“…The lowest result was achieved by Bamano cultivar (88.61, I%). A similar result was reported by Lu et al (2020), who established that TPC values could be positively correlated with the DPPH values (Lu et al, 2020). However, Bamano variety had demonstrated the highest ABTS scavenging activity results (60.34, I%), followed by Sugarland (32.50, I%) and Dulcemiel variety (26.63, I%).…”

Tomato (Solanum lycopersicum) is a dietary source of bioactive compounds and breeding programs continuously create new cultivars with different nutritional and organoleptic characteristics. The aim of this work is to provide a quality and safety assessment of new tomato cultivars: Bamano, Dulcemiel and Sugarland. Eight biogenic amines, total phenolic content and antioxidant activity (DPPH and ABTS assays) have been determined. Tyramine was not detected in any samples. Sugarland was characterized by a high content of serotonin (266.87 ± 11.16 mg/kg) and phenolic compounds (303.15 ± 21.62 mgGAE/kg). Moreover, multivariate statistical analyses were applied to the data matrix.

“…Besides UT being used as a texture-improving pretreatment, previous studies show that ultrasonication, acting as an abiotic elicitor, shows capabilities to initiate stress response such as accelerating enzymatic activities [95] , which significantly alters the production of primary and secondary metabolites, and minerals during rice germination and storage [96] , [97] , [98] , [99] . Similarly, enhanced nutritional attributes are also observed in ultrasonic-treated crops such as wheat [100] , oat [101] , soybean [102] , broccoli [103] , and tomato [104] , [105] . Furthermore, UT bean and lotus seeds offer a possibility in increment germination productivity in a larger-scale farm [49] .…”

“…Therefore, it is reasonable to postulate that the increase in TPC after sonication may also be affected by the enhanced GABA level and the activated polyphenol synthase in coffee leaves. Moreover, ultrasound treatment may also enhance the recovery of TPC in coffee leaves (Lu et al, 2020). However, detailed mechanisms need further investigation.…”

In this study, the accumulation of γ-aminobutyric acid (GABA) in coffee leaves under ultrasonication and the impacts on total phenolic content (TPC), the activities of glutamate decarboxylase (GAD) and GABA transaminase (GABA-T), and angiotensinconverting enzyme (ACE) were investigated. The pH, incubation time, and ultrasonic power were the three most important factors that affected the accumulation of GABA. Coffee leaves treated with 20/40 kHz ultrasound have the highest GABA and the greatest GAD and ACE inhibitory activity. After optimization with a Box-Behnken design, GABA content was increased by 1.6 times under the optimal conditions of pH 5.9, incubation time 6.6 hr, and ultrasonic power 150 W. Our study indicated that ultrasonication activated GAD while inhibited GABA-T, thereby leading to an increase in GABA and ACE inhibitory activity. Ultrasonication also enhanced TPC; however, long time incubation caused the oxidation of phenolic compounds, and thus, affected the ACE inhibitory activity.Novelty impact statement: This is the first research that studied the enrichment of Gamma-aminobutyric acid (GABA) in coffee leaves using ultrasound stress. GABAenriched coffee leaves can be used to prepare tea-like beverage or natural health products to prevent hypertension, anxiety, and sleeplessness.
