For example, Monroe, Wis.-based Glanbia Nutritionals produces Thermax® 690, a whey protein that stands up to heat. This whey protein isolate is stable in low-acid aseptic and retort beverages at protein concentrations of 10% or more. While typical whey proteins might gel and precipitate, this ingredient yields a clear beverage that looks very appealing in glass or clear plastic containers.
Food manufacturers that want to increase the per-serving protein level in high-heat-pasteurized drinks or foods can also look to Leprino Foods, Denver. Leprino's new Temp Pro™ 80 is ideal for beverages, having been formulated to withstand the high heat of ultra-high-temperature (UHT) and retort processes previously limited to other, more expensive proteins and isolates. This ingredient also works well in other UHT-processed foods such as puddings, sauces and yogurts, as well as in high-acid foods and beverages.
