“…From Fig.2, it can be concluded that inoculum concentration of 0.15-0.3% (w/v) and fermentation time of 15-24 h, are the useful condition for the production of VCO. The result of the study shows a similar agreement to Neela 14 and Aladin et al, 27 . They reported that for fermentation using Lactobacillus sp., the usage of inoculum concentrations exceeding its optimum value ended with the low quality of VCO product.…”

Fermentation by using Saccharomyces cerevisiae is a potential method to produce the Virgin Coconut Oil (VCO). A parametric study using Box-behnken design was used to evaluate interaction effect of stirring speed, inoculum concentration and fermentation time on the percentage of oil recovery. The results indicated that fermentation time is most significantly affecting the rate of oil recovery. The surface and contour plots show that the oil recovery is gained up to 88.607% for stirring speed of 175-250 rpm, inoculum concentration of 0.2-0.3% (w/v), and fermentation time of 16-24 hours. GC analysis results indicate that the high lauric acid content of 53.0249%, is obtained when stirring speed of 200 rpm, inoculum concentration of 0.3% (w/v) and fermentation time of 24 hours. A parametric study has been successfully implemented in the production of VCO using fermentation method with the coefficient of determination (R 2 ) of 97.57%.

“…As a result, the coconut milk substrate is broken because the bonding among carbohydrate, fats, and protein becomes loose and finally detached 26,27 . Also, when S. cerevisiae hydrolyze the carbohydrate (glucose), then acetic acid and water are produced.…”

“…Some key factors of the set up to consider include: walls of the reactor must be designed to support anaerobic reaction within, the source of heat must be capable of being regulated and capacity to produce heat varying from 100 o C to 1000 o C depending on the raw materials and the intended grade of the product. [15,16] in their reports showed the setup of a LS generation unit installed with multiple ilters and nitrogen gas sources connected to the reactor to regulate the gaseous composition. During the manufacturing process of the LS, the smoke generated from the pyrolysis of the raw material is condensed and collected as a solution.…”

“…Pyrolysis is de ined as the thermal breakdown of materials at higher temperatures in an inert atmosphere and normally involves a modi ication of the chemical constituents [17]. Most published reports about LS are unequivocal about the fact its antimicrobial properties, insecticidal properties, colour, and lavour of LS are determined by the temperature, moisture content of the wood and the kind of wood used to produce the smoke [16,18]. According to [19], the temperature used and conditions of processing contribute a greater variation between the condensates yielded than the differences between common wood types used.…”

“…These came about when concerns about negative environmental impacts, toxicity, residues, and insect resistance towards conventional pesticides begun rising [48]. When using LS as raw materials for insecticide, Grade 3 LS is often used [16].

Use of liquid smoke for sustainable food preservation and postharvest loss and waste reduction (A review)

The primary aim of every post-harvest technology is to prolong shelf life and maintain produce quality. Recent efforts to extend the shelf life of agricultural produces have culminated in the use of various methods, among which some have dangerous side effects to human health and the environment, others are just too expensive due to the high cost of production thereby making their usage unsustainable and uneconomical. Among the safe and sustainable alternatives under development, Liquid Smoke (LS) appears to have very remarkable potentials. However, the Postharvest Loss and Waste (PHLW) reduction potential of LS have been highly underrepresented in both scienti ic and non-scienti ic literature. This work, therefore, analyses and bring to light the potentials of LS for reducing postharvest losses and prolonging the shelf life of agricultural produce. The usage against insect infestation, microorganism attack, and physiological disorder of products are discussed. A careful compilation of recent literature reporting various waste materials for producing LS is also reported in this work. The active components (carbonyls, organic acids, and Phenols) responsible for its potency in reducing food loss are also discussed. Finally, a simple conceptual framework is used to illustrate the strategic and systematic role played by LS in reducing PHLW, conserving the environment, and contributing to Sustainable Development Goals (SDGs).

This study focuses on the utilization of agro‐residual corn‐cob biomass, waste plastic and the combination of both for pyrolysis reaction using thermal analysis. Circular bioeconomy is assured by closing all the resource materials loops through co‐pyrolysis process. The conversion profiles of corn cob pyrolysis at various heating rates reveal a three‐stage decomposition process, and plastic waste exhibits single stage degradation. Due to the interaction between the blended materials, additional degradation peaks arise during the co‐pyrolysis of waste plastic (PET bottles) and biomass (corn cobs). The apparent activation energy fluctuates in the range of 120–260 kJ/mol with the conversion, according to Flynn‐Wall‐Ozawa (FWO) and Kissinger‐Akahira‐Sunose (KAS) kinetic methods. Notably, for co‐pyrolysis the apparent activation energy is lower (168 kJ/mol using FWO) than the individual biomass (179 kJ/mol using FWO) and plastic (175 kJ/mol using FWO), suggesting a positive synergistic effect during charring. The liquid crude and char product analysis from corn cob pyorlysis through FTIR and XRD confirms the application of the products in energy and chemical processes. The results obtained in this study can be utilized for co‐pyrolysis reactor analysis specifically using waste plastic bottles that are accumulating in the environment.
