Food additives are in most of the things we eat. Most People consume food additives every day in all the foods they eat. There are many additives used that people know about and many that the average person has no knowledge about. This paper will give you a greater understanding which food additives are common and what effect it has on your health. According to the U.S. Food and Drug Administration (FDA)‚ a food additive is any substance added to food. Legally the term means‚ "any substance the

constipation and flatulence. With Lactobacillus acidophilus there wasn’t much about the production of toxins it could cause‚ but more about the detoxing abilities. It aids in producing enzymes which promote digestibility‚ decreases the levels of toxic amines in the blood‚ the positive list goes on. When researching of other bacteria that was closely related to Lactobacillus acidophilus. I was unsuccessful. But because it does grow naturally within us this bacteria works in conjunction with other bacteria

1. Title: The Process of Determining the Unknown Bacteria #9 Rachel Judecki July 5‚ 2011 2. Introduction: Each student was given unknown bacteria and was instructed to perform a variety of experimental tests that would help to identify their bacteria. During the process of identification‚ the unknown bacteria was added to many different testing medias using aseptic technique. They are as follows: lactose fermentation on eosin methylene blue (EMB)‚ TSI (Triple Sugar Iron agar)‚ Phenol

Discuss a range of analytical techniques used for the purification of proteins What are proteins? Proteins are the main building blocks of life. They are essential for the body and have many different roles . Proteins are made from sequence of amino acids. Protein structure is determined by their sequence of amino acids‚ which are linked by peptide link. Proteins are made from about 50 to 2000 amino acid residues. Figure 1 Why purify proteins? They are many reasons why a biochemist

Saccharin is one of the most disputed sugar substitutes in the United States today. Since 1977‚ it has been regarded as potentially carcinogenic ("Saccharin"‚ 1999). The sweetness of saccharin compared to sugarcane is utterly amazing. When measured up to sugarcane‚ saccharin is 550 times as sweet in its pure state. Also‚ it is estimated to have a sweetening power of 375 times that of sugar ("Saccharin"‚ 2000)! This drug may be amazing‚ but some people say that it causes a dangerous disease‚

class that occurs naturally in a variety of plants‚ taking its name from one of the commonest‚ barley (Hordeum species). Chemically‚ hordenine is the N-methyl derivative of N-methyltyramine‚ and the N‚N-dimethyl derivative of the well-known biogenic amine tyramine‚ from which it is biosynthetically derived and with which it shares some pharmacological properties (see below). Currently‚[1] hordenine is widely sold as an ingredient of nutritional supplements‚ with the claims that it is a stimulant of

Neurotransmitters are brain chemicals that transmit information throughout our brain and body. They transmit nerve signals electrically and chemically between neurons. Neurotransmitters can affect mood‚ sleep‚ concentration and weight. The two kinds of neurotransmitters are: inhibitory and excitatory which‚ respectively‚ calm and stimulate the brain. Dopamine is an inhibitory neurotransmitter so when dopamine reaches the receptor sites‚ it blocks the neuron from firing. Dopamine is produced in multiple

Large scale Enzyme applications 1. Detergents Bacterial proteinases are still the most important detergent enzymes. Lipases decompose fats into more water-soluble compounds. Amylases are used in detergents to remove starch based stains. 2. Starch hydrolysis and fructose production The use of starch degrading enzymes was the first large scale application of microbial enzymes in food industry. Mainly two enzymes carry out conversion of starch to glucose: alpha-amylase and fungal enzymes
