Mineraux®Sodium malate Health Benefits:

Sodium is the primary positively charged ion in extracellular fluid. It participates in water metabolism, ensuring water balance in the body, regulating water content and osmotic pressure, and maintaining acid-base balance. It is a component of pancreatic juice, bile, sweat, and tears. Sodium is involved in the production and utilization of ATP (adenosine triphosphate), muscle movement, cardiovascular function, and energy metabolism. It is also essential for glucose metabolism and oxygen utilization. It helps maintain normal blood pressure and enhances neuromuscular excitability. A high-sodium diet significantly contributes to calcium loss. Individuals who work in hot temperatures, engage in heavy physical labor, or sweat frequently should supplement sodium (e.g., by drinking light salt water). Sodium deficiency is generally not easily found in the human body. However, it can occur in certain circumstances, such as fasting, eating less, or when dietary sodium intake is very low due to excessive sodium restriction. It can also occur when sodium is lost due to excessive excretion in high temperatures, heavy physical labor, excessive sweating, gastrointestinal diseases, repeated vomiting, or diarrhea. Certain diseases, such as Addison's disease, can cause the kidneys to be unable to effectively retain sodium. Parenteral nutrition can cause sodium deficiency or hyponatremia, and the use of diuretics can inhibit renal tubular sodium reabsorption. Electrolyte supplementation can be achieved through dietary supplements.

Mineraux®Sodium malate is a food additive that combines acidity regulation, flavor enhancement, and nutritional support. Its mild taste and good process compatibility make it widely used in the food industry. Its production and use must comply with strict food safety standards. Sodium malate has excellent dispersibility and water-binding properties in foods, reducing water activity and preventing dehydration. In its natural state, L-malic acid is widely found in fruits such as apples and grapes, while DL-sodium malate is mainly prepared by chemical synthesis, reacting DL-malic acid with a food-grade alkaline source, and meets food-grade raw material standards.

Mineraux®Sodium malate participates in normal metabolic processes in the human body, ultimately breaking down completely into carbon dioxide and water. These are excreted through respiration and excretion, and do not accumulate in the body. For healthy individuals, standard doses pose no toxic risk.

■ Core features

Mineraux®Sodium malate is a weakly alkaline aqueous solution (pH 6.0-7.5), which neutralizes excess acidity in foods and enhances flavor profiles. It also exhibits excellent buffering properties, stabilizing the pH of food systems within a certain range and preventing color and flavor degradation caused by pH fluctuations. It is suitable for a variety of food processing scenarios, including beverages and dairy products. It is highly soluble in water, with solubility increasing with temperature. It disperses quickly and evenly in aqueous food systems without affecting product clarity, making it suitable for liquid food formulations such as beverages and oral liquids. It has a mild sour taste with a slight saltiness, and compared to other pH modifiers, it has less impact on the original flavor of foods, making it particularly suitable for flavor-sensitive products, where it can enhance smoothness. It is stable at room temperature and can help inhibit oxidative spoilage and extend shelf life.

Mineraux®Sodium malate is available in the following specification and contents:

Mineraux®Sodium malate (usually referring to DL-sodium malate) is widely used in the food industry due to its core functions such as mild acidity regulation, flavor improvement, buffering stability and weak chelation, as well as its high safety and friendly taste. It has also been extended to non-food fields such as medicine and cosmetics.

In the food industry, sodium citrate adjusts the pH of the system, mitigates the natural sourness and astringency of juice, and enhances flavor. Through its weak chelating action, it binds to metal ions such as iron and copper in juice, inhibiting polyphenol oxidase activity and preventing browning. It also reduces the oxidative damage of vitamin C by metal ions, thereby extending shelf life. Sodium citrate neutralizes the pungent acidity of carbonic acid, improving the smoothness of the mouthfeel and reducing the risk of tooth corrosion. Its buffering properties stabilize the pH of the system (typically between 4.0 and 5.5), preventing rapid dissipation of bubbles and enhancing the drinking experience. Sodium citrate also helps regulate the osmotic pressure of the system, working with electrolytes such as sodium and potassium to help maintain fluid balance. Its mild taste doesn't interfere with the overall flavor of electrolyte beverages, while also stabilizing the product's pH and preventing spoilage. Sodium citrate can be used in products such as fruit-flavored solid beverages, meal replacement powders, and protein powders to adjust the pH after mixing, improving taste, while preventing oxidation and clumping of ingredients and improving mixing stability.

