Abstract:

Noni (Morinda citrifolia L.) is rich in polyphenols, flavonoids, terpenoids, and iridoids. However, its bad taste and smell make noni fruit unsuitable for consumption. After fermentation, noni wine becomes free from the undesirable smell. Nevertheless, it is still unclear whether processed noni could retain its original nutrients and effects. Therefore, we conducted a series of evaluations on the nutritional composition and efficacy of noni wine. Our results showed that the polyphenol, flavonoid, and vitamin C contents in noni wine were 558.80, 234.42, and 0.30 mg/L, respectively. Our animal experiments showed that 40 ml kg daynoni wine could reduce bodyweight, as well as the levels of body fat, serum triglycerides, total cholesterol, and low-density lipoprotein, while it simultaneously increased the amount of energy expenditure and activity, and improved the systemic antioxidant capacity in mice following a high-fat diet. The results of the gene expression and western blot analyses showed that 40 ml kg daynoni wine could regulate the Nrf2 pathway and improve the antioxidant enzyme gene expression in mice maintained on a high-fat diet, thereby improving body lipid metabolism, reducing fatty acid synthesis, and promoting fatty acidβ-oxidation. Our study indicated that drinking 40 ml kg daynoni wine could effectively prevent high-fat diet-induced oxidative stress and obesity in mice. PRACTICAL APPLICATIONS: Noni fruit is rich in nutrients but its bad smell and hardship of processing make its commercialization difficult. Previous studies mainly focused on fresh noni juice and its primary processed products, while few noni products, of poor taste and low quality, are available in the market. Therefore, the fruit wine with both the nutritive values and the special flavor of noni has broad market prospects. Our work provides a valuable reference for the commercialization of noni wine.
