| The effect of an edible film obtained from a commercial Aloe vera extract, on the quality maintenance of minimally processed grapes belonging to three different cultivars (Sugar One, Victoria and Black Magic) was evaluated by enzymatic (PPO, PME, β-GAL), physicochemical (pH, acidity, °Brix), and sensorial methods. All the analyzed parameters were measured in extracts obtained from minimally processed grapes packaged in ordinary atmosphere and stored at 4 °C for 15 days. Samples dipped into Aloe vera showed significant differences (p≤0.05) compared to untreated ones. The determination of such parameters and the evaluation of consumer acceptability were helpful to determine the effectiveness of the post-harvest treatment with Aloe vera for a storage period... |

| The survival of six probiotic wild strains of Lactobacillus rhamnosus was compared with that of a type strain during 78 days of storage at 25 and 5 ºC in peach synthetic medium (PSM) and commercial peach jam (PJ). Changes in viable cell counts, pH values, sugar content, and colour parameters were monitored. All strains exhibited better performances in PJ than in PSM, showing count values higher than 7 Log cfu g-1 up to 78 days of storage at 5 ºC. Almost all wild strains remained above the critical value of 6 Log cfu g-1 in samples stored at 25 ºC up to 45 days, while the Lb. rhamnosus GG type strain, used as control, was not able to survive later than 15 days. In the synthetic medium used, the strains showed better survival in the samples incubated at 25... |
