Maize (sweet corn) is the third most important cereal in the world. Asia consumes more than 62% of its maize production in the form of animal feed and remaining for human consumption. Sweet corn is one of the most popular vegetables in the USA, Canada and Australia. It is becoming popular in Malaysia and other Asian countries. Sweet corn differs from other corns (field maize, popcorn and ornamental) because the kernels have high sugar content in the milk on early dough stage. It is consumed in the immature stage of the crop. The kernels of sweet corn taste much sweeter than normal corn, especially at 25-30%. The quality and level of sweet corn depends on the type of gene involved for sweetness.
Modern technologies of sweet corn harvest and

An especially important factor that determines the mechanical properties of seeds and kernels is their moisture content. Moisture is a fundamental factor affecting changes in the mechanical strength of the involucres. Moreover, moisture is the basic factor determining the character of deformation that seeds undergo when subjected to loads. In numerous studies, mechanical properties are determined by means of compression tests under quasi-static conditions. In such tests, the speed of the loading element usually does not exceed the value of 0.005 m•s-1. In practice, however, in many cases we have to deal with dynamic loads and high deformation rates. Young modulus (modulus of elasticity) is one of the fundamental mechanical properties of grain. It expresses the relation between stress and strain of a body subjected to loading. Its value depends on the chemical composition and on the mechanical structure of the grain and on the rate of deformation and value of the load applied.

Corn subsidies are driven by the major food and gas companies in our country that want to dictate what food we put in our plate and what fuel we put in our cars. The companies can do this because of the artificially low price tag on the items they sell because of the cheap cost to produce corn. The only concern for the major corporations is to please their respective shareholders by delivering high profits. They are certainly not concerned with the health of the consumer or the environment.
The process by which high fructose corn syrup is made is complicated. To start, ordinary corn syrup must be obtained. Then, enzymatic processes increase its original sweetness. To produce the basic un-enhanced corn syrup, wet milling is a commonly used technique. Wet-milling includ...
In conclusion, corn has come a long way since its first domestication. It began as a prized possession to the Natives as they worshipped corn goddesses and had steady rituals allowing them to receive the corn and give thanks for the corn. The views for the United States seem to be produce as much as possible – and profit from it. China and Hungary aim to produce corn as well but limit themselves to unmodified corn. Although all the groups previously mentioned have/had their own way of viewing corn, one thing is for certain: corn is a popular plant and is presently essential to our lives.
High Fructose Corn Syrup is found in a lot of the foods and drinks we consume. It is something that is consumed on a regular basis by not only Americans but by plenty of others across the world and sometimes we might not even note the difference between it and “real” sugar. HFCS comes from a type of corn known as “Dent” corn, dent corn is transformed into cornstarch by being cleaned, soaked, ground, milled, and dried corn starch is then converted into a liquid state in a process known as hydrolysis (Sloan, 2013). Once in a liquid state, HFCS is then used to not only add a sweet flavor to drinks and food but it also can be used as a form of coloring to the consumables. What you would label as “regular” sugar is essentially the same the same thing as HFCS when you break them down chemically, the only difference between the two is that their chemical components are placed in different order (Beil, 2013).
WHEN Zhang Yimou made his directorial debut, Zhang Yimou made his directorial debut, Red Sorghum, in 1987, he was better known as a cinematographer whose talent had been crucial to the success of critically acclaimed films like Zhang Junzhao's One and Eight (1984, released 1987) and Chen Kaige's Yellow Earth (1984). Not only did Red Sorghum become a seminal film of the Fifth Generation, it also won the Golden Bear at Berlin in 1988, becoming the first mainland Chinese film ever to be awarded the highest honour at a major international film competition.
