Introduction:
Rice (Oryza sativa L.) is among the most widely consumed important staple food worldwide especially in Asia. Rice flour (starch) is one of the primary and major ingredients of various food products. Starch is the major carbohydrate of rice flour. Rice starch consists of two major polysaccharides such as amylose (20-30%) and amylopectin (70-80%).Starch physical and chemical properties with unique functionalities are due to these polysaccharide(Slattery, Kavakli, & Okita, 2000). Amylose is primarily linear molecule with comprises α-1, 4 linked glucose chains and amylopectin is branched which is linearly linked by α-1, 4 linked glucose and α-1, 6 branch linkages. Changes in physico-chemical properties are due to difference in length, degree of branching of these polysaccharides. Due to its unique properties and nutritional role, usage of starch in many food applications is currently increasing. It is widely used as a thickener agent, colloidal agent, colloidal stabilizer, bulking agent and water retention agent(Singh, Kaur, & McCarthy, 2007).Sensory qualities and suitability of specific end products depends upon the

Plasma contains energetic particles such as ions, neutrals, photons and electrons. These energetic particles are effective in modifying starch. An application of plasma then helps initiating cross linking in starch molecules (Zhang et al., 2014; Zou, Liu, & Eliasson, 2004).Starch undergoes depolymerization and Carboxylic groups on surface are formed by low pressure air glow plasma this is due to the formation of reactive species which hydrolyze the chemical bonds therefore cleaves large molecules and formation of dextrins similar to the gamma irradiation and electron beam(Lii, Liao, Stobinski, & Tomasik, 2002a, 2002b; Pimpa et al., 2007) .this might change the physico-chemical
Gareth Williams Background knowledge (facts): Chemicals changed by enzymes catalysed reactions are called the substrate of the enzyme they fit into the active site of the enzyme; this is where the reaction takes place, this happens with a lock and key mechanism. The product of the reaction then leaves the active site, freeing it up for more similar reactions to take place. Amylase is a carbohydrase enzyme which is in our saliva gland, this helps digest the carbohydrates that we eat e.g. pasta and bread etc. [IMAGE] Starch is a large molecule which is made up of lots of other smaller

A major issue that is occurring in America is a phenomena known as “food deserts”, most are located in urban areas and it's difficult to buy affordable or good-quality fresh food. Whereas in the past, food deserts were thought to be solved with just placing a grocery store in the area, but with times it has become an issue that people are not picking the best nutritional option. This issue is not only making grocery store in food deserts are practically useless and not really eliminating the issue of food deserts because even when they are given a better nutritional option, and people are not taking it. In my perspective, it takes more than a grocery store to eliminate ‘food deserts’. It's more about demonstrating the good of picking the nutritional option and how it can help them and their families. For example, “Those who live in these areas are often subject to poor diets as a result and are at a greater risk of becoming obese or developing chronic diseases.”(Corapi, 2014).
In the essay " Rice for Thanksgiving " by Jocelyn Fong who is a full american, partial asian young girl is a young girl who admires her untraditional thanksgiving, and meaning. Fong loves thanksgiving, due to her Grand mothers special dish " Rice and Gravy " as said in the essay Her Grandmother always celebrated the American way, She even never got around to teaching Fong's father their native language. " I believe in rice and gravy, I am half Asian and completely American. " by Fong saying that, she completely accepts the mix she is by referring to the mix of food that is a tradition. You should celebrate holidays the way it makes you happy, with your very own culture regardless the fact if it is different.
Once upon a time there was a turtle named Chunky Rice, who was on a journey to find himself a place where he belongs. After all, a turtle technically always has his house carried on his back doesn’t mean that the place you are at feels like home. Chunky Rice sat looking out into the water on the boat that would take him to his destiny.
Starch, cellulose, glycogen, and chitin are all examples of polysaccharides. According to the BIO 1510 Lab Manual (2016) polysaccharides are not very soluble in water but can be made to go into solution through heating or agitation. Polysaccharides are excellent energy storage molecules because they are easily built and broken down by enzymes. Forming fairly compact structures, polysaccharides allow energy storage without the space required by a pool of free glucose monomers. Other polysaccharides form strong fibers that provide protection and structural support in both plants and animals. (Carbohydrates.” Home,
The primary method to control gestational diabetes mellitus (GDM) is through dietary regulation. The most effective method to control GDM via diet is through carbohydrate restriction and/or selectivity. It is recommended that pregnant women with GDM reduce their carbohydrate intake to 40% of the total caloric intake or can maintain a 60% carbohydrate intake but those carbohydrates must all come from low glycemic index foods. Examples of low glycemic foods are apples, spinach, black beans, split peas, oatmeal, and quinoa. Additional suggestions are to eat complex carbohydrates instead of simple, refined sugars. Eat small, frequent meals and snack often in between meals in order to maintain constant glucose levels throughout the day.
