6. Food safety tips

1. What vegetables are easy to cause poisoning in our daily life?

1. Vegetables contaminated with pesticides. In order to grow vegetables quickly and well, vegetable farmers spray vegetables with high-concentration pesticides and put them on the market early.

2. Uncooked green beans and kidney beans contain saponin and trypsin inhibitor, which will cause poisoning to human body.

3. Both germinated potatoes and cyan tomatoes contain solanine toxic substances, which will cause dizziness, vomiting, salivation and other poisoning symptoms after eating.

The bean sprouts planted with chemical fertilizers are all ammonia-containing compounds, which can be transformed into a carcinogen called nitrosamine under the action of bacteria. Long-term intake will cause gastric cancer, esophageal cancer, liver cancer and other diseases.

5. Fresh day lily (also called day lily) contains colchicine. Acute gastroenteritis will occur when a large number of fresh day lily is eaten without water boiling or incomplete heating.

6. Broad beans. Some people will get hemolytic jaundice and anemia after eating broad beans, which is called bean disease (also called bean yellow).

7. Fresh fungus. It contains a porphyrin photosensitive substance, which is sensitive to light and can cause solar dermatitis after being irradiated by the sun.

In addition, we should pay attention to the purchase, storage and preservation of vegetables. Before eating vegetables, you must "wash once, soak twice, scald three times and fry four times" to ensure safety.

Second, the shelf life of overnight dishes

Overnight vegetables have been stored for some time because of pollution during eating. Vegetables are high in microbial content, and there are indeed health problems. Improper diet will affect health. So, what are the tips for overnight food processing?

If there is food left, put it in the refrigerator as soon as possible after eating, which can shorten the storage time at room temperature and slow down the growth and reproduction of bacteria in vegetables. Secondly, it must be heated before the next meal, because some pathogenic bacteria can not cause food deterioration, but can make people sick. If food is heated, most microorganisms in food can be killed.

Shelf life of overnight vegetables: 1, and overnight vegetables can be kept at a low temperature below 5 degrees for 1-2 days. If stored for more than 3 days, naturally occurring nitrate in vegetables will be converted into nitrite, which is carcinogenic and cannot be removed by heating. 2, animal food in 25-30 degrees, 3-4 hours will be bad. 3. Cold salad, jellyfish and other cold salad were polluted during processing. Even if it is refrigerated, it is likely to have deteriorated after a night, and it should be eaten now. 4. The salted food contains a lot of salt, and the safe eating period can be extended to 3-4 days.

Third, how to reduce pesticide residues in vegetables.

1. Soaking method: The pesticides contaminated on vegetables are mainly organophosphorus pesticides. Generally, wash off the dirt on the surface with water first, and then soak it in clear water for 30 minutes. Repeated washing and soaking for 2 to 3 times can basically remove most of the residual pesticides.

2. Alkaline water soaking method: The method is to rinse the dirt on the surface first, soak it in alkaline water (usually 500 ml of water and 5- 10g of alkaline noodles) for 5- 15 minutes, then rinse it with clean water, and repeat it for 3-5 times.

3. Storage method: The pesticide residues on vegetables can be slowly decomposed over time. Non-perishable vegetables such as wax gourd and pumpkin can be put 1 week before eating.

4. Hot water method: Some vegetables and fruits can remove some residual pesticides by hot water. Commonly used in celery, spinach, green pepper, cauliflower, beans and so on. Clean the dirt on the surface with clear water, put it in boiling water for 2-5 minutes, and then rinse it with clear water 1-2 times.

Four, the shelf life and shelf life of food

Pay attention when buying food: the shelf life or preservation period of food is a period of time, counting from the date of production. The production date refers to the standard date when all food production (processing) processes (procedures) are completed and reach the sales.

When buying food, we will find that besides the food name, ingredients, manufacturers, operators and other items, there is also a very important content on the packaging or label of food, that is, the shelf life or storage period of food. In order to enhance the awareness of health and hygiene self-protection, we should understand the meaning of shelf life or food shelf life.

