Hydroxypropyl Methylcellulose (HPMC) is a nonionic cellulose ether obtained by chemical modification of natural plant cellulose. It is widely used in food, medicine, cosmetics, building materials and other fields.
1. Source and structural characteristics of HPMC
HPMC is a water-soluble polymer compound made by methylation and hydroxypropylation reaction based on natural cotton, wood pulp and other plant fibers. It does not contain animal ingredients and does not involve genetic modification. Therefore, it is used as an additive in food and is suitable for a variety of dietary habits such as vegetarian, halal, and Jewish diets.
The main functions of HPMC are thickening, film formation, stable emulsification, controlled release, etc. Due to its good thermal stability, low calories, and indigestion and absorption by the human body, it has become a commonly used functional additive in the food industry.
2. International food safety certification and regulations allow
HPMC has been recognized as a safe and edible additive by food and drug administrations in many countries and regions, as follows:
The Joint Expert Committee on Food Additives (JECFA) of the Food and Agriculture Organization/World Health Organization (FAO/WHO) of the United Nations
lists HPMC as a thickener, emulsifier and stabilizer that can be used in food, and there is no daily intake limit (ADI not specified), indicating that the toxicity is extremely low.
The U.S. Food and Drug Administration (FDA)
classifies HPMC as GRAS (Generally Recognized As Safe), allowing it to be used in food, medicine, health products and other fields.
European Union (EU)
Under the European Food Additives Regulation No. E464, HPMC is approved for use as a food additive.
China National Food Safety Standard (GB2760)
Clearly lists HPMC as a food additive, which can be used in capsule shells, low-fat foods, pasta products, dairy products, frozen foods, etc., and specifies the scope of use and maximum usage.
3. Toxicological studies and biological safety analysis
The biological safety of HPMC has been confirmed by multiple animal experiments and clinical tests:
The results of toxicity tests show extremely low toxicity: Acute, subacute and chronic toxicological studies have shown that no obvious adverse reactions were observed even when a large dose of HPMC was ingested.
Not digested and absorbed by the human body: HPMC will not be decomposed and absorbed by gastrointestinal enzymes, so it does not participate in energy metabolism and will not cause blood sugar to rise. It is suitable for people with diabetes or people who want to lose weight.
No carcinogenicity, no teratogenicity, no genotoxicity: Long-term intake has not shown any evidence of carcinogenicity or genotoxicity.
4. Typical application examples in food
HPMC is widely used in food, and common uses include:
Vegetarian capsules: HPMC is the preferred material for making plant capsules, replacing traditional gelatin, suitable for vegetarians.
Low-fat/meal replacement foods: used to simulate the taste of fat, increase thickness and satiety, commonly found in low-fat ice cream, protein bars, nutritional milkshakes, etc.
Noodles: Adding HPMC to noodles and bread can improve elasticity, anti-aging, taste and moisture retention.
Quick-frozen foods: Improve the texture stability of food during freezing and thawing.
Dairy products and beverages: Used for emulsification, suspension and stabilization of emulsions, such as lactic acid bacteria beverages, protein beverages, etc.
5. Are there any risks or allergy issues?
In general, HPMC has very low allergenicity because it is a high-purity plant-derived compound that basically does not contain protein and will not cause allergic reactions. In very rare cases, if an individual is extremely sensitive to cellulose additives, it may cause mild gastrointestinal discomfort (such as bloating and increased flatulence), but this can usually be alleviated by reducing the dosage or stopping consumption.
6. HPMC is safe and edible, with broad application prospects
Hydroxypropyl methylcellulose (HPMC), as a functional food additive with natural origin and safety verification, is widely recognized as safe for consumption both internationally and domestically. It has the advantages of being non-toxic, non-allergenic, non-absorbable, and having diverse functions, and has become an indispensable part of the food industry.
