Saccharification of pineapple peelings through dilute acid mhydrolysis

Antonio1, Anna Angelica C. Pineapple was initially used up only as a fresh fruit. With the help of the developing technology and promising researches, the fruit is now prepared and consumed in different forms.

Equations 2 - 5 were used to calculate the change in the reactant concentration with time. The method of Kurschner-Hanack [12] was used to analyze for the concentration of cellulose and hemicellulose in the plantain peels. This method is a gravimetric method where the weight of cellulose and hemicellulose is measured when nitric acid and Acetic acid dissolved every other component of the plantain peels; cellulose and hemicellulose are insoluble in water, acetic acid and nitric acid.

The flask is connected to a reflux condenser and heated with a heating mantle for 2 hours. The dried residue is weighed as the cellulose and hemiccellulose content of the sample.

Saccharification of pineapple peelings through dilute acid mhydrolysis

Results and Discussion 3. The values agree closely with the work done by Ighodaro [9]which reported that the cellulose content of ripe plantain peels is Enzymatic Hydrolysis of Plantain Peels 3.

Saccharification of pineapple peelings through dilute acid mhydrolysis

The goodness of fit of the model was checked by the determination coefficient R2. The value of the adjusted determination coefficient Adj. There is a The model equations for hydrolysis in terms of the actual factor with all the terms and without the insignificant terms are given in Equations 8 and 9 respectively.

Optimization study of citrus wastes saccharification by dilute-acid hydrolysis :: BioResources

Deleting the non significant terms, the model equation reduces to: The result of the verification of the optimum numerical solution showed that the optimum solution predicted the real solution closely.

The deviation of the experimental yield of glucose from the predicted yield was only 6. The composition of plantain peels. The graph of the predicted against the actual values shown in Figure 1 also confirmed the closeness of the predicted values and the actual values.

The data points of the optimization runs fall along the diagonal of the squared graph showing the close relationship of the predicted and the actual points. In other words, the quadratic model was adequate for the analysis.

Factors and Interactive Effects on Hydrolysis The contour and 3D graphs of Figures show the factors and the interactive effects on the yield of simple sugar Glucose.

The effect of temperature on the yield of glucose was however significant as confirmed in Table 5. The plot of the predicted values against the actual values for hydrolysis optimization. The contour and 3D plots of time against temperature.

The contour and 3D plots of pH against temperature.Three different fermentation modes, direct fermentation, separate hydrolysis and fermentation, and simultaneous saccharification and fermentation of the biomass were tested and compared.

The results show that the main sugars obtained from pineapple waste were: glucose, uronic acid, xylose, galactose, arabinose and mannose. Pineapple Peel Hydrolysis by T.

viride Crude Extract Passion fruit peel was treated with 1 M NaOH, autoclaved at °C for 30 min and washed with distilled water. The pH was then neutralized with dilute phosphoric acid and the mixture was dried at 70 °C [ 30 ]. hydrolysis using dilute H 2SO4 was found to give higher yields of TRS and PS from fruit wastes in shorter times.

Bioethanol Production from Pineapple (Ananas ...

However, the enzymatic hydrolysis was found to be a better choice for the production of bioethanol from the BP and pineapple peels by through co-culture of A. niger and S. cerevisiae [3]. In this study dilute acid. The effect of time, acid concentration, temperature and solid concentration on dilute-acid hydrolysis of orange peels was investigated.

A central composite rotatable experimental design (CCRD) was applied to study the individual effects of these hydrolysis factors and also their interdependence effects. This study entitled “Saccharification of Pineapple Ananas comosus peelings through Dilute Acid Hydrolysis” was show more content A clear aqueous solution of carbohydrates to be analyzed is placed in a test tube, then phenol and sulfuric acid are solution turns a yellow- orange color as a result of the interaction between the carbohydrates and phenol.
