Natural food coloring refers to pigments extracted or prepared from plants, animals, microorganisms or other natural sources for coloring food. These pigments are naturally produced due to biochemical reactions in living organisms and do not contain synthetic chemical components.

what is natural food color?
Natural food colors can be divided into the following categories according to their source:
1. Plant pigments: This is the most common source of natural food pigments, including pigments derived from a variety of fruits, vegetables, flowers, and plant roots. For example, red beets can provide red pigments, carrots can provide orange pigments, turmeric can provide yellow pigments, and blueberries and purple potatoes can provide purple and blue pigments.
2. Animal pigments: These pigments are rare and usually come from the tissues or excretions of certain animals. For example, cochineal is a red pigment derived from the cochineal insects that live on certain cacti.
3. Microbial pigments: Some microorganisms, such as monascus, can produce specific pigments, such as monascus red pigments.
4. Mineral pigments: Although less used, certain inorganic minerals can also be used as natural food pigments, such as titanium dioxide (white) and iron oxide (red, yellow and black). However, due to possible toxicity issues with some mineral pigments, their use is often severely restricted or banned.
Natural food colors are generally considered safer and healthier than synthetic colors due to their nature. However, their color stability, heat resistance, light resistance, and interaction with other food ingredients may not be as good as synthetic pigments, so their application in the food industry sometimes presents some challenges. At the same time, the extraction and processing of natural pigments can also affect their cost and sustainability. Nevertheless, as consumer concerns about food safety and health increase, the demand for natural food coloring is growing.
After the Spring Festival, it's time for spring flowers to bloom. Spring is a critical season for farmers, as they are busy preparing their fields and applying fertilizers to ensure healthy crop growth. In this article, we will discuss how to apply fertilizer correctly, focusing on both organic and microbial fertilizers.
Fertilization serves two main purposes: first, to increase the nutrient content in the soil so that crops can absorb and utilize them effectively; second, to improve soil structure, making it easier for plants to access nutrients. Whether using organic or inorganic fertilizers, both can be effective, but they work differently.
Inorganic fertilizers dissolve quickly and are immediately available to plants, which is why many farmers prefer them for quick results. However, organic fertilizers take longer to break down, as most of their nutrients are released gradually through microbial activity. This slower release makes organic fertilizers ideal for long-term soil improvement. With recent advancements in agricultural science and policy support, the composting process of organic fertilizers has become faster and more efficient. One such product is the Golden Treasure Organic Fertilizer Starter from Beijing Huaxia Kang, which enhances the quality and effectiveness of organic fertilizers.
In addition to improving nutrient availability, organic fertilizers also enhance soil structure. As they decompose, they release carbon dioxide and various acids that help dissolve insoluble minerals, increasing the availability of essential nutrients. They also promote the formation of stable soil aggregates, improving water retention and aeration. The humus formed during decomposition helps bind soil particles together, making clay soils less compact and sandy soils more fertile.
Microbial fertilizers, produced by specialized companies, contain beneficial microorganisms that further boost soil fertility. These microbes not only increase mineral nutrients and humus but also produce vitamins, antibiotics, and plant growth regulators like auxins. For example, Gymboron fertilizer improves soil nutrient availability by dissolving fixed nutrients and promoting the release of trace elements. It also helps reduce soil compaction and improve soil structure.
These microbial products stimulate plant growth by enhancing hormone production and increasing resistance to diseases and environmental stress. They have been shown to reduce the occurrence of common crop diseases such as rice blast, wheat powdery mildew, and bacterial wilt. Additionally, they improve drought, cold, and salt tolerance, leading to healthier crops and higher yields.
Using organic fertilizers alongside microbial fertilizers provides a balanced approach to soil management. This combination not only increases soil fertility but also promotes healthier crop growth, resulting in better-quality agricultural products. By adopting these modern techniques, farmers can achieve sustainable and productive farming while protecting the environment.
