The invention relates to the technical field of food byproduct
processing, in particular to a production process of a yellow
wine vinasse flavor extract. The method comprises the following steps: firstly, performing soaking,
fermentation, aging and
solid-liquid separation on the yellow
wine vinasse to obtain
vinasse mud, adding grafted
amylose into the vinasse mud for pre-soaking, and then adding grafted
amylopectin for ultrasonic-high-pressure homogenization circulation treatment to obtain the superfine vinasse mud. Finally,
propylene glycol and medium-chain
triglyceride are used for constructing a temperature-resistant
solvent, double grafted
starch is supplemented for emulsification and homogenization, and the
flavor extract is prepared. According to the method, a step-by-step synergistic extraction-double
grafting embedding-
oil phase heat barrier
system is constructed, the problems that the
utilization rate of vinasse
flavor substance raw materials is insufficient and volatilization loss occurs under high-temperature
processing are effectively solved, the obtained product is fine and smooth in texture, rich in flavor and excellent in
heat resistance, and the application value of vinasse by-products is greatly improved.
