“…In the materials evaluated, according Table 2, it could be observed how the pineapple peel and oyster mushroom flours presented significantly lower values of CD. This is in accordance with the nature of their carbohydrates, which are composed mainly of soluble and insoluble fibre and low content of starch (Ruangviriyachai et al., 2010; Synytsya et al., 2009) and also for their high ash content. Table 3 shows a significant ( p < 0.05) positive correlation ( r = 0.722) between the variables of pH and CD, which can be explained by the accumulation of minerals due to chelation and the presence of acids in fibrous and porous materials (Hajar et al., 2012).…”

The physicochemical, compositional and functional properties of flour from green plantains (Musa acuminata) of the large green plantain variety, oyster mushrooms (Pleorotus ostreatus), pineapple peel (Ananas comosus) of the 'apple pineapple' variety, yellow peas (Pisum sativum), chickpeas (Cicer arietinum), whole grain rice (Oryza sativa), whole grain corn (Zea mays) and whole grain white quinoa (Chenopodium quinoa) were evaluated by using one-way analysis of variance, Pearson correlations and principal component analysis chemical composition of the eight flours, statistically differed (p < 0.05). Oyster mushroom and yellow pea flours had the greatest protein content (28.92 and 21.02%, respectively), whereas the pineapple peel, peas and corn stood out for their high contents of Fe and Zn. All flours exhibited emulsifying and foaming activities, while hydration and interfacial properties showed statistically significant negative correlations. There was a clear relationship between levels of protein and carbohydrates and gelation and syneresis phenomena in thermally treated flour suspensions. According to principal component analysis of functional, physicochemical and compositional properties, flours were classified into five groups of raw materials: (1) yellow peas, (2) chickpeas, rice, corn and quinoa, (3) green plantain, (4) pineapple peel and (5) oyster mushrooms. Results are promising to formulate mixes and composite flours for fortification and/or enrichment of food products by using different technological processes.

“…Additional technique, immobilized cell technique, managed to yield 11.63 g/L ethanol by S. cerevisiae, and 1.66 g/L ethanol by E. aerogenes under the same fermentation period. It is even rarer to find research on bioethanol production from pineapple leaf; most of the works took rotten pineapple juice as the feedstock in bioethanol production (Domínguez-Bocanegra et al, 2014;Nigam, 1999;Ruangviriyachai et al, 2010;Tanaka et al, 1999). However, this paper does not present the potential bioethanol production estimation from pineapple juice waste since there is no known specific pineapple juice waste generation annual data in Malaysia.…”

“…In the field of ethanol production from lignocellulosic biomass, industrial pineapple waste is particularly interesting as pineapple is the third most abundantly traded fruit worldwide and its waste represents about 50% (W/W) of the total processed fruit [ 8 ]. In addition, its waste contains high amounts fermentable sugars and potentially hydrolysable cellulose and hemicellulose [ 9 , 10 , 11 ].…”

Electrochemical impedance spectroscopy (EIS) has been used for monitoring the enzymatic pineapple waste hydrolysis process. The system employed consists of a device called Advanced Voltammetry, Impedance Spectroscopy & Potentiometry Analyzer (AVISPA) equipped with a specific software application and a stainless steel double needle electrode. EIS measurements were conducted at different saccharification time intervals: 0, 0.75, 1.5, 6, 12 and 24 h. Partial least squares (PLS) were used to model the relationship between the EIS measurements and the sugar determination by HPAEC-PAD. On the other hand, artificial neural networks: (multilayer feed forward architecture with quick propagation training algorithm and logistic-type transfer functions) gave the best results as predictive models for glucose, fructose, sucrose and total sugars. Coefficients of determination (R2) and root mean square errors of prediction (RMSEP) were determined as R2 > 0.944 and RMSEP < 1.782 for PLS and R2 > 0.973 and RMSEP < 0.486 for artificial neural networks (ANNs), respectively. Therefore, a combination of both an EIS-based technique and ANN models is suggested as a promising alternative to the traditional laboratory techniques for monitoring the pineapple waste saccharification step.
