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

lingual lipase. Amylase breaks down dietary carbohydrates such as monosaccharides‚ disaccharide sugars and complex polysaccharides (starch). Monosaccharide’s can be easily absorbed into the bloodstream so the others need to be broken down into these before they can be absorbed (Derrickson‚ Tortora 2006 p906). The salivary amylase starts to break down the polysaccharide starch found in the bread of sandwich and the rice in the chicken Tikka meal while it is being chewed. Once the food has been swallowed

kinds of biodegradable plastic‚ including polyesters‚ polyhydroxybutyrates‚ vinyl polymers and starch-based polymers. [Garthe‚ James W.‚ and Paula D. Kowal] In this essay‚ the use of plastic made from polylactic acid or PLA (a kind of starch-based polymer) will mainly be discussed‚ because they are one of the most commonly used and cheapest-costing of all biodegradable plastics. PLA is made from the starch in corn (or sometimes wheat) plants‚

Roll it flat with a rolling pin. Place into a dish on top of each other‚ with corn starch in between to prevent each piece from sticking to each other. * Step 5: Pick some fillings prepared before and put at the center of the wrapper (less filling should be put if you are a green hand). Fold and pinch the wrapper from the middle to

Infographic Project Enzymes are organic catalysts produced by living organisms which aid in the progression of specific biochemical reactions without undergoing any permanent chemical changes themselves. They are complex‚ conjugated proteins necessary and required to sustain life. Today‚ enzymes are also used world-wide in a variety of different industrial applications such as the production of paper‚ wine fermentation‚ and bio-remediation. One of the most important industrial applications

Sugar levels in existing Kellogg’s Coco Pops cereals will be cut by 15% by the middle of next year and replaced with starch from grains and glucose syrup. No artificial sweetners will be added and the calorie count will remain the same – around 116 per portion. Kellogg says the move will cut sugar consumption in the UK by 750 tonnes‚ with 29 million boxes sold annually
