Interference of natural extract from Jatobá (Hymenaea martiana Hayne) with the physico-chemical characteristics and yield of goat milk and cheese

Summary: | ABSTRACT Several studies have assessed the therapeutic potential of natural products against mastitis, but only a few have evaluated the impacts of this alternative therapy on the main properties of milk and dairy products. In this study, we observed how the treatment of mastitis with ethanolic extract of Jatobá (Hymenaea martiana Hayne) influenced the physicochemical and sensory characteristics of coalho cheese. An ointment containing the ethanolic extract was prepared for intramammary use in six dairy goats. The experiment was conducted in three experimental moments. Milking was performed, manually, and both milk and cheese were subjected to physicochemical and sensory tests. No difference was observed (p>0.05) in the physicochemical aspects of milk between the studied groups. The solids-non-fat showed a statistical difference between experimental moments M1 and M2. The protein means varied from 3.33 to 3.62, and there was a statistical difference between the two moments, while the lactose means varied from 4.79 to 5.38%. The physicochemical aspects of cheese remained similar with both treatments. Except for appearance, the sensory characteristics showed no statistical difference. In conclusion, the use of Jatobá extract ointment did not influence the physicochemical and sensory characteristics of goat milk or cheese.
RESUMO A mastite representa uma das principais enfermidades nos rebanhos de caprinos leiteiros, com implicações na produção de leite e na qualidade final dos derivados. Objetivou-se observar a influência do tratamento da mastite com o extrato etanólico da Hymenaea martiana Hayne sobre as características físico-químicas e sensoriais do queijo tipo coalho. Uma pomada contendo extrato foi elaborada para uso intramamário em seis fêmeas caprinas especializadas na produção de leite. As metades esquerdas dos tetos das cabras receberam essa infusão, enquanto a metade direita era controle. O experimento foi conduzido em três momentos experimentais. Realizou-se ordenha manual e análise físico-química do leite. Para o queijo, foram realizados testes físico-químicos e teste sensorial. Quantos aos aspectos físico-químicos do leite, é possível afirmar que não houve diferença (P>0,05) entre os grupos. Houve diferença estatística para sólidos não gordurosos nos momentos experimentais M1 e M2. As médias de proteína variaram entre 3,33 e 3,62, e houve diferença estatística em dois momentos. As médias de lactose variaram entre 4,79% e 5,38%. Os aspectos físic |
