Abstract

Purpose

This study aims to evaluate the use of vacuum impregnation (VI) for developing vitamin E fortified fresh‐cut apples (Fuji).

Design/methodology/approach

A 20 per cent high fructose corn syrup (HFCS) or edible coating materials of 1 per cent hydroxypropyl methylcellulose (HPMC) and 1 per cent calcium caseinate (CC) were used to make VI solutions, and 0.4 per cent α‐tocopherol acetate, 7.5 per cent gluconal cal\tf="Pi3" \char"31 (GC) and 0.04 per cent zinc lactate (ZL) were incorporated into the VI solutions. Vitamin E content, color, and selected physicochemical properties of fortified fresh‐cut apples were analyzed.

Findings

Results showed that VI treatment with 20 per cent HFCS solution containing 0.4 per cent α‐tocopherol acetate increased vitamin E content up to 21.8 mg in 100 g of fresh‐cut apples, while 12.0 mg and 20.2 mg vitamin E were achieved when using 1 per cent HPMC or 1 per cent CC as VI solutions, respectively. Calcium and zinc content were also increased to 146.6 mg and 1.7 mg in 100 g of apples, respectively, when adding 7.5 per cent GC and 0.04 per cent ZL along with the vitamin E into the VI solutions. Use of HFCS, HPMC and CC as VI solutions resulted in different effects on the physiochemical properties of fresh‐cut apples. While HFCS is promising for vitamin E fortification and retention of natural apple color, HPMC and CC can be used to achieve similar vitamin E fortification with the least impact on the soluble solids and moisture contents of apples.

Originality/value

The study demonstrates that there is great potential for developing high quality, vitamin E and minerals fortified fresh‐cut apples using vacuum impregnation technology, thus further enhancing the health benefit of the apples.

Abstract

Purpose

This study aims to enhance the bioavailability and antioxidant function of vitamin E (VE) by combining it with inositol and choline, exploring their synergistic effects and underlying mechanisms.

Design/methodology/approach

An oxidative stress model in mouse hepatocytes was established using hydrogen peroxide to assess the antioxidant effects of combined VE, inositol and choline treatments. Cell viability, the levels of reactive oxygen species (ROS) and malondialdehyde (MDA) and antioxidant enzymes, including superoxide dismutase (SOD) and catalase (CAT), were measured to evaluate protective effects. α-Tocopherol (α-T) and α-tocopherol transfer protein (α-TTP) levels were assessed to determine VE bioavailability. Transcriptome sequencing was conducted to identify gene expression changes and pathways impacted by the treatment.

Findings

An optimal oxidative stress model was established with 641 µM hydrogen peroxide for 6 h. The combination of 20 µM VE, 1.5 mM inositol and 0.3 mM choline significantly improved cell viability, reduced ROS and MDA levels and increased SOD and CAT activities, indicating enhanced antioxidant protection. In addition, α-T and α-TTP levels were higher with this combination, suggesting improved VE bioavailability. Transcriptome analysis revealed that the treatment modulated key pathways linked to inflammation, cancer and lipid metabolism, particularly impacting interleukin-17 and nuclear factor kappa-light-chain-enhancer of activated B cells signaling, cytokine interactions and the alcoholic liver disease pathway.

Originality/value

This study demonstrates a novel approach for improving VE’s bioavailability and effectiveness through its combination with inositol and choline, providing insights that could inform antioxidant therapies and liver health interventions.

Abstract

Purpose

Ascorbic acid, a water-soluble antioxidant, is an essential component of the human diet and is known for its potent antioxidant properties against several diseases. In recent years, there has been increasing interest in the development of nonenzymatic sensors due to their simplicity, efficiency and excellent selectivity. The aim of this study is to present a selective and sensitive method for the detection of ascorbic acid in aqueous system using a new electrochemical non-enzymatic sensor based on a gold nanoparticles Au-NPs-1,3-di(4-bromophényl)-5-tert-butyl-1,3,5-triazinane (DBTTA) composite.

