Actinidin (EC 3.4.22.14), a thiol cysteine protease unique to Actinidia species, hydrolyzes dietary proteins at broad cleavage sites spanning hydrophobic and basic amino acid residues, thereby accelerating gastric and small-intestinal proteolysis, increasing chyme fluidity, and enhancing nutrient bioavailability. The high concentration of ascorbic acid (vitamin C) and polyphenolic compounds—including quercetin, catechins, and caffeic acid derivatives—scavenge reactive oxygen species via direct electron donation, upregulate endogenous antioxidant enzymes (superoxide dismutase, glutathione peroxidase), and inhibit NF-κB–mediated pro-inflammatory cytokine transcription. Soluble dietary fiber, particularly pectic polysaccharides, increases fecal bulk and water retention while serving as a substrate for colonic fermentation to short-chain fatty acids (butyrate, propionate), which nourish colonocytes and promote motility. Additionally, bioactive polyphenols and omega-3 fatty acid precursors in kiwifruit extract inhibit platelet aggregation by suppressing thromboxane A₂ synthesis and COX-1 activity, as reviewed by Duttaroy (2024, PMID 39519549), contributing to cardiovascular protection.

Current evidence for kiwifruit extract is primarily based on in vitro studies rather than human clinical trials. Laboratory studies demonstrate measurable antioxidant activity using Folin-Ciocalteu assays with total phenolic content expressed as gallic acid equivalents per gram dry weight. Platelet aggregation inhibition studies show kiwi peel extract provides strongest anti-thrombotic effects, while lectin hemagglutination assays used 1300 µg protein extract in controlled conditions.
