The invention discloses a
kelp-flavored food ingredient and a preparation method thereof. The preparation method comprises the following steps: firstly, degrading effective ingredients of
kelp by composite enzymes; secondly, fermenting
kelp enzymolysis products by
corynebacterium glutamicum and
pediococcus pentosaceus mixed
bacteria; thirdly, further degrading the effective ingredients of the kelp and releasing secondary metabolites with functionality; fourthly, carrying
drying or
spray drying on fermented products to obtain a kelp food with rich kelp
flavor, easily absorbed nutrients,
antioxidant activity and
antibacterial activity, so that the added value of a product is increased. According to the preparation method, a conventional
deep processing process of the kelp is broken through, a composite
enzymatic hydrolysis process is organically combined with a
food grade microorganism fermentation process, the shortcomings of low
utilization rate, unremarkable product
flavor, non-effective utilization of the nutrients, poor functionality and the like in the conventional
deep processing process of the kelp are overcome, the application range of the kelp product is remarkably expanded, and the economic value of the kelp product is remarkably increased.
