Avaliação físico-química do leite de cabra cru proveniente de mini-usinas da região do Cariri Paraibano.

Abstract

The goat breeding has been developing in recent years in the world including Brazil, the Northeast region has 90% of the national herd. The identification and characterization of components of goat milk serve as a starting point for developing and implementing programs to improve the quality of milk and its derivatives, thus allowing for increased productivity and supply of safe food to the population. The regions of cariri in Paraiba state have a higher calling for economic and goat rearing and is seen as an efficient and profitable business. The family-based dairy goat has been developed extensively in the region, because along with the climate, productivity is also due to the work of associations and cooperatives of milk producers of the state. Within the context presented, considering the increased production of goat milk in the Northeast and its importance for this region, especially in the state of Paraiba, this study aims to evaluate the physico-chemical properties of raw goat milk from mini-plants located in cariri region to verify whether they conform to Normative Instruction number 37 for goat milk in 2000. In this study it was evaluated the physico-chemical properties of seven mini-mills located in cariri region. The physical and chemical analysis were used: determination of acidity in degrees Dornic, Density at 15 º C, cryoscopic index, fat content, solids nonfat (SNF) and total solids (TS) and fat and protein. With a total of 105 samples analyzed and the resulting values, could be concluded that the acidity of A and C mini-mills were out of default, but the density parameter, all mini-mills were in, in freezing point, the mini-plants A, D, E and F had values outside the legislation, but in the parameter of fatty, all had values within. In the parameter of ESD, all mini-mills were within the established standard, except the mini-mill D, but in the EST parameter, all mini-mills were within the recommended legislation. The parameter of protein of all mini-mills had reached values within the current legislation, except the mini-mill A and D. In all samples, the parameters that showed percentages in non-compliance with the legislation were the acidity with 36.19%, 38.09% with the freezing point, density with 22.85%, 18.09% with ESD and protein to 15.23%. However, the values are considered good because most are embedded in current legislation, showing that the raw goat milk produced in Cariri paraibano is adequated with the physical chemistry.