Design/methodology/approach

Using the square wave voltammetry (SWV) technique, a series of Au-NPs-DBTTA composites were successfully developed and investigated. First, DBTTA was synthesized via the condensation of tert-butylamine and a4-bromoaniline. The structure obtained was identified by IR, 1H NMR and 13C NMR analysis. A glassy carbon electrode (GCE) was modified with 10–1 M DBTTA dissolved in an aqueous solution by cyclic voltammetry in the potential range of 1–1.4 V. Au-NPs were then deposited on the DBTTA/GCE by a chronoamperometric technique. SWV was used to study the electrochemical behavior of the modified electrode (DBTTA/Au-NPs/GCEs). To observe the effect of nanoparticles, ascorbic acid in a buffer solution was analyzed by SWV at the modified electrode with and without gold nanoparticles (Au-NPs).

Findings

The DBTTA/Au-NPs/GCE showed better electroanalytical results. The detection limit of 10–5 M was obtained and the electrode was proportional to the logarithm of the AA concentration in the range of 5 × 10−3 M to 1 × 10−1 with very good correlation parameters.

Originality/value

It was also found that the elaborated sensor exhibited reproducibility and excellent selectivity against interfering molecules such as uric acid, aspartic acid and glucose. The proposed sensor was tested for the recognition of AA in orange, and satisfactory results were obtained.

Abstract

Purpose

This paper aims to investigate the effect of simulated body fluid (SBF) on biodegradation and tribological properties of ultrahigh molecular weight polyethylene (UHMWPE) and UHMWPE stabilized with α-tocopherol.

Design/methodology/approach

The samples of UHMWPE and UHMWPE stabilized with α-tocopherol were prepared by a hot-pressing method, and then immersed in SBF for one year. Tribological test was performed on a UMT-2 tribometer.

Findings

The crystallinity and tribological properties increased slightly after UHMWPE stabilized with α-tocopherol, whereas the O/C ration decreased slightly. The crystallinity and O/C ratio increased after all samples immersed in SBF for one year. This resulted in the deterioration of tribological properties and the wear mechanism change. The tribological properties change was smaller in UHMWPE stabilized with α-tocopherol than that in UHMWPE, because the oxidation resistance of UHMWPE was increased by α-tocopherol.

Originality/value

The results of the experimental studies demonstrated and compared the biodegradation behavior and tribological properties of UHMWPE, UHMWPE stabilized with α-tocopherol, and after they immersed in SBF for one year.

Abstract

Purpose

A major challenge facing the fresh‐cut industry is maintaining and preserving the quality of minimally processed or fresh‐cut produce. A low temperature regime, although insufficient, has been the main method of overcoming this challenge so far. Thus, methods preserving the quality and extending the shell life of minimally processed or fresh‐cut produce are needed. This paper seeks to propose that honey could be used to preserve the fresh‐like quality of minimally processed pomegranate arils and extend their shelf life.

Design/methodology/approach

Manually extracted pomegranate arils were treated with water as control, 10 or 20 per cent diluted honey solution each for five minutes, then held at 4°C for ten days. Changes in organoleptic and visual quality, softening, soluble solids content, pH, absorbance at 446 and 510nm, and total aerobic count were recorded during the ten‐day storage period.

Findings

The study found that honey solution dip treatments extended the fresh‐like quality of minimally processed arils by delaying quality loss, microbial development, and pigment changes.

Practical implications

The paper shows that honey dip treatment may be used, depending on commodity, to preserve quality and extend the shelf life of minimally processed or fresh‐cut produce in the food‐processing industry.

Originality/value

The study pays particular attention to minimally processed pomegranate arils, by adapting a potentially safe organic method, the use of honey dips.

Abstract

Purpose

The purpose of this paper is to evaluate the shelf-life of minimally processed pineapple when subjected to the use of different edible coatings.

Design/methodology/approach

The pineapples were peeled and cut into cubes. The gums were prepared by dissolving them in distilled water and then heated to total dissolution. After calcium chloride, citric acid and ascorbic acid and glycerol were added in the solutions. The pieces of pineapple were completely submerged in the respective solutions and then drained. Four treatments were obtained, namely: T1 – control treatment (pineapple without coating); T2 – pectin; T3 – tara; T4 – xanthan. The cubes were stored in PET by 12 days at 4±1°C. Analyzes were carried out of mass loss, pH, titratable acidity, soluble solids, microbiological and sensory analysis.

