Fermentation Science, B.S.

MTSU’s new Fermentation Science major is the first degree program of its type in Tennessee and rare in the Southeast region. Fermentation is now understood to be an ideal vehicle for the production of highly nutritious and long-term stable foods with unique flavors, textures, and aromas. Tennessee is home to a large and diverse community of food processors, and the most significant growth has been in the fermented foods segment of this vitally important industry. Courses in Fermentation Science will be taught in partnership with local companies, and hands-on training sessions at industry sites as well as internships will be scheduled to accommodate both working professionals and traditional students. Tennessee hosts 60 wineries, 30 distilleries, 52 breweries, 10 cheese-making operations, the largest yogurt manufacturing plant in the world, additional smaller yogurt producers, and two major ethanol production facilities.

Alumnus Mark Jones (’90) founded Steel Barrel Brewing Co., a new 82-acre agribusiness enterprise opening in Murfreesboro in 2017. (Think Arrington Vineyards, only serviced by a brewery instead of a winery and raising hops instead of grapes.) The business will also serve as the location of MTSU’s new fermentation lab and sensory lab—a kind of “psychological space” highlighted by blind testing, tasting, and smelling activities. The cutting-edge facility is starting up just as MTSU launches the Fermentation Science program. “It’s almost meant to be, the way things are laying out,” Jones said. “Part of the new degree requires internships, and we can give students hands-on, real-world opportunities, as well as prepare what will become a qualified labor force for us.” The beer industry, which also includes the growing craft brewing segment, had a combined economic impact of $252.6 billion across the U.S. in 2014.

Fermentation is old and new at the same time

While the practice of fermenting foods dates back 8,000 years or so, the science behind the processes continues to evolve. And the search for bolder flavor and better nutrition in the U.S. is increasing the demand for familiar fermented foods like sourdough bread, as well as food products native to other countries such as kefir, miso, and pickled fruits and vegetables. “The science behind brewing beer and fermenting foods is largely the same,” program director Tony Johnston said. “We use microorganisms such as yeast, bacteria, and mold to create foods we like to consume—cheese, sour cream, buttermilk, yogurt, sauerkraut, summer sausage, pickles, kimchi.” Fermentation has the capability to produce probiotic compounds in foods, as well as convert sugars into acids that are “much better for us,” Johnston said. It’s also the only food preservation technique that doesn’t require the input of energy.

The explosive growth of the fermented foods and fermentation-derived energy over the last 20 years indicate significant potential for employment of graduates with the proposed degree. Fermented food manufacturers of every type need college graduates with specialized training who can enter the workforce ready to sustain and advance the industry. The B.S. in Fermentation Science addresses both the current, pressing needs of local industry and creates new opportunities for highly trained food industry specialists who could transition from one type of fermented food industry to another. A 2014 survey by the Master Brewers Association of the Americas (MBAA) shows a preference for a four-year degree for management and leadership positions, as well as for brewmasters or head brewers. Other positions where a four-year degree is indicated includes quality positions, brewery positions, lab technicians, and engineers. Job titles graduates may choose to pursue

  • Biomanufacturing operator
  • Bioprocess engineer/scientist/researcher
  • Brewer (assistant/associate/lead/master)
  • Brewery operations director
  • Cellar technician/manager/operator
  • Distiller (assistant/associate/master/head)

MTSU offers the Bachelor of Science (B.S.) in Fermentation Science, a new program in the School of Agribusiness and Agriscience.

Within agriculture, fermentation science is one of the two fastest-growing areas of interest with the most immediate impact on the well-being of humanity. Program director Tony Johnston holds a doctorate in Enology and Viticulture and has worked extensively in the fermented foods industry.

Other majors in the School of Agribusiness and Agriscience leading to a B.S. are Agribusiness, Animal Science, Horse Science, and Plant and Soil Science. Students may also take courses in pursuit of an Agricultural Education Certificate. Undergraduate and graduate minors are available in Agriculture.

Graduate study includes the Master of Education (M.Ed.) in Administration and Supervision with a concentration in Agricultural Education Leadership and a Master of Science (M.S.) in Horse Science with concentrations in Equine Education, Equine Physiology, and Industry Management.
