“…The Taguchi method (TM) omits the statistical theory and calculation part of the experimental design, and directly analyzes the experimental orthogonal table and experimental data, making it easier to understand and apply in the food industry practice. TM has been used to optimize the process of heavy metal extraction [ 28 ], essential oil extraction [ 29 ], ultrafiltration [ 30 ], drying foods [ 31 , 32 ], and baking parameters [ 33 ].…”

Chenopodium formosanum (CF), rich in nutrients and antioxidants, is a native plant in Taiwan. During the harvest, the seeds are collected, while the roots, stems, and leaves remain on the field as agricultural waste. In this study, di(phenyl)-(2,4,6-trinitrophenyl)iminoazanium (DPPH) radical scavenging ability and 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging ability experiments of seeds, leaves, stems, and roots were designed using the Taguchi method (TM) under three conditions: Ethanol concentration (0–100%), temperature (25–65 °C), and extraction time (30–150 min). The result demonstrates that seeds and leaves have higher radical scavenging ability than stems and roots. Many studies focused on CF seeds. Therefore, this study selected CF leaves and optimized DPPH, ABTS, total phenol content (TPC), total flavonoid content (TFC), and reducing power (RP) through TM, showing that the predicted value of the leaf is close to the actual value. The optimized results of CF leaves were DPPH 85.22%, ABTS 46.51%, TPC 116.54 µg GAE/mL, TFC 143.46 µg QE/mL, and RP 23.29 µg VCE (vitamin C equivalent)/mL. The DPPH and ABTS of CF leaves were second only to the results of CF seeds. It can be seen that CF leaves have the potential as a source of antioxidants and help in waste reduction.

“…Como subproducto de este proceso se obtiene el lactosuero, considerado un desecho y, por ello, vertido en efluentes y suelos, que genera problemas ambientales, dado que presenta alto poder contaminante por la cantidad elevada de materia orgánica que posee, en particular de lactosa, el sustrato usado como fuente de energía para el crecimiento microbiano (Khaire & Gogate, 2020;Louasté & Eloutassi, 2020). Por esta razón, se buscan alternativas para el uso de este subproducto lácteo y las investigaciones se enfocan en la obtención de probióticos del lactosuero, con el fin de mitigar su impacto ambiental, estableciendo avances tecnológicos en el tema de fermentaciones con microorganismos (bacterias y levaduras) con potencial probiótico, como una nueva alternativa para la industria láctea en todos los niveles (Guel et al, 2018;Huang et al, 2019;Rosa et al, 2020).…”

El objetivo de este trabajo fue aislar e identificar levaduras del lactosuero del queso Paipa y evaluar su potencial probiótico (in vitro) para su uso en alimentación animal. Las cepas se aislaron en caldo extracto de levadura-glucosa-cloranfenicol, se purificaron en agar PDA y se caracterizaron molecularmente. Se aislaron 10 cepas dentro de las que se encuentran Candida kefyr, Kluyveromyces marxianus, Pichia fermentans, entre otras. Las levaduras aisladas fueron evaluadas para evidenciar su uso potencial como probióticos en alimentación animal. Se determinó la resistencia a sales biliares (0,05, 0,1, 0,15, 0,20, 0,25 y 0,30 %), la estabilidad al pH del estómago (1,5, 2,0, 2,5, 3,0, 3,5 y 4,0) y resistencia al jugo gástrico (pH 1,5, NaCl de 0,2 % y pepsina de 0,32 %). En la prueba con diferentes concentraciones de sales biliares, las mejores cepas fueron K. marxianus (30_4) y P. fermentans (28_5). En la prueba de pH, el mejor desempeño lo tuvieron P. marxianus (30_4) y Yarrowia lipolytica. Finalmente, en la prueba de jugos gástricos se destacaron C. kefyr y K. marxianus (R_1). Las cepas que presentaron buen desempeño en casi todas las pruebas fueron K. marxianus (30_4) y P. fermentans (28_5), de tal forma que estas levaduras aisladas del lactosuero de queso Paipa tienen potencial en la aplicación como probióticos en la alimentación animal.

“…There have been several studies on optimisation using Taguchi schemes and response surface methodology (Lin et al, 2019;Raji and Oke, 2019;Sharma and Sinsek, 2020;Saari et al, 2020;Varkey et al, 2020;Sharma and Mohal, 2020). For instance, Taguchi schemes have been applied in food manufacturing (Noorwali, 2003;Al-Darrab al., 2009), chemical manufacturing (Khaire and Gogate, 2020), maintenance (Ighrarwe and Oke, 2016;Raji and Oke, 2019) and clothing industry (Zeydam, 2008). Furthermore, response surface methodology has been used in leather manufacture (Lin et al, 2019), sugar beet industry (Sharma and Sinsek, 2020), intimate apparel industry, (Wu et al, 2012), veneer panel manufacturing (Saari et al, 2020) and welding (Varkey et al, 2020;Sharma and Mohal, 2020).…”

PurposeThere is growing evidence of a knowledge gap in the association of maintenance with production activities in bottling plants. Indeed, insights into how to jointly optimise these activities are not clear. In this paper, two optimisation models, Taguchi schemes and response surface methodology are proposed.Design/methodology/approachBorrowing from the “hard” total quality management elements in optimisation and prioritisation literature, two new models were developed based on factor, level and orthogonal array selection, signal-to-noise ratio, analysis of variance and optimal parametric settings as Taguchi–ABC and Taguchi–Pareto. An additional model of response surface methodology was created with analysis on regression, main effects, residual plots and surface plots.FindingsThe Taguchi S/N ratio table ranked planned maintenance as the highest. The Taguchi–Pareto shows the optimal parametric setting as A4B4C1 (28 h of production, 30.56 shifts and 37 h of planned maintenance). Taguchi ABC reveals that the planned maintenance and number of shifts will influence the outcome of production greatly. The surface regression table reveals that the production hours worked decrease at a value of planned maintenance with a decrease in the number of shifts.Originality/valueThis is the first time that joint optimisation for bottling plant will be approached using Taguchi–ABC and Taguchi–Pareto. It is also the first time that response surface will be applied to optimise a unique platform of the bottling process plant.