Findings

It was possible to observe that the use of evaluated coatings was efficient to maintain the conservation of minimally processed pineapple in all analyzes, when compared with the control sample. The treatment with tara gum showed the best results to those obtained by the other studied gums.

Practical implications

The study may help small-scale establishments to increase the shelf-life of minimally processed pineapple.

Originality/value

Tara gum reduced the mass loss, delayed the microbial growth and maintained the sensorial quality of minimally processed pineapples for a longer time.

Abstract

Purpose

This study aims to investigate the possible effect of Citrus latifolia (CL) extract on biomarkers of oxidative stress, including lipid peroxidation products in rats fed a high cholesterol diet

Design/methodology/approach

Hypercholesterolemia was induced by feeding normocholesterolemic rats 1 per cent cholesterol-enriched diet for 15 days. An experimental group (n = 20) was divided into two groups (n = 10) and fed the same diet with or without CL lyophilized aqueous extract (1 per cent) for four weeks. At day 28, ten rats from each group were killed.

Findings

Treatment with CL lyophilized aqueous extract compared with the untreated group had decreased plasma total cholesterol (TC) (−36 per cent), triacylglycerols (−48 per cent), isoprostanes values (−74 per cent) and reduced thiobarbituric acid reactive substances in erythrocytes (−21 per cent). However, the supplementation of CL peels in the hypercholesterolemic diet enhanced superoxide dismutase (+69 per cent), glutathione reductase (+30 per cent) and catalase activities (+34 per cent).

Originality/value

In hypercholesterolemic rats, administering CL extract ameliorates dyslipidemia and attenuates lipid peroxidation in tissues. These results suggest that CL could be beneficial in the primary treatment of hypercholesterolemia and oxidative damage caused by a high-cholesterol diet.

Abstract

Purpose

The skin is the largest organ of human, and its care and health are, therefore, important. Cosmetotextiles development transforms daily ordinary textile products into cosmetically active products, ending the need to actively apply the cosmetic substance.

Design/methodology/approach

The textiles can act as delivery systems of bioactive compounds such as vitamins, fragrances, metallic compounds and drugs, as well as some plant-based compounds. Encapsulation and grafting/coating technologies have provided these cosmetic ingredients with effective stabilization, sustained dermal delivery and prolonged dermocosmetic efficiency.

Findings

Current cosmetotextiles in the market claim to be moisturizing, cellulite-reducing, perfumed, body slimming, energizing, rejuvenating, refreshing, improving the firmness and elasticity of skin or reducing the appearance of fine lines and wrinkles. This paper provides an overview of the development history, important cosmetic ingredients and their applications and commercial cosmetotextile products available in the market.

Originality/value

For the past few years, the emergence of cosmetic textiles has created even further synergy between the benefits provided by products offered by the textile and cosmetic industries. Thus, cosmetic textiles appear on the market as part of two megatrends – one is a strong movement toward general well-being, and the second is embracing more technology into our everyday lives.

Abstract

The definition of the term “family” around the Western world is more heterogeneous than ever before and so are its roles and the social expectations of it. However, prisoners’ families (specifically parents and siblings) are expected to support their incarcerated son/brother as they are perceived responsible for his choices and as having the closest relationship with him. Based on a study of parents and siblings of incarcerated men in Israel, this chapter’s goal is to shed light on families’ choice to support their incarcerated son or brother and the struggles this choice entails. A thematic analysis of semi-structured interviews with 17 parents and 10 siblings of incarcerated men in Israel showed that nuclear family members may experience various struggles throughout the legal proceedings, including family hardships, negative social experiences, and negative experiences with formal institutions – all leading to social self-exclusion. Looking through the intersectionality lens, the findings show that when accumulating hardships that prisoners’ families experience encounter perceived harsh institutional systems of oppression, preordained marginalization can be deepened as families operate in opposition.
