Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.

In theater, the tableau takes on an entirely different dimension. It serves as a staging technique where actors create a living picture, freezing in dynamic poses to convey emotions and pivotal moments in the narrative. This technique has been particularly prominent in classical theater, where a single scene can encapsulate the essence of a play. The tableau vivant, or living picture, engages the audience's imagination, compelling them to derive meaning from the stillness and the relationships portrayed among the characters. This method not only enhances the visual experience of the performance but also deepens the audience's emotional engagement with the story.

  • 2. Disinfectants To ensure microbial safety, disinfectants such as chlorine, chloramine, and ozone are commonly used. Chlorine is one of the most widely used disinfectants due to its effectiveness against a broad spectrum of pathogens. However, it is crucial to monitor chlorine levels to avoid the formation of potentially harmful byproducts known as trihalomethanes (THMs). Ozone, a powerful oxidizing agent, is used for its effectiveness in inactivating viruses and bacteria without leaving harmful residues.


  • 2. Organic Chemicals These are primarily derived from carbon-containing compounds and include hydrocarbons and their derivatives. Solvents like ethanol and acetone are commonly used in chemical reactions and for cleaning purposes in various applications. Furthermore, petrochemicals such as ethylene and propylene serve as building blocks for plastics, synthetic fibers, and elastomers.

  • Emulsifiers play a crucial role in the food industry, enhancing texture, stability, and shelf life of various products. One of the most commonly used emulsifiers is E471, also known as mono- and diglycerides of fatty acids. Derived from natural fats, E471 is favored for its ability to create stable emulsions, making it a ubiquitous ingredient in many food items we consume daily.


  • Some studies have indicated that E127, along with other artificial dyes, may be linked to hyperactivity in children and other behavioral issues. Consequently, in countries like the United Kingdom, there are calls for clearer labeling on products containing artificial additives, prompting manufacturers to reconsider the use of such ingredients.


  • In addition to its preservative qualities, sodium citrate serves as a flavor enhancer. It provides a slight tartness that can balance the sweetness in various food products, making it a valuable ingredient in confectionery, sauces, and dressings. Its ability to enhance flavor profiles helps manufacturers create products that are more appealing to consumers, thereby boosting sales and satisfaction.


  • The use of Emulsifier E472 is closely monitored by food safety authorities around the world. In the European Union, for example, E472 has been evaluated by the European Food Safety Authority (EFSA), which has established acceptable daily intake levels to ensure consumer safety.


  • From an environmental perspective, sodium bicarbonate is considered a more sustainable option compared to some synthetic additives. Its production typically involves mining natural deposits or through the Solvay process, which converts sodium chloride and limestone into bicarbonate. As awareness of food sustainability grows, many consumers and producers are leaning toward using more natural additives, and sodium bicarbonate fits this trend.



  • Potassium sorbate is a salt of sorbic acid naturally found in some fruits (like the berries of mountain ash). The commercial ingredient is synthetically produced, creating what is termed a “nature identical” chemical (chemically equivalent to the molecule found in nature). Today, this preservative can be found in wine, cheese, beer, dried meat, soft drinks, and many other food products. This food additive is often used to improve shelf stability and prevent bacteria and mold growth. This ingredient is so prevalent in processed food because it does not change the quality of the product and is also water-soluble. 

  • In conclusion, aspartame stands as a significant player in the realm of food additives and sweeteners. Its ability to provide sweetness without calories makes it a valuable tool for many seeking to reduce their sugar intake. Nevertheless, ongoing research and consumer education are crucial to ensure that individuals are making informed choices about the products they consume. As we move forward, balancing the benefits of aspartame with consumer safety and preference will be essential in shaping the future landscape of low-calorie sweeteners.


  • Despite its advantages, the use of E120 is not without controversy. The reliance on insects for food coloring raises ethical questions, particularly concerning the treatment and harvesting of cochineal insects. Additionally, those following strict vegetarian or vegan diets may avoid E120 due to its animal origin. As a result, the demand for plant-based alternatives is on the rise, and companies are exploring other natural colorants derived from fruits, vegetables, and other plant sources.


  • Preservatives are critical components in food production, playing a vital role in extending the shelf life of products while ensuring safety for consumers. Among these, E621, commonly known as monosodium glutamate (MSG), has garnered significant attention and, in some cases, controversy. Though its primary function is as a flavor enhancer, it is essential to understand its uses, benefits, potential risks, and how it fits into the broader context of food preservation.

  • In addition to leavening, SAPP is often employed in food preservation and to maintain the quality of various products. In the processing of meats, for example, it helps to retain moisture and enhance binding properties in products like sausages and deli meats. Furthermore, it is used in the production of puffed snacks and other processed foods to improve texture and stability, preventing the formation of unwanted lumps.
