This formally is called an allergy. Antigens that cause allergy are called allergens, and some examples are ragweed pollen, poison ivy and can be certain food proteins (9). In the case of food allergy, the allergen is the food protein that causes an exaggerated immune response. To develop a particular food allergy, the person must first be exposed to the allergen or food protein. This initial exposure causes sensitization and it is the subsequent exposures that elicit the damaging immune responses that is recognized as the disease.
E. coli has even been used to synthesize human insulin. Other strains are pathogenic, causing diarrhea, urinary tract infection and even fatal illness. Unlike some bacteria, E. coli cannot tolerate harsh environments, and instead thrive at 37°C. The primary goal of this experiment is to examine the growth of E. coli on bacterial lawns in order to determine expired mouthwash’s efficiency as an antibacterial product. Since it is expired, the mouthwash should not perform well as an antibacterial agent.
A con is the higher risk of destruction of normal body flora. Drug allergy, drug toxicity, and creation of resistant microorganisms are also facts that need to be taken into consideration. Narrow-spectrum antimicrobials can only target either Gram-negative or Gram-positive microorganisms or a small variety of microorganisms at the time used. A con is that the bacteria have to be indentified first, before treatment can start. The pros are the reduced risk of creating resistant microorganisms and less chance of harming the host.
The Millard reaction is formed in the presence of sugar and amino acid. Millard reaction takes place in living organisms and also are health beneficial acting as an anti-oxidative, and antibiotics. They also help in the promotion of diabetics, and cardiovascular diseases an example of this MRPs is carboxymethyl lysine (CML), and acrylamide acting as a carcinogen. It was reported that people that eat instant meal such as pizza, snacks, and processed meats tend to have developed insulin resistance, and metabolic syndrome more than those that eat low processed foods, and vegetables. Millard reaction products changes while processing foods, and they are important either in the increasing or fighting of diseases.
Because they are already busy absorbing and neutralising the free radicals from cooking (in the case of frying) or leaching into the water (in the case of boiling). Steaming and microwaving tend to retain more of the antioxidants than frying and boiling. The ORAC may go down a notch when steaming and microwaving, as you’ve seen in the raw vs. steamed spinach example (Module 8, slide 23), where the raw spinach has a higher ORAC. Now, even if a food has a higher ORAC (e.g. raw spinach), it doesn’t mean that your body will be able to absorb and assimilate 100% of the antioxidants in it!
When electrons hit an impurity it doesn’t fly off in a random direction. Electrons move freely through the complex lattice. Where there are no collisions, no friction is created; this allows them to transmit a current with no loss in current or energy.5 As the current is increase, the vibration of electrons also increase which increases the heat. However if the environmental temperature is controlled, and is made colder there is less vibration. With few atomic vibrations, it was first predicted that the electrons would pass more easily, however this is all dependent on temperature, and doesn’t fully explain superconductivity.2 The advancement in understanding superconductivity was in the late 1950’s by three physicists; John Bardeen, Leon Cooper, and John Schrieffer, through their Theories of Superconductivity, known as the BCS Theory.
Though most of the foods created may seem extremely unhealthy and perhaps dangerous to ingest. With chemicals called xanthan gum, carrageenan, alginate, agar-agar, and maltodextin and lab equipment like pH meters, tabletop distillers, and water bath machines the worries are well disserved. The reality of it is that the food is safe to eat and isn’t very bad for you most of the time. The chemicals used in molecular gastronomy are all of biological origin. Though they are purified or processed, they were at one point marine, plant, animal, or microbial.
Improper food handling, preparation or storage can cause food to become contaminated with bacteria or germs that could result in illnesses. The other methods for sanitation requirements are to practice good personal hygiene, store foods properly and handle foods in a safe and sanitary manner. The next step is food storage. The way food is stored has a profound effect on quality. If stored incorrectly, food will lose quality and can also allow harmful organisms to grow.
Sanitizing is the treatment of a clean surface with a chemical or physical agent (e.g., heat) to reduce microorganisms that cause disease and/or spoilage to levels considered safe for public health. Sanitizing a food contact surface must reduce the population of specific bacteria by 99.999 per cent in 30 seconds. FOOD SANITATION – PROTECTION FROM CONTAMINATION The word “sanitation” is derived from the latin word “sanitas” meaning “health”. Food Sanitation is the creation and maintenance of hygienic and healthful conditions. Food sanitation is the application of science to provide wholesome food processed, prepared, merchandised and sold in a clean environment by healthy workers; to prevent contamination with microorganisms that cause food borne illnesses; and to minimize the proliferation of spoilage microorganisms.
