EEM data recorded at different pH values was exploited by MCR-ALS in order to determine qualitative information about Brazilian red wines. In addition, the geographical traceability of wines produced in the Serra Gaúcha (Rio Grande do Sul) was carried out by DD-SIMCA considering 53 samples from the target class and 20 from other producing regions. The fluorescence signal corresponds to 9 EEMs recorded at different pH (3?11), generating four-way data. By MCR-ALS decomposition, eight factors were retrieved and related to typical chemical compounds found in red wine. In addition, the EEM pH data was used to build a one-class classification model, considering that MCR scores and all samples of the target class were properly recognised as belonging to the target class, with maximal sensitivity equal to 1. Samples of the non-target class were also adequately rejected by the model, and the specificity was found to be 0.97. |

Conteúdo: |
Fifteen popcorn cultivars grown in Brazil were analysed for expansion power, percent composition, dietary fiber, minerals, vitamins and aminoacids. The mean Expansion Power was 23,1, low for the international standards. The second major component in popcorn is the dietary fiber, ranging from 21 to 29%. Minerals and vitamins are presents in small amounts. Popcorn, like others cereals, is defficient in the limiting aminoacid lysine ans triptophan. The popcorn consuption, without addition of other ingredients, can be used in sodium restricted diets, and is a good source for dietary fiber intake. |
