The food additive caustic soda (sodium hydroxide, NaOH) is itself highly alkaline and corrosive, and can cause harm to the human body if not used correctly or if it comes into contact with the skin, eyes, or its dust is inhaled. However, in the food industry, when sodium hydroxide is used as a processing aid, its safety depends on how it is used and how the final product is handled. Safety considerations 1. Proper use: During food processing, sodium hydroxide must be used according to strict standards to ensure that there is no residue in the final product or the residue is within a safe range. 2. Professional operation: Any operation involving sodium hydroxide must be performed by specially trained personnel and take appropriate safety measures, such as wearing protective equipment (gloves, goggles, etc.). 3. Regulatory compliance: The use of sodium hydroxide must comply with local food safety standards and regulations to ensure that its application in food processing is safe. Safety measures 1. Accurate measurement: When using sodium hydroxide, its dosage must be accurately measured to avoid excessive use and residue problems. 2. Dissolution and dilution: Sodium hydroxide is usually dissolved in water to make a solution before use to ensure uniform distribution and reduce risks. 3. Thorough cleaning: After the processing is completed, it is important to ensure that the food is thoroughly cleaned to remove any residual sodium hydroxide and to ensure that there is no residue or the amount of residue is within a safe range in the final product. Food Safety Regulations When sodium hydroxide is used as a processing aid in the food industry, it must be ensured that it complies with food safety regulations. This means that there should be no residue or the amount of residue must be within a safe range in the final product. Each country and region has its own food safety standards. Summary When sodium hydroxide is used as a processing aid in the food industry, it can be guaranteed to be safe if the correct usage and safety measures are followed. Its use is strictly controlled and it must be ensured that the final product is harmless to the human body. If there is any doubt about whether sodium hydroxide is used in a specific food, it is recommended to check the ingredient list of the food or contact the manufacturer for detailed information. Important Tips • Safety: Sodium hydroxide is highly corrosive and must be handled with care. • Regulatory compliance: Any process using sodium hydroxide must comply with food safety regulations and ensure that there is no residue or the amount of residue is within a safe range in the final product. • Professional operation: Operations using sodium hydroxide must be carried out by trained professionals and appropriate safety measures must be taken.

There are several key differences between food additive caustic soda (food-grade sodium hydroxide) and industrial caustic soda (industrial-grade sodium hydroxide), which mainly involve purity, use, and safety standards: 1. Purity • Food-grade caustic soda: Sodium hydroxide used in food processing must meet food-grade standards, usually with high purity and free of harmful impurities. It must meet national and international food safety standards. • Industrial-grade caustic soda: Sodium hydroxide used in industrial production has relatively low purity and may contain various impurities, such as heavy metals, chlorides, etc. These impurities may pose a risk to food safety and therefore cannot be used in food processing. 2. Uses • Food-grade caustic soda: It is specifically used in food processing and production, mainly for adjusting pH, peeling, improving food texture and appearance, etc. Its application requires compliance with strict usage and handling standards to ensure food safety. • Industrial-grade caustic soda: It is used for various industrial purposes, such as chemical manufacturing, cleaning, papermaking, oilfield chemicals, etc. Its use areas do not involve direct contact with food, so the purity requirements are lower. 3. Safety standards • Food-grade caustic soda: Strict food safety regulations and standards must be followed during production and use to ensure that there is no harm to consumer health. The caustic soda must be thoroughly cleaned or neutralized after use to ensure that the residual amount in food is within a safe range. • Industrial-grade caustic soda: Since it is not used in food production, its safety standards focus mainly on industrial production safety rather than food safety. The purity and safety requirements in its production and use are lower. 4. Production and processing • Food-grade caustic soda: Strict hygiene standards must be followed during production and processing to avoid any possible contamination and ensure that it meets food-grade quality requirements. • Industrial-grade caustic soda: Food safety standards do not have to be met during production and processing, and can be carried out under more relaxed conditions. Summary The main differences between food-grade caustic soda and industrial-grade caustic soda are purity, use, and safety standards. Food-grade caustic soda must meet high purity requirements and follow food safety regulations to ensure safe use in food; while industrial-grade caustic soda has lower purity and is used for non-food related industrial purposes.

Storing PVC figures requires a few considerations to ensure their longevity and preserve their appearance. Firstly, it's important to keep them away from direct sunlight, as UV rays can cause discoloration and degradation. Ideal storage areas include shelves or cabinets with doors that provide some protection from light and dust. Additionally, maintaining a stable room temperature and low humidity levels can prevent warping or other damage. If the figures need to be stored in boxes, using acid-free tissue paper can offer extra protection against scratches or paint transfer. Avoid wrapping them in plastic bags that can trap moisture, leading to mold. For long-term storage, periodically check the figures and their storage environment to make adjustments as necessary.

Yes, you can use emulsions in royal icing to introduce flavors beyond the traditional vanilla. Emulsions, which are water-based as opposed to oil-based like most extracts, mix well with the water content of royal icing. This compatibility ensures that the icing's texture is not compromised. However, it's essential to start with small amounts and taste as you go, because emulsions can be more concentrated and impart a stronger flavor than extracts. Additionally, since they are water-based, they won't affect the icing's drying or setting properties, making them a versatile choice for customizing flavors in your icing creations.
