This is known as salivary cortisol testing‚ which can collect fluid from the sublingual‚ parotid‚ and submandibular salivary glands. The levels of cortisol are measured through the alpha amylase‚ which spikes due to stress. Salivary cortisol sample collection is non-invasive and salivary amylase measurement is an accurate tool for stress assessment (Lai‚ 2005). The behavioral method one could employ to measure

PROTEIN Prior to completing the lab experiment‚ it was predicted that whipping cream‚ soy milk‚ and the flour solution would all contain proteins. Looking back at the collected observations it can be concluded that the hypothesized statements were all deemed accurate. However‚ corn syrup was the only substance that did not test positive for proteins. This abnormality was researched‚ and it is now clear why only three out of the four substances tested positive for proteins. To start‚ it was hypothesized

Treating starch How is starch and cellulose treated to allow them to be used by the yeast? (1)Starch is a complex carbohydrate that is insoluble in water. It is supplied by traditional staple foods such as cereals‚ roots and tubers. Starch is used in cooking for thickening foods such as sauce. In industry‚ it is used in the manufacturing of paper‚ textiles and as a mould in the manufacture of sweets such as wine gums and jelly beans. Fermentation (2)As with any food preparation‚ there are

Test #1 * Add a small piece of cracker in test tube #1 and add Lugol’s solution. Observation #1 * The cracker turned a black colour when the Lugol’s solution was added to it. This was a positive result‚ meaning that the cracker contains starch. Test #2 * Add a bigger piece of cracker in test tube #2‚ add 5 mL of Benedict’s solution‚ place in a boiling water bath‚ and record observations after 5 minutes. Observation #2 * There was no change in colour after the Benedict’s solution

pieces so that i can fit down the throat. As the teeth do their work‚ saliva mixes with the pieces of me‚ making me soft and moist. The saliva contains a chemical called salivary amylase‚ which starts breaking down complex carbohydrates‚ and another called mucin‚ which helps to soften the food. The amylase enzymes turn the starch molecules found in me into glucose. The glucose is used by cells to give people energy. oklahoma4h (2015) ptonthenet (2015) bbc.co.uk (2015) The tongue which is a muscle

If carbohydrate is present in starch suspension‚ the solution will turn into dark blue when iodine solution is added. If carbohydrate is present in potato cell‚ starch granules can be seen clearly under microscope when iodine solution is added. The second experiment is to test the existence of lipids in margarine and
