Resumo - O objetivo principal deste trabalho foi avaliar o efeito da pasteurização lenta (65°C 30min-1) em banho-maria e do congelamento (-18°C), seguido de estocagem por uma semana (-18°C), sobre as características microbiológicas e físico-químicas do leite de cabra pré-embalado. Quinze amostras individuais de leite de cabra foram analisadas antes e após o processamento, realizado no próprio capril. A pasteurização lenta mostrou-se eficaz na redução da contaminação por mesófilos, psicrotróficos e fungos, mas a baixa contagem de coliformes fecais e totais do leite cru não proporcionou a mesma eficácia neste grupo de bactérias. O armazenamento do leite congelado durante uma semana não alterou a sua qualidade microbiológica. Não se observou influência significativa do processamento térmico sobre as concentrações dos principais constituintes do leite ou sobre as propriedades físico-químicas analisadas. Os resultados obtidos nesse experimento mostraram também que um equipamento de leitura infra-vermelha calibrado com leite bovino pode ser usado para a determinação dos teores de gordura e proteína.
Microbiological and physical-chemical characteristics of goat milk after low temperature time pasteurization and freezing.
Abstract - The aim of this trial was to evaluate the effect of water bath low temperature long time pasteurization (65°C 30 min-1) and freezing (-18°C) followed by one-week storage (-18°C) on the physical-chemical characteristics of goat milk. Fifteen individual milk samples were analyzed before and after being processed by the producer himself. Thermal processing applied was efficient for reducing mesophilic, psychrotrophic, molds and yeasts contamination, even though the low total and fecal coliform counts in raw milk did not allow the same statement considering that bacteria group. Thermal processing had no significant influence on the main constituents' concentrations or on the analyzed physical-chemical properties. The results obtained in this study also showed that infrared equipment calibrated with cow milk could be used for fat and protein determinations in goat milk.

Limited funding is a major barrier to implementing ambitious global restoration commitments, so reducing restoration costs is essential to upscale restoration. The lack of rigorous analyses about the major components and drivers of restoration costs limit the development of alternatives to reduce costs and the selection of the most cost-effective methods to achieve restoration goals. We conducted detailed restoration cost assessments for the three most widespread biomes in Brazil (Amazon, Cerrado, and Atlantic Forest) and estimated the restoration costs associated with implementing Brazil?s National Plan for Native Vegetation Recovery (12M hectares). Most surveys (60?90%) reported using the costly methods of planting seedlings or sowing seeds throughout the site, regardless of the biome. Natural regeneration and assisted regeneration approaches were an order of magnitude cheaper but were reported in < 15% of projects. The vast majority of tree planting and direct seeding costs were incurred during the implementation phase, and nearly 80% of projects ended maintenance within 30 months. We estimated a price tag of US$0.7-1.2 billion per year until 2030 to implement Brazil?s restoration plan depending on the area that recovers through natural regeneration. Our results offer valuable insights for developing strategies to make restoration cheaper and to increase its cost-effectiveness for achieving diverse benefits in Brazilian ecosystems. Our survey also provides a starting point for sound assessments of restoration costs and their drivers in other biomes, which are needed to reduce the financial barriers to scaling up restoration at a global scale.
