The functional solid beverage industry frequently adds magnesium citrate for magnesium fortification. Food-grade magnesium oxide serves as the core raw material for preparing this type of magnesium citrate, profoundly influencing the quality performance of the finished solid beverage. Sports nutrition solid beverages, composite mineral drink mixes, and meal-replacement solid beverages all select magnesium citrate as their magnesium source. The water solubility of magnesium citrate is superior to that of many other magnesium salts; when added to solid beverages, it does not produce a large amount of sediment upon reconstitution with water, thereby preserving the appearance and mouthfeel of the drink. To obtain magnesium citrate suitable for solid beverages, the particle size, purity, and reactivity of the magnesium oxide raw material must match the corresponding processing conditions.
For Messi Biology’s food-grade magnesium oxide, the powder particle size range can be adjusted on demand. Fine-grained magnesium oxide provides sufficient contact area with citric acid, allowing the neutralization reaction to proceed thoroughly. The synthesized magnesium citrate features delicate crystals, reduces the difficulty of subsequent pulverization processing, exhibits good dispersion performance upon reconstitution when formulated into solid beverage ingredients, and minimizes sediment at the bottom of the cup. If the magnesium oxide particles are coarse and the reaction is incomplete, the finished magnesium citrate will be mixed with unreacted particles. When added to solid beverages, mixing with water will result in noticeable sedimentation, negatively affecting the consumer’s drinking experience.
Solid beverages cater to the mass consumer market, requiring raw materials that comply with national food safety standards. Furthermore, many brands have export demands, necessitating compliance with certifications such as REACH and KOSHER. Messi Biology’s food-grade magnesium oxide has obtained multiple international authoritative certifications and comes with complete batch documentation, facilitating downstream solid beverage raw material plants in completing compliance declarations. Some solid beverage clients require magnesium citrate to have good anti-caking properties; Messi Biology can indirectly optimize the powder fluidity of magnesium citrate by adjusting the indicators of magnesium oxide, thereby reducing moisture absorption and caking issues during storage and transportation. Messi Biology’s digitalized supply chain platform guarantees stable raw material delivery, while relying on the “top executive + triangular team” service model to provide diagnostic technical services. When clients encounter production problems such as poor magnesium citrate dissolution or high moisture absorption, the team responds rapidly, collaborating with clients to trace the root causes from the raw material end, optimize processes, and help solid beverage supply chain enterprises stably produce qualified magnesium citrate raw materials.
