Effects of Pre-harvest Factors
Pre-harvest factors can influence the final quality of a product including papaya. Post-harvest product qualities develop during growing of the product and are maintained and not improved by post-harvest technologies (Hewett, 2006). Depending on the cultivar, maturity, climate, soil type and 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 are some of the pre-harvest factors which not only affect crop growth but also internal quality characteristics of the harvested product, including flavor. Pre-harvest treatment with aminoethoxyvinylglycine (AVG) suppressed volatile production in pears by 50% and heavy rains prior to harvest dilute flavor compounds in tomato (Romani R, 1983).
Effects of Harvest Maturity
Maturity is among the critical factors influencing the abundance of volatile compounds in papaya fruit. To optimize volatile content for flavor, papaya fruits should be harvested at an optimal eating quality as opposed to immature papaya fruits which are often harvested in order to
Christopher Columbus account on the meeting of the Arawak for the first time consists of many tragic events in history. However, there are two different points of view that should be considered upon the opinion of Christopher himself, and Bartolome de Las Casas. Comparing and contrasting the two documents one can truly see that the truth would always come to light. In Christopher Columbus voyage, he had mentioned that the Native Americans were nothing more than loving as they were willing to give as much as they could without any resentment. As they were always lavish with everything in their possession. In the second passage, Bartolome de Las Casas has also indicated that the Indians were rational and wise individuals. They never had any desire or feeling of hate toward another
The entry discussed ways in which to improve percentage yield when synthesizing flavor acetates, Isoamyl acetate (Isopentyl acetate) was used to test these changes. The article had a percentile yield of 80% an 22.31 difference in percentage yield that what was obtained in the lab period, adjusting to these changing could help improving the results. The broader impact is that Isopentyl acetate is a natural occurrence in banana plants and is produced synthetically to mimic banana flavor in foods.
The article was written by Sharon Fraser BA, MS a clinical speech pathologist and a graduate student of Faculty of Religion, Loma Linda University, California and James W Walters, PhD from Bluefield State College, professor of Ethics in the Faculty of Religion, Loma Linda University, California. It was published online by Journal of Medical Ethics April 2000. The article addresses the general population that argues against legalizing euthanasia for terminally ill people backed up the real facts and various statistics. The article is well researched and evaluated backed up by various relevant resources that
The author of the book, “The Fate of the Fruit that Changed the World” (2008), Dan Koeppel, who is a famous journalist describes in a fascinating way banana’s cultural importance, threats associated with the crops of banana in the future and banana’ history. Banana is a very delicious fruit and is eaten all over the world. Banana is one of the world’s fourth largest harvests in the world. Dole and Chiquita are eminent American based distributors and producers of banana. They are claiming to produce the banana on low price. In this book, Koeppel discusses the risks associated to the plantation of banana around the world. He also discusses the fact that due to blight, the plantation of banana is destroyed (Koeppel, 2008). He points out that the farmers and the producers have no insight at all regarding this matter (Koeppel, 2008).
Plants release ethylene, an hormone that triggers ripening in mature fruit. It is responsible for ripening all the delicious fruits we love such as apples, bananas, avocados, and tomatoes. Ethylene is a chemical that is used in industry to allow farmers to ship their produce all over the country and get reach the consumers still fresh. The trick is to harvest the fruit when they are unripe and to spray them with ethylene. Similarly, if the farmers do not want their fruits to be ready for consumption, they use another solution to block the effect of ethylene.
Conversely, The Flavr Savour tomato possesses supressed activity of the enzyme polygalacturonase. The suppression contributes to the fruits ability to stay harder for longer allowing it to stay on the vine. This suppression allows the tomato to develop its natural flavours and ripen as it stays on the vine for a longer time period. This flavour saving process lead to the products name “The Flavr Savr”.
Characterizing the volatile components of N. sativa seeds essential oil is necessary to understand its role in food flavor and its potential applications in the fields of medicine. The approximate yield of the volatile flavor concentrates obtained from 25 g of N. sativa seeds was 0.28 g (1.1%) and 0.06 g (0.24%) from Bangladesh and Indian seeds, respectively.
For canned peaches, the most important raw material would be the harvest of peaches. The food processing company has to purchase harvest of peaches from its suppliers, which would be mainly farms. Uncertainty may come from physical factors that affect the supply of the peaches, such as weather conditions, or natural disasters. These factors would inevitably affect the availability of peaches.
Pepper Lovers, must therefore be able to adapt to macro environmental changes, and a PESTEL analysis would help the company strategically plan for all possible macro environmental events that may affect the Trinidadian pepper sauce producing
The results indicated that sowing broad bean plants at wide spacing (30 cm) achieved the significant highest mean value of earliness, in both experiments and nods setting percentage, in the first experiment only. The enhancing effects of wide spacing (low plant density) on earliness and fruits setting could be related to the best utilization of mineral uptake in metabolism and meristimic activity, causing better vegetative growth, which is able to produce photosynthetic products accumulation required for earliness and pods formation. These results agreed with Abdalla (2006) and Yucel (2013) and Abubaker (2008).
Global food demand is expected to grow by 110 per cent over the next 30 to 35 years as a consequence of increased urbanization and the predicted rise in global population from 7.3 billion today to 9.7 billion by 20501. Overlying this scenario are changes in the global climate that will affect crop productivity. Cassava is the second most important source of calories after maize in some African countries, like Angola and Mozambique, but for the rural poor, it represents a much larger proportion of daily calories and provides an important source of proteins, vitamins and micronutrients1. The vision for cassava is that cassava will spur rural industrial development and raise incomes for producers, processors and traders and contribute to the food security status of its producing and consuming households6.
The duration of time between harvesting and cooling is also of great significance when it comes to the disease development. The recommended fruit elapsed time should be no longer than 48 hours from harvesting to storing in refrigerator (Finlay and Brown 1993).
Papaya kills the intestine worms and other infections and thus prevents the further action of it. This is also one of the reasons why digestion goes smoothly in our body.
“Effect of Cultural and Chemical Treatments on Fruit Set, Yield and Quality of Custard Apple”,
The vegetables and fruits like capsicum, cucumber and even carrot selection is best one because it is widely used on regular basis. The sample preparation comes in to being when it is being cooled until 4 degree centigrade. The sample is being selected with all kinds of risk assessment from internal climate change to external one. There is proper need of sampling and scattering issues and those issues are being established with efforts of researcher.
