solid material that were induced by the oxidative conditions. Addition of agents such as ascorbic acid and sulfur dioxide can act to counter these compositional changes ( Shahidi and Naczk, 1995 ). An optimum concentration of phenolics in cider apple
toxicological impact. Acidification potential refers to the ability of certain substances to buildup and release hydrogen ions, thus acidifying that environment. For example, air pollutants such as sulfur dioxide and N 2 O interact with water to form acids and
residues in the aril, and the size, weight, exocarp color, fruit pole strength, fruit volume, total soluble sugars, and sulfur dioxide residues from postharvest treatment are unaffected ( Kanaree and Pankasemsuk, 2005a , 2005b ). Originally discovered as

representation of the samples. Boxes were promptly delivered to the Kearney Agricultural Research and Extension Center in Parlier, CA, for cold storage. The fruit were stored at ≈32 °F and 80% RH for 33 d in 2011 and for 30 d in 2012. Sulfur dioxide generator

treatment was whole-cluster pressed using a hydraulic bladder press (Hydro 40 Inox; Zambelli Enotech, Camisano Vicentino, Italy), up to 2 bars of pressure. Juice was treated with 50 mg·L −1 of sulfur dioxide as potassium metabisulfite for microbial control
and whole-cluster pressed. Resulting musts were immediately treated with 50 mg·L −1 sulfur dioxide and sampled. Samples (200 mL in 2008, 500 mL in 2009) were frozen at −40 °C for later analysis. Glycosides were extracted from juice samples via a solid
sulfur dioxide (SO 2 ). The juice was left to settle for 24 h, and subsequently inoculated with Saccharomyces cerevisiae DV10 (Lallemand, Montreal, Quebec, Canada) and fermented in 5-gal glass carboys at 20 °C (ambient temperature). Yeast nutrients were
corrosive, several growers now use sulfur dioxide (SO 2 ) generators, often referred to as “sulfur burners,” in place of acid injectors for acidifying the irrigation water and reducing soil pH. Elemental sulfur burned in the generators is converted to
