Quickly and easily measure the antioxidant capacity of wine. Use it for quality improvement and quality control.
Winemakers may consider alternative technologies to reduce or completely eliminate the use of additives such as sulfur dioxide (SO2), which acts as a preservative against wine oxidation. As a result, the evaluation of the oxidation stability of must and wine is becoming increasingly important. In wine science, methods for measuring antioxidant capacity such as DPPH, FRAP, and ABTS are well known, but the complexity and time required for these methods pose challenges. We have collaborated with the University of Florence to focus on PAT (Plasma Antioxidant Test) as an alternative method and have developed a measurement kit. The measurement kit can quantitatively measure the antioxidant capacity due to polyphenols and tannins in terms of ascorbic acid equivalent (mg/L). The amount of SO2 is not considered. This allows for research on: 1) raw materials, 2) the effects of treatments such as clarification, 3) the influence of containers used for purification (wood, steel, etc.), 4) changes in color as an index of antioxidant capacity, 5) stress from storage and transportation in warehouses, and 6) parameters when placing on shelves (temperature, light), types of closures (cork, synthetic), and types of bottles (clear, dark glass, etc.). The measurement time is 30 minutes.

Starting as an import trading company in 1927, we have been developing our business with many overseas suppliers and domestic customers over the years. Through our services of connecting the two together, Higuchi has become the well trusted "Japan distribution channel" for suppliers, and the "dependable vendor" who provides a stable supply of the latest high-valued overseas products to customers. Today, we conduct not only importing but also exporting businesses, trilateral trades, and overseas business investments as well. We have also expanded to local subsidiaries in the United States and China, to which we are able to effectively network overseas. Higuchi believes in the criticalness of providing a stable supply to customers, and we also place the highest priority on the coexistence with suppliers, to whom we can mutually develop together in a long-term perspective.
