“…Rise of amplitude at peaks around 1653, 1541, and decline of amplitude at peak around 3273–3275 was shown that there was interaction with hydroxyl group and amino group between gallic acid. The peaks and changing behavior of amplitudes at peaks were found to be similar with gallic acid/fish gelatin film . By the interaction with gallic acid and chickpea‐based flour, formation of new hydrogen and covalent bonds lowered free hydrogen group.…”

Chickpea is an easily accessible nutritious legume. Besides, gallic acid is a widespread phenolic found in various plants. In this study, it is aimed to investigate the effects of pH (9 and 11), glycerol concentration (1 and 3% w/v of film solution) and gallic acid concentration (5 and 10% w/w of total solid) on color, opacity, mechanical strength, water vapor permeability (WVP), microstructure, chemical characteristic, antioxidant activity, and phenolic content of films. At pH 11, films are stronger, darker and have higher antioxidant activity. Higher glycerol concentration makes the films more flexible but less strong and more hydrophilic. Higher gallic acid concentration makes great contribution to the films by decreasing WVP but by increasing opacity, antioxidant activity, phenolic content, lightness, and elongation. Film containing glycerol of 1% and gallic acid of 10% and prepared at pH 11 was found to be a great combination for obtaining antioxidant rich edible composite films. HIGHLIGHTS:1. Chickpea flour-based active films were successfully obtained with addition of gallic acid. 2. Higher gallic acid concentration decreased WVP, increased opacity, antioxidant activity, phenolic content, lightness, and elongation. 3. Higher pH provided stronger mechanical properties, low lightness, and higher antioxidant activity. 4. Lower glycerol concentration resulted lower WVP and stronger tensile properties. 5. Chickpea flour-based active films at pH 11 with 1% glycerol and 10% gallic acid can be used as active packaging material in especially highly oxidative food products.

Supplementation with a Carob (Ceratonia siliqua L.) Fruit Extract Attenuates the Cardiometabolic Alterations Associated with Metabolic Syndrome in Mice

et al. 2020

The incidence of metabolic syndrome (MetS) is increasing worldwide which makes necessary the finding of new strategies to treat and/or prevent it. The aim of this study was to analyze the possible beneficial effects of a carob fruit extract (CSAT+®) on the cardiometabolic alterations associated with MetS in mice. 16-week-old C57BL/6J male mice were fed for 26 weeks either with a standard diet (chow) or with a diet rich in fats and sugars (HFHS), supplemented or not with 4.8% of CSAT+®. CSAT+® supplementation reduced blood glucose, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and circulating levels of total cholesterol, low-density lipoprotein (LDL) cholesterol (LDL-c), insulin, and interleukin-6 (IL-6). In adipose tissue and skeletal muscle, CSAT+® prevented MetS-induced insulin resistance, reduced macrophage infiltration and the expression of pro-inflammatory markers, and up-regulated the mRNA levels of antioxidant markers. Supplementation with CSAT+® prevented MetS-induced hypertension and decreased the vascular response of aortic rings to angiotensin II (AngII). Moreover, treatment with CSAT+® attenuated endothelial dysfunction and increased vascular sensitivity to insulin. In the heart, CSAT+® supplementation reduced cardiomyocyte apoptosis and prevented ischemia-reperfusion-induced decrease in cardiac contractility. The beneficial effects at the cardiovascular level were associated with a lower expression of pro-inflammatory and pro-oxidant markers in aortic and cardiac tissues.

“…This eliminates the need for direct incorporation of active substances in food, which is not a preferable preservation method, as the active substances can be deactivated by other food components, 12 and they may also affect the sensory properties of food products 13 . Previous studies have successfully incorporated various active agents, such as essential oils, 14 gallic acid 15 and fruit peel wastes 16 into FG films and were able to observe improvement in terms of the physical, mechanical and functional properties of the films.…”

Development and characterisation of gelatine/palm wax/lemongrass essential oil (GPL)‐coated paper for active food packaging

et al. 2020

This research focused on the enhancement of paper through the incorporation of a biodegradable and hydrophobic film coating with antioxidant properties. The effects of different lemongrass essential oil (LEO) concentrations (0–12%) on the physical, mechanical, microstructural, water‐resistance, antioxidant and biodegradable properties of gelatine/palm wax/lemongrass essential oil (GPL)‐coated paper were analysed. Uncoated paper was used as a control. The GPL‐coated papers were heat sealable and had significantly (p < 0.05) higher tensile strength and stretchability but lower stiffness than those of the control paper. The GPL‐coated paper incorporated with higher LEO concentrations showed a significant (p < 0.05) increase in the initial contact angle while also demonstrating significant (p < 0.05) reductions in the Cobb value and water vapour permeability. The GC–MS analysis revealed that LEO was highly dominated by monoterpenes, sesquiterpenes, and their oxygenated derivatives, supporting that all GPL‐coated papers have a good amount of total phenolic compounds and free radical scavenging activities, which improved significantly (p < 0.05) with higher LEO concentrations. In conclusion, the GPL film coating was capable of improving the physical, mechanical and functional properties of Kraft paper and has the potential to be applied for food products.
