The present study evaluated the effect of two thermal concentration systems on bioactive compounds, the sugar content of tomato (Solanum lycopersicum L.) pulp, and the carotenoid bioaccessibility of pulp concentrate. The closed processing system ensured a higher retention of phenolic and carotenoid compounds. The bioaccessibility of lycopene in tomato pulp concentrate was relatively low (0.54 %) but higher than in raw tomato pulp (0.15 %), corroborating other results that have reported the low availability of the compound in these matrices. Carotenoid extraction from tomato residue was also evaluated through both conventional (CE) and ultrasound (UAE) extractions together with the stability of extracts over 30 days. UAE promoted a superior release of lycopene and lutein than conventional extraction. Lycopene showed less stability with a reduction of 18 % in 30 days. Keywords: phenolic compounds, bioaccessibility, ultrasound, conventional extraction |

The advantages of no-tillage (NT) over conventional tillage (CT) systems in improving soil quality are generally accepted, resulting from benefits in soil physical, chemical and biological properties. However, most evaluations have only considered surface soil layers (maximum 0?30 cm depth), and values have not been corrected to account for changes in soil bulk density. The objective of this study was to estimate a more realistic contribution of the NT to soil fertility, by evaluating C- and N-related soil parameters at the 0?60 cm depth in a 20-year experiment established on an oxisol in southern Brazil, with a soybean (summer)/wheat (winter) crop succession under NT and CT. At full flowering of the soybean crop, soil samples were collected at depths of 0?5, 5?10, 10?20, 20?30, 30?40, 40?50 and 50?60 cm. For the overall 0?60 cm layer, correcting the values for soil bulk density, NT significantly increased the stocks of C (18%) and N (16%) and microbial biomass C (35%) and N (23%) (MB-C and -N) in comparison to CT. Microbial basal respiration and microbial quotient (qMic) were also significantly increased under NT. When compared with CT, NT resulted in gains of 0.8 Mg C ha?1 yr?1 (67% of which was in the 0?30 cm layer) and 70 kg N ha?1 yr?1 (73% in the 0?30 cm layer). In the 0?5-cm layer, MB-C was 82% higher with NT than with CT; in addition, the 0?30 cm layer accumulated 70% of the MB-C with NT, and 58% with CT. In comparison to CT, the NT system resulted in total inputs of microbial C and N estimated at 38 kg C ha?1 yr?1 and 1.5 kg N ha?1 yr?1, respectively. Apparently, N was the key nutrient limiting C and N stocks, and since adoption of NT resulted in a significant increase of N in soils which were deficient in N, efforts should be focused on increasing N inputs on NT systems.
