Oat-based peanut butter-flavored compositions and methods
The present disclosure relates to oat-based peanut butter-flavored compositions and methods of making such compositions. In particular, a method is disclosed of roasting substantially intact groats until CIELAB L*-value change per minute, and CIELAB b*-value change per minute achieve a negative slope to produce roasted oats having a peanut butter flavor. Compositions including roasted oats having a peanut butter flavor are also disclosed.
1. A method of producing roasted oats, the method comprising roasting a plurality of substantially intact groats at a temperature of at least 350° F. to about 600° F. for a time of at least 10 minutes to achieve a negative slope in CIELAB L*-value change per minute, and a negative slope in CIELAB b*-value change minute, where slopes for L*-value change per minute and b*-value change per minute are based on CIELAB measurements at intervals of 5 minutes.
2. The method of claim 1 , wherein the substantially intact groats are roasted for at least 15 minutes.
3. The method of claim 1 , wherein CIELAB a*-value change per minute has a positive slope based on CIELAB measurements at intervals of 5 minutes.
4. The method of claim 1 , further comprising a step of inactivating lipase activity in the plurality of substantially intact groats prior to roasting.
5. The method of claim 4 , wherein the inactivating step includes exposing the plurality of substantially intact groats to steam for sufficient time to inactivate lipase activity.
6. The method of claim 4 , wherein inactivating step includes soaking the plurality of substantially intact groats in water or an aqueous solution at a temperature and pressure sufficient to inactivate lipase activity.
7. The method of claim 4 , further comprising a step of drying the plurality of substantially intact groats to a moisture content of less than 15% after the inactivation step and prior to roasting.
8. The method of claim 7 , further comprising storing the plurality of substantially intact groats following the drying step and prior to roasting.
9. The method of claim 1 , wherein the roasted oats have a moisture content of 6% or less.
10. The method of claim 9 , wherein the roasted oats have a moisture content of 1% or less.