out of the needs to grow more items for consumptions. Utilizing flat land that was later layered, this process allowed for underutilized land to be used for more sustainable, alternative food resources. Corn was also another large aspect in the religion of many in the Americas. Wither it be the Mayans and their creation myth surrounding the god Popol Vuh , or the Aztecs and their reverence for the sun god Centeotl many of these indigenous groups saw corn as the very reason of their existence, and would go to great lengths in order to help proliferate these stories throughout their various empires. An example of this proliferation was done by the Pochteca, a class who Aztec merchants who acted on behalf of the state who would use it as a form
Given the amount of resources that the world as a whole has access to why use corn as a source of fuel? Some would say that countries, such as the United States have an overabundance of food produce. Logically, those countries that have an over surplus of food MUST have enough to put a dent into the rapidly increasing costs of oil and gasoline. Unfortunately, that is a misconception. In order to produce enough corn to fuel the global economy it is important to analyze what that actually means for farmers and the government, not to mention the actual food supply. In order to produce corn ethanol, we must first grow an abundance of corn. Simple right? Wrong, corn is very draining on the soil it is grown, which, in short, means that whomever is growing the corn would have to rotate the corn plantation with something that will restore the nutrients of the soil. Unfortunately, that takes both time and money to do. The task would cal...
Selling corn in massive quantity can lead to a greater profit. An ear of corn may averages about eight-hundred kernels in sixteen rows and a pound of corn consists of approximately 1,300 kernels. One-hundred bushels of corn makes approximately 7,280,000 kernels. Every year, a single U.S. Farmer may provides food and fiber for 129 people in the U.S. and 32 overseas. In the U.S., corn production is 2 times that of any other crop. Over 55% of Iowa’s corn goes to foreign markets and the rest is used in other parts of the United States of America.
One of the most successfully crops was traded from the Americas to Europe. Once corn arrived in Europe it was used as animal fodder, but the value of corn as human food proved itself. Corn has been one of the stimulants to population growth in the ‘old’ world. It helped to improve diets by providing much needed nutrition and calories.
Determining the Concentration of the Cell Sap in Potato Storage Tissue Aim: To determine the concentration of the cell sap in potato storage tissue. By using Osmosis, determine what the sugar concentration of cell sap is. Prediction I predict that the potato segment in the distilled water will definitely gain in weight because the solution outside it has a much higher concentration of water then in the cell sap meaning Osmosis will occur and the potato segment take in water. I predict that 0.2M sugar solution will also gain weight because it still has quite a high concentration of water outside the potato. The potato in the 0.4M solution will gain weight but the potato in the 0.6M and 0.8M solutions will lose weight.
Throughout the history of the human race there have been a great number of crops that were discovered, planted, and over time domesticated. Wheat in the Middle East, rice in Asia, and rye in Eastern Europe are all some of today’s staple crops that feed millions every day. Crops like these make up over 50% of the world’s total food supply. However, the third most eaten crop in the world is maize, or corn, which provides 21% of human nutrition. Today maize feeds millions across the world, but its history is different from the others.
Since the plant’s domestication the sunflower has been one of the most important crops in production that is native to North America, comparable to maize and wheat. The sunflower, what was once a plant utilized only in the Americas is now one of the most widely and diversely recognized used plant species in the world.
This lesson is designed to review and reinforce a few important concepts about plants (e.g. Needs, parts, sequence of planting) and to also guide the students through applying a few scientific inquiry (e.g. Making observations, experimentation, discussion, reflection, reporting results etc.). The students have previously planted corn and bean seeds and today’s lesson has provided the students a chance to see the results of the planted corn and bean seeds. Additionally, seeds have been planted under and growing under the following conditions: without water, and without soil. The students see the results of these seeds planted under these conditions for the past week. Two plants in particular have already been grown their growth has been
Sweet potatoes are a vegetable in the Convolvulaceae family, signifying that it is a vine, funnel shaped flower, and bisexual plant. Its botanical name is Ipomoea batatas. Sweet potatoes are also assimilated with “yams” in the United States; this is because of its orange-flesh. (Encyclopedia Britannica, 2013)
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).
