Tomato fruit quality for the fresh market has been improved for over 30 years (Causse et al., 2001). Fruit quality was divided in to two parts, internal quality, and external quality (Mata, 2000). Mata (2000) also indicated that a wide range of tomato currently available in the market were of high yield and extraordinary external quality. Tomato fruit contribute to nutrition worldwide, and contain diverse antioxidant molecules (Sacco et al., 2013). Fruit quality of tomato is very important attribute for the cultivated tomato. That good quality may contribute to a reduction in the risk of certain type of cancer and cardiovascular diseases (Causse et al., 2003).
Tomato fruit qualities were always targeted in breeding, and included organoleptic

Tomatoes taste either sweet or acidic, but the question why? Varieties that taste most acidic, or sour, have a higher level of acids combined with a low level of sugars. Sweet tasting varieties the sugar levels were higher than acidic or sour. On the other hands varieties with low levels of sugar and acids had a bland taste. Texture traits of tomato fruits have been difficult to relate to physical measurements or fruit composition (Maharaj et al., 2007). In terms of marketable tomato fruit quality, texture is also a critical component desired by consumers (Chaib et al., 2007). Texture combines different traits such as flesh firmness, mealiness, meltiness, juiciness and crispness. Fruit color is also an important trait in consumer perception of fruit quality. Previously breeders targeted market requirements such as traits affecting shelf life, resistance to diseases, fruit size, and physical appearance. Recently, tomato breeders have included the preference of consumer (Klee et al., …show more content…
Tomato fruit containing Vitamin C (ascorbic acid) play a key role in delaying the pathogenesis of a variety of deteriorating diseases such as cardiovascular diseases (Adalid et al., 2010), cancers, and neurological disorders (Galiana et al., 2006). Nutritional value is related to high content of antioxidants (mainly from vitamin C and carotenoids). However, tomato breeders continue to try and improve nutrition quality. Soluble solid content of tomato fruit represents 60% of dry matter in ripe fruits (Galiana et al., 2006). The shelf-life of tomato fruit is critical for marketing, transportation and domestic use (Adhi et al., 2013). Fruit shelf-life depends on both genetic factors, and also environmental factors, such as temperature (Adhi et al., 2013). Traits proposed by breeders to improve shelf life before consumption include pericarp thickness, fruit firmness, and number of locules.
Yield increase of hybrid varieties was accompanied by an increase in fruit weight, fruit number. Fruit number played greater role that fruit weight in improving marketable yield of tomato hybrids (Garg et al.,
It not only tastes better, but are closer to a maximum of nutrition than store-bought produce (Source D)
Anthocyanins, flavanols, flavanones,secoiridoids, phenolic acids, stilbenes, coumarins, and isoflavones form a large class of polyphenols, which are phenolic compounds. This study, however, focuses on one category of these phenolic compounds: phenolic acids. These particular compounds have been classified into two groups, namely hydroxycinnamic acids and hydroxybenzoic acids. The most common hydroxybenzoic acids are protocatechuic acid and gallic acid, while hydroxycinnamic acids include ferulic acid, coumaric acid, caffeic acid, chlorogenic acid, and sinapic acid, (Nigdikar, Williams, Griffin, & Howard). Unlike hydroxycinnamic acids, hydroxybenzoic acids usually occur at very low levels in some black radish, red fruits, and onions, accounting for about 10 ppm on a fresh weight basis. Protocatechuic ac...
...to plant, Solanum lycopersicum, conferring disease resistance has also been shown to be beneficial to health, as the modification results increased nutrient content, antioxidant activity, and lycopene concentration [3]. By insertion of rolB gene from A. rhizogenes into tomatoes, there are beneficial effects. Though this is one case of success, it is definite that researchers can eventually research and produce successful products of biotechnology.
Vitamin C, also known as Ascorbic Acid, has the structural formula C6H8O6. Vitamin C is an essential nutrient believed to have very important benefits to the human body and it enables the body to make efficient use of carbohydrates, fats, and protein. It is needed by the body to repair bones, teeth, and cartilage; heal wounds and scars; help the body absorb iron from certain substances, and promote a healthy immune system. Vitamin C is also needed to form collagen, which is a protein used to make skin tissue, blood vessels, ligaments, and tendons. Vitamin C is an antioxidant, meaning it protects the body’s cells against oxidation and the destructive effects of free radicals within the body. It is also believed that vitamin C helps to prevent
Vitamin C is a necessary vitamin for the body to carry out its functions properly. It is also known as ascorbic acid. It is a water-soluble nutrient that is found in some foods. It acts as an antioxidant in the body which helps to protect cells from the damage caused by free radicals, which are formed when our bodies convert the food we eat into energy. The body needs vitamin C to make collagen which is the protein required in wounds, healing. Moreover, vitamin C promotes the absorption of iron from fruits and vegetables and helps in promoting the immune system. Vitamin C is also important to protect our body from cardiovascular disease, prenatal health problems, eye disease, and skin wrinkling. We can obtain vitamin C from food and other sources.
