Q&A's On Ice Cream
Effect of Mix Composition on Flavor:
What is the effect of base mix composition on ice cream flavor delivery?
Answer: Ice cream flavor includes taste (sweet, salty, bitter, sour and savory) and aroma. The importance of the base mix composition on flavor delivery in the finished product cannot be understated.
Flavor and functional quality of base mix ingredients, as well as other factors such as the amount, type and ratios of various ingredients including sweeteners, fat, protein, bulking agents, salts, and the direct and indirect impact of emulsifiers, stabilizers, ice and overrun all affect the finished product flavor. Amount (intensity) and type (quality) of any given flavoring ingredient are also important. Anything that modifies these elements inherently modifies perception, quality and overall acceptability of flavor.
Although theoretical sweetness offers a good way to measure sweetness, each individual sweetener, or blend of sweeteners, yields a different sweetness profile, including a variety of aftertastes, which may or may not be compatible with the characterizing flavor of the finished ice cream.
Milkfat, cocoa butter, egg yolk and other added fats are good carriers of a variety of fat-soluble flavor chemicals. They can help to mask various undesirable flavors but are also potential sources of off flavors. Thus, fat can significantly modify the delivery of flavor. Some flavors that are desirable in high-fat mixes may not be very desirable in low-fat mixes. Emulsifiers can also impact flavor. They do so by not only adding undesirable flavor elements when misused, but they can modify (good or bad) the contribution of the fat they emulsify.
Proteins that are highly soluble, of high molecular weight or of high concentration can bind volatile components of flavors resulting in changes that again, may or may not be acceptable.
Corn syrup, bulking agents and stabilizers are often added to ice cream mix to provide body (i.e., chew) and a smooth texture; however, these ingredients can affect flavor delivery in the finished product by muting or otherwise modifying flavor quality. Not using these types of ingredients has consequences too. Weak body and/or coarse (icy) texture can negatively impact flavor release in the finished product.
Non-ingredients such as ice crystals and air (overrun) can also impact flavor perception by modifying how the ice cream eats and warms during consumption and releases both taste and aroma components of flavor.
is also need to consider the type of flavor. What works well for non-acid
flavors may not work adequately for fruit flavors. Finally, don't forget
the need for the base mix to be compatible with the flavor and physical
needs of particulate and non-particulate inclusions.
