“…15 The diet with the addition of increasing cottonseed levels leads to an increase in the intake of unsaturated fatty acids (UFA) in cows, as observed in Table S2 (SI section), where it is possible to verify that the increase in the percentage of cottonseed in the formulations caused an increase in their UFA values. Lipid supplementation for lactating cows causes changes in milk composition, depending on the milk source and level.…”

The objective of this study was to evaluate the effect of whole cottonseed on diets of cows under grazing on fatty acid profile and milk cholesterol. Five crossbred Holstein × Zebu cows were distributed in a 5 × 5 Latin square. Inclusion levels were 0, 6, 12, 18 and 24%. There was a linear decrease in all fatty acids quantified, saturated and monounsaturated (p > 0.05), possibly due to the action of polyunsaturated fatty acids ingested in the diet. There was no influence of treatment on conjugated linoleic acids or cholesterol. It is concluded that, regardless of inclusion level, there is a modification in the milk lipid profile, reducing the concentration of saturated fatty acid, monounsaturated fatty acid, and making it rich in polyunsaturated fatty acids, which are beneficial to health.

“…The degree of unsaturation is considered one of the most important factors in the characterization of saturated and unsaturated fatty acids. Gondim-Tomaz et al (2016) pointed out that saturated fatty acids, such as palmitic acid, are more stable to oxidation than unsaturated fatty acids.…”

“…In addition, it has been identified as a raw material for biodiesel production, given its high energy value, low sulphur content and acidity (Naureen et al, 2015). Oil that has a higher concentration of oleic acid and a lower linoleic content is more suitable for biodiesel production, due to the higher oxidative stability conferred by such a composition (Gondim-Tomaz et al, 2016). By contrast, the fatty acid balance in standard sunflower oil shows a preponderance of linoleic acid instead of oleic acid, which makes it more sensitive to oxidation.…”

It has been suggested that fatty acid balance in standard sunflower oil may be influenced by the genotype of the plant or by variation in environmental growth conditions. Therefore, this study analysed aspects of sunflower productivity and oil quality obtained from achenes of plants cultivated in a semi-arid environment, resulting from seed obtained from other regions with different edaphoclimatic characteristics. The experiment was conducted between February and May, in a Brazilian semi-arid area. At 90 days after sowing (DAS), the physiological maturation period, tissue was harvested, and the yield of plant green matter, oil and oil per hectare was evaluated. A comparative analysis of the oil content of achenes before and after planting (parental v progeny) was performed. The experiment was conducted in a randomized block design of 4 treatments (genotypes), Embrapa122, BRSG01, Helio253 and Helio250, and 4 replications, for a total of 16 experimental plots, with each plot constituting 8 plants. In this study, sunflowers were produced in the climatic conditions of the Brazilian semi-arid region with biomasses, achenes and oil contents that were different from other crop productions in the country, providing the possibility of obtaining oil with a distinct chemical composition.

A verticalização do subproduto de óleo bruto de algodão poderá ser a meta de algumas empresas algodoeiras que dispõem, além das máquinas de descaroçamento e de prensa hidráulica para o enfardamento de fibra, de uma unidade de extração de óleo, mas que necessita agregar ao seu circuito produtivo agroindustrial os processos de refino para a produção de óleo comestível. Portanto, este trabalho tem por objetivo mostrar vias que possam aperfeiçoar os procedimentos de preparação das sementes de algodão, extração do óleo das amêndoas e refinamento de óleo, destacando em cada etapa dos processos envolvidos entre a chegada do algodão em rama na agroindústria até a saída dos produtos finais. Para se obter sucesso em tal empreendimento é necessário melhorar o marketing do produto (óleo refinado) pelo fato da semente de algodão possui características proteicas adequadas, que possibilita o seu uso na indústria alimentícia. Além disso, essa agregação de valor do óleo bruto de algodão irá depender da aquisição de alguns equipamentos requeridos nos processos de seu refinamento e também da qualidade inicial da semente, quando é recém-colhida e com umidade em torno de 10%, determinam a obtenção de um bom óleo.
