Quality

Quality

In order to ensure quality in our products, we set high quality specifications and buy direct from responsible, sustainable sources — certified organic whenever possible. We handle product carefully from receiving to shipping to maintain quality and do extensive product testing to guarantee safe, high-quality products.

You can trust our products. We have the skills resources necessary to find and buy top botanical products from around the world — and to make sure that those products have no adulteration, fillers or questionable ingredients. And we never make false or empty claims about our products.

We always search for the best-tasting spices and most pure oils. We have 100% ingredient disclosure and formulate our products as naturally as possible.

Sourcing

Quality begins with skillful, knowledgeable buyers traveling the world and forming meaningful relationships with growers and sources committed to quality themselves and long-term partnerships. We know the decisions we make at the sources of our products directly impact how good our products are on the shelf. We work with our sourcing partners to get those first decisions right — fennel that's grown and processed for quality in Turkey,  buying flat-leaf parsley for its superior flavor, lovingly grown rosemary, and Ceylon cinnamon that's specially handled for purity and high oil content, for example.

Whenever possible, we support growers expanding their organic agricultural production, both with secure long-term contracts and by funding their expansion into more products as we did with Pacific Northwest herb grower Aromatics.

And we maintain stable, quality sources for our products by building long-term sourcing partnerships and improving the lives of our growers, their communities and the environment.

Handling

Once herbs and spices arrive at Frontier, every aspect of their handling is done with quality in mind.

• Climate controlled storage (70 degrees Fahrenheit and 60% relative humidity) to preserve freshness and chemically active plant constituents.
• Strict sanitation rules enforced through regular inspections by Quality Assurance.
• Product handling, processing and packaging systems set up to maximize the quality of the final product.
• Exposure to moisture and heat minimized at all times. Grinding of spices and herbs is done cryogenically at temperatures below -20 degrees Fahrenheit.
• We use a sophisticated computerized inventory system that allows any herb or spice, even a minor ingredient in a blend, to be instantly located or traced back to its origin.
• Herbs and spices are packaged in materials that ensure the optimum quality of a product -- foil laminate pouches, glass bottles, or plastic bags double-bagged in paper.
• Frontier does not sell any products or use any ingredients that have been sterilized by irradiation or ethylene oxide (ETO). We utilize safe and effective steam sterilization to preserve product quality (see below).
• Processes are in place to prevent allergen contamination and allergens are identified on labels if present.
• Each of our items is freshness dated with a use-by date that ensures maximum flavor.

Testing

Our highly qualified Quality Assurance staff — a team of trained technicians led by Ravin Donald, Ph.D. — tests products thoroughly upon their arrival and throughout their processing and packaging here at our facility. Here are some of tests we use to ensure we're providing you with the best natural products available:

• HPLC (high performance liquid chromatography) testing measures active constituent levels in herbs.
• Microanalysis reveals cellular structure of plants to determine identity and adulteration.
• Microbiological testing detects yeast, mold and bacterial pathogens.
• Organoleptic testing consists of taste, smell and sight tests to determine quality and screen out adulterated product.

Steam Sterilization

A key safeguard of product safety is sterilization to eliminate pathogens such as Salmonella. We employ SteamSafe®, a state-of-the-art steam sterilization system that allows us to offer safe, flavorful spices to our customers without using irradiation or ethylene oxide (ETO), a chemical that cannot be used on organic products.
