The Stability

Vegetable and animal oils are susceptible to the oxidation of their lipid components on storage. Polyphenols from apple peels are investigated as potential natural antioxidants used for stabilizing polyunsaturated fatty acid and preventing oxidation. The aim of this study was assessing the antioxidant efficacy of apple pomace as natural antioxidant in linseed and fish oils, stored in anaerobic conditions. Apple pomace was added to the linseed and fish oils stored for eight weeks to evaluate the antioxidant activity of their polyphenolic components. The total phenolic content, activity of DPPH, ABTS•+, FRAP, acid value (AV), peroxide value (PV), and fatty acid profile were analyzed in storage tests. We found that apple pomace, regardless of the oil content of the formulation, was capable of blanking 2,2-diphenyl-1-picrylhydrazyl radicals. The highest ability to reduce Fe3+ ions occurred in the samples containing 30% of the fish oil. The use of apple pomace comprising polyphenolic compounds improves the stability of linseed and fish oils in storage tests. Polyphenols in apple pomace show a high antioxidant potential, as indicated by their values of DPPH, ABST•+, and FRAP. The addition of apple pomace resulted in limiting the acid and peroxide values of the samples during storage.

Pasta was prepared by incorporation of Ocimum sanctum (Basil) for better textural and sensory properties. The pasta was incorporated with the leaf extract of Ocimum sanctum at different concentrations of control, 5, 10, and 15.The natural antioxidants present in the O. sanctum leaf powder that was incorporated in the fruit leather showed extended shelf-life over three months when compared with control, without any added preservative at ambient temperature. Also the nutritional stability of the product was studied under two flexible packages of polypropylene and polyester out of that the products packed in polypropylene showed better storage stability .

Background: The consumption of natural antioxidants is increasing due to the demand and tendency to natural foods. Punica granatum L. [Punicaceae] is a fruit with various bioactive ingredients. The effectiveness of this plant has been proved against various disorders such as hyperglycemia, hyperlipidemia, blood coagulation, infections, cancer, and dentistry. Among them, there are numerous researches on antimicrobial and antioxidant properties. Subsequently, the present study aimed to compile a review of those properties to outline this herb as a possible natural antioxidant and preservative. Methods: Synchronically, keywords "Punica granatum" with antimicrobial, or antibacterial, antifungal, antiviral, antioxidant and radical scavenging were searched through "Scopus" database up to 31st September 2019. Papers focusing on agriculture, genetics, chemistry, and environmental sciences were excluded and also related papers were collected. Results: Among 201 papers focusing on related activities, 111 papers have dealt with antioxidant activities focusing based on DPPH assay, 59 with antibacterial, on both gram+ and gram- bacteria, 24 with antifungal effects, mostly on Aspergillus niger and Candida albicans, and 7 papers with antiviral activities. There were about 50 papers focusing on in-vivo antioxidant activities of this plant. Conclusion: Taken together, botanical parts of P. granatum have possessed notable radical scavenging and antimicrobial activities that with these properties, this plant can be introduced as a natural safe source of preservative and antioxidant. Accordingly, P. granatum can be applied as excipient with the aforementioned properties in the pharmaceutical and food industries.

Immunohistochemical Analyses

Background: Cadmium (Cd) impairs gametogenesis and damages the blood-testis barrier. Objective: As the primary mechanism of Cd-induced damage is oxidative stress, the effects of two natural antioxidants, myo-inositol (MI) and seleno-L-methionine (Se), were evaluated in mice testes. Methods: Eighty-four male C57 BL/6J mice were divided into twelve groups: 0.9% NaCl (vehicle; 1 ml/kg/day i.p.); Se (0.2 mg/kg/day per os); Se (0.4 mg/kg/day per os); MI (360 mg/kg/day per os); MI plus Se (0.2 mg/kg/day); MI plus Se (0.4 mg/kg/day); CdCl2 (2 mg/kg/day i.p.) plus vehicle; CdCl2 plus MI; CdCl2 plus Se (0.2 mg/kg/day); CdCl2 plus Se (0.4 mg/kg/day); CdCl2 plus MI plus Se (0.2 mg/kg/day); and CdCl2 plus MI plus Se (0.4 mg/kg/day). After 14 days, testes were processed for biochemical, structural and immunohistochemical analyses. Results: CdCl2 increased iNOS and TNF-α expression and Malondialdehyde (MDA) levels, lowered glutathione (GSH) and testosterone, induced testicular lesions, and almost eliminated claudin-11 immunoreactivity. Se administration at 0.2 or 0.4 mg/kg significantly reduced iNOS and TNF-α expression, maintained GSH, MDA and testosterone levels, structural changes and low claudin-11 immunoreactivity. MI alone or associated with Se at 0.2 or 0.4 mg/kg significantly reduced iNOS and TNF-α expression and MDA levels, increased GSH and testosterone levels, ameliorated structural organization and increased claudin-11 patches number. Conclusion: We demonstrated a protective effect of MI, a minor role of Se and an evident positive role of the association between MI and Se on Cd-induced damages of the testis. MI alone or associated with Se might protect testes in subjects exposed to toxicants, at least to those with behavior similar to Cd.
