Parâmetros de qualidade do leite de cabra armazenado sob frio

Abstract: ABSTRACT:The small-scale goat milk production requires its storage, and such operation is allowed by Brazilian laws. This study aimed at evaluating the cooling and freezing effects on physical-chemical and microbiological characteristics of goat milk. However, no variability was verified in average acidity, alcohol stability, density, fat protein, total solids and lactose values after cold storage. Heat instability was not observed in any of the analyzed samples. There was a decreasing tendency in the somatic … Show more

“…Although PAs possess weak acid characteristics with a pH ranging from 2Á3 to 3Á0 (Campos 2007), it is not possible to confirm any interference in the acidity observed in the milk samples from the animals tested in the study. The reported acidity likely occurred due to the production of lactic acid from lactose consumed by bacteria present in the mammary gland (Morão et al 2018), and these bacteria were likely lactic acid and coliform bacteria (Dutra et al 2014).…”

“…The chemical parameter for lactose was below the standard of the NI 37 (Brasil 2000) in all treatments, suggesting that PA from M. tenuiflora and PA from E. urograndis did not interfere with the lactose index present in the goat milk samples. These observed indices may be due to the micro-organisms that thrive and multiply in the mammary gland (S a et al 2018), as some of these bacteria use lactose as a substrate, thus explaining the significant difference between the lactose index for distilled water treatment compared to that observed after treatment with PA from E. urograndis (Dutra et al 2014).…”

“…No Brasil os registros de teores de gordura no leite caprino têm variado de 3,25 a 4,38% (Dutra, 2014). Na presente pesquisa o teor de gordura obtido no leite in natura foi de 4,17%, mostrando-se dentro da média obtida pela literatura.…”

“…Os valores encontrados na pesquisa para proteína do leite corroboram com os encontrados por Salvador et al (2016), trabalhando com cabras Alpinas e Canárias na Venezuela, porém diferem dos encontrados por Silva et al (2015) no nordeste brasileiro; Câmara et al (2015) em Teresina no Piauí e Pinheiro et al (2014) no período seco em Mossoró -RN que em suas pesquisas, citam valores médio para a proteína do leite variando entre 2,5 e 3,0 %, mesmo estando dentro do estabelecido pela legislação são inferiores aos encontrados neste estudo. Os baixos percentuais foram atribuídos às altas temperaturas ambientais em que os animais se encontravam, que podem reduzir esta percentagem nas estações mais quentes, tendo em vista que a proteína do leite pode sofrer influência da raça, estágio de lactação, época do ano e da sanidade do animal (DUTRA et al, 2014).…”

“…Os teores de lactose variam pouco entre raças, sendo este um nutriente estável na composição química do leite, e os valores da presente pesquisa foram similares aos relados por Madureira et al (2017), Salvador et al (2016), Câmara et al (2015) e Dutra et al (2014) no entanto os valores foram inferiores ao citado por Silva et al (2015), justificado pela alimentação dos animais, com altos teores de concentrados.…”
