Tomatoes include high levels of lycopene, which is a potent antioxidative, hypolipidemic, and antidiabetic phytochemical. The intake of lycopene is associated with a reduced risk of insulin resistance and metabolic syndrome. The aim of this study was to investigate whether tomato ketchup and tomato paste, major dietary sources for tomato and lycopene, could regulate hepatic lipid metabolism and adipogenesis. To investigate the regulatory effects of tomato ketchup and tomato paste, we prepared a tomato ketchup extract (TKE) and a tomato paste extract (TPE) in 80% (v/v) ethyl acetate for the experiment. TKE and TPE reduced lipid accumulation and key markers for gluconeogenesis and induced a higher rate of fatty acid oxidation in HepG2 hepatocytes. In 3T3-L1 adipocytes, TKE and TPE increased adipogenesis and intracellular triglyceride accumulation, and stimulated glucose uptake. Peroxisome proliferator-activated receptor alpha and gamma expression levels were increased by TKE and TPE treatment. A single oral dose of tomato ketchup and tomato paste (9.28 g/kg) significantly improved glucose and insulin tolerance in mice. These findings suggest that lycopene-containing tomato ketchup and tomato paste may have beneficial regulatory effects in terms of energy metabolism in hepatocytes and adipocytes, and thus may improve blood glucose metabolism.

Unlabelled: This study was performed to evaluate the effects of added ingredients such as modified starch (MS), xanthan gum (XG), sugar, (SU), salt (SA), and vinegar (VIN) on the water mobility and physicochemical properties of model tomato ketchup and to investigate the correlation between the obtained variables and serum separation. The type and concentration of ingredients added to the tomato paste (TP) had significant effects on experimental variables, including the serum separation rate, water mobility, and viscosity. Serum separation was most severe in SU and VIN- added samples and minimal in MS and XG- added samples.

We explored the potential of thymol and menthol, which are natural hydrophobic compounds containing hydrogen-bond-donor and -acceptor group, as an extractant and developed an extraction method for the simultaneous determination of five Sudan dyes in tomato ketchup. To maximize extraction efficiency, we optimized key factors that affect the extraction process. The samples were then analysed using UHPLC-PDA.

Unlabelled: This study explores clean-label starch as a functional alternative to xanthan gum in food applications. The optimal blending ratio of ultrasound-treated rice and potato starch was found to be 25:75, resulting in a product with enhanced stability and viscosity similar to xanthan gum. A mathematical model was developed to adjust the viscosity of clean-label starch to match xanthan gum at various concentrations and shear rates, showing high predictive accuracy (R = 0.

Some raw potato flour has thickening properties, but its mechanisms and application in food systems are unclear. This study aims to investigate the difference between raw potato flour with thickening potential (RWT) and raw potato flour without thickening potential (RWOT) in application performance and the stability mechanism of RWT for ketchup. Results showed that the RWT has better rheological stability, less swelling power, lower amylose leakage (12.

Histamine, a pivotal chemical within certain cells of the human body, is responsible for eliciting various allergic symptoms, such as sneezing and a runny nose. In cases of allergies, where the immune system misidentifies typically harmless substances, such as certain foods or dust, as harmful, an efficient histamine sensor becomes imperative. This research introduces a novel sensing platform by employing a material comprising hydrothermally synthesized WS nanosheets and using this with a chitosan (CS) biopolymer on a screen-printed carbon electrode (SPE).
