“The Potential of Market Vegetable Leftovers as Bio-Ethanol” by: Dexter B. Garachico STE (8) A- Mahogany “Related Literature” Market vegetable leftovers, are simply wastes to our environment but many of these waste can be essential in making a very useful product. These market vegetable leftovers are near to rot so they are useless to our environment. Vegetables contain a great variety of other phytochemicals, some of which have been claimed to have antioxidant, antibacterial, antifungal, antiviral and anticarcinogenic properties. Also, they are very fast to ferment. They also contain sugars and rich in vitamins. Market vegetable leftovers are easy to found and renewable and capable for the production of bio ethanol (Thomas 2014). Market vegetable left overs is the main subject of …show more content…
According to Junchen (2012), “Utilization of edible plants and crops are capable in the production of bio ethanol” market vegetable left over’s composed of different vegetables that can help me to make a more effective bioethanol. Many researchers like Hossain and David Pimentel are finding out more capable products to make a bioethanol. It includes natural resources, especially starch, vegetables, fruits and a product rich in sugar. For example in 2014 Alemayehu Gashaw tried to make a bioethanol from fruit waste and also concluded that when he increase the temperature he also get a greater amount of bioethanol. According to him “Lignocellulosic biomass has been used as one of the main resources for economically attractive bioethanol production. Though ethanol yields from sugar and starch and these are higher than from lignocelluloses these conventional sources are insufficient for worldwide bio ethanol production”. However in 2011 Hossain, Alshammari, Mustafa and

Cellulosic ethanol will not be able to meet its mandated output because in the past four years since demonstration and pilot sites started popping up it has only just started t...
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...
In the past decades the incidence of heart disease has increased, about three million people dying of cardiovascular disease in China per year (according to statistics from the Ministry of Public Health of China), which draws people’s great concern to find ways to take precautions. With the development of element analytical method, some types of chemical substances that are beneficial to cardiac health have been found. Lycopene is a very popular natural anti-oxidants found in recent years (Dai, 2011), as well as capsaicin and dietary fiber. Whilst some research focuses on the mechanism of action, little attention has been paid to usability issues, in particular to the generalization of health-giving chemical substances in ordinary meals. There is a lot of evidence that vegetables can positively contribute to prevent heart diseases, by supplying biologically active components. This article continues previous research in the field of Biochemistry and Medical Science, mainly trying to study the effective components which can prevent heart disease in edible vegetables.
Despite of general properties of enzymes, the properties also varies from where it comes from and how it been produced. For instance, the enzymatic saccharification method in lignocellulosic bioethanol is generated by hydrolyzing cellulose and hemicelluloses. This method gets high attention because of its higher theoretical yield compared to other methods (Taneda et al., 2012). Acremonium cellulolyticus with high activities of cellulase, amylase and pectinase enzymes allow it for the easy separation of solids/liquids in potato pulp, resulting in high saccharification efficiency and a high recovery rate of products (Gao et al., 2014). On the other hand, Enzyme-modified carboxymethyl starch (ECMS) is beneficial in enhancing water holding capacity, emulsion stability and improving sensory characteristics of sausages with a declined fat content (Luo and Xu, 2011). Lipases and phospholipases of dormant cotton seeds have stability in heat, various media and nature of the hydrolysis of the lipids properties (Rakhi...
Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...
Obtaining a secure supply of food is one of the most important parts of life. Acquiring food and its preparation is changing with the times, but the age-old art of preparing a healthy diet from natural ingredients is being put to use even today. After harvesting wild vegetables, those which are not eaten right away are dried and stored. It is important to provide an ample supply of food, because the summers are short and the winters are long in Hokkaido. The Ainu have made it a rule not to pick more than necessary, and of what was collected all o...
With the world’s population continuing to increase, the demand for food is higher than ever. This increase in food demand also calls for more efficient ways of growing and providing the food. Two methods that are very controversial are the organic and conventional method. While many people support the organic method because of its known benefits, others feel that it is an over inflated industry that cheats consumers out of their money. But recently many studies have disproved those critics. These studies prove that Organic food is a better choice than conventional because it is better for the environment, avoids the use of chemicals, and is generally more beneficial.
Biobutanol has the potential to replace ethanol as a fuel in the future. Recent studies suggested that it does not damage car engines like ethanol does, it reduces fuel mileage , and it can blended with gasoline directly in the refinery. In conclusion, butanol can make up for ethanol’s weaknesses. However, butanol fuel is said to be too expensive and not competitive enough to compete with ethanol.
When we say ethanol production we are referring to the use of ethanol as a hybrid fuel for automobiles. What hybrid fuels means is that instead of running a car solely off of ethanol or gasoline alone, ethanol is actually blended in with standard fuel grade gasoline to create the ethanol fuel hybrid. Ethanol is derived from alcohol; it is a grain alcohol that is typically broken down from corn, although it can be obtained by other means such as Brazilian sugar cane, wheat, barley and potatoes (West). The way ethanol is created, according to Larry West in an article titled How is Ethanol made, is by fermenting plant sugars from photosynthesis, treating them with enzymes followed by then inserting tiny microbes to feed on the sugar that will finally b...

Preparation of Ethanol and Ethanoic Acid Introduction to report ---------------------- This report contains 5 practical experiments to produce ethanoic acid from ethanol. The first practical is the preparation of ethanol from glucose using yeast during the process of fermentation; this has been demonstrated in class. In this practical the glucose is converted into ethanol and carbon dioxide by respiratory enzymes from the yeast. The ethanol solution will be between 5-15% and the ethanol will be separated from the yeast by filtering.
Fruits and vegetables are important components of our diet. We take fruits in raw state or in the form of juices, while vegetables are taken in the cooked form or sometimes as juices. Fruits and vegetables provide us carbohydrates, proteins and various other important organic compounds. The juices are rich sources of minerals, vitamins and many micronutrients (calcium, iron etc.) essential for us. For example, iron deficiency in humans causes anaemia and anaemic persons are advised to take leafy vegetables e.g. spinach and apples which fills up the iron deficiency.

Collected and dumped not eaten foods that means remains of a hot meal after the meal is over, and everyone has finished eating is called leftover food. West materials and food scraps also conceder as leftover food(Cho et al., 2004a). The ultimate fate of leftovers depends on where the meal was eaten, the preferences of the diner, and the prevailing social culture.
