This study evaluated the effect of the processing and long-term storage on the antioxidant potential and activity of antioxidant enzymes of frozen purées from six acerola clones. Ripe acerolas from clones BRS 235, BRS 236, BRS 237, BRS 238, II47/1 and BRS 152 were harvested; the pulp was processed, packed in sealed polyethylene plastic bags and stored in a domestic freezer at -18°C for 11 months. Samples of each clone were analyzed on harvest/processing day and every 30 days after for bioactive antioxidant compounds, antioxidant enzyme activity and total antioxidant activity. Acerola purées presented a decrease of non-enzyme antioxidants and an increase of antioxidant enzymes activities, indicatives of a compensatory mechanism between enzymatic and non-enzymatic antioxidants. In acerola purée, anthocyanin and polyphenols are strongly correlated to soluble solids content and vitamin C seems a major contributor to total antioxidant activity. Clone II47/1 had an outstanding performance regarding the antioxidant potential of its purée and the best storage period at -18ºC would be 150 days, for all clones studied.

The nutritional value and the content of bioactive compounds in potato tubers are influenced by many soil, climate and agrotechnical factors. This study investigated the effect of drip irrigation and nitrogen fertilization by broadcasting and fertigation on the content of dry matter, starch, monosaccharides, total sugars, vitamin C, polyphenolic compounds, chlorogenic acid and antioxidant activity in tubers of “Augusta” potatoes. Additionally, the magnitude of the changes in the tested components during their long-term storage (6 months) was also assessed. Drip irrigation had a significant positive effect on the content of dry matter, starch, vitamin C, monosaccharides, sucrose, total sugars, total polyphenols, chlorogenic acid and antioxidant capacity. Compared to broadcasting fertilization, fertigation significantly increased the content of vitamin C, total polyphenols and chlorogenic acid, as well as the antioxidant activity of potato tubers. Long-term storage contributed to a decrease in the tested components. The exception was the content of monosaccharides, where a more than twofold increase was noted, especially in the case of irrigated tubers. The results of the research showed a beneficial effect of drip irrigation and fertigation on the content of bioactive compounds and the nutritional value of “Augusta” potato tubers.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
