1.What is electrolyte water?
According to the "Electrolyte Beverage" (T/CBIA 012-2024) group standard organized by the China Beverage Industry Association, an electrolyte beverage refers to a beverage that adds sodium salts, potassium salts and other soluble salts as well as other nutrients required by the body, and can replenish the electrolytes and water in the body fluids consumed during metabolism (such as water loss through sweat) for the body. Currently, the common electrolyte beverages on the market can be classified into several major categories: electrolyte beverages, sports beverages, solid beverages, and sports nutrition foods.
2.The nutritional components and efficacy of electrolyte water
Electrolyte water usually contains trace elements such as potassium, calcium, sodium, and magnesium, as well as proteins, fats, glucose, etc. It can maintain the osmotic pressure balance and acid-base balance of body fluids, maintain the resting potential of nerve, muscle, and cardiac muscle cells, and participate in the formation of action potentials. By participating in the absorption and utilization of sugar, proteins, and fats, it promotes the metabolism of the human body and maintains physiological activities.
3.The main functions and benefits of electrolyte water
After exercising, the human body loses a large amount of electrolytes and water through sweating. Drinking electrolyte water can quickly replenish these lost substances, maintain the normal physiological functions of the body, relieve fatigue, and improve athletic performance. In hot environments, the body sweats more, and electrolyte water can help maintain the electrolyte balance in the body and prevent heatstroke. For cases of electrolyte imbalance caused by fever, vomiting, diarrhea, etc., electrolyte water can also play a certain role in supplementation and regulation.
Applicable Population and Drinking Recommendations
It is not recommended to drink electrolyte water for a long time, and even more so, electrolyte water should not be used as regular water. Doing so may lead to excessive intake of electrolytes by the body, causing electrolyte imbalance.
4.What product categories and requirements does "electrolyte water" have?
01.The basic requirements for label identification
According to GB 7718-2011 "Food Safety National Standard - General Rules for Labels of Prepackaged Food", food labels must clearly indicate the specific name that reflects the true attributes of the food in a prominent position. The specific name can be selected from the names stipulated in national standards, industry standards or local standards. Therefore, enterprises and consumers need to clearly identify the true product category of "electrolyte water" available on the market.
02.Common product categories of electrolyte water
At present, the so-called "electrolyte water" products on the market can be mainly classified into the following categories:
A.Electrolyte beverages: They belong to special-purpose beverages (GB/T 10789-2015), referring to products that add appropriate nutrients or specific ingredients to provide energy for the body or accelerate energy absorption.
B.Sports drinks: Adapted to the physiological characteristics of athletes, they can replenish water, electrolytes and energy (GB 15266-2009).
C.Solid beverages: Include special-purpose solid beverages (such as electrolyte solid beverages, sports solid beverages).
D.Sports nutrition food: It falls under the category of special dietary food (GB 24154-2015), specifically designed for people who engage in sports (exercising at least 3 times a week, each session lasting at least 30 minutes, with moderate intensity or above).
5.Do the relevant standards have specific requirements for electrolyte water?
Take sports drinks as an example. According to the standard GB 15266-2009 "Sports Drinks", the sodium content should be within 50 - 1200 mg/L, equivalent to 5 - 120 mg/100 ml; the potassium content should be within 50 - 250 mg/L, equivalent to 5 - 25 mg/100 ml. In addition, there are requirements for the content of soluble solids, which should be within 3.0% - 8.0%. For electrolyte solid drinks, GB/T 29602-2013 "Solid Drinks" stipulates that by adjusting the types and contents of nutrients in the drink, or adding solid drinks with specific functional components that meet the needs of the human body, such as sports solid drinks, nutrient solid drinks, energy solid drinks, and electrolyte solid drinks, etc.
In conclusion,electrolyte water, as a nutrient-rich beverage, is playing an increasingly important role in people's lives.