In the dairy industry, sodium citrate can adjust the pH of the fermentation system, creating a suitable environment for the growth and reproduction of lactic acid bacteria (optimizing the fermentation pH to 4.2-4.5), shortening fermentation time, and improving fermentation efficiency. It also prevents calcium ion precipitation in milk, improves the uniformity of yogurt texture, avoids stratification and clumping, and enhances the product's delicate taste. Sodium citrate can synergize with emulsifiers to improve the emulsification stability of raw materials, prevent oil separation and excessive ice crystal growth, enhance the product's smooth texture and form stability, and prevent stratification and water release after melting.

As an acidity regulator and buffer, sodium malate is used in oral solutions, tablets, capsules, and other formulations to adjust the pH of medications, improve their taste (mitigating bitterness or pungent sourness), and stabilize drug ingredients, preventing them from deteriorating due to pH fluctuations. Some nutritional supplements containing malic acid, in the form of sodium malate, assist in replenishing nutrients needed for metabolism while minimizing gastrointestinal irritation.

■ Production technology characteristics

The industrial production of Mineraux®Sodium malate primarily relies on a chemical neutralization process. The core process includes raw material pretreatment, neutralization reaction, purification, drying, and packaging. Strict process parameters must be controlled throughout to ensure product quality.

The core raw materials are food-grade DL-malic acid and an alkaline source (sodium carbonate, sodium hydroxide, etc., both meeting food-grade standards). Deionized water is used as the reaction medium to prevent the introduction of impurities. The raw materials are pretreated to remove harmful substances such as heavy metals (lead, arsenic, etc.), chlorides, and sulfates through filtration and ion exchange. DL-malic acid is dissolved in deionized water to prepare an aqueous solution of a desired concentration. The alkaline source solution is slowly added while stirring to avoid excessive localized reactions. The reaction temperature is adjusted to 50-70°C, and the pH is maintained between 6.5 and 7.5 to ensure sufficient reaction between the DL-malic acid and the alkaline source. After the reaction, the reaction solution is filtered while hot to remove unreacted solid impurities and trace precipitates formed during the reaction, yielding a clear crude sodium malate solution. The clarified crude liquid is fed into an evaporator to evaporate water until the solution reaches a supersaturated state, minimizing the effects of high temperatures on the product. The concentrated, supersaturated solution is transferred to a crystallizer and slowly cooled to 20-30°C to promote uniform precipitation of sodium malate. Some processes may include the addition of seed crystals to guide crystallization, improving crystal purity and yield. The crystallized product is centrifuged to obtain a crystal cake. This cake is then washed with a small amount of cold deionized water to remove unreacted raw materials and impurities adhering to the surface, further enhancing product purity. The washed crystals are dried in a vacuum oven or airflow dryer at 60-80°C in a low-humidity environment to control the moisture content to meet standard requirements and prevent high-temperature-induced crystal decomposition. The dried crystals are crushed and sieved according to market demand to produce products of varying particle sizes to meet the needs of various applications, such as beverages and baking.

Mineraux®Sodium malate's aqueous solution is weakly alkaline. The alkaline products produced after metabolism can neutralize some of the acidic substances produced by long-term consumption of highly acidic foods (such as meat, refined rice and flour, and processed foods), helping to maintain a stable acid-base environment and reducing the burden of an acidic constitution.

▶ Assists in regulating acid-base balance

Mineraux®Sodium malate has a weak chelating ability for some metal ions, such as iron and copper. In the intestines, it can combine with harmful heavy metal ions, such as lead and mercury, to form stable, poorly absorbed chelates, which are then excreted in feces. This reduces the accumulation of these heavy metals in the body and plays a certain role in detoxification.
