Introduction During the last decay the consumption of fresh leafy vegetables is increasing sharply as a habit to eat healthy and nutritious food. Short of cooling fruits and vegetables after harvest is the main reason that leads to postharvest losses. In developing countries the percentage of postharvest losses of fruits and vegetables may be increasing to hit up 80-100% in some situations. In contrast the process in developed countries is different, because the high demands for commodities. The best quality of these goods needs for transportation from farm to the storage and consumer during that these fruits and vegetables will lose weight that lead to reduce the quality. In order to reduce the weight loss for the commodity and maintains …show more content…
(Amira, 2013) Another study by (GHAOUTH, 1991) investigated daily to see the decay that fruits was infected. As well as, bell pepper, cucumber were evaluated for visual quality, color, wilting and shriveling. The degree of the evaluation from 6 t0 1, which is included outside appearance starts with color: 6, excellent (dark green); 4, good (green); 2 moderate; and 1 poor outside shape. The mean of individual fruits is the final grade. Material and methods Sampling An experiment was conducted to see the effect of cooling method AC, Quonset and Lab on extended shelf life for strawberries, blueberries, lettuce, and spinach. We put three plate samples in each location. Temperature and humidity for Ac, and Quonset were measured and recorded every 30 minutes by using temperature and humidity sensors. However the lab temperature and humidity were measured by the device. We compare it with the sensors we used in Ac room and the result is similar. Destructive quality evaluations firmness, color, odor, overall acceptability additional to weight loss were evaluated daily by two person in order to avoid bias. The aim of this experiment with goal of methods 1 or 2 extending shelf life by 7 days compared to methods 3 or 4. Each cooling method has a variety of sensors that can be used to quantify the storage conditions. Storage conditions 1 & 2 cannot be simultaneous. Temperature and humidity sensors used to quantify the storage conditions. Four replications or 4 containers of
In this lab we looked at the mold on three different fruits in three different environments to asses which fruit would have the most mold and in which environment the mold would be present the most. For the experiment we used fruits that were in season so that we could also compare organic and non-organic fruit. Because of this my group chose tomatoes, peaches and apples. We hypothesized that peaches would rot the most out of each of the fruits and that the peaches would rot the most in our warmest environment, the incubator. The fruits were then observed over a period of weeks. At the end of this period of time the peaches had rotted the most and burst and the peaches in the incubator were the first to go.
There are disadvantages and many of those disadvantages can be alleviated by using a form of food preservation that can extend the use of our food harvests even longer
During my high school years, I recall working in the fields during vacation breaks with my mother harvesting tomatoes, picking up cherries, and pruning grape vines. Fascinating as it sounds, I was always intrigued to understand why fruits and vegetables spoil or often cause food poising in humans. Although, when I questioned my mother why these fruits spoil, she responded it was due to “little bugs,” which was not a sufficient response.
Farmers have to consider the food quality checks. Farmers are aware of that if fruits or vegetables are not in a perfect shape supermarkets are not going to buy them, so farmers just throw away imperfect fruits and vegetables. Royte who is a nature writer, in her article “Eat Ugly!” she explained, “A lot of food sellers think no one will buy freaky-looking food. So they toss it before trying to sell it. Each year, 1.3 billion metric tons of food gets wasted in this way” (Royte). According to Richard Schiffman gave a solution for this problem in his article “What a Waste!” by giving the example of “Andronico's Community Markets in California” who sell imperfect looking fruits and vegetables to a very low price (Schiffman). This will help Famers and they don’t need to throw away the ugly looking products. The other reason food being wasted in fields by farmers is that they have to make sure that they have a steady supply of products for supermarkets (Matt and Peek). They purposed a solution for this problem, “With better food labeling—for example, using a spoils-on date rather than a sell-by date markets could keep their stock longer and ease demand on farmers” (Matt and Peek). The government should bring stricter policies to decrease food waste in fields and supermarkets can play an important role to reduce food waste
During distribution fruits and vegetables face a lot of safety issues from harvest, to washing, and to shipping. Not all
For the third tube, 6.109g of sugar was used, for the fourth tube, 8.02g of sugar was used and for the fifth and final tube, 10.013g of sugar was used. In the salt solution, test tube six, .6839 g of NaCl was used. For this discussion tube three, 6.109g of sugar, will be used to show how the freezing point was calculated for each solution. The first thing that was calculated was the molality.
