Hot and sour powder is made of pure sweet potato powder. Sweet potato is a rhizome plant, which contains high starch, cellulose, potassium and vitamins A and C. It can prevent hypertension, maintain eyesight and improve constipation. Adding hot and sour powder helps to prevent colorectal cancer.

Lactic acid in sauerkraut in hot and sour powder can stimulate appetite, refresh the mind, sober up and relieve boredom, promote appetite, help digestion and promote the absorption of iron by human body. At the same time, the Chinese cabbage turns sour, and the nutrients contained in the hot and sour powder are not easy to lose.

However, sauerkraut can only be eaten occasionally. If the human body lacks vitamin C, it should eat less, which is not suitable for long-term overeating.

In addition, the hot and sour powder is also rich in carbohydrates, dietary fiber, protein, nicotinic acid and minerals such as calcium, magnesium, iron, potassium, phosphorus and sodium. Vermicelli has a good flavor, it can absorb the taste of all kinds of delicious soup, and the vermicelli itself is soft and smooth, making it more refreshing and pleasant.

Disadvantages of eating hot and sour powder:

Traditional vermicelli should be fumigated with alum, sulfur and sodium bicarbonate. Alum, whose scientific name is potassium aluminum sulfate, releases a large amount of aluminum ions easily absorbed by human body in aqueous solution. Excessive intake of aluminum can directly destroy the genetic material of nerve cells and the function of deoxyribonucleic acid, and make brain cells degenerate.

1, can invade fetal brain through placenta, make it form brain lesions, and increase the incidence of dementia in children.

2. Invade the human brain, causing memory loss, mental decline and slow response.

3. Aluminum ion deposition in bones can lead to osteoporosis, fracture and joint pain.

4. Aluminum ions deposited on the skin will reduce skin elasticity and increase wrinkles.

5, the elderly have weak digestive ability, and long-term consumption of food containing alum is more likely to increase the accumulation of aluminum in the body, leading to the occurrence of Alzheimer's disease.

Because spicy and pepper are poisonous, overeating will make the body hot and humid, which is manifested as acne on the skin, increased blood pressure, aggravated hemorrhoids, nosebleeds and so on. If you eat pepper in large quantities for a long time, it will cause poisoning symptoms, such as burning sensation in the stomach, bloating, abdominal pain, nausea, vomiting, dizziness, and even vomiting blood, hematuria, nosebleeds, and increased or decreased blood pressure.

Animal experiments have confirmed that capsaicin, the main component of pepper, has certain influence on the circulatory system, which can cause transient blood pressure drop, slow heartbeat and dyspnea. So eat too much pepper and be careful of poisoning.

Taste types and tastes

In the production of hot and sour powder, the seasoning techniques of Chongqing noodles are used for reference, such as using pepper and sea pepper to obtain the basic orientation of flavor. But the inherent physical characteristic of sweet potato vermicelli is that it does not smoke spices. In this regard, Chongqing people who are obsessed with taste and like to study have created sweet potato vermicelli with unique taste rooted in Chongqing characteristics but with distinct personality.

Because vermicelli should not absorb moisture and flavor, the flavor of hot and sour powder is heavier than that of ordinary local soup powder. For example, ginger and garlic powder is not added to soup, but directly added, which makes the use of spicy taste more violent and choking.

More importantly, the use of vinegar is a pioneering work. Volatile vinegar can stimulate the smell of other spices to form a comprehensive aroma, so that a bowl of hot and sour powder can be smelled far away. Authentic Chongqing hot and sour powder does not use Shanxi vinegar or balsamic vinegar. Baoning vinegar, which has a history of hundreds of years, is brewed with water in the middle reaches of Jialing River in winter. It is fragrant in acid and slightly sweet, and the smell of acetic acid is subtle but not pungent. It is the authentic collocation of Chongqing hot and sour powder.
