“…They utilized pineapple waste for the production of methane using semicontinuous anaerobic digestion which could produce up to 1682 ml/day of biogas with methane content of 51% in maximum. Rani and Nand (2004) reported that different conditions of pineapple peels gave biogas yields ranging from 0.41-0.67mg/kg volatile solids with methane content of 41-65%.…”

“…Its production in large quantities results in serious waste disposal problem which can lead to environmental pollution, if not utilized (Rani and Nand, 2004). Finding use, especially on a large scale, for this abundant waste material would therefore be profitable from both an environmental and economic point of view.…”

“…The peel is rich in cellulose, hemicelluloses and other carbohydrates. It has a substrate potential generation of methane by anaerobic digestion and currently has limited use as animal, poultry and fish feeds (Rani and Nand, 2004;Paengkoum et al, 2013).…”

Cellulases are major group of enzymes with wide-ranging industrial and biotechnological applications. The high cost of cellulase production is a major factor limiting its industrial applications in cellulose bioconversions, hence the need to develop low-cost production systems for this enzyme. Cellulose-rich plant biomass which may be agricultural or industrial in origin exists abundantly as organic wastes which are detrimental to the environment. This study evaluated cellulase production by Penicillium citrinum isolated from deteriorating orange fruits, using brewer's spent grain and pineapple peels as cheap, alternate substrates. Cellulase titres 3.82 ± 0.136 U/mL and 1.405 ± 0.151 U/mL were produced by the fungus, using pineapple peels and brewer's spent grain as substrates, respectively, under submerged fermentation. Maximum cellulase production by P. citrinum occurred with the use of pineapple peels as substrate, after 72 h fermentation period, with the use of pineapple peels at a concentration of 1.5% w / v and peptone as the best nitrogen source. The optima pH and temperature for the production of cellulase by the fungus was found to be 6.0 and 50 o C, respectively. Findings from this study indicated the potential use of pineapple peels as cheaper, alternative substrate for the production of cellulase thus mitigating its hazardous effect on the environment as pollutant. P. citrinum was able to grow and produce good levels of cellulase using solely pineapple peels as low-cost substrate, at high temperature of 50 o C, making this strain and this low-cost agroindustrial residue worthy of further investigation and potentially feasible for a wide range of biotechnological applications.

“…Ensilaging of pineapple peels produces methane as a biogas. Anaerobic digestion occurs and the digested slurry is used as animal, poultry and fish feeds or organic fertilizers [13]. In studies by Correia et al [14], Rhizopus oligosporous was used to produce enhanced levels of free phenolics from pineapple residue in combination with soy flour as potential nitrogen source.…”

A major economical industrial challenge from pineapple (Ananas sp.) processing contributing to environmental pollution is the organic side-streams of pineapple. The physicochemical, proximate and sensory properties of organic sidestream pineapple syrup (OSPS) developed from Smooth cayenne, Sugar loaf and MD 2 pineapple varieties were evaluated. Organic side-stream pineapple syrup developed from MD 2 recorded the highest moisture content with a corresponding water activity. The colour change in OSPS was significant among the three varieties and Sugar loaf variety deviated from the standard yellow colour more than Smooth cayenne and MD 2 varieties. This was buttress by the high Total Soluble Solids in 10% and 20% dilutions of Sugar loaf. The OSPS was acidic. In bread, incorporating 5% OSPS (w:w) of Sugar loaf recorded the highest percentage acceptability among the pineapple varieties. Interestingly, in the production of cakes with 15%, 20% and 30% OSPS, MD 2 recorded the highest percentage overall acceptance. For bread and cake, there was varied significance (P < 0.05) of the sensory properties for appearance, colour, aroma, taste, texture, crust, mouthfeel and overall acceptance. Notably, cake and bread with incorporated OSPS of 15% MD 2 and 5% Sugar loaf was more acceptable.
