The effects of five novel winemaking technologies on color were evaluated. Cold soak maceration (CSM), dry ice maceration (DIM), prefermentative juice runoff (PJR), delestage (D), and extended maceration (EM) were the process assayed on grapes from Tempranillo variety cultivated in a warm climate zone. Enological and color parameters were determined at stemmed-crushed, pressed, bottled and after 4 months aged in bottle. Significant differences were found in color intensity, percentage of red and blue, and hue at each step of the process and for every technique when compared to the control wine. However, differences tended to decrease with aging. Eleven anthocyanins (glucosides and acylated) were identified, and five quantified by HPLC. Also the anthocyanin distribution in free anthocyanin (% FA), copigmented anthocyanin (% CA) and polimerizated anthocyanin (% PA) were studied. Differences were found for total anhocyanin content, not in their relative abundance. Winemaking processes affected wine's main sensory attributes. DIM achieved a remarkably high valuation for aspect at bottle time, while EM obtained very positive remarks with regards to aroma and persistence at aging DIM and PJR seemed to be the most promising techniques, but after 4-months aging in bottle only EM wine showed a high anthocyanin content.

Resveratrol, is a polyphenol that can be extracted from grapes and red wine, possess potential anti-inflammatory effects, which would result in the reduction of cytokine production, the alteration of the expression of adhesion molecule molecules, and the inhibition of neutrophil function. Resveratrol might also act as an antioxidant, anti-aging, and control of cell cycle and apoptosis. Resveratrol has been shown to have protective effects for patients in shock-like states. Such protective phenomenon is reported to be implicated in a variety of intracellular signaling pathways including the regulation of the mitogen-activated protein kinases (MAPK)/ hemeoxygenase-1 (HO-1) pathway, activates estrogen receptor (ER), and the mediation of pro-inflammatory cytokines, reactive oxygen species (ROS) formation and reactive. Moreover, through anti-inflammatory effects and antioxidant properties, the resveratrol is believed to maintain organ function following trauma-hemorrhage.Key words: resveratrol, anti-inflammatory, trauma-hemorrhage.
