How do I make liquid glucose from powdered glucose
I recently decided to make something that required liquid glucose, 140g of it. No problem in general, but for some reason none of my usual suppliers had stock (even tried pharmacies). The closest I found was glucose powder.
Unfortunately, having no clue how to "re-hydrate" the powder to a liquid form, I experimented. :-)
I can safely say that 100g glucose powder was way to much as a substitute for 140g of liquid glucose (which I expected).
However, I was wondering if any of you had a convenient method of turning powdered glucose into the wonderfully thick and sticky liquid glucose, in case I ever find myself in that position.

Well, the answer is "it depends." This is pretty much the same as asking, "I have sugar, and I want sugar syrup. How much water do I add?" It depends on the concentration you're looking for. If you're looking for a 24% solution, it's 24 grams of glucose in 76 grams of water. A 30% solution is 30 grams of glucose in 70 grams of water, etc, etc.
Unless you have some chemical reason to avoid dextrin, you can just substitute corn syrup. The only reason they use glucose in Europe is because they don't have our superabundance of corn.

Quick Answer about "How do I make liquid glucose from powdered glucose"
The correct ratio of powdered glucose to water will be 70g glucose powder and 30g of water. Now when you mix together these two ingredients it will make a thick paste, but rest assured that it will melt into a liquid when it is heated.Can you make your own liquid glucose?

Answer 2
I had the same problem yesterday and asked a chemist friend and he told me that the solubility ratio of glucose powder to water to make liquid glucose is 91gm powder to 100ml water. I mixed the powder into the water and zapped it in the mw for about 2 mins and it was fine. Recipe worked a dream!
Answer 3
Glucose syrups contain 70-91% w/v solids, with at least 20% dextrose. If you're mixing glucose powder and water only, use 70g-91g glucose for every 30g (30mL) water, and heat the mixture in a double boiler (or carefully in a saucepan) until all sugar is completely dissolved.
It will be thick!
Take care not to heat the solution for too long or you will lose too much water to evaporation. If you know the weight of your top pot/saucepan you can weigh the glucose mixture in it while working to check how much water remains and whether you should consider replacing lost water.
Be sure to dry the bottom of your top pot before weighing if you do this, and be careful moving about pans containing hot liquids.
Keep in mind that any additives or alternative sugars count towards the solids weight fraction and may require more or less water to dissolve than glucose alone.
It's much easier to make a 75% glucose syrup than a 90% glucose syrup as you are less likely to have problems with poor supersaturation (dissolving of sugar) or re-crystallization during cooling if you use a lower concentration. It will work just fine in your recipe, either way.
Answer 4
I've a got a simple recipe for all of you. Just take 2 cups of sugar, 1/4 cup of water, 1/2 tsp. lemon juice, pinch of salt, 1/2 tsp. of baking soda. Add all of the ingredients to a sauce pan, cook for about 5 minutes and your glucose syrup is ready to use.
Answer 5
I tried making my own glucose syrup, as there were no speciality baking shops in my vicinity.
I did it mixing:
- 35 g (2.5 tbsp) of water with
- 2 tsp fine sugar
- 1 tsp cornflour
You can adjust the amount of water used, by using a little more or a little less of it.
