MATTIUZ, Ben-Hur et al. Seedless table grapes minimally processed. Rev. Bras. Frutic. [online]. 2004, vol.26, n.2, pp.226-229. ISSN 1806-9967.  https://doi.org/10.1590/S0100-29452004000200011.

This work evaluated the qualitative aspects of apirenic table grapes (seedless), cv. BRS Morena and Selection 8, when minimally processed and cold stored. Fruits were immersed in a solution of sodium hypochlorite (300 mg Cl.L-1) for 5 min. and stored at 12ºC for 12 hours. Trained personnel using adequate protection and disinfected equipment, removed the berries and rinsed them with chlorinated water (20 mg.L-1). Berries were packaged in transparent polyethylene terephthalate containers and stored at 2.5 ± 1ºC, and 88% RH for 36 days. The loss of fresh mass, development of appearance and color, and contents of total soluble solids (TSS) and titratable acidy (TA) were done. Products of 'BRS Morena' and Selection 8 showed low percentage of accumulated loss of fresh mass (0.16 %). The berries of cultivar BRS Morena were darker (L = 25.04) and purpler colored ( = 332.88) than the Selection 8 (L = 29.86 and = 345.11), bringing a product with better visual quality. Juice of 'BRS Morena' had high content of TSS (22.17 °Brix) and low of TA (0.56 %), that resulted in a ratio (39.76) better and bigger than the Selection 8 (18.81). Products from cv. BRS Morena presented good appearance and commercial quality for 33 days at 2.5ºC that was better than Selection 8 (24 days).
