The invention discloses a
processing method of functional brown
sugar rich in polyphenols. The
processing method comprises following steps: sugarcane is juiced so as to obtain a
raw material liquid,
lime milk is added, and an obtained mixture is heated so as to obtain a heated
raw material solution; a first-grade
ceramic membrane is used for filtering so as to obtain a first grade membrane clear juice and a first grade membrane condensed juice; a second membrane is used for filtering so as to obtain a second membrane grade clear juice and a polyphenols-enriched second grade membrane condensed juice; and the polyphenols-enriched second grade membrane condensed juice is used for producing the functional brown
sugar rich in polyphenols, wherein at least one or a plurality of ingredients selected from
colla corii asini, red date, longan,
Angelica sinensis, Radix
Codonopsis, Chinese wolfberry, bulbus lilii, herba leonuri, and ginger are taken as functional ingredients, and are decocted with water so as to obtain a solution, or dried and smashed into
powder, the polyphenols-enriched second grade membrane condensed juice is subjected to
evaporation concentration and is mixed with the solution or the
powder, and
sugar boiling, graining, moulding, and packaging are carried out so as to obtain the functional brown sugar rich in polyphenols. According to the
processing method, effective enrichment of polyphenols is realized, a plurality of functional ingredients which can be taken as both
medicine and food are added, the content of polyphenols is 4 to 8 times higher than that of brown sugar obtained via traditional technology, and brown sugar quality and
nutrient value are improved.
