1. Buy at organic food stores or regular supermarkets and buy regular brands.
Market vendors' vegetables** are constantly changing and unstable. If you don't know much about organic vegetables, it is recommended to go to a reputable organic food store to buy them. In addition, large supermarkets are also a good choice, on the one hand, the reputation of large supermarkets is more guaranteed, the procurement process will be stricter, and sometimes supermarkets will be cheaper than organic food stores because of bulk purchases.
Choosing a strong regular brand is also an effective way to ensure food quality.
2. Pay attention to the organic certification mark on the packaging.
According to the relevant regulations of our country, the packaging of organic food must have two logos at the same time, one is the organic food logo, and the other is the organic certification logo.
3. Pay attention to whether the relevant information of the producer is clear on the packaging bag.
Regular organic vegetable manufacturers will paste the product traceability code and product-related information (producer unit name, address, **) on each vegetable, etc., which can be queried by relevant ** or relevant departments based on these information.
Fourth, look at the storage time.
Organic vegetables are more resistant to oxidation and can be stored longer because they are not chemically used. Generally, leafy vegetables can be stored for 3-4 days in refrigeration, and fruit vegetables can be stored for about 1 week. In addition, organic vegetables generally rot partially and the decay process is slow, and vegetables that have been used with chemical fertilizers are mostly rotten whole.
Fifth, use pesticide residue detection card.
At present, there are testing institutions on the market to develop a rapid pesticide residue detection card, through this test card to detect pesticide residues in vegetables is fast (about 15 minutes) and the cost is not high, if the pesticide residues exceed the standard, it is definitely not organic vegetables.
Sixth, by taste.
Not all organically grown vegetables have significant differences in taste from non-organic vegetables, but when carefully compared, there are still quite a few varieties that have significant differences, such as cucumbers, leeks, tomatoes, etc., especially cabbage.

RoundupDifference Between Organic Food and Inorganic FoodYes: Organic food is a green cycle in which silver ants feed their lives with life. Organic food does not contain any chemical ingredients that are pure and inanimate.
It is a natural nutrient cultivated by microorganisms or naturally converted into natural nutrients to nurture a variety of edible plants. There is no threat to human health.
Organic food is food with zero pollution, that is, food that is not contaminated by chemical fertilizers, pesticides, herbicides, etc., and the fertilizer must be composted naturally, and any additives that harm the soil cannot be used.
Features of organic food.
100% natural, organic food does not contain chemicals and pesticides, no additives, and needs to meet a number of national organic certification standards for the whole process of production, processing and sales. Organic food grows up in a pollution-free natural environment during the growth process, and the food does not contain any artificial, antibiotic, genetically modified substances and chemical pesticides and synthetic fertilizers, which is natural and pure.
Organic food is grown in accordance with the laws of biological nature, and the resulting food is rich in natural nutrients such as iron, minerals and vitamins. Organic food does not allow the addition of any additives that add to the taste, such as sugar, thickeners and flavors.
Organic agriculture adopts the "crop rotation method", on the one hand, using organic fertilizers, crop residues, animal and plant compost, to maintain soil productivity and provide plant nutrients; on the other hand, biological pest control methods are used to control pests, pests and weeds; To save energy, protect soil, air and water, practice sustainable agriculture, and protect the planet and the environment.

There are many reasons for choosing organic food, such as:
1. Safety. Organic food has very strict certification standards, and does not use any synthetic fertilizers, pesticides, herbicides, growth regulators, antibiotics and genetically modified ingredients in the production process.
2. Health. Organic cultivation makes the soil richer in nutrients, contains more trace elements such as iron, magnesium and calcium and vitamins than ordinary foods, and has lower levels of heavy metals and carcinogenic nitrates.
3. Delicious. Organic farming advocates maintaining the natural composition of the product, so that the food itself can be tasted naturally and delicious.
4. Environmental protection. The organic farming system protects and builds fertile land with high productivity. The quality of rivers, rivers, lakes, seas and drinking water has been improved.
Introduction: Organic food is a food with zero pollution, that is, it is not polluted by chemical fertilizers, pesticides, herbicides, etc., and the fertilizer must be composted naturally, and any additives that harm the soil cannot be used.

Nowadays, the standard of living is improving, eating not only to be full, but also to eat delicious and safe, but there are some unscrupulous businesses, for their own interests, the manufacture and production of food may be harmful to the human body, many people have heard of organic food, is a more reassuring food, so what is called organic food?
1. Main varieties
Organic food mainly includes general organic agricultural products (such as organic grains, organic fruits, organic vegetables, etc.), organic tea products, organic edible mushroom products, organic livestock and poultry products, organic aquatic products, organic bee products, organic milk powder, collected wild products and processed products with the above products as raw materials. The organic food sold in the domestic market is mainly vegetables, rice, tea, honey, goat milk powder, organic grains, organic fruits, organic vegetables, etc.
2. Judgment criteria
1. The raw materials come from the organic agricultural production system or wild natural products.
2. In the process of production and processing, organic food must strictly follow the standards of organic food production, collection, processing, packaging, storage and transportation.
3. In the process of organic food production and processing, a strict quality management system, production process control system and tracking system must be established, so a conversion period is generally required; This conversion process usually takes 2-3 years before it can be approved as organic.
4. Organic food must be recognized by a legal organic food certification agency.
3. Characteristics of organic food
1. Healthier studies have shown that organic products contain more trace elements such as iron, magnesium, calcium and vitamin C, while the content of heavy metals and carcinogenic nitrates is also low.
2. Organic agriculture advocates maintaining the natural ingredients of the product base, so it can maintain the original taste of food.
3. Avoid the outbreak of disease-intensive animal feeding methods such as avian influenza, which can easily spread diseases, while organic agriculture requires open animal feeding methods that allow animals to stretch their activities, enhance animal resistance, and reduce the chance of disease spread.
4. Contains less chemicals, under the concept of organic production, all production and processing processes are only allowed to apply chemicals under limited circumstances.
5. The production process does not contain genetically modified ingredients, and under the concept of organic production, no genetically modified organisms and their derivatives can be used in all production and processing processes.
6. It is beneficial to the environment and ecology to encourage, use natural materials, appropriate fertilization and irrigation, reduce resource waste, and improve biodiversity in and around the farm.
7. Protect the soil, soil degradation and pollution are becoming more and more serious, and soil as the basic element of food production, human beings must protect it.
Organic agroecology requires soil conservation measures that restore and maintain the vitality of the soil, so that the soil can continue to provide sufficient and high-quality food for human beings.
8. The scale of organic production is small, the investment in manpower is large, and the risk cost and transportation cost are relatively high, so the price of organic products is naturally more expensive.
Baby's diet is a problem that parents should pay attention to, a good diet is not only conducive to the growth and development of the baby, but also can improve the baby's immunity and disease resistance, so we have to provide the baby with the best diet, but many parents still do not understand some of the principles of the baby's diet, for example, the baby should add some complementary food when the baby reaches a certain age, many parents do not know what to do.
Organic chemistry in college is actually very simple, and it is easy to learn it well, but the premise is that you must first understand each reaction process and reaction mechanism, and you must find some books that are comparative, such as Wang Xiaolan's organic chemistry. Memorize each basis, and you'll pick it up very easily. Firmly grasp the structural characteristics of organic molecules, relevant knowledge should be explained in detail in the chapter of chemical bonds in general chemistry, only to grasp the structure is more conducive to the grasp of the reaction mechanism, the understanding and grasp of the reaction mechanism has become the top priority of learning organic chemistry in college, because the complexity of the reaction mechanism and its diversity make organic chemical reactions produce completely different results under different conditions.
