Three Sisters Garden One of the Best Ways to Get Children Interested in History Is to Bring It Into the Present
Three Sisters Garden One of the best ways to get children interested in history is to bring it into the present. When teaching children about Native Americans in U.S. history, an excellent project is to grow the three Native American sisters, beans, corn and squash. When you plant a three sisters garden, you help to bring an ancient culture to life. Let’s look at growing corn with squash and beans. The story of the three Native American sisters The three sisters way of planting originated with the Haudenosaunee tribe. The story goes that beans corn and squash are actually three Native American maidens. The three, while very different, love each other very much and thrive when they are near each other. It is for this reason that the Native Americans plant the three sisters together. Tips on how to plant a three sisters garden First, decide on a location. Like most vegetable gardens, the three Native American sisters garden will need direct sun for most of the day and a location that drains well. Next, decide on which plants you will be planting. While the general guideline is beans, corn and squash, exactly what kind of beans, corn and squash you plant is up to you. For the beans, you will need a pole bean variety. Bush can be used, but pole beans are more true to the spirit of the project. Some good varieties are Kentucky Wonder, Romano Italian and Blue Lake beans. The corn will need to be a tall, sturdy variety. You do not want to use a miniature variety. -
Effect of Alkaline Soaking and Cooking on the Proximate, Functional and Some Anti-Nutritional Properties of Sorghum Flour
AU J.T. 14(3): 210-216 (Jan. 2011) Effect of Alkaline Soaking and Cooking on the Proximate, Functional and Some Anti-Nutritional Properties of Sorghum Flour Ocheme Ocheme Boniface and Mikailu Esther Gladys Food Science and Nutrition Department, Federal University of Technology Minna, Nigeria E-mail: <[email protected]; [email protected]> Abstract The effect of nixtamalization on the functional, proximate, and anti-nutritional properties of sorghum flour was studied. Flour samples were produced from soaked sorghum grains and cooked sorghum grains. A portion of sorghum grains were soaked in water and 1% lime solution for 24 hours and some were cooked for 30 minutes in both water and 1% lime solution. At the end of soaking and cooking, the grains were sundried; milled; sieved with a 0.25 mesh screen; and packaged. Alkaline cooking of sorghum resulted in flour with significantly higher protein; water and oil absorption capacity; pH; hygroscopicity; phytate and trypsin inhibitor and significantly lower ash; tannins and cyanide content than flours from untreated and water treated sorghums, while alkaline soaking resulted in flour with significantly higher carbohydrate; water and oil absorption capacity; and pH and significantly lower packed bulk density and hydrogen cyanide than flours from untreated and water treated sorghum. Keywords: Nixtamalization, functional properties, anti-nutritional properties, soaking, cooking. Introduction Unleavened bread (tortilla) is a common food in central and South America produced from Nixtamalization refers to a process of sorghum cooked in lime solution (Asiedu preparing maize (corn) in which the grain is 1989). In nixtamalization, dried cereal grains cooked and soaked in alkaline solution, usually are cooked in an alkaline solution at or near its lime solution, and then dehulled (Ocheme et al. -

Corn Has Diverse Uses and Can Be Transformed Into Varied Products
Maize Based Products Compiled and Edited by Dr Shruti Sethi, Principal Scientist & Dr. S. K. Jha, Principal Scientist & Professor Division of Food Science and Postharvest Technology ICAR-Indian Agricultural Research Institute, Pusa New Delhi 110012 Maize is also known as Corn or Makka in Hindi. It is one of the most versatile crops having adaptability under varied agro-climatic conditions. Globally, it is known as queen of cereals due to its highest genetic yield potential among the cereals. In India, Maize is grown throughout the year. It is predominantly a kharif crop with 85 per cent of the area under cultivation in the season. The United States of America (USA) is the largest producer of maize contributing about 36% of the total production. Production of maize ranks third in the country after rice and wheat. About 26 million tonnes corn was produced in 2016-17 from 9.6 Mha area. The country exported 3,70,066.11 MT of maize to the world for the worth of Rs. 1,019.29 crores/ 142.76 USD Millions in 2019-20. Major export destinations included Nepal, Bangladesh Pr, Myanmar, Pakistan Ir, Bhutan The corn kernel has highest energy density (365 kcal/100 g) among the cereals and also contains vitamins namely, vitamin B1 (thiamine), B2 (niacin), B3 (riboflavin), B5 (pantothenic acid) and B6. Although maize kernels contain many macro and micronutrients necessary for human metabolic needs, normal corn is inherently deficient in two essential amino acids, viz lysine and tryptophan. Maize is staple food for human being and quality feed for animals. -
Different Types of Corn There a Various Types of Corn and They All Have Different Purposes and Distinguished Traits
Different Types of Corn There a various types of corn and they all have different purposes and distinguished traits. Read about the 5 different types of corn and write a 5 paragraph essay on what type of corn you would want to grow. Make sure you do your research! Dent Corn: This type of corn is often used for livestock feeds, industrial products, and as well as used to make processed foods. Another name for dent corn is “Field Corn”. This type of corn is mostly grown in the United States. This corn is a mix of hard and soft starches that become indented when the corn dries out. Flint Corn: Also known as “Indian Corn” is very similar to Dent Corn. They have primarily the same purpose as dent corn, but in the United States its main purpose is decoration. Flint Corn is primarily grown in Central and South America. It has a hard outer shell and the kernels are a variety of colors from red to white. Popcorn: Popcorn is a type of Flint Corn, although it has it has different size, shape, starch level, and moisture content. It has a soft starchy center surrounded by a very hard exterior shell. When popcorn is heated, the natural moisture inside the shell turns into steam and builds up enough pressure until it explodes. Sweet Corn: Also known as “corn on the cob”. This type of corn you will find at your summer BBQ’s and you love to enjoy it with a burger on a hot summer day. This type of corn can be canned or frozen for future consumption. -

Who Doesn't Love Fresh Corn on the Cob in the Summer?
Corn Ahh - who doesn’t love fresh corn on the cob in the summer? It is so good, and so good for you! It not only provides the necessary calories for daily metabolism, but is a rich source of vitamins A, B, E and many minerals. Its high fiber content ensures that it plays a role in prevention of digestive ailments. Growing info: We're expanding our sweet corn production this year by popular demand. The issue with corn, is it takes a lot of space. You can get about 100 ears from every 100 row-feet of planting. When a share consists of 8 ears of corn, this is 8 feet for one share! We plant corn in succession starting in mid May. This will give us a constant supply through summer. Common Problems: Corn ear worms are the TIPS: major pest we deal with in corn. They are tiny little worms that crawl into the tip of the ear and Short-term Storage: Corn converts it's start eating. By the time they get an inch down sugars into starch soon after peak the tip of the ear, they will have grown to a large ripeness, so best to eat it soon. and ugly size. We prevent ear worm by injecting Otherwise, store in a very cold a small amount of vegetable oil into the tips refrigerator. before the worms have a chance of crawling in. Long-term Storage: Cut kernels off the cobs and freeze. You’ll probaby see mostly white corn in 2011.
