Phenolic Characterisation and Antioxidant Capacity of Young Wines Made From Different Grape Varieties Grown in Helanshan Donglu Wine Zone (China)

Abstract

The Helanshan Donglu wine zone (China) is one of the most successful wine region of China, and the phenolic characterisation and antioxidant capacity of the primarily young, monovarietal wines from there were evaluated. The result showed that Helanshan Donglu wines contained abundant phenolic compounds, especially flavan-3-ols, and possessed high antioxidant capacity. In different grape varieties, the phenolic profiles varied greatly in both red and white wines. For red wines, Cabernet Sauvignon represented the highest total phenols (2 631 mg/L GAE), total flavonoids (1 840.83 mg/L CTE) and antioxidant capacity. Gamay and Cabernet Gernischt possessed the highest total flavan-3-ols (1 108.08 mg/L CTE) and total anthocyanins (258.78 mg/L CGE). Amongst the white wines, Chardonnay and Chenin blanc showed the highest phenolic contents and antioxidant capacity. (+)-Catechin and (-)-epicatechin were dominant phenolic constituents in both the red and white wines. Gallic acid and salicylic acid were the second most abundant in red wines, while gentisic acid was the second most abundant in white wines.

“…The Folin-Ciocalteu method with some modification was used for the determination of the TP content (Li et al, 2014;Ma et al, 2013Ma et al, , 2014. Briefly, 1 ml of sample, 60 ml distilled water, and 5 ml Folin-Ciocalteu reagent were added in a 100 ml volumetric flask successively.…”

Profiles of Phenolic Acids and Flavan‐3‐ols for Select Chinese Red Wines: A Comparison and Differentiation According to Geographic Origin and Grape Variety

“…Additionally, this region is new and had been rapidly developed in recent years. The wineries were established in recent years and the management was similar (Ma and others ; Sun and others ). By contrast, the Huaizhuo Basin Region had a more complicated terrain with more microclimates (Sun and others ).…”

“…Additionally, the use of geographical designations allows wine producers to obtain market recognition and often a premium price (Romina and others ). Monovarietal wines, which are popular globally, also allow wine producers to obtain a premium price (Ma and others ). Because of these factors, wine has been extensively investigated to determine potential frauds such as adulteration of the wine and false declarations of the geographical origin, grape variety, and age (Romina and others ).…”

“…Traditionally, the production and consumption areas of wines were western countries (Ma and others ; Sun and others ). In recent years, wine has grown popular in China.…”

“…Phenolic compounds are one of the main components of wine. Based on the chemical construction, these constituents can be divided into 2 groups: flavonoid compounds and nonflavonoid compounds (Ma and others ). Additionally, based on the contribution to wine color, these constituents can be divided into 2 groups: colored phenolic compounds and noncolored phenolic compounds (Li and others ).…”
