The flavor droplets become encapsulated by the gum. Instead, a flavor emulsion is a microscopic dispersion of tiny flavor droplets in an aqueous medium, usually water. This is made possible by the use of an emulsifying agent, commonly a natural vegetable gum such as Xanthan or Acacia. Emulsions are made through a high-shearing process where drops of flavor are mixed with an emulsifier shearing is the process of making tiny droplets. EmulsionsĪn emulsion avoids the use of solvents, such as alcohol, to blend the flavors into a liquid solution. are typically in a base of mostly alcohol and water, but the specific contents and ratios are not standardized and can vary widely by manufacturer. Other extract flavors such as almond, lemon, orange, etc. must contain at least 13.35 ounces of vanilla beans per gallon during extraction and be in a solution of at least 35% alcohol. Vanilla extract is the only flavor of extract that is regulated in the United States by the Food and Drug Administration (FDA). According to the FDA, any product labeled as “pure” vanilla extract and sold in the U.S. One benefit of extracts is that they generally contain enough alcohol to prevent spoilage from microorganisms or bacterial growth. When shipping extracts, caution is required as most are considered hazardous due to their lower flash points and flammability. The alcohol used is generally tasteless, but it can have a distinct alcoholic smell. Alcohol is a common base for blending essences as most flavors are easily soluble in alcohol. Some flavors, like vanilla, are made by percolating chopped vanilla beans with an alcohol solvent. ExtractsĮxtracts are the most common type – found in grocery stores everywhere. The concentrated flavor essences and aromatics may be of natural or artificial origin, but the primary difference is the type of base the flavor is diluted in and how the flavor is kept in solution. At a rudimentary level extracts and emulsions have one thing in common: aroma and flavor. Both deliver on flavor, but let’s explore the differences in more detail. The coated vanilla butter creams may be eaten after another 24 hours.Flavors are available in a wide variety of formats and two of the most common types for baking are “the extract” and “the emulsion”. Keep at room temperature (65 to 75 degrees F) for 4 to 24 hours. Roll each piece and place on waxed paper. Cut the tube with a butter knife into bite size pieces. Take small sections of the batch and roll it into a 1-inch diameter tube. Dip hands into flour and knead batch until it is soft and creamy. Pour batch onto a table (previously sprinkled with flour). Continue mixing until batch becomes semi-firm. When the sugar mixture reaches 110 degrees F, start the mixer on slow speed and add the flour and butter. If sugar crystals form on top of the batch as it is cooling, sprinkle the sugar crystals lightly with water to dissolve. Pour the cooked batch into a mixing bowl and let it cool to 110 degrees F. At 235 degrees F wash down the side of the pan with a brush soaked in water to remove sugar crystals.
