“…These organic acids can easily penetrate cell walls in microorganisms, intracellular pH reduction and organic acid accumulation (Wang et al, 2014). Essential oils are mixtures of volatile organic compounds accounting for plant flavor and aroma (Veloso et al, 2020); they have low toxicity, which turns them into environment-friendly compounds (Marques et al, 2019). Clove (Syzygium aromaticum) presents eugenol, which is the main antimicrobial agent; it disrupts the cytoplasmic membrane, releases the ions and causes excessive loss of cellular components, a fact that leads to microbial cell death (Devi et al, 2010).…”

Sanitization is a crucial step for the microbiological control of ready-to-eat fruits. Chlorinated compounds are commonly used, but there is concern with their replacement due to their adverse effects on the environment and on public health. The aim was to assess the effect of sanitization treatments (with 1% citric acid and 0.5% clove essential oil -applied in combination or in separate) on the microbiological and physicochemical quality of apples. The sanitization step consisted in immersing of apple (160 g) in 500 mL of sanitizer solutions for 5 minutes. 200 mg L -1 sodium hypochlorite solution was used as reference treatment. Non-sanitized apples formed the control group. The presence of aerobic mesophilic bacteria, yeast and mold was analyzed, as well as pH, total titratable acidity and total soluble solids in apples after they were subjected to the treatments. Alternative treatments showed similar or better results for aerobic mesophilic bacteria, and yeast and mold reduction than sodium hypochlorite. The assessed physicochemical parameters did not evidence any impairment. The treatment combining citric acid 1% and clove essential oil 0.5% was the most efficient one among all the tested sanitizers and it showed the potential to be used during the sanitization.

“…Fresh-cut or minimally processed vegetables are characterized as small portions that are ready to eat (RTE) or to cook [ 1 ]. Consuming fresh leafy vegetables, such as lettuce, spinach, cabbage, and kale, has certain benefits for human health [ 2 , 3 ], and the interest in healthy and well-balanced diets has increased. This interest includes a higher demand for foods such as RTE vegetables [ 1 , 4 ].…”

“…Some technologies, such as ultrasound (US), can be combined with chemical cleaners or by themselves for fruit and vegetable decontamination post-harvest [ 3 , 12 , 17 ]. US is described as sound waves above the human hearing limit that could be applied in several industrial functions, such as food processing [ 19 , 20 ].…”

Ultrasound, Acetic Acid, and Peracetic Acid as Alternatives Sanitizers to Chlorine Compounds for Fresh-Cut Kale Decontamination

et al. 2022

Chlorinated compounds are usually applied in vegetable sanitization, but there are concerns about their application. Thus, this study aimed to evaluate ultrasound (50 kHz), acetic acid (1000; 2000 mg/L), and peracetic acid (20 mg/L) and their combination as alternative treatments to 200 mg/L sodium dichloroisocyanurate. The overall microbial, physicochemical, and nutritional quality of kale stored at 7 °C were assessed. The impact on Salmonella enterica Typhimurium was verified by plate-counting and scanning electron microscopy. Ultrasound combined with peracetic acid exhibited higher reductions in aerobic mesophiles, molds and yeasts, and coliforms at 35 °C (2.6; 2.4; 2.6 log CFU/g, respectively). Microbial counts remained stable during storage. The highest reduction in Salmonella occurred with the combination of ultrasound and acetic acid at 1000 mg/L and acetic acid at 2000 mg/L (2.8; 3.8 log CFU/g, respectively). No synergistic effect was observed with the combination of treatments. The cellular morphology of the pathogen altered after combinations of ultrasound and acetic acid at 2000 mg/L and peracetic acid. No changes in titratable total acidity, mass loss, vitamin C, or total phenolic compounds occurred. Alternative treatments presented equal to or greater efficacies than chlorinated compounds, so they could potentially be used for the decontamination of kale.

“…In the last two decades, H. diversicolor has been widely used in an integrated recirculating aquaculture system to bioremediation wastewater, recreational fishing (Bischoff et al, 2009; Pajand et al, 2017; Yousefi‐Garakouei et al, 2019). Many researchers turned their attention to polychaetes in aquafeeds due to the high content of unsaturated fatty acids, namely eicosapentaenoic acid (EPA: 20:5n‐3) and docosahexaenoic acid (DHA: 22: 6n‐3) (Bischoff et al, 2009; Leelatanawit et al, 2014; Wang et al, 2019) and arachidonic acid (ARA: 20:4 n‐6) (Jerónimo et al, 2020; Marques et al, 2019). H. diversicolor worms contain phospholipids, hormones like prostaglandin and thromboxane (Meunpol et al, 2010).…”

The ragworm, Hediste diversicolor, is one of the few polychaeta species to present a commercial interest in Iran. In this study, the effects of six oil sources in the diet, namely fish oil (FO), soyabean oil (SBO), canola oil (CAO), corn oil (COO), sunflower oil (SFO) and mixed vegetable oil (MO), on growth, survival, fatty acid profile and biometric measurements of H. diversicolor were conducted during eight weeks. Furthermore, the mean survival rate of H. diversicolor reared on MO (82.93 ± 2.01%) diet, vice versa SGR, WG, Final biomass and PER, was significantly (p < 0.05) lower than that H. diversicolor fed the FO (89.40 ± 3.00%) diet. These findings suggested that MO could supply sufficient essential fatty acids, especially n3 and n6 and effective on zootechnical performance, survival and gonad maturation for juvenile H. diversicolor and should be given to individuals considered for production of dry feeds (and cheaper) of H. diversicolor. The results revealed a higher proportion of n3 HUFA in whole body of H. diversicolor than those in the experimental diets and values of n‐3/n‐6 in H. diversicolor fed the vegetable diets ranged from 0.13 in the COO diet to 0.21 in the CAO diet, meanwhile the values of n‐3/n‐6 in H. diversicolor fed the vegetable diets were lower than that obtained for the MO treatment. The FA such as C16:0, C17:0, C18:0 and C20:4ω‐6 had a higher concentration in experiment groups than in control. Vegetable oils, especially mix vegetable oils, were economic alternatives to the expensive fish oil used in the H. diversicolor aquaculture industry.
