IDLY SCIENCE REASONS FOR IDLY AND DOSAI MAAVU NOT GETTING PROPERLY FERMENTED 1) Both batters need Bio activity. So if there is not enough bacteria/Fungus/Yeast present in the batter‚ the maavu will not ferment or will not ferment properly. 2) If you are using chlorinated‚ Iodised water or bacteria free water or Ozonized water in your house‚ you will not be able to get proper fermentation in batter as all these chemicals have residual disinfection property.(except Ozone) . 3) If

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

both germinating pea seeds and crickets. 3. Perform an investigative study of the rate of cellular respiration in both pea seeds and crickets at various temperatures. 4. Compare the alcoholic fermentation of glucose‚ sucrose‚ and starch by yeast. Introduction All organisms must have a continual supply of external energy in order to maintain bodily functions and to combat entropy. Ultimately this source of energy is the sun. As you learned in the previous lab‚ plants can convert the

MICROBES AND FOOD – A ‘RELATIONSHIP’ Microbes and food have always had a love-hate relationship. Food producers have learned to harness their power -- and sometimes for good use. There is no doubt that organically grown fruits and vegetables are superior in flavor. Now‚ despite arguments to the contrary made by food manufacturers‚ they may well be more nutritious for a variety of reasons. There are always studies available to prove any point‚ especially one

Complete creative control (more of an art than a process) - More enjoyable - You choose your supplies/chemicals: fruit‚ specific yeast etc. III. Equipment Needed… a. Carboy - good for fermentation as well as aging b. Hydrometer -used to determine the alcohol level and specific gravity of the wine c. Thermometer - wine has to be a certain temperature to ferment (not too

Lab: Growing Yeast This experiment will take two days to complete. Background Information: Yeast is a very important group of fungi. The common yeast used in baking bread grows very fast. The basic idea in this lab is that the yeast will use an energy source and in doing so‚ will produce carbon dioxide gas. You’ll measure the amount of carbon dioxide (CO2) released during the growth of yeast. The growth of the yeast stops when the energy source has been used up by the yeast and CO2 production

How does temperature affect the fermentation of yeast? In science‚ we stretched a balloon over the top of a bottle filled with sugar‚ warm water‚ and dry yeast. It inflated a little after a few minutes. We did the same thing with another bottle filled with sugar‚ cold water and dry yeast. The balloon didn ’t inflate. Apparently fermentation occurs more in hot temperatures than in cold. Why is this? Chemical reactions within yeast are facilitated by enzymes‚ which are large organic catalysts. Each

ALCOHOLIC BEVERAGES (C2H5OH) Alcoholic beverage is portable liquid which contain 2% to 75% of liquor. They are produced by the introduction of yeast for fermentation into substance such as fruits‚ cereal (grain)‚ molasses and plant extract. Technically‚ it is known as ethyl alcohol that forms as the product of a chemical reaction in which yeast converts the glucose present in the cereals or molasses into alcohol & carbon dioxide(CO2)‚ though there are other reaction taking place at the same
