People living in modern society are really extremely happy.
All kinds of trans-regional and trans-seasonal ingredients
Let our dining table enrich day by day.
But with it.
It is the fear and fear of food safety.
People used to throw away plates with bug eyes.
Now it seems that only such dishes can make people feel more at ease.
Although the dining table is small, its safety is very important.
Today, Shizijun teaches you several ways to choose safe and healthy ingredients.
Vegetables and fruits
The pollution degree of vegetables and fruits is higher than that of grain and beans, including pesticides, fungicides and herbicides, and they are also easily affected by environmental pollutants, especially industrial wastewater. The problem of excessive heavy metals such as lead, mercury and cadmium deserves attention. Excessive application of nitrogen fertilizer will lead to excessive nitrate in vegetables. Nitrate may be converted into nitrite after vegetables are stored and taste bad, which is harmful to health.
Vegetables are closely related to every family and everyone's daily life. Therefore, it is necessary to understand the safety of controlled vegetables from the source. Take some time to know whether the soil in the vegetable production base is polluted by heavy metals, whether the water source for irrigating vegetables is clean, whether pesticides, fertilizers and herbicides have been used in the whole production process, and ensure the freshness of vegetables.
In the selection of vegetables and fruits, in addition to understanding the excellent soil quality and clean water source in the vegetable production base, the use of genetically modified seeds, pesticides, fertilizers and herbicides can be given priority in the whole planting process. Also pay attention to giving priority to local and seasonal vegetables, because vegetables and fruits stored for a long time need to be treated with some chemical preservatives.
staple
Generally speaking, the ability of grain and bean seeds to accumulate pollution is low, but it is inevitably affected by environmental factors, especially heavy metal elements such as lead, cadmium and mercury, as well as agricultural chemicals such as herbicides, growth regulators and fungicides.
Therefore, when buying staple foods such as rice, flour and beans, you can understand the whole production process and choose a base with good planting environment quality, so you can basically rest assured of its safety.
Milk and eggs
The pollution problems of milk include refractory environmental pollution, all kinds of pesticide pollution from feed and veterinary drug pollution (such as antibiotics and hormones).
The pollution problem of eggs is similar to that of milk, but the antibiotic problem of milk is more prominent. The worse the feeding conditions of animals are, the more likely it is to have various infectious diseases, and the risk of veterinary drug residues will increase, and most of the drugs used by animals are toxic to human beings.
Therefore, the breeding base is selected in a place with high terrain, dry and good drainage. The eggs of native chickens scattered in the mountains can be first selected with insects and grass, supplemented by whole grains. High-quality yogurt is the safest dairy product because lactic acid bacteria are sensitive to pollution and antibiotic residues. If yogurt can be made successfully, it usually means that the quality of milk source is more reliable.
What exactly should I do?
Today, with frequent food safety incidents, more and more people have to give up the delicious food in restaurants and the convenient semi-finished products in supermarkets and choose to buy food and cook by themselves. So how can we practice "discerning pearls" and buy back safe and healthy natural ingredients?
When buying food, you should choose the one with QS mark, which is the sign that the enterprise obtains the production license.
When choosing food, you should carefully check the food packaging. Observe whether the packaging is damaged or leaked, and whether the font printing is regular, so as to avoid buying contaminated or counterfeit food.
Use the senses to preliminarily identify, smell and judge whether the food has deteriorated or emits abnormal smell.
Pay attention to the instructions and labels on food packaging. Among them, the following points need consumers' attention:
It is necessary to see clearly the production date and shelf life marked on the food packaging to ensure that the food is within the shelf life.
Food names must use the names specified in national standards and industry standards; Consumers should also pay attention not to be confused by some "new names", "novel names" or "brand names" used by enterprises, and pay attention to the names of real attributes of food.
Consumers should also pay attention to the situation of food additives in food. If food additives are used, they must be indicated on the label.
When buying food, you should go to a regular supermarket, shopping mall or shop to ensure the quality and safety of the food you buy.
