Why are grain products essential to your diet? How do you cook rice? Pasta? What is a Leavening Agent? What is a Quick Bread?
3
Often called CEREALS All plants in the GRASS family are grains List some grains that are familiar to you. (Wheat, corn, rice, oats, rye, barley, buckwheat, millet) Grain products produce many small, separate dry fruits called KERNELS. (FYI: because grain kernels called fruits, grains are sometimes called berries, as in wheat berries)
4
Kernels are harvested and processed for food. Three parts of the grain: BRAN- (protection for seed) outer covering that is rich in nutrients (B vitamins and minerals) as well as provides fiber ENDOSPERM-(energy for seed) Inner part, mostly starch, largest part. This part is used for making white flour. Low in vitamins and minerals. GERM-(nourishment for seed) heart of the kernel, found at one end. Part from which new plant sprouts. Nutty flavor
6
Carbohydrates-2 forms A. Starch-body energy, ¾ of the cereal consist of starch. B. Fiber(cellulose)- Regularity, found in the bran.
7
Vitamins B Vitamins Thiamine- growth, appetite, nerves, coordination Riboflavin and Niacin- nerves and digestive tract Minerals Iron- red blood cells Phosphorus- bones and teeth. (Bowl of cereal good because you have the milk and phosphorus needs calcium.)
8
Protein Incomplete- How can you get all the amino acids you need, what can you put together with the incomplete proteins. Fat Found in the Germ
9
Products that are not whole grain have been refined. The bran and germ have been removed, leaving only the endosperm. Nutrients are lost during this process Products: White Flour, White Bread and many breakfast cereals. Whole grain products the entire kernel is used.
10
Most people prefer white bread over whole grain. “Bread Enrichment Program” initiated in 1943. Some of the nutrients lost in milling are added back to the product so the end product is close to the original. (Milling- Refining and grinding process) Whole wheat bread and enriched white bread are close with the nutrition, but whole wheat has the fiber.
11
RICE- White rice- bran and germ removed, comes in short grain, medium grain and long grain. Converted rice- Parboiled to save nutrients before hull is removed. Brown rice- Whole grain form OATS- Usually eaten as a cereal, can get quick cooking oats. CORNMEAL- Coarsely ground dried corn. Yellow or white. Used in breakfast cereals and in baked goods.
12
GRITS- coarsely ground endosperm of corn. Used as breakfast cereal or a side dish. WHEAT BERRIES-whole unprocessed wheat kernels- cooked as cereal or added to other foods. CRACKED WHEAT- very hard with tough and chewy texture. Added to bread.
13
What is a leavening agent? Leaven means to make light or force to rise by producing a gas, carbon dioxide. A Leavening agent is an ingredient that helps baked products rise.
14
1. Air- Expands when heated. trapped in a mixture by sifting flour, creaming a fat or sugar, or beating egg whites and batter. Oven heat makes air expand and product rises. What kind of baked products use air as a leavening agent? Angel food cakes, sponge cakes
15
2. Steam- produced by heating liquid in the batter Product must contain a relatively large amount of liquid. High baking temperatures used. Combination of water and heat creates steam which makes it rise. What types of baked products use Steam as a leavening agent? Popovers and cream puffs
16
3. Chemicals- When mixed with a liquid, the chemical gives off carbon dioxide, heat make the carbon dioxide expand. Baking Soda- must be mixed with an acidic food, such as buttermilk or sour milk. Baking Powder- is a combination of baking soda and dry acid. Quick breads, cakes, cookies are examples of this type of leavening agent.
17
4. Yeast- microscopic plants Needs food (sugar), moisture (water), and warmth to grow. As yeast grows, it gives off carbon dioxide. Heat makes carbon dioxide expand and product rises. What kinds of baked products use this type of leavening agent? Breads, pretzels, rolls, doughnuts
18
Because they are dry, they must be cooked in water. (need enough time to absorb the water) Cooking times and methods vary, follow the package directions. Unless the package tells you otherwise, DO NOT RINSE enriched grains before cooking, it will cause a loss of the added B vitamins Microwaving: not practical because the grains, especially pasta, need time to absorb the liquid and soften.
19
Triples in size. Usually simmered in just the amount of water the grain can absorb. (ex white rice—2cups water to 1 cup rice) Cooking Directions: 1. Boil water 2. Add rice 3. Cover and boil again 4. Simmer gently
20
How to determine when it is done Should be tender but firm Should not have water left (cook without cover until no water remains) Instant rice- follow package directions
21
Doubles in size Boil water in pot large enough to accommodate pasta and boiling action Add pasta, stirring, keep boiling. (Boiling helps the pasta circulate so it cooks evenly) Cooking time depends on thickness of pasta- fresh pasta cooks faster than dried Cook until al dente- firm to the bite, not mushy
22
Drain in colander, NEVER RINSE, it will lose valuable nutrients To keep hot, set colander over pan of hot water and cover. Pasta can be frozen after sauce is added.
23
Use plenty of water Add pasta slowly so water keeps boiling Stir frequently during cooking Add small amount of oil in water. Pasta is generally low fat and low calories- high in protein and carbohydrates. Sauces are what add fat and calories.
24
2 types 1. Batters- mixtures that have been beaten Pour batters- pancakes Drop batter- cookies 2. Dough- stiffer mixtures that can be handled Soft- biscuits Stiff- pie crust
25
1. Flour- forms structure or body of the product. Gluten gives strength and elasticity 2. Leavening Agent- Enables the product to rise 3. Salt- In small amounts, improves flavor 4. Fat- provides tenderness (shortening, butter, margarine) 5. Liquid- (often milk) converted to steam- provides some of the leavening action
26
6. Eggs- color and texture 7. Sugar- Sweetness and brown color
27
Major concern is gluten development (gluten- flour protein) Over mixing and too much handling results in a large amount of gluten being developed and breads become tough. Quick breads require little mixing and careful handling to avoid the overproduction of gluten.
28
1. Muffin method- for batters, sift or mix dry ingredients into bowl, beat eggs in separate bowl, measure liquids into separate bowl. Pour liquid ingredients into center of dry ingredients called a well. A few flour spots can remain and the batter should be lumpy. Fold extra ingredients in like blueberries and raisins in gently. Result: Perfect muffin- rounded, golden brown, pebbly surface. Over-mixed- peaks at the top, heavy and tough, and tunnels inside
29
2. Pastry and Biscuit Method- Sift together or mix dry ingredients. Sifting ensures that the ingredients are distributed evenly Cut fat into dry ingredients until the particles are the size of peas or coarse bread crumbs. Make a well in center of dry ingredients and add the liquids just until blended.
30
Knead- to manipulate dough by rolling it forward and folding it back with the heel of the hand. Gluten- an elastic substance formed from the protein in flour when flour is mixed with water- gives structure to baked product. Cut-in- To divide finely and distribute a solid fat by cutting with a pastry blender or two knives. Leaven- to make light or force to rise by producing a gas.
