Extremely cold ‘cryobits’ accelerate temperature reduction of the packaged product. Ice crystals and air bubbles are significantly smaller with partial cryogenic hardening compared to traditional hardening methods.
The cryogenic freezing of ice cream is appealing because the very rapid temperature drop it produces generates extremely small ice crystals that promote smooth texture and extended textural shelf life. To date, technical, operational and economic factors have limited its use in conventional production to a few value-added products such as novelties and ice cream cakes/pies.
It is not a simple matter when you add nuts, cookies or ribbons to ice cream mix. Pay attention to formulas, overrun, food safety, processing and economics. Proceed carefully and you’ll end up with a great product.
The principles for producing nondairy frozen desserts from vegetable “milks” are the same as for conventional ice cream. However, the challenges are uniquely different. (In this article “milk” will refer to plant-based milks.)
Chocolate is second only to vanilla as the most popular ice cream flavor in the United States. Therefore, it is a major component of the product portfolios of most ice cream companies, representing on average of 8% to 10% of the volume of a typical portfolio.
Greek-style has become short-hand for “double the protein.” Frozen dairy desserts typically are made with flavor in mind. A good-tasting, high-protein dessert is difficult (but not impossible) to develop.
