Probiotic yogurt with brazilian red propolis: physicochemical and bioactive properties, stability, and shelf life

This study aimed to evaluate the quality parameters in probiotic yogurt produced with Brazilian red propolis to replace potassium sorbate used in conventional yogurt (CY). Microbiological stability and shelf life, physicochemical properties (pH, acidity, chemical composition, and fatty acids), and bioactive properties (phenolic compounds and antioxidant activity) were evaluated. The addition of red propolis (0.05%) to replace the potassium sorbate did not change the pH, acidity, fatty acid profile, chemical composition, or shelf life. Microbiological stability of at least 28 days was achieved, while a drastic reduction in the lactic acid bacteria content was observed in the CY during refrigeration storage. Phenolic total contents were higher than those of the control, and consequently, yogurt with red propolis showed higher antioxidant activity.We thank the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Brazilian government, for scholarship support (Finance Code 001), the Dr Cátia Ionara Santos Lucas (INSECTA laboratory, UFRB, Cruz das Almas, Brazil), and the technical team of the Polytechnic Institute of Bragança laboratory (Bragança, Portugal) for their support during the research.info:eu-repo/semantics/publishedVersio

How States Make Race: New Evidence from Brazil

The Brazilian state recently adopted unprecedented race-targeted affirmative action in government hiring and university admissions. Scholarship would predict the state's institutionalization of racial categories has "race-making" effects. In this article, we ask whether the Brazilian state's policy turnabout has affected racial subjectivities on the ground, specifically toward mirroring the categories used by the state. To answer, we conceptualize race as multidimensional and leverage two of its dimensions—lay identification and government classification (via open-ended and closed-ended questions, respectively)—to introduce a new metric of state race-making: a comparison of the extent of alignment between lay and government dimensions across time. Logistic regression on large-sample survey data from before the policy turn (1995) and well after its diffusion (2008) reveals an increased use of state categories as respondents' lay identification in the direction of matching respondents' government classification. We conclude that the Brazilian state is making race but not from scratch nor in ways that are fully intended