To yield the production of MSG, fermentation process is required by using molasses from sugar cane while starch hydrolysates from corn and tapioca. Subsequently, development of fermentation process has resulted in the production of MSG through hydrolysis of natural proteins, mainly wheat gluten and defatted soybean flakes. Due to th...
Complexity of compounds is the reason they must be absorbed long before the physical activity. Starch a main area of complex carbohydrates. It has several bonds. Starches are tightly bound carbon molecules and have several attaching elements. This bonding complexity is the reason starches are capable of retaining large amounts of energy. These compounds should be taken into an athlete's body prior to intense physical activity because an energy storage supply is necessary when simple compounds are completely oxidized.
Rice (oryza sativa) is the staple food for about one half of the world’s population. This grain has origins going back to about 3000 B.C in India, and grew along the rivers of the Tigris and Euphrates circumscribing the ancient civilizations of Mesopotamia. Rice is the staple food of East and Central Asia, the islands of the western Pacific and much of Latin America. These eastern nations are today the main rice-producing countries; places such as China, India, Japan, Bangladesh, Indonesia, Thailand and Burma. Rice is much more than a grain; it has fueled economies, been subject to science, and traveled the globe due to world trade.
Starch is the predominant carbohydrates source in our diets. The digestion of starch in human starts in oral cavity and involves the enzyme amylase, it is produced by the salivary gland, and it is able to hydrolyze the alpha -1,4 glyosidic linkages in starch. (Tracey 2016) The presence of salivary amylase makes the process of digesting starch to occur in a much faster and efficient manner, since it does not have to wait till the food mixture to get into small intestine to start the breakdown of starch. The variation of this enzymatic activities among individuals are found to be significant. The fact that one individual has a higher concentration of salivary amylase compare to another is found to be somehow related to the starch level of the
Sorghum bicolor (L.), often referred to as grain sorghum, is a grain of global importance (Anderson et al. 1949), because it is a rich source for food, feed, and fuel (Wang et al. 2008). Sorghum ranks fifth in the world for produced cereal crops. In areas that are frost-free, grain sorghum is a very important and economical crop. Sorghum was introduced in North America from the tropical regions of Africa in 1853. It is a very hardy crop that can grow in very tough environments. Sorghum is mainly planted in regions around that world that experience hot and dry conditions. In areas where corn is not very adapted, sweet sorghum is often a better alternative renewal fuel source (SSEA 2014). Sorghum acres have increased over the past 50 years, and the worldwide area of sorghum being planted has risen to 66% (Stroade et al. 2013). The southern US sorghum production often has damage occur from the sorghum headworm complex that consist of two larval pests that included: the corn earworm, Helicoverpa zea, and the fall armyworm, Spodoptera frugiperda (Teetes et al. 2000).
Gluten in semolina is glassy; however, it becomes rubbery and elastic after addition of water. Strands and sheets will be form via inter-molecular bonds and this matrix aids in encapsulate the starch granules in pasta. Irreversible protein-protein cross-links are formed when the hydrated gluten is heated. At below 55˚C, starch will not absorb water. During heating, starch begins to lose its structure, becomes rubbery passing its glass transition and can absorb water readily. (Sissons
Burmese food is influenced by that of India and China, but it has its own specificity. In addition to Burmese food, other traditional ethnic foods such as Shan food, Rakhine food and Myeik food are also different. Rice is the core of Burmese food, and good vegetarian food is widely available. Burmese food is usually extremely spicy. Similar to the neighboring countries of Southeast Asia, fish sauce (ငံပြာရည် ngan bya yay) is a very popular condiment in Myanmar, and is widely used to flavor many dishes. Food is cheap at most restaurants (priced at MYK 500-3,000 per item at most local restaurants, but can go up to 8,000 MYK at posh restaurants). There are many luxury restaurants in Yangon and Mandalay.
