Resumo: Avaliaram-se iogurtes de leite de cabra contendo ou não Bifidobacterium longum, B. breve, B. pseudolongum ou B. bifidum, adicionados ou não de aroma de morango. Os dados obtidos nas análises higiênico-sanitárias e físico-químicas foram dentro dos valores exigidos pela legislação brasileira; apenas o valor encontrado para lactose esteve abaixo do recomendado. Quanto às bactérias do iogurte, não houve diferença na contagem de Streptococcus salivarius subsp. thermophilus durante a estocagem, e não foi detectado Lactobacillus delbrueckii subsp. bulgaricus nas diluições utilizadas. A enumeração de Bifidobacterium spp. manteve-se entre 106 e 108UFC/mL e não diferiu entre as espécies ao longo do tempo. Considerando-se a adição ou não de aroma, a análise das variáveis tempo e aroma não mostrou diferença estatística. A contagem entre os Bifidobacterium spp. demonstrou que nenhum microrganismo apresentou um comportamento superior a outro. Na análise sensorial, as amostras de iogurtes adicionados ou não de Bifidobacterium spp. e adicionados de aroma de morango não apresentaram diferenças entre si. O estudo mostrou ser possível a elaboração de iogurte de leite de cabra adicionado de Bifidobacterium spp. e de aroma de morango com qualidade assegurada, potencial para uso probiótico e boa aceitação pelo consumidor.

Abstract: Goat milk yogurt with or without Bifidobacterium longum, B. breve, B. pseudolongum, or B. bifidum, and supplemented or not with strawberry aroma were evaluated. Data obtained from hygienic-sanitary and physicochemical analyses were within the values recommended by the Brazilian legislation, except for lactose contents, which were lower than the recommended. In relation to the yogurt bacteria, there was no difference in the counts of Streptococcus salivarius subsp. thermophilus during the storage, and Lactobacillus delbrueckii subsp. bulgaricus was not detected. The counts of Bifidobacterium spp.ranged from 106 to 108CFU/mL, without difference between the species along the time. Considering the addition of flavor or not, the analysis of aroma and time variables showed no statistical difference. The counts of Bifidobacterium spp. demonstrated that none showed a superior value. For the hedonic scale test, there was no difference between yogurts supplemented or not with Bifidobacterium spp., and added or not with strawberry aroma. The study showed to be possible the elaboration of goat milk yogurt supplemented with Bifidobacterium spp. and strawberry aroma, presenting safety, potential for probiotic use, and good acceptability by consumers.

Lowland irrigated rice in southern Brazil is typically grown in monoculture, with one rice crop per year. However, during the past 10 years, some farmers have switched from the traditional continuous rice system to a 2-y soybean-rice rotation. Here we performed an on-farm assessment about the impact of introducing soybean to the lowland continuous rice system in southern Brazil. The goal was to determine how the soybean-rice rotation compared to continuous rice in terms of yield and profit. We used farmer-reported survey data collected from lowland rice-based systems in southern Brazil over three growing seasons. Cropping-system yield, profit, and return-to-inputs were compared between fields following continuous rice versus soybean?rice rotation. In addition to the survey data analysis, we evaluated the long-term economic impact of adopting the rotation using a combination of a crop simulation model and Monte-Carlo stochastic modeling. Average rice yield was 26% higher in the rotation compared to continuous rice. Besides the rotation effect, sowing date, N fertilizer, and weed management explained most of the field-to-field variability in rice yield. Cropping-system yield and gross income were lower in the soybean-rice rotation than in continuous rice as a result of replacing an irrigated crop (rice) by a water-limited rainfed crop (soybean). Despite that yield penalty, there was no difference in net economic return between the two cropping systems due to lower production costs in soybean-rice rotation compared to continuous rice. The rotation also exhibited smaller labor requirement and higher benefit-to-cost ratio and return to labor than continuous rice. Despite these potential benefits, our long-term analysis indicated higher inter-annual variability and economic risk in the rotation compared to continuous rice. Other factors further constrain adoption of the soybean-rice rotation, including the high risk of growing soybean in fields that are prone to excess water and difficulties to change current farm logistics. Findings from this study are relevant to other rice-based systems in the world looking for opportunities to increase or maintain net profit while reducing costs and/or labor.
