Winter Garden Trees Conservation

Winter tree care plays a crucial role in maintaining the ornamental and economic value of garden trees in the following year. Proper winter maintenance ensures that trees remain healthy, strong, and ready for spring growth. Here are key aspects to consider when caring for garden trees during the colder months: First, it's important to provide adequate water before the ground freezes. Even though evaporation is minimal in winter, trees still require moisture to survive the cold and support their growth in the coming season. In early November, especially for newly planted trees, a deep watering known as "frozen water" should be given. This involves watering thoroughly and then mounding soil around the base of the tree. This practice helps retain moisture, improves cold resistance, and supports the tree’s overall health. Second, fertilization is essential during late autumn and winter. As the above-ground parts of the tree slow down, the root system becomes more active. Applying organic or chemical fertilizers at this time can boost root development and enhance the tree's vitality. It's best to tailor the type and amount of fertilizer based on the tree's age and how long it has been planted. This will help ensure a strong start in the next growing season. Third, pruning is an important task that should be done before or after the winter solstice. Pruning helps shape the tree, improve air circulation, and promote better flowering and fruiting. It also removes dead, diseased, or weak branches, which can prevent the spread of pests and diseases. For larger cuts, it's advisable to disinfect them with a suitable solution and apply a protective coating like tree paint to prevent infection. Fourth, trunk whitewashing is a common practice in winter. The white paint helps protect the bark from temperature fluctuations and sunscald, especially on the sunny side of the tree. It also helps eliminate pests that may be hiding in the bark cracks. A typical whitewash mixture includes 10 parts of quicklime, 1 part salt, 1 part sulfur powder, and 40 parts water. This treatment is usually applied in November to prepare trees for the cold season. Fifth, removing dead or dying trees is necessary to maintain the aesthetic appeal of the landscape. Trees that have been damaged by disease, aging, or human activity can negatively impact the overall look of the garden. These trees should be removed promptly, and replacements should be planted to keep the area looking neat and well-maintained. Lastly, cleaning up weeds and fallen leaves is an important step in preventing pest and disease infestations. Weeds and leaf litter can serve as breeding grounds for insects and pathogens, and they also pose a fire hazard during dry, windy winters. Removing these materials and disposing of them properly helps reduce risks and keeps the garden clean and safe. By following these winter care practices, gardeners can ensure that their trees remain healthy, resilient, and ready to thrive in the next growing season.

Food Additive

What is Food additive?

Food additives refer to chemical synthetic substances or natural substances intentionally added to food in order to improve the quality, color, aroma, and taste of food, as well as for the needs of anti-corrosion and processing technology. These additives are usually added in small amounts during the food production process to enhance the sensory properties, stability, safety or convenience of the food.
The functional classification of food additives includes but is not limited to the following:
1. Acidity regulator: used to maintain the acid-base balance of food.
2. Anti-caking agent: prevent food ingredients from clumping or aggregating.
3. Defoamer: Reduce or eliminate foam in the food production process.
4. Antioxidants: prevent food oxidation and deterioration, extend shelf life.
5. Bleach: used to improve the color of food.
6. Leavening agent: make the food expand during cooking or baking.
7. Base agent substances in gum-based candies: ingredients that provide a gelatinous texture.
8. Colorants: give food a specific color.
9. Color protectants: Protect food color from oxidation or other factors.
10. Emulsifier: help oil and water and other insoluble substances mix evenly.
11. Enzyme preparations: used to catalyze specific reactions in food processing.
12. Flavor enhancer: enhances or improves the taste of food.
13. Flour treatment agent: Improve the processing performance of flour.
14. Film agent: Form a protective film on the surface of the food to prevent drying or oxidation.
15. Moisture retention agent: to maintain the moisture content of food, affecting its taste and shelf life.
16. Nutritional fortifier: Increase the nutritional value of food, such as adding vitamins or minerals.
17. Preservatives: prevent food from spoilage and extend shelf life.
18. Stabilizers and coagulants: improve the stability of food or make it solidify.
19. Sweeteners: Provide sweet taste and can be natural or artificial.
20. Thickener: increase the viscosity or thickness of food.
21. Edible flavors: Provide or enhance the aroma of food.
22. Processing AIDS for the food industry: substances that play an auxiliary role in the food processing process.
The definition and regulation of food additives may vary from country to country, but in general, their use must comply with relevant food safety regulations and standards to ensure that the specified amount of use will not cause adverse effects on the health of consumers. The Joint Food Regulatory Committee of the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) has also defined and classified food additives.
