What is Zemea® USP-FCC Propanediol?

Zemea® propanediol is a naturally-derived, petroleum-free ingredient produced through the fermentation of corn sugar. The specific food-grade variant, Zemea® USP-FCC, adheres to the rigorous standards of the United States Pharmacopeia (USP) and the Food Chemicals Codex (FCC). This bio-based ingredient serves as a versatile alternative to traditional petroleum-based carriers and additives, such as propylene glycol (PG), in the food and flavor industry.

Key Functions in Food and Beverages

Zemea® USP-FCC performs several important functions that improve the quality and characteristics of food products:

Carrier and Solvent: Effectively dissolves and disperses flavors, extracts, and colors, ensuring even distribution throughout the product.
Taste Modifier: Helps reduce the bitterness and enhance the perception of sweetness in beverages, dairy, and other items.
Humectant: Assists in retaining moisture, which is especially beneficial for baked goods, icings, and cream fillings.
Antimicrobial Properties: Lowers water activity in formulations, which can boost the efficacy of preservatives.
Processing Aid: Facilitates the dissolution of complex ingredients like polymers or gums, preventing clumping.

The Safety Profile and Regulatory Approvals

The safety of Zemea® USP-FCC is supported by a comprehensive regulatory and certification framework. Its producer, Primient Covation (formerly DuPont Tate & Lyle Bio Products), has pursued and received significant endorsements from major food and flavor regulatory bodies.

Regulatory Certifications for Food-Grade Zemea

FDA GRAS Non-Objection: The manufacturer has self-affirmed Zemea® USP-FCC as Generally Recognized as Safe (GRAS), and the U.S. Food and Drug Administration (FDA) issued a letter of no objection to this status.
FEMA Approval: It is certified as GRAS by the Flavor & Extracts Manufacturers Association (FEMA) under FEMA #4753, confirming its safe use as a flavoring ingredient.
USP-FCC Compliance: The ingredient is tested and certified to meet the standards of the Food Chemicals Codex (FCC) and the United States Pharmacopeia (USP) for food-grade substances.
100% Bio-based: The U.S. Department of Agriculture (USDA) has certified it as a 100% bio-based product, emphasizing its renewable source.
Other Certifications: Zemea® has also earned certifications for kosher, halal, and gluten-free diets, further expanding its safe applications.

Zemea vs. Propylene Glycol: A Safety Comparison

One of the main reasons Zemea was developed was to offer a safer, more sustainable alternative to petroleum-derived propylene glycol (PG). While PG is also considered safe for food use, studies show Zemea® presents some distinct advantages.


Feature	Zemea® USP-FCC (Propanediol)	Propylene Glycol (PG)
Source	100% Plant-based (fermented corn sugar)	Petroleum-based
Toxicity	Non-toxic	Low toxicity, generally safe in regulated amounts
Environmental Profile	Favorable; significantly lower greenhouse gas emissions	Less favorable; petroleum-derived
Skin Irritation	Minimal to no skin irritation or sensitization, even at high concentrations	Can cause skin irritation at higher concentrations in some individuals
Taste Profile	Neutral, with benefits like reduced bitterness	Can impart a noticeable taste or chemical off-taste
Humectancy	Excellent humectancy properties	Good humectancy

Environmental Profile and Sustainability

Beyond safety, Zemea's production method offers significant environmental advantages. The fermentation process uses sustainably sourced plant-derived glucose, leading to a smaller carbon footprint compared to petroleum-based alternatives. Life Cycle Assessment data indicates that its production generates up to 40% less greenhouse gas emissions. As consumers increasingly seek transparent, eco-friendly ingredients, Zemea provides a way for food manufacturers to meet these demands without sacrificing product performance.

Conclusion: A Safe and Sustainable Choice for Food

In conclusion, the question, "Is Zemea safe in food?" can be confidently answered with a 'yes,' particularly regarding the food-grade USP-FCC version. Supported by extensive third-party testing and certifications from key regulatory bodies like the FDA (via GRAS non-objection), FEMA, and FCC, Zemea® USP-FCC has demonstrated its safety for use in a wide range of food and flavor applications. Its plant-based origin makes it a sustainable and pure alternative to petroleum-derived glycols, addressing both safety concerns and growing consumer preferences for natural, eco-friendly ingredients. By offering a neutral taste profile, enhanced sweetness, and superior humectancy, Zemea provides a high-performing and certified safe option for modern food technologists and flavorists.
