“…Regarding molds and yeasts, counts lower than those observed in this study (3.9-4.8 log cfu/ml) were reported by Kunitake et al (2013), who obtained values in the range of 2.5-3.9 log cfu/ml. Note: Means (n = 3) followed by the same lower case exponent in the same column (comparison among trials) and by the same upper case exponent in the same row (comparison between raw and pasteurized juice) are not different (p > .05).…”

“…The processing, however, did not have a significant effect on this parameter. Similar results (0.047%-0.052% of citric acid) were found byKunitake et al (2013), while other studies presented slightly higher values for acidity Kayalvizhi et al (2016). reported acidity of 0.2% citric acid in fresh cane juice, andChauhan et al (2002) observed acidity in the range of 0.24%-0.39% for the juice extracted from different cultivars Saxena et al (2016).…”

“…The tested levels of temperature were [78 (− α ), 80 (−1), 85 (0), 90 (+1), and 92 (+ α )]°C. As for the holding time, the studied levels were [16 (− α ), 20 (−1), 30 (0), 40 (+1), and 44 (+ α )] s. The levels of t and T were set based on studies conducted by Andrade, Matos, Rocheto, Valadao, and Petrus (2014), Kunitake et al (2013), and Silva et al (2016). The features of the heat exchanger available to perform this research work were also considered.…”

Sugarcane juice is a commodity in tropical countries as it provides health benefits; it is a nutritious, inexpensive, and refreshing drink, which helps keep the body healthy. However, the development of suitable preservation technologies is imperative to enhance its shelf life (Kaavya, Pandiselvam, Kothakota, Priya, & Prasath, 2019). Cane juice contains 80% water on average; its soluble solids content may range from 15 to 25 °Brix, pH between 5.0 and 6.0, titratable acidity between 0.04 and 0.12 (% citric acid) and water activity 0.99. The climate, soil, cultivar, and maturity of the raw material significantly affects the physicochemical properties of juice (Bomdespacho, da Silva, Lapa-Guimaraes, Ditchfield, & Petrus, 2018). The juice fermentation starts rapidly after extraction (Qudsieh, Yusof, Osman, & Rahman, 2002). Due to spoilage-causing microorganisms and enzymatic reactions, the fresh juice develops a brown color and tastes sour within a few hours after extraction when not stored appropriately (Yusof, Shian, & Osman, 2000). Many attempts have been made in the overall stabilization of sugarcane juice, and pasteurization may successfully be used in this product's preservation. Notwithstanding, to the best of our knowledge, no study addressing the optimization of time × temperature binomial has been reported. Knowledge of these parameters is crucial to the emerging cane juice processing industry. Mao, Xu, and Que (2007) stated that the development of effective treatment procedures that preserve the fresh quality of cane juice would allow it to be more widely marketed and also enhance

“…Both values were lower than that determined in this work (65%). Kunitake et al (2013) reported a wide variation in soluble solids content (15.2 -23.6 ºBrix) and titratable acidity (0.038 -0.071 g citric acid 100 mL -1 ) in freshly extracted juice from the same cultivar (SP 813250) and growth site.…”

“…Depending on the intended shelf life to meet specific consumer market demand, the storage of the cane juice at 8 °C (74 day-shelf life) may be more strategic than storage at 4 °C (94 day-shelf life) in terms of cost saving. Kunitake et al (2013) studied the effect of pasteurization temperature on the shelf life of passion fruit pulp-added cane juice stored at 7 °C. The juice´s shelf lives treated at 85, 90 and 95 °C 30 s -1 were 31, 39 and 52 days, respectively.…”

The shelf life of standardized sugarcane juice stored under refrigeration

The shelf life (SL) of freshly extracted sugarcane juice is limited to a few hours, and the use of hurdle technology is a strategy to ensure its safety and stability. The SL of standardized cane juice (19.4 °Brix, 0.085% acidity and pH 4.35), pasteurized at 95 °C/30 s and stored under refrigeration, was estimated. Odeal (4 °C), commercial (8 °C) and abusive (12 °C) conditions were tested. Microbiological and sensory assays were carried out on the newly processed juice (time zero) and overtime to estimate the SL. Counts of psychrotrophic bacteria and molds and yeasts equivalent to 4 and 3 logCFU mL-1 , respectively, were set as acceptable maximum levels to establish the SL. Average scores greater than 5 (in the 9-point hedonic scale) and percentages of approval greater than 60% were both used as threshold values for juice´s appearance and flavor. The juice´s SL stored at 4, 8 and 12 °C were 94, 74 and 26 days, respectively. The combination of multiple technologies applied in this study was effective in obtaining a product with high sensory acceptance and a SL compatible with possible demands of the consumer market.