Vitamin C in the body acts as an antioxidant. Vitamin C loses electrons easily, a characteristic that allows it to perform as an antioxidant. In the body, antioxidants defend against free radicals. A free radical is a molecule with one or more unpaired electrons, which makes it unstable and highly reactive. By donating an electron or two, antioxidants neutralize free radicals and protect other substances from their damage. Figure 1 illustrates how vitamin C can give up electrons to stop free radical damage and then accept them again to become reactivated. This recycling of vitamin C is key to limiting losses and maintaining a reserve of
Heirloom vegetables may look the same as any other vegetables, but they are far from ordinary. The only difference is that they were not crossbred with other planted vegetables. When vegetables are referred to as heirloom it just means that they are from an old crop (“Hot Food Trend 2017”). Heirloom vegetables have many positive benefits. Many cooks prefer using heirloom vegetables because of their positive effects. Today’s society should be more open to the trend of heirloom vegetables because of their effects on health, their environmental effects, and their appealing attributes.
I newly found out that every “One ounce of chile contains as much as 20,000 units of Vitamin A, which is twice the minimum daily requirement” (19). Which is surprising for me because ever since I was a child, my thoughts about chiles is that it only gives spiciness to a food. I didn’t know that a chile has something more to give. I also discovered about the jalapeño that “One hundred grams of Texas green chile contains 235 mg. of vitamin C while a California orange has but 49 mg” (19). Its an astounding and shocking because of the revealing information that jalapeños gives more vitamins than the oranges. Now, I know that not only oranges are good supplier of vitamins, but jalapeños also are a good source of vitamin C and also vitamin A which essential part of our body. In addition to that, Burciaga mentioned that “Calcium content in chiles is also high”(19) which gives me an additional information that chiles are also rich in minerals that is very important for our bone
Chemical advancement in modern science is a contributing factor to “better”, faster, and cheaper food production. Although the ideas of GMO’s (Genetically Modified Organisms) that scientists thrive for are theoretically beneficial, they are corrupting the natural methods for farming and food that consumers will purchase. Nowadays, around 70% of food has a genetically modified ingredient. What is being consumed in mass quantities across the country barely constitutes as food in some instances. A prime example lies in the tomato. Tomatoes are sold year round in grocery markets nationwide....
In this experiment, we will explore the properties of fresh potato extract in Phosphate buffer pH6 containing the enzyme polyphenol-oxidase and measure the different concentration of this enzyme activity by observing the production of pink/gold melanin, when 0.1% catechol and phosphate buffer pH6 is mixed into the solution. At this stage of the experiment, we are assuming that all other variables that can act as inhibitors of the enzymatic activity such as temperature or pH levels are under control. Fruits and vegetables are known to have small amounts of catechol and polyphenol-oxidase (enzyme), which are the cause of the production of browning effect in the out-layer skin or liquid of the fruit or vegetable when it is damaged. Polyphenol-oxidase
Vitamin C also known as ascorbic acid is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, teeth. Vitamin C aids in resistance against infection and healing of wounds. It also helps the body absorb iron from food. Vitamin C can be found in green vegetables, potatoes, tomatoes and citrus fruits such as oranges and lemon. A lack of vitamin C can cause scurvy, iron deficiency and poor wound healing. A healthy diet should include a high amount of vitamin C because the human body cannot produce its own vitamin C.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.
There are only two negative aspects of vitamin C. It is not produced in the human body, so a person needs to have a daily intake of at least 60 mg (recommended daily value) to stay healthy (5). There are many ways for a person to obtain vitamin C. One way is to take a daily vitamin that contains 100% of the recommended amount. Other ways to receive the amount needed is to eat foods that are rich in vitamin C. Some fruit rich in vitamin C are oranges, grapefruit, watermelon, and strawberries. Some vegetables that contain a high amount of vitamin C are asparagus, brussel s...
The nutrients we get from eating fruits and vegetables are also very important in our daily diet. When we eat anything we get nutrients from it, but the question is are we eating too much? Too much of a good thing can be bad! The different vitamins have many different purposes, vitamin A keeps the eyes and skin healthy and helps protect against infections. Vitamin C helps heal cuts and wounds and keeps your teeth and gums healthy.
This clearly shows that the fruits and vegetables play a vital role in maintaining our good health. Fruits and vegetables are seasonal and grown in different parts of our country. They need to be stored for longer period and transported to different places. It makes necessary for us to find out whether there is any damage to the useful contents of the fruits and vegetable during the storage and transportation or due to some preservatives or other factors and what kind of nutrients, minerals, etc. are present in their juices. With this idea in mind, the project has been undertaken.
