Test: An experiment exposes the inside story of tonics.

original title: Test: An experiment reveals the inside story about tonics The market for fresh stewed bird's nests varies from price to price (there's actually a 30 yuan bottle of bird's nest), what's inside? At present, the raw materials of fresh stewed bird's nest are mainly: swallows, swallows, swallows and candor. But today Yandodo to do a small experiment with you, see if you bought bird's nest is the same?first to popularize a knowledge with you:
the food industry common thickener is agar
, agar is extracted from seaweed plant gum, often used in food thickener, coagulant, daily we eat jelly, yogurt will be added. Does adding agar thicken low-concentration fresh stew bird's nests? When the raw bird's nest ingredients are broken and swallowed, what does adding agar make it look like? Yandodo specially bought agar for everyone to do this experiment.. 1. Prepare experimental materials:We calculate the weight of the bird's nest according to a bottle of fresh stewed bird's nest 70 grams, bird's nest concentration of 20%, add trace amounts of agar (0.06%), dry bird's nest hair for 8 times.. 2. Bird's nest foaming:two groups of bird's nests to add 70 ml of pure water, foaming 4 hours 3. Bird's nest stewing:foaming finished. Place the tweeds in two stews, add water to the bird's nest, and add the agar to one bowl and simmer with water.. 4. The stew is finished with a comparison:the stew is finished, we put the bird's nest in the glass and see more clearly. As you can see,
only the nest snares of swallows
,
looks clear
.and
add agar to the bird's nest
more
turbid
, showing a vague appearance. Increase the amount of agar after actually cooling to achieve the effect of pouring bottles. In contrast
only a high concentration of bird's nest
with a stew ediphy
, the
solid stakes up to 90%

, the swallows are clear, and the swallows are swallows.we also tried to
agar
, is it very much like bird's nest? But it tastes different, the swallows are Q-bombs, and the agar is a little brittle.Low concentrations of fresh stewed bird's nests (concentrations below 25%) add trace amounts of agar (6 out of 10,000, or 0.06%), just to increase the density of water proportion and tension, so that the bird's nest solids do not sink phenomenon, the purpose is to maintain the shape of the product.
high concentration of fresh stewed bird's nest
does not need to be added, because the bird's nest content is more, the decomposition of the glue itself is enough to support the suspension of solids.we recommend that
eat 3 grams of bird's nest
a day, but how much of the bird's nest can be eaten with agar to add to the filling number? So many friends who buy poor quality fresh stewed bird's nests and ready-to-eat canned bird's nests complain that
ate a little effect.many powders, if you have time at home can also do this experiment according to many methods, see if you buy bird's nest is really bird's nest, after all, is something to eat, cautious or good, today with you to share here, pay attention to Yando do not lose, we see next issue!
