This chapter deals with the results of the experiments which were discussed in above chapter. The applications of ginger oil as edible coating on tomatoes were evaluated.
4.1 PHYSICAL AND CHEMICAL EVALUATION OF GINGER POWDER The ginger powder was subjected to proximate analysis and the results obtained showed that the ginger contained 4.0% ash content, 10.5%moisture content. The variations in the proximate parameters may be due to the difference in variety of the plant and geographical area of cultivation.

The study of these quality parameters shows that in controlled tomato, degradation started on 4th day of storage, in 1% concentration edible coated tomatoes degradation started on 8th day of storage, in 1.5% concentration edible coated tomatoes degradation started on 12th day of storage and in 2% concentration edible coated tomatoes degradation started on 16th day of storage. The study showed that there is a regular decrease in the weight of tomatoes. The controlled tomatoes losses weight on a faster pace than the ginger oil coated tomatoes. Although 2% conc. coated tomatoes loses weight but slower than other coated tomatoes. Firmness also decreased like weight in all coated and controlled tomatoes but the rate was very slow in 2% coated tomatoes than others. TSS increased in all coated and controlled tomatoes. In controlled tomatoes the increase rate of TSS is highest and in 2% coated tomatoes the rate is
Purpose: To identify the mystery powder based on its physical and chemical properties, comparing them to the five substances and which one matches. The chemical reactions with water, universal indicator, vinegar and Iodine solution are then analyzed and matched with each other to determine the mystery powder.
Directed by John Fawcett, Ginger Snaps (2000) tells the story of two teenage sisters after one of them, Ginger, is bitten by a werewolf. The night Ginger is bitten happens to be the night she starts her first period. Ginger Snaps uses the confusing and often scary process of becoming a werewolf as a metaphor for female adolescence.
The cigarette beetle is one of the most common household insect that causes damage to stored products such as dried materials of animal and vegetable origin, nuts, herbs, spices, grains and grain products etc. They usually feed heavily at the larval stage (Cabrera, 2007). The insects are also found to develop favourably on root and tuber crops such as cassava, yam, cocoyam and sweet potato mostly in the dried or processed state for storage (Adebayor, 2002). The insect usually infest and contaminates stored products with their cocoons and body parts when they die, thereby reducing the qualitative and quantitative value of the stored product which makes it undesirable for human consumption (Buss and Fasulo, 2006). The rate of development of the cigarette beetle is dependent on the food source and environmental factors such as temperature and relative humidity (Rees, 2004). The longest developmental stage is usually recorded at the larval stage where most feeding is done; the longevity of the adult insect is usually dependent on the type and quantity of food consumed during the larval stage (Papadopoulou, 2006; Mahroof and Phillips, 2008).
Advertisements stand as a method of persuasion in order to sell a product. Starbucks, a high-quality coffee café was originally founded in 1971 in Seattle, Washington as a coffee bean and ground retailer fine restaurants. The name, inspired by a character in the book Moby Dick, captures the romance of the high seas and the seafaring tradition and history of early coffee traders. By 1986, Starbucks had become a popular coffeehouse chain inspired by the romance of espresso bars in Milan, Italy. Starbucks claims their goal is to create a connection with the consumer. Starbuck’s advertisements engage and spark your emotions visually which in-turn evokes desires. In this advertisement from Starbucks, we see the coffee chain is promoting their seasonal Pumpkin Spice Latte.
Cultures are becoming obsessed with pumpkin spice flavors because it’s just a good flavor. Other reasons why people are obsessed because it’s a newer thing. I really don’t know why everybody likes it I guess just because it’s good. I mean how could you pass up a pumpkin spice latte or pumpkin spice Pringles, pumpkin spice doughnuts or anything like that. People also like pumpkin spice latte because it’s caffeine. The Pumpkin Spice Latte is a coffee drink made with a mix of traditional fall spice flavors.
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...
ash was boiled for 5 minute with 25ml distilled water by covering the crucible with a watch-glass on water bath then cooled. The watch-glass was rinsed with 5 ml of distilled water and this liquid was added in to the crucible. The % of remaining content was deducted from initial % of ash taken (i.e. 100%) to determine the water soluble ash value.
The ash content represents the quantity of bran that remained in the flour after milling. Since it is impossible to sep...
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...
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.

Introduction: The purpose of this experiment was to isolate eugenol or clove oil from cloves using steam distillation and determine whether it is an efficient way to carry out this experiment. Also, TLC and 1H NMR were preformed to analyze the purity of the isolated eugenol.

Food Preservation is the ways to retain the food quality in a longer times. It is to prevent the food decomposition and fermentation. Besides that, food preservation not only to prevent the food getting spoilt in a long period of time but also preserved the colour, taste and the food nutritive value. Nowadays, food preservation has become more and more important component in the food industry as the consumers expect that able to purchase those foods that are out of season or imported from other countries. Furthermore, there are few reason why food preservation is important in our daily life such as preservation foods when they are in season it may added variety choices in our meals for example smoke meats and
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.
