“…Lower concentrations of ethanol (10.7-11.4 %) in musts supplemented with diammonium phosphate and 10.8 % for the control trials, were obtained by Mendes-Ferreira et al (45) in the fermentation of honey must (37g: 100 mL) by S. cerevisiae UCD522 at 22 °C for 25 days. Amorim et al (7) reported that at the optimum point in the fermentation of honey must supplemented with acerola, 120.1 g/L (15.2 %) of ethanol was obtained.…”

Research background. Due to the lack of nitrogen in honey, the fermentation may be limited or delayed, in addition to stimulating the production of unpleasant sensory compounds, such as sulfur derivatives. The use of natural supplements has been investigated as low-cost alternatives for mainly correcting the nutritional deficiency of nitrogen in honey must in mead production. Experimental approach. Initially, the physicochemical characterization of the extracts was carried out. The fermentative performance of three yeasts [Saccharomyces bayanus Premier Blanc (SbPB), Saccharomyces cerevisiae Montrachet (ScM) and Saccharomyces cerevisiae Safbrew T-58 (ScST58)] in honey musts supplemented with rice bran (RBE) and soybean meal (SME) extracts was evaluated. The trials were compared with the fermentations of musts with commercial supplement (CS) and the control trials. Fermentations were carried out in Erlenmeyer flasks containing honey must supplemented with RBE, SME and CS (30 g/L), inoculated with 106 cells/mL and incubated at 30 °C for 264 h. Results and conclusions. There was significant difference in the evaluated properties of the extracts, with the exception of reducing sugars. The fermentations with SME reached the highest cell concentrations, as well as the largest sugar consumption of glucose and fructose and ethanol. The glycerol concentrations slightly increased when SME and CS were used. The largest concentrations of succinic and acetic acids were registered in the control trials produced by SbPB, ScM and ScST58. There was no production of formic and lactic acids. Results showed that the extracts can be used as low-cost alternatives for correcting the nutritional deficiency of nitrogen in honey must since they presented results similar to the synthetic supplement. Novelty and scientific contribution. The use of low-cost, unconventional supplements such as those used in this work, in addition to reducing the cost of the process by reducing fermentation time by providing nutrients needed to improve yeast metabolism, prevents the formation of compounds undesirable in the beverage due to prolonged fermentation time. It also makes it possible to add value to industrial by-products. Unconventional supplements have still been little tested in mead production.

“…O processo produtivo do hidromel torna-se dispendioso devido ao tempo prolongado do processo fermentativo acarretado pela alta concentração de açúcares e às baixas concentrações de proteínas e minerais do mel (RAMALHOSA et al, 2011;ARAÚJO et al, 2020a). Para solucionar este problema, vários trabalhos têm sido desenvolvidos a fim de otimizar o processo fermentativo, e o uso de suplementos tem sido uma das estratégias utilizadas para reduzir o tempo do processo fermentativo (AMORIM et al, 2018, ARAÚJO et al, 2020b.…”

O presente trabalho teve como objetivo realizar o estudo de viabilidade econômica de uma microindústria produtora de hidromel suplementado com polpa de siriguela e extrato de farelo de soja, instalada no município de Ribeira do Pombal, BA. Para o desenvolvimento do estudo, realizaram-se pesquisas de levantamento, bibliográfica e experimental, obtendo-se dados importantes para elaboração do fluxo de caixa: custos fixos e variáveis, investimento, depreciação, juros, lucro tributável, imposto de renda, fluxo líquido, amortização e bônus de adimplência. Aplicaram-se também os métodos de avaliação de investimento [valor presente líquido (VPL), taxa interna de retorno (TIR) e o método do payback]. O investimento do projeto para produção mensal de 2250 L de hidromel foi de R$ 305.419,84, resultando nos seguintes indicadores econômicos: VPL (R$5.861,03), TIR (23%), payback simples (2 anos) e payback descontado (3 anos), considerando-se a taxa mínima de atratividade de 15% e uma vida útil de 10 anos. Logo, o empreendimento foi considerado economicamente viável, além de ser uma possibilidade para geração de renda para agricultores familiares.

The medicinal plant Jatropha curcas exerts beneficial effects against ethanol toxicity in humans. In this work, we investigated the protective effect of three extracts (ethanol [Et], vegetal glycerin [VG], and propylene glycol [PG]) of J. curcas leafs against Et‐induced damage in human peripheral blood mononuclear cells. The cytotoxicity of the extracts alone or in combination with each other in mononuclear cells was also assessed. A thermodynamic and kinetic analysis of the protection assumed that the cells were in a metastable equilibrium of growth and death, and the mass action of the extracts was used to determine the optimal concentration for each extract. The PG and VG extracts were cytotoxic, with an efficiency index of protection (η) of approximately −20% and −41%, respectively. By contrast, η values of ∼220% were observed for Et extracts (0.625% vol/vol) and combined extracts (Et + PG) at concentrations of (0.375 + 0.250)% and (0.5 + 0.5)%, respectively. These results identify J. curcas as a promising source of bioactive compounds and show that appropriate modeling can provide a powerful system for determining the optimal conditions for drug action.
