“…Wet milling is often used for extracting starch, which involves multiple steps including milling or steeping seeds in chemicals, fiber separation, starch suspension in water, centrifugation, purification, dehydration and drying. [ 4,5 ] It is reasonable to assume that larger molecules and/or molecules containing longer chains will be harder to extract, and/or more easily degraded during the extraction process. This is because more monomer groups mean a greater chance that one will be degraded, and it has been shown that shear scission, for example, during milling, causes molecular degradation [ 6 ] of longer chains.…”

Obtaining relations between starch genetics/environment, its molecular structure, and its properties requires that the extraction of starch does not extract more small than large molecules and does minimal damage to molecular structure. There is no single study examining a range of techniques with more than one starch type and with clearly defined criteria for optimal extraction. Here two very different substrates are considered: rice and chickpeas. Eight different techniques are used, and the criteria for optimal extraction are that there should be the greatest number of longer chains (quantified by the average size of the debranched starch) and of larger molecules (quantified by the average size of the whole-undebranchedmolecules), these being the most susceptible to degradation and loss during extraction. Size-exclusion chromatography is used to obtain the requisite structural data. The optimal method of extraction from rice is found by using 0.45% sodium metabisulfite at 4°C for 0.5 h with protease addition, while that for chickpea starch extraction is by using 0.45% sodium bisulfite for 6 h and washing the starch repeatedly with water. The methodology for determining optimal methods can be readily used for other starch sources.

“…It has been used by oleochemical, cosmetic, biofuel, and food industries (PAIVA, 2013;VINHAL;LIMA;BARBOSA, 2014). The other parts of the babassu fruit (epicarp, mesocarp and endocarp) have considerable potential for coal, tar, fuel, gas, starch, and alcohol production (CASTRO; CASTILHO;FREIRE, 2016;CINELLI et al, 2014;MANIGLIA;TAPIA-BLÁCIDO, 2016;TEIXEIRA, 2008TEIXEIRA, ., 2014.…”

Neste trabalho, a nova abordagem para obter extrativos, hemicelulose e lignina total a partir de típicos resíduos de biomassa brasileira é otimizada pela Metodologia de Superfície de Resposta (MSR). Os efeitos das variáveis reacionais, incluindo o tempo de reação e extração das hidrólises, assim como a razão molar do substrato álcool foram investigados. Foram usados modelos de regressão polinomiais quadráticos para analisar os dados experimentais. O coeficiente de determinação foi maior do que 0,85 e o modelo foi considerado adequado. Os dados obtidos demonstraram que as metodologias do Laboratório Nacional de Energia Renovável devem ser adequadas para cada tipo de biomassa. Além disso, com os resultados otimizados, estes dados podem ser empregados na produção de larga escala de combustíveis oriundos de biomassa.

“…Around 7% of the fruit total weight is kernel, so the Babassu kernel oil yield is low. 20,21 The Babassu palm petiole from its leaves is an attractive raw material for activated carbon production since it is a renewable and highly sustainable material not to mention its easy obtention and at a low cost which can not only add economic value to it but help in income generation and environment preservation.…”

carbons (ACs) with well-developed microstructure and high microporosity were obtained from biomass by potassium hydroxide activation. The preparation process consisted in producing carbon materials in the ratios of activating agent to raw material 70:30, 50:50, 30:70 and 25:75 (w/w) characterized by thermal analysis coupled to spectroscopy (TG-DTA / FT-IR), scanning electron microscopy (SEM), N 2 adsorption isotherms at -196 °C and activation isotherm at 500 and 600 °C for 3.0 h. Specific surface areas (SBET) within 728 and 1712 m 2 g -1 and (S mic ) within 1054 and 1923 m 2 g -1 were obtained, while the micropores surface area was calculated using the Dubinin-Astakhov (DA) equation and the pore size distribution calculated from density functional theory (DFT) was found to be in the range 1.09 -1.77 nm. Adsorption isotherms were fitted using Langmuir and Freundlich non-linear models and the adsorption capacity determined for methylene blue dye was between 27.13 and 459.20 mg g -1 .
