“…It has been reported that during the commercial production of pineapple juice around 20-40% of wastes are generated by FPP and FPC (Khedkar et al 2017). This percentage is similar to the one obtained in this research and has led to research for which these wastes are used as substrates in fermentative and hydrolytic processes to obtain bioactive compounds (Kaprasob et al 2017 reported that 96% of the total pineapple wastes correspond to organic material and 4% to inorganic, which potentiates its use in bioprocesses.…”

“…The residues generated during the processing of the fresh peel of the pineapple (FPP), Fresh core of the pineapple (FCP), and crown represent between 45 and 65% of the total weight of the fruit; about 76% of this waste is fibre, 99.2% is the insoluble fraction, and 0.8% is the soluble fraction (Selani et al 2014). These residues have been used in several ways (Difonzo et al 2018) including the use of pineapple wastes as substrates to obtain bioactive compounds such as biopolymers (Vega-Castro et al, 2016), polyphenols (Sepúlveda et al, 2018), biohydrogen, biogas, and alcohols such as ethanol or butanol (Khedkar et al, 2017), which have the potential for industrial application. Among the evaluated residues, the pineapple peel is outstanding due to the high concentration of reducing sugars (97 g L À1 ) obtained through the application of acid hydrolysis as a pre-treatment (Vega-Castro et al 2016).…”

“…In the bioprocessing industry, there is interest in the use of residual materials due to their easy accessibility and the C and N 2 content, necessary elements in fermentation processes (Neethu et al 2015); however, the greatest interest is the possibility of reducing the costs associated with the substrate, given that these constitute between 60 and 70% of the total cost of the process (Khedkar et al 2017).…”

Gold honey variety pineapple wastes and sacha inchi sub-products (SIS) were characterized in their elemental, physical, and chemical form in order to formulate a supplemented fermentation substrate (SFS) for the growth Weissella cibaria. The peels and fresh cores of the pineapple (FPP, FPC) were dried and ground (PPP, PPC) and then mixed (MCPP). The following procedures were then undertaken: a physicochemical characterization (moisture, a w , pH, acidity, and soluble solids) of the SIS, FPP, FPC, PPP, and PPC; a proximal characterization of he FPP, FPC, SIS, and SFS; and an elemental analysis (C-N 2-H 2-O 2-S) of the MCPP, SIS, and W. cibaria, which allowed the stoichiometric equation to be defined and the SFS to be formulated. We then evaluated the effect that homogenization and heating to boiling point had on the concentration of reducing sugars in the SFS (g L À1). Finally, W. cibarias kinetic fermentation parameters were evaluated in the SFS and in a commercial substrate (control). The results showed FPP and FPC yields of 26.02 AE 0.58 and 14.69 AE 1.13%, respectively; a higher total sugar content in FPC (7.21%) than in FPP (6.65%); a high crude protein content in SIS (56.70%), and a C:N 2 ratio of 6.50:1.00. Moreover, the highest concentration of reducing sugars (4.44 AE 0.29 g L À1) in the SFS was obtained with 5 h of hydrolysis under homogenization pre-treatments and heating until boiling. The SFS allowed the adaptation of W. cibaria, and there was a biomass production of 2.93 g L À1 and a viability of 9.88 log CFU mL À1. The formulation of an unconventional fermentation substrate from-Agro-industrial wastes of pineapple and sacha inchi to produce valuable products (such as lactic acid biomass through fermentation), is an excellent perspective for large-scale application.

The hydrolytic action of Aspergillus niger and Trichoderma reesei commercial cellulases, alone or combined with A. niger hemicellulase, against industrial pineapple waste as a previous step to produce bioethanol was investigated. Methods Enzymatic hydrolysis experiments were conducted in static conditions in an incubation oven, by adding the corresponding enzyme mixture to the pineapple waste (combinations of 0, 0.1, 0.2 and 0.4 (w/w) of cellulase from A. niger or T. reesei and hemicellulase from A. niger). pH and total soluble solids were examined along the treatments, and the sugar profile in the final hydrolysates was evaluated by High-Performance Anion-Exchange Chromatography. Results T. reesei cellulase exhibited a significantly faster initial hydrolysing rate than A. niger cellulase (0.258±0.004 vs. 0.15±0.07, for the maximum enzyme concentrations assayed), although differences regarding soluble sugars increments were not significant at the end of the treatment (0.349±0.009 vs. 0.34±0.05). Glucose, fructose, sucrose, arabinose, xylose and cellobiose were identified in the hydrolysates. Increasing enzyme concentration (cellulase or hemicellulase) produced an increase in total and fermentable sugars released (17 and 11%, respectively, for the maximum enzymatic concentration assayed); besides, a synergistic effect of combining hemicellulase and cellulase was identified. Accumulation of cellobiose (up to 4.4 g/L), which may slow down hydrolysis, evidenced the weaker β-glucosidase activity of T. reesei cellulase. Due to its performance and the lower cost of the enzyme, A. niger cellulase was chosen as an alternative. Conclusions 2 Commercial A. niger cellulase represents an efficient alternative to T. reesei cellulase for the saccharification of industrial pineapple waste, especially when combined with a hemicellulase. Total sugars present in the final hydrolysates indicated that A. niger cellulase performed similarly at a lower cost, with no cellobiose accumulation. However, if processing time is a limiting factor, Trichoderma reesei cellulase could be the one preferred.

“…Estudos tem sido realizados para a aplicação de subprodutos industriais do abacaxi como as cascas, utilizadas na produção de bolos ricos em fibras (MARTIN et al, 2012), em hambúrgueres bovinos enriquecidos com subprodutos de abacaxi como substitutos de gorduras , na fermentação e produção de biobutanol (KHEDKAR et al, 2017) e a farinha das cascas que podem ser empregadas na produção de barras de cerais (DAMASCENO et al, 2016). Com isso, torna-se necessário garantir que o consumo dos subprodutos seja seguro antes de aplicá-los em qualquer produto alimentício.…”
