Selection and purchase method of Sweet Potato starch

1. Visual observation: the color of sweet potato starch is fresh and white, indicating that there are fewer impurities and the higher the whiteness, the better the quality. On the contrary, there are many impurities and poor quality. When judging, spread out 5 grams of sweet potato starch on a clean glass plate, crush the starch with another thick glass, and scrape the sample into a thin layer to see whether the color of sweet potato starch is white, glossy, and the number of spot inclusions. When watching, put the sample on the colorless transparent clean glass plate, lined with white paper to avoid direct light, using reflected light, colored impurities such as dust, plant leaf shavings, black sand and gravel can be clearly identified.

2. Finger twist: the approximate moisture content of sweet potato starch can be detected by finger senses. The method is to squeeze sweet potato starch vigorously with fingers, which can be twisted into thin slices. Shake off the thin slices on the fingers at a height of 20 cm from the table. If it is dry in the form of loose powder, the water content is less than 15%. If it is in the form of small fragments, the water content is 15-20%. If the sheet is basically not loose, the water content is more than 20%. Hold half a handful of sweet potato starch with your hand and hold it tightly with your hand. If you loosen your hand, the sweet potato starch will be relatively dry. If you hold it into a ball, it will be difficult to loosen your hand, indicating that the sweet potato starch contains too much water.

3. Listen: knead the sweet potato starch in the bag by hand, if you hear the sound of "click", or directly squeeze the sweet potato starch with your fingers, the sound of "click" is pure sweet potato starch. If the sweet potato starch is mixed with talc, wheat flour and corn flour, the sound will not be heard or not loud.

4, taste: take a small amount of starch into the mouth, according to the taste buds, teeth and other senses to distinguish whether the sweet potato starch has peculiar smell and impurities. For example, the sour taste is strong, which shows that the sweet potato starch is fermented too much when the acid pulp process is used, and the starch is not washed with clean water after precipitation. If the sweet potato starch has a sour mildew taste, it means that the sweet potato starch is stored for a long time when the humidity is high before drying, and the sweet potato starch is easy to break when it is processed. If there is talcum powder flavor, wheat noodle flavor, etc., it shows that these substances are mixed. When chewing with teeth, if you feel toothache, it means that there is more sand in sweet potato starch.

5. Water sinking: take 50 grams of sweet potato starch, put it in a beaker or white bowl, add water 150 to 200 milliliters and stir well, then stir 1 minute in one direction, stand still for 5 minutes, slowly pour out sweet potato starch milk, pay attention to the bottom layer of sediment or how much sediment. The sweet potato starch milk was precipitated in a colorless transparent glass or beaker for 3 hours to check the precipitation. If the precipitation is fast, the starch sinks neatly, the upper layer is green, and the bottom layer has no fine sand, it is high quality sweet potato starch. If the precipitation is slow, the upper water is more yellow and has more sand, which is a low-quality powder. If mixed with corn flour, rice flour, etc., it is not easy to sink in the water, and the upper water is extremely muddy.

7. Sample comparison: put different kinds of starch determined by inspection into colorless glass seed bottles or long colorless glass bottles, label them respectively, and indicate the grade, time and source of the samples. When evaluating sweet potato starch from different sources and different processing batches, it can be compared with the standard sample. In order to classify and use different grades of starch, in order to ensure the continuous stability of the quality of reprocessed sweet potato starch.

5. Pile tip: stack the sweet potato starch into a cone by hand to see the blunt roundness of the cone tip. The pile tip of pure sweet potato starch is low and slow, while that of adulterated sweet potato starch is high and steep.
