“…The cellulose conversion results are in accordance with literature (Barcelos et al, 2011;Macedo et al, 2011;Carvalho et al, 2013;Idrees et al, 2014). Even working only with cellulases and β-glucosidase enzymes without xylanases or hemicellulase enzyme supplementation, it was possible to produce a high quantity of xylose in the enzymatic hydrolysis using the bagasse subjected to the alkaline pretreatment.…”

-Glucose production from sugarcane bagasse was investigated. Sugarcane bagasse was pretreated by four different methods: combined acid and alkaline, combined hydrothermal and alkaline, alkaline, and peroxide pretreatment. The raw material and the solid fraction of the pretreated bagasse were characterized according to the composition, SEM, X-ray and FTIR analysis. Glucose production after enzymatic hydrolysis of the pretreated bagasse was also evaluated. All these results were used to develop relationships between these parameters to understand better and improve this process. The results showed that the alkaline pretreatment, using sodium hydroxide, was able to reduce the amount of lignin in the sugarcane bagasse, leading to a better performance in glucose production after the pretreatment process and enzymatic hydrolysis. A good xylose production was also observed.

“…The C. brasiliense pulp contains lipids, water, carbohydrates, proteins, and minerals, along with a high fiber content (Table 1) (Macedo et al, 2011;Vera et al, 2007;Lima et al, 2007). Additionally, C. brasiliense pulp is a potential source of potassium (K) (560 mg/100 g), magnesium (Mg) (174 mg/100 g), copper (Cu) (0.9 mg/100 g), and manganese (Mn) (1.4 mg/100 g) and contains zinc (Zn) (2.5 mg/100 g), calcium (Ca) (161 mg/100 g), phosphorus (P) (162 mg/100 g), iron (Fe) (1679 mg/100 g), and nitrogen (N) (1148 mg/100 g) (data expressed on dry basis) (db) (Mariano-da-Silva et al, 2009).…”

Bioactive compounds and functional potential of pequi (<em>Caryocar</em> spp.), a native Brazilian fruit: a review

et al. 2018

View full text Add to dashboard Cite

SUMMARY:Pequi is an indigenous word that means "thorny covering" and is used to describe fruits from the Caryocar spp. These fruits are widely consumed as food and used in traditional medicine by Brazilians in the savannah (Cerrado biome) and the Amazon region. The fruit is rich in lipids, mainly oleic acid, and other bioactive substances including carotenoids, phenolics, and tocopherols. The oil extracted from the pulp or "almond" (seed) has a high local socioeconomic impact and is associated with nutritional and therapeutic benefits. A wide array of health benefits such as antioxidant, anti-inflammatory, antitumor, and antimicrobial effects, improved cardiac function, as well as an increased lymphocyte-dependent immunity have been attributed to the pequi fruit, especially its pulp. This review provides a comprehensive overview on the edible parts of pequi fruits (pulp and almond), more specifically the oil produced from these parts, as a source of functional compounds with biological activity. Moreover, it considers the differences among the three more commercially-important species from the genus Caryocar. KEYWORDS: Bioactive compounds; Caryocaraceae; Fruit; Health benefits; Oleic acid RESUMEN:Compuestos bioactivos y funcionalidad potencial del pequi (Caryocar spp.), fruta nativa brasileña. Revisión. Pequi es una palabra indígena que significa "piel espinosa" y es utilizada para describir los frutos de Caryocar spp. Estos frutos son ampliamente consumidos como alimentos y son utilizados en la medicina popular por los brasileños ubicados en el Savannah (bioma Cerrado) y en la región amazónica. La fruta es rica en grasas, ácido oleico y otros bioactivos, incluyendo carotenoides, fenoles y tocoferoles. El aceite procedente de la pulpa o de la almendra (semilla) tiene un importante impacto socioeconómico local y está asociado con beneficios nutricionales y terapéuticos. Una amplia gama de beneficios para la salud tales como antioxidante, antiinflamatorio, antitumoral, antimicrobiano, mejora de la función cardíaca, así como el aumento de la inmunidad linfocitaria han sido atribuidas a la fruta, especialmente a su pulpa. Esta revisión proporciona una descripción exhaustiva sobre las partes comestibles de la fruta del pequi (pulpa y almendra), más específicamente del aceite producido a partir de estas partes, como una fuente de compuestos funcionales con actividad biológica. Además se consideran las diferencias encontradas entre las tres especies comerciales más importantes del género Caryocar.

“…Glycerol selling represented a minor impact on the total biodiesel production costs when compared with the cost of pequi meal. According to Macedo et al [29], pequi meal is valorized due to its composition, particularly its high starch content, which warrants the evaluation of its potential also as a feedstock for ethanol production. Moreover, the solid residue coming from the fermentation process has a huge potential as a protein source for use in animal feed.…”

This study deals with the economic feasibility of biodiesel production in Brazil by using the pequi oil as raw matter. The software SIMB-E was used during simulations in which a cash flow model related economic indexes with biodiesel production features. Competitiveness between selling prices of biodiesel and petro diesel, fixed capital costs, operating costs, depreciation, and auxiliary costs were also considered during the economic calculations. A total of 8 scenarios of production were simulated and 4 of them presented competitive biodiesel selling prices, being considered as worthwhile projects in the final analysis. But, all simulated scenarios were found to be potentially profitable and should be motivated considering sustainability, social and environmental aspects. The worthwhile projects were plants with alkaline transesterification, indicating that the success of biodiesel production from alternative raw matter still depends on incomes from the feedstock co-products and glycerol, as well as on the costs of catalyst and feedstock. Pequi contributed to the feasibility of biodiesel production due to its high yield, low costs of fruits and good valuation of its co-products.