Shelf life is the best edible period of food, and shelf life is the recommended final edible period. If the shelf life or storage period is related to the storage conditions of food, the storage method must be indicated, such as cold storage, dark storage, storage in a cool and dry place, etc. Consumers should also pay attention to whether the seller's sales environment meets the requirements on the label when buying food.

7. Life knowledge about food safety

First, what is food quality and safety?

Food quality and safety refers to the degree to which food quality ensures the health and safety of consumers. Include three aspects:

First, the quality and safety problems caused by food pollution. For example: biological pollution, chemical pollution, physical contamination, etc.

The second is the quality and safety problems brought about by the technological development of the food industry. Such as: food additives, food producers, media, radiation food, genetically modified food, etc.

The third is the abuse of food labels. Examples: forged food labels, lack of warning instructions, false labeling of food functions or ingredients, and lack of Chinese food labels (imported food).

Second, what is the food quality and safety market access system?

The market access system of food quality and safety refers to the administrative supervision system that allows producers who meet the prescribed conditions to carry out production and business activities and products that meet the prescribed conditions to produce and sell in order to ensure food quality and safety. It is an administrative licensing system. The principle of system establishment is the combination of pre-guarantee and post-supervision and the combination of * * * supervision and enterprise self-discipline to give full play to the role of market mechanism. It mainly includes three basic contents:

1. review system of necessary conditions for food production enterprises: enterprises that process and sell food in China must have the necessary conditions to ensure product quality and obtain food production licenses according to the prescribed procedures before producing food;

2. The formulation of compulsory inspection: food production enterprises must fulfill their legal obligations, and the products can only be sold after passing the inspection;

3. Food quality and safety mark system: The food sold after inspection must be printed with (affixed with) the food quality and safety market access mark, that is, the "QS" mark.

3. What foods must be marked with QS mark at present?

The first five categories of food that must be marked with QS are wheat flour, rice, edible vegetable oil, soy sauce and vinegar.

The second batch of food that must be marked with QS mark is classified as 10, mainly including meat products, dairy products, beverages, condiments (sugar and monosodium glutamate), instant noodles, biscuits, canned food, frozen drinks, puffed food and quick-frozen rice and flour products.

The third batch of food that must be marked with QS is classified as 13, mainly including candy products, tea, wine and fruit wine, beer, rice wine, pickles, candied fruit, roasted seeds and nuts, egg products, cocoa products, coffee, aquatic products, starch and starch products.

Fourth, how to distinguish fake and shoddy food?

Fakes are like rats crossing the street, and everyone cries out. But it's hard for people to recognize it in their daily shopping. The "Seven-character Law on the Prevention of Fake and Inferior Foods" guides consumers to strengthen food safety self-prevention in an easy-to-understand and easy-to-remember way, so that fake and inferior foods will withdraw from the market due to lack of market. Beware of the "seven-character method": that is, beware of "bright, white, reverse, long, scattered, low and small".

Beware of "colorful". Beware of foods with too bright colors. For example, strawberries on the market are as big, red and bright as wax fruit, pickles are bright yellow and attractive, and bottled bracken is bright green and does not fade. Be careful. Is there a problem with adding pigment?

Second, beware of "white". All foods are abnormal and unnatural white, and nine times out of ten there will be hazards of chemicals such as bleaching agent, whitening agent and flour treatment agent.

Three defenses "long". Try to eat less food with long shelf life. Packaged cooked meat and poultry products stored at 3℃ are pasteurized, and the shelf life is usually 7-30 days.

Four defenses "counterattack". It is food that prevents unnatural growth. Eating too much may have an effect on your health.

Five precautions against "small". Beware of the products of small workshop-style processing enterprises, which have the lowest average pass rate in food sampling, and shocking food safety incidents often appear in these enterprises.

Six defenses against "low". "Low" refers to the food whose price is obviously lower than the general price level, and most of the food whose price is too low is "tricky".

Seven prevention "scattered". Bulk is bulk food, and some bulk bean products, cooked food and pickles sold in the market may come from underground processing plants.
