Smoking is the processed of putting the meats to the smoke of a charcoal or wood fire for cooking. The purpose of smoking meats are adding brown colour to it, enhance its flavour and prevent the growth of microorganisms. The chemicals that formed during smoking or cooking the meat using high temperature are heterocyclic amine (HCA) and polycyclic aromatic hydrocarbon (PAH) (Butler 2003). These two chemicals are mutagenic and can cause changes in DNA which lead to cancer. HCA is formed during the reaction between heat and amino acids and creatines (both found in meat).
Both of these processes generate heat- and the combination of the heat and acid kills the cocoa bean. When the cocoa bean dies the cell walls are broken down and the enzymes created by the yeasts are allowed in. These enzymes induce chemical changes in the substrate- the cocoa beans- that give the chocolate its flavor and color. At the same time, the acid produced by the bacteria has reached the bean, and it lowers the bean’s pH, giving it a sharp, tart flavor. Later, the acid vaporizes and leaves the bean during the roasting process, which we’ll talk about in the next paragraph.
The art of roasting is a technique that has been used for centuries. Even back before modern cooking techniques, people roasted food over open fires. Today, roasting is achieved by enclosing the item in a dry, hot, smoky environment. Usually, large meat that could feed many is commonly roasted, whereas smaller foods, like portion sizes, are baked. Roasting is common when the chef seeks a classic, meaty flavor.
Soil, rainfall, and climate are factors that would have the potential to alter a plant. The author questions rather the Naga King Chili would be hotter if it were grown in an area with different growing conditions.

Concluding paragraph: The article was talked about the science behind hot peppers like that of the Naga King Chili. Capsaicin can be very hot and intolerable, and even harmful to the human body.
Not only does barbecue taste good but it helps bring people together to enjoy a special occasion or to just have dinner together. In this essay I will give a general definition of barbecue, tell a brief history on it, discuss the various styles of it, and explain why it’s so popular in the South. What is barbecue? According to the Merriam Webster dictionary the term “barbecue” has multiple definitions .The first definition that we are most familiar with is; to roast or broil on a rack or revolving pit over or before a source of heat. The second definition is the social gathering especially in the open air at which barbecued food is eaten (Merriam Webster).
To begin,Chemistry is what created other sciences like biology and geology. You can find chemistry in everyday life. For example at school when you're doing an experiment and a chemical reaction occurs that's chemistry. Right now in the present China is exploring and discovering new things in the art of chemistry. Each day they are working on many projects that will both improve the Earth and will keep it spinning.
Therefore; the objective of this essay is to demonstrate step by step how anyone dealing with this issue can make a perfect barbecue. First, gather the materials and accommodate yourself in your working area. The materials needed are a grill, brisket, sausages, chicken, tortillas, seasoning, salsa, firewood, and a lighter. The amount of the food depends on the amount of people’s servings. Other materials needed would be cooking utensils, such as tongs,
The froth is produced due to the gas as it bubbles from the potato slice. This gas is given off as a waste product from the reaction where H2O2 (substrate) breaks down the enzymes in the potato. If I were to roughly plot a graph for the reaction, it would look like this, [IMAGE] The graph shows that as the concentration of hydrogen peroxide is increased the more oxygen is given off. This is because there is more hydrogen peroxide to be broken down by the enzyme and with more hydrogen peroxide in the reaction, more oxygen is released.
Question: What is the effect of acids and bases on apple oxidation? Background Information: Apple discoloring, is the process of the skin turning brown when bruised and exposed to air. The browning is due to oxygen, O2, reacting with chemicals which breaks down the cells in the fruit. The reaction is called enzymatic oxidation a process that is started by the enzymes that are present in the apples which starts the browning process of the apple. However, the enzymes are quickly destroyed by chemicals or by high heat.
When exposed to certain wavelengths of light, photosensitizers such as riboflavin gets into an excited state and in turn, react with a ground state molecular oxygen (Huvaere et al. 2010). The reacted oxygen then starts a cascade of energy transfers at which an oxygenated molecule such as hexanal is produced as the end result (Decker, Elias & McClements 2010). The oxidation of unsaturated fatty acids then causes an off-flavour to form in the cereal which is undesirable to consumers (Saunders 1990). Explain the principles of the food preservation methods
