Product Introduction
Riboflavin sodium phosphate, also known as flavin mononucleotide (FMN) sodium, is a derivative of riboflavin (vitamin B2) that is more soluble in water. It is produced by phosphorylating riboflavin and then converting it into its sodium salt form [1]. The main components include riboflavin and phosphate groups. Riboflavin is sourced from microbial fermentation or chemical synthesis [2]. This compound is utilized as a food additive for color enhancement and nutritional fortification [3]. It also functions as a nutrient in pharmaceuticals and dietary supplements, particularly in applications where high water solubility is required [4].
Production Process
The production of riboflavin sodium phosphate typically involves several steps. First, riboflavin undergoes phosphorylation using a phosphorylating agent. This phosphorylation process attaches a phosphate group to the riboflavin molecule [5]. Next, the phosphorylated riboflavin is converted to its sodium salt form through the addition of a sodium base, such as sodium hydroxide. Finally, the resulting riboflavin sodium phosphate is purified, isolated, and dried to obtain the final product [6].
Application Scenarios
In the food and beverage industry, riboflavin sodium phosphate is used as a color additive to impart a yellow or orange-yellow hue to food products. It can be added to dairy products, beverages, cereals, and sauces to enhance their visual appeal [7]. Due to its high water solubility, it is very useful in liquid formulations. Furthermore, it functions as a nutrient, supplementing the riboflavin content of food, which is beneficial for overall health [8]. In the pharmaceutical industry, riboflavin sodium phosphate is used in vitamin supplements and therapeutic formulations, especially where an injectable form of vitamin B2 is needed [9].
Packaging and Storage
Riboflavin sodium phosphate should be packaged in tightly sealed containers to protect it from light, moisture, and air. Proper packaging helps maintain the product's stability and prevents degradation [10]. It should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances. The recommended storage temperature is generally below 25°C. Under these conditions, the product can maintain its quality and efficacy for its stated shelf life [11].
