold storage (Fig. 2). As expected, tomato fruit stored at 12 °C did not show CI symptoms (Malacrida et al., 2006; Bojórquez-Gálvez

  • Effects Of Pre Harvest Factors On The Final Quality Of A Product

    fertility, the nutritional composition of a fruit at harvest can vary widely. For example Banana and papayas increase in carotenoid content with maturation and ripeness, but the ascorbic acid content decrease in bananas and increase in papayas during ripening (Lee, 2000).Even within a cultivar, there is a large plant-to-plant variation and within-plant variation in nutrient composition of fruit harvested from the same field (Shewfelt, 1990). Water availability, sunlight, fertilization and chemical applications

    Back in the 19th century bananas were not widely known. In fact, the western world hardly consumed the fruit, because of its exotic origin. The cultivation of banana is not easy. Bananas are one of the most highly perishable products that also need specific weather conditions in order to thrive. Indeed, bananas are only cropped in tropical regions, where temperature never falls under 13-14 degrees Celsius with high percentage of humidity and well-drained soil. Moreover, countries with tropical climate

  • Proteolysis in Cheese Ripening

    1287 Words  | 5 Pages

    Proteolysis in Cheese Ripening: Proteolysis is one of the most complex biochemical events in cheese ripening that contributes to the typical taste, texture, and aroma of every cheese variety. This fundamental process in cheese ripening is caused by agents from several sources such as indigenous milk enzymes, lasting coagulant, and enzymes from secondary flora. As a result of its importance, proteolysis has been a key subject of active analysis in the past decade as new evaluation techniques are

  • The Impact of Lipolysis on Different Cheese Varieties

    1305 Words  | 5 Pages

    Different Cheese Varieties Introduction During the process of ripening, biochemical processes that take place in the cheese are the most importance factors that contribute in speedy ripening process. Other than well studied, proteolysis, most important roles in cheese ripening involves lipolysis, the fat burning process. Ripening is the main process in which development of the cheese flavor takes place. During the process of ripening a large number of sapid compounds are produced which if present

  • The Effect Of Maturity Indices, Post Harvest Treatments And Storage Temperature On Shelf Life Of Mango

    2175 Words  | 9 Pages

    Navsari 396450, E-mail: ABSTRACT Shelf-life of fruit was significantly enhanced with minimum ripening percentage, higher number of healthy fruit percentage in Kesar mango having sp. gr. < 1.00 (M3) fallowed by sp. gr. 1.00-1.02 (M2). Wax coating 6 per cent (R3) was effective to increasing the shelf-life of fruit, ripening days, healthy fruit per cent and minimum ripening per cent. Soft-rot diseases incidence was does not found in hot water (R1) and bavistin (R2) treatments. A comparative

    in milk. Today, more than fourteen hundred types of cheese exist, each with a distinct taste. (Thompson, 2007)The manufacturing of cheese is through several processes that are, pasteurization, adding additives, milk ripening and coagulation, curd treatment and finally cheese ripening. (Goff, 1995) PH monitoring, along with the casein to moisture ratio, is the most important step that determines cheese texture. Certain cheese varieties, such as Swiss, Gouda and Cheshire cheese exhibit a narrower
