About our Food Testing Services and what is required
We offer a team approach to provide food testing services and specialize in working with small and start-up food businesses. While our primary mission is to support Maine and New Hampshire food businesses, we also work with businesses across the U.S. and are recognized process authorities by the FDA. Our process involves submission of your batch recipe, detailed processing methods, and 1 sample in the final product container.
- Kathy Dentici, Research Assistant and Laboratory Manager. Kathy conducts the food testing.
- Dr. Beth Calder and Dr. Jason Bolton, process authorities and primary contacts for questions regarding testing, test results and process reviews. Beth reviews the formulations and processing methods submitted and writes individualized and comprehensive review letters back to clients. The review letters are automatically emailed to the client as soon as they are completed. Our turnaround time is dependent on the volume of products sent in for testing, but is typically 4-6 weeks.
We provide testing and process reviews on shelf-stable, canned foods, lacto-fermented vegetable products, water-activity controlled dessert sauces, frostings/fillings, high moisture baked goods, and minimally processed dried food products. We do not provide process reviews for alcohol-based products, herbal tinctures or beverages. Buttercream frostings, baked goods, and fermented foods must be scheduled ahead of time with Beth before being mailed in.
We do not provide testing or process reviews on perishable (frozen or refrigerated foods) or meat and poultry products. We also do not provide testing for kombucha, fermented beverages or beverage products. We do not provide testing for cold filled, shelf stable products, except for mayonnaise. We do not provide shelf-life tests or nutritional facts labels. We can perform testing on lacto-fermented vegetable products that are refrigerated or shelf stable.
- Pickled foods (acidified foods) and most sauces/dressings will require both pH and water activity tests.
- Jams, jellies, fruit butters and applesauce products will require pH, water activity and Brix tests.
- Dessert sauces (caramel and chocolate) will require Brix and water activity tests.
- Fermented foods will require pH and titratable acidity tests.
- Food samples that do not typically require a review in Maine are baked goods (without dairy-based fillings/frostings); candy/confections; plain, berry-based jams/jellies (strawberry, blackberry, blueberry or raspberry); and dry spice mixes/rubs. If you have any questions in regards to jam or jelly testing or processing requirements, please contact either Beth or Jason.
If you have any questions in regards to which tests may be required or if we can analyze your food product, please contact Beth or Jason prior to submitting and paying for samples online. Please see our contact information below.
Our current turnaround time may vary due to the pandemic and product volume sent in for testing, but is typically 4-6 weeks. We appreciate your patience. We provide these services on a part-time basis around our research, outreach, and teaching schedules. Our laboratory observes federal holidays and will be closed on those days and weekends. The laboratory is also open during limited times after December 25 for inventory purposes and will resume our normal testing schedule on January 2.
If you have any questions about whether you should send in a product for testing, which tests are required for your product, or how to start a food business in Maine, please contact Beth Calder or Jason Bolton.

- REQUIRED: The batch recipe ingredients must be converted onto a weight basis (including fluids) and all the same unit (grams, ounces or pounds). The most accurate method is to purchase a scale that is accurate to 0.1 +/- the unit of measure to individually weigh out the ingredients. Please check that ingredients have been entered correctly to ensure no delays in the testing process.
- The online form will require you to include your full name, company name (if applicable), email, mailing address, and phone number.
- Your email address is required, as we will send all results electronically via email to the person listed on the account.
- One product in the final container must be sent to our laboratory. For water bath-processed foods, if you intend to sell your product in several different container sizes, please submit one (1) sample of each container size.
- Detailed description of how each product is produced, including vegetable preparation (if applicable) and heating temperatures and times.
- Be sure to place an identifying label on each product.
- Include a business card or note with name and address when mailing in samples.
- For ready-to-eat and minimally processed foods, you may need additional microbial testing.
- Payment: We now require payment with a credit card or electronic check made payable to the “University of Maine.” If you are having issues with your online payment or with login and password issues, please contact Michele Lodgek at 207.581.2721 or firstname.lastname@example.org.

Our laboratory is not responsible for additional shipping costs if containers are received broken and/or returned by shipping companies due to broken containers. It will be the client’s responsibility to resend samples to our laboratory for testing if samples are received damaged.
