According to function: organic acid powder can be divided into flavoring agents, preservatives, acidifiers, nutritional fortifiers, and other types. Common organic acid powders are kojic acid powder, glycyrrhizin powder, and so on. Kojic acid powder is a kind of weakly acidic organic compound made by microorganisms through fermentation, which is mostly used in food, cosmetics, and other fields. Glycyrrhizin powder is a brown powdered organic synthesis intermediate, which is often used in medicine food, and other industries. Organic acids powder mainly has the following effects: Organic Acids Powder,Acid Citric Sweetening,Citric Acid Monohydrate,Malic Acid Food Additive,Saffron Extract Shaanxi Changsheng Industrial Co., Ltd. , https://www.cncsbio.com
According to the source: Organic acid powder can come from natural plants, animals, or microorganisms, and can also be obtained by chemical synthesis.
According to the structure: organic acid powder can be divided into carboxylic acid, ester, amide, and other types.
1. Antibacterial anticorrosion: can inhibit the growth of microorganisms, and extend the shelf life of products.
2. Seasoning and acid: adjust the acidity of food, and improve taste.
3. Promote digestion: help the secretion of digestive fluid, and promote the digestion and absorption of food.
4. Antioxidant: Has a certain antioxidant capacity, and can protect food and human cells from oxidative damage.
5. Nutritional enhancement: Some organic acid powder also has a certain nutritional function.
Fruit tree autumn tube misunderstanding
Autumn is a crucial time for fruit tree care, yet many growers mistakenly believe that heavy pruning should be avoided after harvest. In reality, this is a misunderstanding. During autumn, the favorable light and temperature conditions support efficient photosynthesis. By employing techniques such as shortening branches, thinning, retracting, bending, and "opening the skylight," you can improve air circulation and light penetration, which are essential for flower bud development and nutrient accumulation.
It's also important to apply base fertilizer promptly after harvesting early varieties, rather than following traditional practices. These fertilizers typically include high-quality organic materials like compost, manure, and crop straw mixed with compound fertilizers. After application, deep tilling and timely watering help maximize fertilizer efficiency. At this stage, the soil moisture and temperature are ideal for promoting new root growth, healing wounds, and improving nutrient and water absorption. Missing this window means wasting valuable resources like sunlight, heat, water, and nutrients.
Many orchard owners fear that root health is compromised by normal growth, but the key lies in ensuring a healthy root environment—loose, well-ventilated soil with balanced moisture and nutrients. Unfortunately, in many orchards, soil compaction has become a serious issue, leading to poor root function and stunted tree growth. In areas with heavy clay soils, excessive use of chemical fertilizers without organic amendments worsens compaction. Some farmers even avoid loosening the soil, fearing damage, which only leads to more hardened ground over time.
After fruit harvest, some people think there's no need for spraying. However, this is not the case. Autumn is an important period for disease and pest prevention. The tree enters a natural resting phase, often referred to as "breaking the tree." During this time, spraying helps protect leaves, extend their functional life, enhance photosynthesis, and boost nutrient storage. It also reduces the risk of overwintering pests and diseases. Key targets include pear black spot, apple brown spot, leaf roller moths, and webworms.
Lastly, many neglect proper branch training and angle adjustment. Throughout the growing season, as fruits develop and the tree load increases, adjusting the angles of main and side branches improves ventilation and light exposure. From fruit ripening to harvest, the tree reaches its optimal angle. After harvest, the tree maintains a stable angle for a while. If the angle cannot be maintained naturally, techniques like tying, bracing, or using supports can help fix the position and ensure long-term structural stability.
The classification of organic acid powder can be divided according to its source, structure-function, etc. Such as Acid Citric Sweetening, Citric Acid Monohydrate, Malic Acid Food Additive, and Saffron Extract. The following are some common classification methods:
