These days, terms such as keto, paleo, high-protein, plant-based, vegan, even "pegan" (paleo-plus-vegan), describe not just diets but entire lifestyles.

Texturally speaking, "ice cream" is something of a misnomer. Yes, consumers expect the frozen treat to be creamy; but any hint of actual iciness, either in the scoop or on the palate, qualifies as an unmistakable quality flaw.

Over the past few years, freezer cases have been filling up with a new class of creamy, dreamy treats that bear all the hallmarks of sinful indulgence while delivering more pluses (think protein and fiber) and fewer minuses (added sugar or "artificial" anything), to boot.

Consumers seek simple ingredient legends and want indulgent flavors. Gelato offers both.

Healthy indulgence, unique and seasonal flavors and clean labels are all part of the focus for frozen dessert processors.
