  Butyric acid , a four-carbon organic acid produced in the human body by the fermentation of probiotics. For the past ten years, my main research has been on this magical little molecule. The butyric acid mentioned here is n-butyric acid. Isobutyric acid, in the body, does not do anything. The easiest way to achieve gut health is to consume a high fiber diet containing lots of different plant foods. The reason for this is that fiber, especially prebiotic fiber, feeds our intestinal microbes. The fermentation process produces short-chain fatty acids, which are associated with beneficial health outcomes. In short, it is actually short-chain fatty acids that provide many of the benefits associated with gut health. Three main types of short-chain fatty acids exist: butyric acid, propionic acid and acetic acid.   Benefits of butyric acid     Butyrate benefits include reduced inflammation and risk of certain chronic diseases, including obesity, heart disease and type 2 diabetes, support for

Feed additives  are ingredients that are added to feed in small quantities and play certain important roles. For example, they can improve feed characteristics by providing nutritional value, texture, flavor, emulsification and preservation of the feed. Examples that most people will recognize are   vitamins , amino acids (components of protein), preservatives, and antioxidants.   For farm animals, the majority of their diet usually consists of corn, wheat and soybean meal. To avoid possible deficiencies and to ensure absorption of all essential nutrients, feed additives are required. These ingredients play a key role in ensuring proper animal nutrition and therefore the health and well-being of the animals.   However, feed additives offer many other benefits. In fact, among other things, they can reduce the environmental footprint of animal agriculture as well as support animal welfare and improve their resistance to infectious diseases.    L-(+)-Selenomethionine Feed additives are ve

Nitrifying bacteria   convert ammonia, the most reduced form of nitrogen in the soil, into nitrate, its most oxidized form. By itself, this is important for soil ecosystem function, controlling soil nitrogen loss through nitrate leaching and denitrification. Nitrifying agents also contribute to other important processes, including nitrous oxide production, methane oxidation, degradation of organic compounds, and carbon monoxide oxidation.   Nitrifying bacteria are traditionally considered to be exclusively aerobic; they require molecular oxygen for the reactions and respiration in the N oxidation pathway. However, they are considered to be microaerobic and they grow best under relatively low oxygen conditions. Microaerobiosis may be important in interfacial environments, such as the sediment-water interface and the oxygen minimum zone of the ocean.   While net nitrification and growth at the expense of inorganic N occurs only under aerobic conditions in autotrophic nitrificators, NH 3

   What is vanillin  used for ? Vanilla is one of the most popular flavors in the world. It comes from the fruit of the vanilla plant, which contains the beans or seeds from which vanilla extract is obtained.  Vanillin  is the main substance of vanilla bean extract and is responsible for the characteristic sweet taste of vanilla. Vanillin has a strong and distinctive vanilla bean flavor, with a stable aroma that does not volatilize easily at higher temperatures. It is susceptible to light, oxidizes gradually in air, and is easily discolored by alkali or alkaline substances. It is particularly widely used in confectionery, chocolate, beverages, ice cream and wine, and can also be used to flavor tobacco. It is also an important flavor enhancer for beverages and foods. It is also used in the manufacture of pharmaceutical levodopa, methyldopa, etc. It is also used as a brightening agent for nickel and chrome plating. Human exposure to vanillin is through skin contact with perfumes and inge

  What are the functions of activated carbon from coconut shell. 1.  Coconut shell  granular activated carbon  is often used in gas phase adsorption, and the air flow is usually adsorbed through the activated carbon layer. According to the different states of the activated carbon layer in the adsorption device, the adsorption layer can be divided into fixed layer, moving layer and flow layer. However, in small adsorbers such as refrigerators and deodorizers in cars, adsorption depends on the convection and diffusion of gases. In addition to granular activated carbon, activated carbon fibers and activated carbon products are also widely used in gas phase adsorption. 2. The air in instrument rooms, air conditioning rooms, basements and undersea facilities often contains body odor, smoking odor, cooking odor, oil, organic and inorganic sulfides, corrosive components, etc., due to external pollution or affected by the activities of people in a closed environment.

What is SF6 Gas？ Sulphur hexafluoride – also known as SF6 – is a ‘greenhouse gas’ that has long played a part in global warming, similar to that of carbon dioxide (CO2). What is SF6 greenhouse gas? SF6 is a synthetic, odourless gas that’s used in the electricity industry to keep networks running safely and reliably. It’s highly stable, non-toxic, non-flammable and electronegative, which means it will not form other compounds that will alter its state and effectiveness. SF6 has historically been used in a variety of applications, from metal smelting to filling double-glazing panels, but the electricity industry is one of the few places where it’s still used today; due to the technical challenges in replacing it. And it’s used on such a scale that it’s become a serious contributing factor to global warming.   Why is SF6 harmful to the atmosphere? SF6 is one of the most potent greenhouse gases we know. Its high atmospheric stability and ability to trap infrared radiation means it’s far mo

  Features of  Lithium Molecular Sieve 1.Lithium based molecular sieve is a synthetic zeolite of lithium-type crystal structure, large Nitrogen adsorption capacity, high efficiency of oxygen/nitrogen separation.Thus, gives a facility to use this system in future operations as well. 2.Lithium based molecular sieve shows high N2/O2 separation under a very low pressure, which lowers the consumption of producing oxygen. 3.The advantage of on the equilibrium adsorption capacity, and lithium molecular sieve is  applies to various VPSA device for  oxygen concentrator.

These portable devices use a pressure swing principle (PSA) to pass ambient air through a molecular sieve adsorbent, concentrating oxygen in the process. Portable oxygen concentrators allow for easy home-based patient car

Redispersible polymer powder   is a powder dispersion formed by spray drying of modified polymer EVA/VAE emulsion. It has good dispersibility. It can still be re-emulsified into a stable polymer emulsion after adding water. Its chemical properties are exactly the same as the initial lotion. Therefore, in order to make it possible to produce high-quality dry mixed mortar and improve the performance of mortar, today we will talk about the applications of Redispersed polymer powder. Redispersible polymer powder is an essential functional admixture for dry mix mortar, which can improve the high performance of mortar, the bonding strength of mortar and various substrates, the flexibility, tensile strength, compressive strength, bending strength, wear resistance, toughness, adhesion, water holding capacity and processability.     Masonry mortar and plaster RDP provides a mortar with good impermeability, high water retention and frost resistance and high bonding strength, which can solve the
