The objective of this study was to evaluate the chemical and oxidative stability of dried macaúba (Acrocomia totai) fruit in different air conditions and stored for up to 120 days. The macaúba fruits were collected, sanitized, dried at the temperatures of 40, 50, 60 and 70 °C and stored in raffia bags at room temperature. Drying at higher temperatures resulted in pulps with a darker and orangish color and pulp oil with lower titratable acidity contents and acidity indices. Throughout storage, there was an increase in the acidity index of pulp oil and a reduction in the ascorbic acid and carotenoid contents in the pulp. Drying and storage reduced the ascorbic acid and carotenoid contents of the pulp. Drying at lower temperatures results in pulps with a higher free-radical sequestering ability. Pulp oil quality was compromised by drying and storage time. Newly harvested macaúba fruits can be dried at 40, 50, 60 or 70 °C and stored for up to 120 days without compromising nut oil quality.

Abstract The search for sustainable agri-food systems is increasing. This study aims to identify the main initiatives of agroextractivism in the state of Mato de Grosso do Sul (Cerrado and the Pantanal biomes), their products, market/consumption perspectives, and the panorama of the institutional environment. Native species with processing and marketing conducted through family initiatives were selected. The relevant aspects of public policies and market potential analyses were based on a literature review. The use of 15 native species present in 12 communities demonstrates the potential of food systems with the recognition of indigenous peoples, quilombolas, traditional communities, and family farming. Sociobiodiversity products value their origin and social, environmental, and economic functions, and can conquer new sustainable markets, including international ones.

Resumo É crescente a busca por sistemas agroalimentares mais sustentáveis. Este trabalho visa indicar as principais iniciativas do agroextrativismo no estado de Mato de Grosso do Sul - biomas Cerrado e Pantanal - seus produtos, as perspectivas de mercado/consumo e o panorama do ambiente institucional. Foram escolhidas espécies nativas que possuem processamento e comercialização realizados por iniciativas familiares. Aspectos relevantes das políticas públicas e análise do potencial de mercado foram baseados em revisão bibliográfica. O aproveitamento de 15 espécies nativas presentes em 12 comunidades, demonstram o potencial dos sistemas alimentares, com reconhecimento dos povos indígenas, quilombolas, comunidades tradicionais e da agricultura familiar. Os produtos da sociobiodiversidade valorizam sua origem e suas funções sociais, ambientais e econômicas, podendo conquistar novos mercados sustentáveis, inclusive os internacionais.
