“…At temperatures above 120°C, the water hydrogen bonds weaken, thus resulting in high amounts of ionisation products of subcritical water. Another role of subcritical water is that it can perform as a catalyst (Paramita et al, 2019). Weak hydrogen bonds result in auto-ionisation of water into acid catalyst hydronium ion (H3O + ) and base catalyst hydroxide ion (OH -).…”

Gingerol and shogaol are two bioactive compounds of ginger which exhibit several positive effects on human health. The conventional method for shogaol preparation is considered ineffective because it causes losses to the environmental system, and the efficiency of the process is low. Reactive extraction with subcritical water is a method that is considered environmentally friendly for the separation of slightly polar components without using organic solvents. The advantage of the reactive extraction process with subcritical water is that it does not require a catalyst because the process is able to form hydronium ions which can act as a catalyst to convert shogaol into gingerol. The effect of time and temperature on the yields of subcritical water reactive extraction of gingerol and shogaol were investigated in the present work. Experiments were carried out at a fixed pressure of 2 bar, and a varied temperature of reactive extraction from 130 to 140°C. Ginger and shogaol contents were analysed from the samples every 10 min. The chemical profiling of the resulting ginger extracts was performed using HPLC-MS. Results showed that the best subcritical water process was at 2 bar, 130°C, and 20 min; shogaol concentration increased to 15.345%, and gingerol to 5.113%. For the reactive extraction time of longer than 20 min, the shogaol concentration of the extract decreased. When temperature was above 120°C, and water hydrogen bonds weakened, thus resulting in high amounts of ionisation products of subcritical water.

“…In this process, 0.036% zingiberene was obtained. The complete extraction procedure was conducted at 125 °C, with a ginger-to-solvent ratio of 0.08, an extraction duration of 20 minutes, utilizing water as the environment-friendly solvent, followed by a 9-minute aging period [24] . Another study of ginger extract was reported where gingerol was the active component.…”

Excessive and widespread use of commercially available synthetic pesticides against phytophagous insects in various agroecosystems has led to their successive bioaccumulation in the surrounding environment. This phenomenon diminishes biodiversity, increases insect resistance, and negatively impacts non-target species, including human health and the ecosystem. To combat this, safer and environmentally friendly alternatives to chemical pesticides are needed. One such alternative is plantderived extracts, which have shown potential effectiveness in pest control. Ginger has been recognized as a promising natural pest-controlling agent with high efficiency and low toxicity in plant pest and disease management systems. Zingiberene, shogaol, and gingerol are the active components of ginger that give it its potent biocidal qualities. These active constituents interfere with some insect metabolic procedures, such as chitin synthesis, respiratory systems, central nervous systems, ATP synthesis, protein synthesis, impaired sexual communication, and antifeedant. This review demonstrates different varieties of ginger found in India and its efficacy as a pest-controlling agent and an alternative to conventional pesticides. It also aims to gather all the available scientific data regarding the extraction of different ginger plant parts, their application, and the mode of action in pest disease control of plants.

“…In addition, high temperature above 120℃ can cause the weakening of hydrogen bonds resulting in large amounts of subcritical water ionization products. Subcritical water can also be a catalyst (Paramita et al, 2019). It is caused by weakened hydrogen bonds resulting in the auto-ionization of water into hydronium ion acid catalysts (H3O + ) and hydroxide ion base catalysts (OH -).…”

Kinetic modelling played a key role in the development of subcritical water extraction for bioactive compounds such as: shogaol and gingerol from ginger waste. Liquid-solid extraction kinetics could predict the extraction phenomenon and increase the efficacy of extraction process. The aim of this study was to develop a mathematical model of leaching kinetics and determine the rate constant of extraction process (k) of shogaol and gingerol in ginger pulp which is in the subcritical water phase. The research was carried out in two work stages, namely modeling and experimentation. The modeling was done by comparing three extraction kinetic models, namely pseudo first order, pseudo second order and the distribution coefficient. The model was postulated and validated with experimental data using Matlab. The subcritical water extraction process of shogaol and gingerol in ginger waste was occurred at 140 ℃ with a pressure of 3.5 bar. The extracts had been separated from raffinate and further analyzed using HPLC-MS. The results showed that the pseudo first order kinetic model described well the phenomenon of subcritical water extraction with regression values was 0.9882 for gingerol and 0.9682 for shogaol respectively. The rate constant of extraction process (k) for gingerol and shogaol were 0.1101 and 0.3130 , respectively. This showed that the shogaol extraction rate was higher than the gingerol extraction rate.
