Mentha spicata liquid flavoring agent and production method thereof

The present invention discloses a mentha spicata liquid flavoring agent. The mentha spicata liquid flavoring agent mainly consists of mentha spicata, soy sauce, sugar, ethanol and caramel pigment, and is prepared by mentha spicata pre-treating, washing, blanching, rinsing and draining, drying, crushing, extracting and blending steps. Through single factor test and orthogonal test of process parameters and orthogonal test of a blending ratio of the liquid flavoring agent, the impact of blanching temperature, blanching time, extracting time, extracting temperature, a mixing ratio of mentha spicata and soy sauce, the blending proportion and other factors on the quality of the mentha spicata liquid flavoring agent are studied to fully develop mentha spicata resources, and to conduct deep processing on the mentha spicata. The produced mentha spicata liquid flavoring agent is dark red brown in color, lucidus and high in transparency; rich and strong in fragrance, outstanding in unique mentha spicata fragrance and free of peculiar smell; and outstanding in palatable taste, strong in aftertaste, and capable of meeting consumer demands for flavoring and health protection.
