“…Previous results unambiguously show that pomegranate peel extract is a potential stabilizer for polymers [ 20 , 21 ]. However, as mentioned above, the existing information is insufficient and contradictory; further research is needed to establish the full potential of the substance.…”

“…In this latter case, active components were extracted from pomegranate peel by acetone by the researchers themselves. The findings of Xia et al [ 20 ] and Tátraaljai et al [ 21 ] obviously contradict each other on the efficiency of the extract as an antioxidant in an oxygen-rich environment.…”

“…They found that the extract is a good overall stabilizer, which protects the polymer during processing, against oxidation, and UV radiation, and it is at least as efficient as the phenol. Tátraaljai et al [ 21 ], on the other hand, found that although the extract protected PE very efficiently during processing, the long-term stability of the polymer was poor. In this latter case, active components were extracted from pomegranate peel by acetone by the researchers themselves.…”

“…However, as mentioned above, the existing information is insufficient and contradictory; further research is needed to establish the full potential of the substance. In our previous study, we merely wanted to establish the possibility to use the POM extract as a stabilizer and investigated its performance at a single concentration in comparison with industrial stabilizer packages [ 21 ]. On the other hand, the goal of this study was to obtain more information on the stabilization effect and efficiency of pomegranate peel extract.…”

“…An attempt is made to resolve the contradiction mentioned above and develop some ideas about the mechanism of stabilization. We used the results obtained in our earlier research as reference [ 4 , 21 ]. Conclusions and possible relevance for practice are briefly discussed in the final section of the paper.…”

Dry pomegranate peel was extracted with acetone and the extract was added to a Phillips type polyethylene. The concentration of the extract was changed from 0 to 1000 ppm in six steps and stabilization efficiency was checked by the multiple extrusion of the polymer followed by the characterization of chemical structure, processing, and residual stability. The results confirmed the excellent processing stabilization efficiency of the extract, but also the poor long-term stability of PE containing it in accordance with previously published results. The extract is amorphous and its solubility is relatively large in the polymer; thus, these factors cannot be the reason for the poor stabilization efficiency in an oxygen-rich environment. Chemical factors like the self-interaction of the polyphenol molecules, the stability of the radicals forming after hydrogen abstraction, and the lack of hydrogens with the necessary reactivity must be considered during the evaluation of the efficiency of the extract. These factors as well as the insufficient number of active hydrogens hinder the reaction of the additive molecules with oxygen-centered radicals, thus leading to inferior long-term stability. The extract can be used for the processing stabilization of polymers, but for applications requiring long-term stability, it must be combined with other natural antioxidants like flavonoids or Vitamin E.

Diabetes mellitus is a metabolic and chronic disease linked to lifestyle factors like dietary patterns and physical inactivity. This randomized clinical study aimed to develop a novel dietary intervention using pomegranate peel powder‐based multigrain chapatti to prevent diabetes. The product was formulated by incorporating pomegranate peel powder into a mixture of wheat flour, pearl flour, millet flour, and chickpea flour. The study included the formulation of various treatments (Tc, T1, T2, and T3) following product development, and these treatments were subjected to comprehensive assessments. The nutritional composition and antioxidant potential of the pomegranate peel powder‐based multigrain chapatti were analyzed. Sensory attributes, including taste, texture, and overall acceptability, were evaluated. Additionally, biochemical analyses, including blood glucose levels and HbA1C, were conducted to assess the impact of the interventions on blood glucose metabolism. The results revealed that the nutritional profile and phytochemical potential of the product improved significantly in treatment T3, which contained 15% pomegranate juice. Overall acceptability was found to be high for T3, indicating that the inclusion of pomegranate peel powder was well received in terms of taste and sensory qualities. Importantly, the clinical trial demonstrated positive outcomes in the intervention group receiving the pomegranate peel powder‐based multigrain chapatti. Blood glucose analysis and HbA1C assessments indicated that the consumption of this innovative dietary product contributed to improved blood glucose metabolism, suggesting its potential as a preventive strategy for diabetes.

Scutellaria baicalensis extract (SBE), as a natural phenolic antioxidant, was added to poly(butylene adipate‐co‐terephthalate) (PBAT) matrix. With the addition of SBE, both the short‐term and long‐term antioxidant activity of PBAT samples noticeably improved. The results showed that the oxidation onset temperature (OOT) value of the modified sample (PBAT‐SBE2.5 sample) is increased by 62°C versus neat PBAT. Compared with neat PBAT with decreased OOT value after 240 days of storage, the OOT values of modified samples showed no significant change after long‐term storage. The excellent antioxidant activity is attributed to the high total phenolic content in SBE, which provides significant free radical scavenging efficiency. Additionally, the introduction of SBE could effectively enhance the processing performance of the PBAT matrix, the melt flow rate of PBAT‐SBE2.5 increased by ca. 42.6%. Compared with neat PBAT, the addition of SBE has no obvious effect on the mechanical properties of the matrix, the tensile strength remains unchanged and the elongation at break of PBAT‐SBE2.5 retains 74%. Composting degradation experiment indicated that the SBE promoted the degradation of PBAT. Moreover, SBE could reduce the surface hydrophilic tendency of the film materials. All results reveal that SBE was a good natural multifunctional stabilizer for PBAT.Highlights SBE shows high total phenolic content and free radical scavenging activity. SBE improves the short‐term and long‐term antioxidant activity of PBAT. The addition of SBE promoted the degradation of PBAT films. SBE could effectively enhance the processing performance of the PBAT matrix.
