Stretchability, meltability, and viscosity ... that's how the Kantner Group measures its dairy-based products. The company makes cheese-making ingredients, such as milk proteins and replacers, rennet, whey, cheese powders and analogues, and starter media. Its other products include ice cream and shake mixes. The company also offers private-label and custom-blending, and -packaging services. Kantner owns cheese-manufacturing companies Blue Valley Foods and Chianti Cheese. Chianti makes Italian specialty cheeses; Blue Valley also makes Italian cheeses, plus Cheddar and Jack. Kantner's customers include food retailers and manufacturers and foodservice providers. The firm was founded by CEO Doug Kantner in 1999.
