Development of a polyphenol‐enriched whole kiwifruit dietary supplement and its potential in ameliorating hyperlipidemia

Kiwifruit pomace, which contains abundant phenolic compounds, is typically discarded during the juicing process, leading to wastage of valuable resources. To address this issue, various indicators (including total acidity, sugar/acid ratio, vitamin C, total polyphenols, polyphenol monomers, and soluble solids content) of 15 kiwifruit cultivars were evaluated and juiced. Then, a polyphenol-concentrated solution from kiwifruit pomace was backfilled into kiwi juice to prepare whole nutritious compound kiwi juice, and its anti-hyperlipidemic activity on obese model mice was then investigated.
