MATTIUZ, Ben-Hur; MIGUEL, Ana Carolina Almeida; GALATI, Vanessa Cury  e  NACHTIGAL, Jair Costa. Effect of stored temperature in minimally processed seedless table grapes. Rev. Bras. Frutic. [online]. 2009, vol.31, n.1, pp.44-52. ISSN 1806-9967.  https://doi.org/10.1590/S0100-29452009000100008.

The objective of this research was to evaluate the postharvest quality of three apirenic (seedless) table grapes cultivars submitted to minimally processed and stored under refrigeration and room temperature. It was used the cultivars BRS Clara, BRS Linda and BRS Morena produced at Embrapa Grapes and Wine/Tropical Viticulture of Experimental Station, in Jales, state of São Paulo. The clusters were immersed in a solution of sodium hypochlorite (200 mg Cl.L-1) for 5 minutes before being stored at 12ºC for 12 hours. The berries were removed and rinsed with alcohol solution (70%) per 5 seconds. After drained the water excess, the berries were conditioned in 500 mL capacity trays of transparent tereftalato of polyethylene (PET) with lid. Each unit with 200 g of berries was stored at 12±1.8ºC and 24±0.8ºC during 12 days. Every three days, the loss of weight, appearance, color, soluble solids (SS) and titratable acidity (TA) were evaluated. The temperature of 12ºC kept the turgidity, the color, the ratio SS:TA and the marketing conditions of the berries from the three cultivars tested after nine days of evaluations. The berries stored at room temperature (24ºC), loss the commercial quality at the third day for BRS Clara and BRS Linda cultivars and at the sixth day for the BRS Morena cultivar.