The temperature of the product was monitored. At station 3, the temperature of the water (H2O) was measured. One fourth of a gram of sodium polyacrylate (C3H3NaO2) was placed in the test tube. Ten milliliters of H2O were added to the test tube. The temperature of the product was monitored.
The season for fresh fruit is quickly approaching as weather conditions continue to improve. Fresh fruit is a beautiful and exciting way to incorporate important nutrients into the daily diet. Unfortunately, fruit does not stay fresh forever, so it useful to know how to properly preserve fruits to keep them safe and nutritious.
Blueberries, lettuce, strawberries, and spinach were stored in three difference place, which were (Cool room, Quonset, and Lab), and the other experiment was to extended shelf life by using Hybrid cooling compare it with Quonset, and Lab for storing lettuce, cucumber, green pepper and tomato. The maximum of storage duration were 26, 16, 14, and 12 days at the cool room, for other storage method which was a lab the maximum of storage duration were 9, 8, 7, and 6, and for the ambient condition at Quonset were 8,7,6,and 5 days for blueberries, lettuce, strawberries, and spinach respectively.
In this investigation the extraneous variables that aroused included: the outside breeze from the corridor would have influenced the results because the set up was directly near the door, the temperature of the room was warm and humid therefore this affected the rate and way in which the food sample were burnt at. In order to improve this weakness the extraneous variables should be controlled by setting up the experiment in an area where the breeze is reduced to a minimum and the experiment should be set up in an area where the temperature of the room is at an
This is important when it comes to fresh fruits and vegetables which start to lose nutritional value the same moment they are harvested.
As shown in Table 1, the distillation column was determined to be in equilibrium after thirty-five minutes. However, there were errors in the measurements taken at the twenty and twenty-five minute mark. In both
In October of 2015, Muscular Development utilized authors Harris and Blechman article, Fat Loss Metabolism: The Dieter’s Dilemma. In this article, the authors discussed the dilemma of losing fat through boosting the metabolism with a diet. Harris and Blechman explained that there are two types of people when it comes to calorie intake, fat mass and energy expenditure, there are “savers” who are cautious of the number of calories they intake but continue to gain weight and then there the “spenders” who stay lean no matter how much they eat (Blechman and Harris, 2015). The article goes on to explain that these “savers” and “spenders” are predetermined during fetal development which resulted in the infants who were poorly nurtured to be born
Conventional shipping cartons have ventilation holes which allows air to circulate around the product, but this also allows the produce to continue ripening and exposes to bacteria and pathogens, which contributes to loss. FreshTec’s patented packaging technology employs a breathable plastic liner inside a cardboard carton, which is sealed with a plastic lid. It’s part of a growing segment of food packaging using modified atmosphere technology. The liner and plastic lid slow the amount of oxygen entering the carton and also traps some of the carbon dioxide the produce expels, effectively putting it to sleep for up to a month of travel time. Overall, FreshTec provides more time for produce to reach the market, which reduce the likelihood of loss or waste.
One topic that has been talked about for many years within Kinesiology is the debate on whether exercise or diet is more important for losing weight and maintaining weight loss. While both or important for a person's individual health, a person's diet is essentially the foundation for a healthy lifestyle and an important factor in losing weight and gaining nutrients that can help the body develop. Many studies and experiments have shown that a healthy diet goes a long way in helping people lose more weight, but more importantly teaches them how to continue to treat their bodies in a healthy manner. Dieting has been shown to have a bigger impact on weight loss than exercise has. For this reason, it can be said that a good diet is more effective for weight loss as compared to exercise alone.
