How to Make Special Purchases for the Spring Festival?
The Chinese New Year is coming, and many people are taking advantage of these days before the Spring Festival to make special purchases for the family. How should we choose in the face of all kinds of goods? And how to get rid of food safety risks?
Roasted Seeds and Nuts
Roasted seeds and nuts have high nutrient value. However, due to their high fat content, especially the content of unsaturated fatty acid, it's easy to be over-oxidized during the storage of ingredients and finished products, which manifests that the peroxide value and the acid value exceed the standards and the products become rancid.
Tips for purchasing roasted seeds and nuts:
· It is better to choose roasted seeds and nuts in vacuum packing, nitrogen-filled packing and light-proof and oxygen-isolated packing, which is beneficial to delay rancidity.
· When buying more roasted seeds and nuts, try to store them in sealed bags and keep them away from light and high temperatures.
· Select the products with appropriate net contents. And it is best to eat them up in a short period after opening.
· After the product is opened, if there is a rancid smell or a bad taste, or the color of the surface had changed, it can no longer be eaten.
Drinks
Pay attention to product labels when purchasing drinks. Don't buy or drink products without labels or with incomplete label information, unclear label contents and beyond the shelf life.
Once the carbonated beverages are opened, carbon dioxide will escape and affect the taste of the drinks. Hence, consumers are supposed to select different specifications of products according to their needs. And carbonated drinks can't be frozen. This is because the solubility of carbon dioxide of drinks in water will decrease after freezing, which leads to the precipitation of a large amount of gas from water and the excessive pressure in the bottle that may deform and explore.
Lactobacillus drinks can be divided into inactive (sterilized) type and active (unsterilized) type according to whether they are pasteurized or not. Inactive lactobacillus drinks can be preserved at room temperature. On the contrary, the storage and transportation of active lactobacillus drinks must be under the condition of 2-8℃, otherwise the viable count of lactobacillus would decline and the taste of drinks would be affected. When buying and storing drinks, it's easy to distinguish between them by labels and marks.
Juices should be preserved under suitable conditions according to their label instructions. They need to be stored in the refrigerator at 0-5℃ after being opened, and finished within 48 hours. And the fresh juices pasteurized or sterilized by ultra-high pressure should be refrigerated at low temperature. With a relatively short storage time, they ought to be drunk as soon as possible to avoid the growth and breed of microbes.
Cured Meats
When purchasing cured meats, we can distinguish them by the appearance, color and smell of the goods. First, the color should be normal and without mildew spots and mucus. Second, there is no unpleasant or rancid odor. Third, the texture of the meat is clear, and there is no visible foreign matter. Cured meats need to be stored in a cool and dry place at room temperature. And in summer with high temperatures, it is recommended to preserve them in the refrigerator.
In addition, it's better to stir-fry cured meats with vegetables that are high in dietary fibers and vitamins, like cabbage, broccoli and green beans, to achieve salt reduction and keep a balanced diet.
