how can i test sugar?

Fehlings solution is used to test for sugar.  Try a diabetic dipstick.

Benedict's reagent can be used to test for the presence of glucose in urine. Glucose found to be present in urine is an indication of diabetes. 5.0ml of Benedict's qualitative solution is mixed with 0.5ml of urine and the mixture is put in a boiling water bath for 5 minutes. The results are recorded thus:\n\nno precipitate — \nGreen a trace \nyellow + \norange ++ \nred +++ \n\nOnce sugar is detected in urine, further tests have to be undergone in order to ascertain which sugar is present. Only glucose is indicative of diabetes.

sugar.. and sweet stuff.. mainly saccharides...

Distillation. Put sugar water in a crucible or beaker and heat over a burner. When all the water has evaporated, the sugar will be left. If you are actually going to carry out this experiment, be careful to not burn the sugar after the water has evaporated, unless you don't mind throwing out the beaker or doing some serious scrubbing.

To detect starch just add some drops of iodine to the substance you want to test. Iodine is yellow/brown and turns dark blue/black in the presence of starch. As for fat, just rub your substance if it is a solid on a piece of paper or place a drop of it on the paper if it is a liquid. If the substance leaves a translucent stain on the paper( stain that does not evaporate) then it has fat.

Refine Sugar? Zero.\n\nYou should try to get carbs from vegetables,grains and fruit

These are simple fast tests to detect the presence of carbohydrates in a given sample. These can be modified a little and by using a spec it would be possible to quantify the sugars in a given sample.\nQuestion if more precise would help in giving a specific answer

Please, ask your Dr. this question.  Do not take any risks with your health.  Your sugar could get really messed up with serious results.

You can work on fruit juices and other beverages like colas etc..carry out small analysis to find out how many of them contain glucose/sucrose ie aldoses and ketoses..u can also determine if they contain carboxylic acids,ascorbic acid etc.u can do benedicts/fehling test and lucas test on the different juices.can determine if any kind of OH group is present in those drinks..wt vitamins,wt minerals present.\nA similar kind of study can be done on toothpastes..take different brands of toothpastes,carry out tests on them as which ones contain Flouride,bleach,whitening powders and whiche all contains sugar.

1. Perform vacuum distillation.  Place the solution in a vacuum flask; apply vacuum (removing air from vessel); apply heat and "boil" the water off.  Collect the condensate and measure its volume.  Weigh the remaining sugar that is left behind in the vacuum flask.\n  -or -\n2. There may be a way to measure the refractive index of the sugar solution.\n-or-\n3. Heat a sample of the solution to determine the boiling point elevation; if you have a table that compares molarity vs. boiling point elevation, you may be able to determine the molarity of the solution by knowing at what temp. the solution boils.\n\n4. You may be able to extrapolate by weighing exactly one cubic centimeter (cc) (volume) of the solution at 25 degrees C.  There may be a table comparing weight of a 1 cc solution at that temp (as the density of 1 cc of water is different than a 1cc sugar solution.

Simple Suagrs can be tested with Benidicts Soultion which turnes from blue to yellow to orange to brown in the presense of a simple sugar when heated in a hot water bath.  Polysaccharides can be tested with iodine which turns purple in the presence of starchs.  There really is no simple test for disaccharides but they can be ruled out by testing for both simple sugars and polysaccharides.  Lipids are not carbohydrates but they can be tested for by a simple paper bag that becomes translucent when smeared with a lipid(like eating potato chips and touching a piece of paper) or with Sudan III which forms red rings on a piece of filter paper.

first of all, what type of diabetic are you? Type one or type two? (type one requires insulin)\n\nRegardless of that, you need to eat healthy. Don't be fooled by low or no sugar items because it is carbohydrates that really matter. Carbohydrates process into sugar. \nAnd, exercise, exercise, exercise. Exercise such as a 30 minute walk qill do wonders for you sugar level.\nLaslty, test your blood at least four times a day and record what time it was, what you ate and what the blood level was at. By doing so you will realise what effects certains foods have on your body.\nGood Luck!!

Lactose is a reducing sugar and will therefore react with Benedict's reagent. The reaction is quantitative, so you can measure the amount of copper(I) oxide formed. Of course this assumes that there are no other reducing sugars present, nor other material that might interfere. i assume that you are trying to measure lactose in milk or milk products. You would probably need to precipitate proteins first - by curdling with a little acid.

actually, a diabetes screen can be done from your urine.. what is described above is a Glucose tolerance test, where you have loads of sugar and see how your body deals with it... that is not a not a screening test. Either urine analysis or a finger prick to test glucose levels in blood.. just a pin prick...!
