It is guided by the following sub headings; Intrinsic factors in fruit which includes; • The Ph • water activity • Available nutrients • Oxidation-reduction • Physical structure of food Intrinsic factors in fruit juices Prevention of microbial spoilage Conclusion Fresh fruits and fruit juices are nutritious and add value to our diet. They have an average composition of 85% water, 13% carbohydrates, 0.9% protein, 0.5% fat, 0.5% ash, trace amounts of vitamins and nucleotides, less water and more carbohydrates. Their pH ranges from 1.8-5.6. Consumption of fruits has increased drastically by more than 30% for the reason that people now are aware of health eating habits (Kaufman, Handy, McLaughlin, Park & Green, 2001). On the contrary, inappropriate manipulation and storage conditions have made fruits become a source of disease
Grocery stores offer a wide selection of fruits and vegetables that are available year-round. By the time these fruits and vegetables reach someone's home, the harvest process was done days and even weeks ago. Most of the fruits and vegetables are not in season and come from other parts of the world. These fruits and vegetables contain chemicals to help with their preservation.

Fruits such as grapes, oranges, and pineapples have a pulp texture which causes extreme pain for me during digestion. Fruits such as bananas and peaches are less painful, so I plan to identify more fruits like these to incorporate in my diet. I have had pleasant experiences with fruit yogurt cups and V8 Fusion in the past, so I plan to use these to meet my appropriate fruit intake.

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.
According to the World Health Organisation, low fruit and vegetable consumption is among the top ten risk factors contributing to global mortality. In 2003, low fruit and vegetable consumption was estimated to be responsible for 2.1% of the total burden of disease in Australia (World Health Organisation, 2011).
Beyond the microbrewery, a growing number of households are using fermentation techniques that preserve fruits and vegetables all year long, without the use of electricity. Long before the advent of refrigeration, ancient food preservation techniques, one being fermentation, were utilized to make fruits and vegetables safe for consumption available long after the growing season had ended. It is still used by many cultures today to produce crunchy pickles, tangy fruit chutneys and zesty sauerkraut. Essentially, it is a metabolic process that converts the starches and sugars found naturally in vegetables and fruits into food preserving alcohols and gases, which hinders the growth of harmful bacteria while encouraging the reproduction of beneficial

Fruits and vegetables have a very essential role in our diet. Studies have shown the importance of sufficient fruit and vegetable consumption in stopping chronic diseases like cardiovascular diseases, cancers, diabetes and obesity. According to 2000 report, “2.7 million deaths and 1.8% all diseases worldwide could be attributed to inadequate F&V intake” (Najimi, 2013). Starting to eat well when young is important. Research has proven that interventions at a young age can impact good behavior such as good nutritional habits that get carried on into adulthood. Furthermore, ages 7 to 12 is when a child should get nutrients for growing. Therefore, the significance of a child’s nutrition becomes more of a need than ever (Najimi, 2013). Examples of the benefits of kids eating healthy when young are good mental activities, prevention of problems and complications like anaemia, obesity, digestive disorders, and tooth decay and chronic and dangerous diseases in the long term (Najimi, 2013).

It is that first bite you take of one of your juicy and savory store bought apples that just sends your taste buds wild. You can tell by how juicy it is that the apple was probably picked fresh last week. However, that is not the case. That apple had been picked mid-august while it was not fully ripe, was treated with a chemical called 1-MCP (Methylcyclopropene), waxed, boxed, and stored in a cold warehouse for up to 9-12 months. Apples used to be sprayed with fungicide before they used 1-MCP, but after so many health issues it was put to a stop. We have no idea of what is really being put into our food to give them the tastes that we enjoy so much. Unfortunately, American society today barely even knows how food is grown anymore.

Fruits and vegetables provide (FODMAPs) fermentable substrate for predominating pathogenic microbes,2 while necrotized intestinal tissues provide additional substrate for pathogens;
Some benefits can also benefit the product itself. Like many other lactic acid bacteria lactobacillus plantarum229v releases lactic acid if in dairy based product lactic acid might bring a negative side effect of giving it a crude rancid taste and smell in juices with a sour taste like orange, black current, and mango these lactic acid give or enhance the taste. According to a 2006 study of comparison of both probiotic and non-probiotic juice, juices containing lactobacillus plantarum yields a higher mark with emphasis on them being more fragrant and tasteful. Another side effect of these lactic acid is that the lactobacillus plantarum uses the lactic acid to control competing microorganism this affects the product by giving it a longer shelf life without any excessive amount of sugar and or any other added preservative.it is also worth mentioning that by eliminating the need of any preservative production cost can be cut down significantly and the product can now avoid any problems based on the use of
