Introduction. Consumption of unripe grape juice (verjuice) has been portrayed by the traditional belief, as a means of combating dyslipidemia. We aimed to evaluate the effects of unripe grape juice consumption on lipid profile in healthy human volunteers. Methods. We asked 42 enrolled volunteers to drink 10 cc of verjuice within 30 minutes to 2 hours after lunch and 10 cc of it after dinner. After taking 120 doses of verjuice, another fasting lipid profile was obtained from each participant. The statistical analysis was performed by SPSS 13 software. Results. After analysis of the data, the mean ± standard deviation for all the variables was obtained. Among those improvement of HDL-C was significant after the trial (P value < 0.001). TG, TC, and LDL improvement were not significant. Conclusion. Our study declared that verjuice has a dramatic effect on improving HDL-C level of serum but no any other lipid improvement effect was obtained.

The development of green aquaculture practices has led to the supplementation of fish diets with natural immunostimulants such as organic acids. This study aimed to assess the dietary effects of verjuice (VJ; unfermented unripe grapes; Vitis vinifera) on hematological parameters, skin mucosal immunity, transcriptional immune responses, and antibacterial serum activity against Aeromonas hydrophila in rainbow trout. The fish (51.

Cabernet Sauvignon from the California Paso Robles AVA was processed with a contrasting array of cap management frequencies, consisting of punch-down (PD) frequencies (0, 1, 2, and 3 PD/day) over two vintages, one of which the fruit was harvested at two contrasting maturity levels. Wines followed with up to 3 years of bottle aging for basic and phenolic chemistry, and the wines of the second harvest of 2020 were submitted to sensory analysis. There were almost non-existent effects due to the frequency of punch downs on parameters such as ethanol, pH, titratable acidity, lactic acid, and glucose + fructose.

The wine sector is working to add value, enhance sustainability and reduce waste, yet often creating new products with unknown consumer acceptance. Verjuice, juice made from discarded unripe thinned grapes, is an example. Whilst verjuice has various culinary uses, its versatility in beverages continues to expand.

The food sector's interest in sustainability and the demand for novel bioactive compounds are increasing. Many fruits are wasted every year before ripening due to various climatic conditions and harsh weather. Unripe mangoes, grapes, and black lemons could be rich sources of phenolic compounds that need to be fully elucidated.

Low acid is the main defect in the northwest wine region of China in recent years. The fermentation of unripe grape (UG) and wine grapes with low acid contents was carried out. Compared with control group (CK), the addition of UG addressed the core flaw that low acid grape bring to wine firstly, it significantly increased titratable acid, tartaric acid and malic acid while significantly decreasing alcohol and volatile acids in wine.
