Effects of packaging methods and temperature variations on the quality and microbial diversity of grouper (Epinephelus Lanceolatus) during cold storage

Microbial growth and its metabolism are the primary reasons for fish spoilage. In this study, the effects of temperature fluctuations and modified atmosphere packaging (MAP) on the quality and microbial diversity of grouper (Epinephelus lanceolatus) during cold storage were investigated. Fish fillets were packed in air packaging (AP), vacuum packaging (VP), MAP1 (40% CO2/55% N2/5% O2), and MAP2 (60% CO2/35% N2/5% O2), and stored at T1 (4 °C) and T2 (4–8 °C temperature fluctuations), respectively. Total viable counts (TVC), psychrophilic bacteria count, Pseudomonas count, and H2S-producing bacteria count all increased during cold storage. Pseudomonas, Serratia, and Carnobacterium were the dominant genera in AP, VP, and MAP2 at T1 storage, with relative abundances of 82.7%, 54.5%, and 57.3%, respectively. Temperature fluctuations accelerated the spoilage process of the grouper, and increased the relative abundance of Serratia in the samples, but had less effect on the composition of these spoilage bacterial members. The microbial community was more affected by the different gas atmospheres. MAP inhibited the growth of Pseudomonas and increased the relative abundance of Carnobacterium and Psychrobacter in the samples. Low temperature and MAP effectively suppressed the rise of pH, total volatile basic nitrogen (TVB-N), trimethylamine (TMA), thiobarbituric acid reactive substances (TBARs), and K values and maintained the water holding capacity (WHC) and sensory quality of the samples. Grouper had the longest shelf life under MAP2-T1 treatment. The MAP2-T1 samples maintained lower levels of TVB-N (151.8 mg/kg), TMA (7.6 mg/kg), TBARs (0.90 mg MDA/kg), and K value (48.5%) and higher levels of WHC (77.6%) on the 18th day, with a lower degree of spoilage compared to other samples.

Exploration of fruit parameters for non-destructive identification of calyx cavity in ‘Fuyu’ persimmon (Diospyros kaki L.)

ABSTRACT Calyx cavity is a common physiological disorder in many persimmon cultivars. It is characterised by a separation between the calyx and the surrounding flesh. The presence of calyx cavity in export fruit can lead to phytosanitary risks and reduced storage potential due to more rapid softening and increased chilling injury. Manual detection of calyx cavity at packing is very time-consuming and uneconomic. This work investigated the ability of non-destructive evaluation, combined with modelling, to identify calyx cavity in ‘Fuyu’ persimmons. Fruit were evaluated at harvest, followed by a period of nine-week storage in modified atmosphere packaging at 0°C. The presence and severity of calyx cavity was related with higher red colouration and fresh weight before storage. Using colour index data and weight data, binary classification of calyx cavity by linear discriminant analysis (LDA) resulted 74.1% correct segregation. The model correctly identified 70.5% of calyx cavity fruit (29.5% false negatives) and 77.4% of no cavity fruit (22.6% false positives). The use of non-destructive calyx cavity classification based on the evaluation of quality parameters is a starting point in providing the ability to segregate healthy fruit before packaging and storage. Further work is necessary to improve model performance before implementation is viable.

Preparation of modified atmosphere packaging based on the respiratory characteristics of cherry tomato and its freshness preservation application

Cherry tomato (Lycopersicon esculentum Mill.) belongs to the respiratory leap type of fruit, post-harvest respiratory metabolism exuberant, easy to lead to nutrient loss, tissue destruction, and then rotting and deterioration, seriously affecting its commercial value. Therefore, research on post-harvest preservation technology of cherry tomatoes is crucial for related industries. Spontaneous modified atmosphere film packaging technology can extend the storage period of fruits and vegetables by adjusting the gas concentration of the storage environment, so that the fruits and vegetables can be maintained at a level suitable for their storage. In this study, the respiration model of cherry tomatoes at different temperatures was established by measuring the respiration rate of cherry tomatoes at different temperatures. It was found that the respiration rate of cherry tomatoes increased with increasing temperature and gradually decreased with increasing storage time. T-test results showed that there was no significant difference between the experimental values and the predicted values. The chemical kinetic model and its equilibrium equation were used to determine the parameters of modified atmosphere packaging of cherry tomatoes. PEG/PVDF membranes and SPEEK/PEG/PVDF blend membranes were prepared with sulfonated polyether ether ketone (SPEEK), polyvinylidene fluoride (PVDF) and polyethylene glycol (PEG) according to the parameters of modified atmosphere membranes to keep cherry tomatoes fresh. The results showed that there was a significant effect of package method on the preservation parameters of cherry tomatoes, the SPEEK/PEG/PVDF membrane treatment group significantly reduced the weight loss rate of cherry tomatoes and maintained the lower film permeability and higher sound fruit rate, hardness, titratable acid (TA) content, VC content and total soluble solids (TSS) content of cherry tomatoes. It can effectively delay the ripening and senescence of cherry tomatoes and extend the fruit storage period.

Lamb meat colour is minimally affected under reduced oxygen concentration in modified atmosphere packaging

This study investigated how modified atmosphere packaging (MAP) with lower oxygen concentrations affects meat surface redness compared to standard 80% oxygen MAP for sheepmeat. Colour measuring instruments assessed redness (oxymyoglobin to metmyoglobin ratio and a*) in M. longissimus lumborum (loin) and M. semimembranosus (topside) from 50 Merino lambs. After 5 or 20 days of vacuum storage, meat samples were re-packaged into one of five MAP treatments (0, 20, 40, 60, or 80% oxygen), and colour was measured after 2, 6, or 10 days of retail display. Decreasing oxygen from 80% to 40% showed no negative impact on loin redness during retail display. Topside samples under 40% oxygen exhibited lower oxy/met values than 80% oxygen MAP at 2 and 6 days, with no difference after 10 days. This finding highlights the potential to reduce MAP oxygen content to 40% without compromising surface redness, potentially mitigating adverse effects on eating quality.

A Sustainable Material for Sheep's Cheese Wedges Stored under Different Atmosphere Conditions.

This study is based on the need to improve packaging sustainability in the food industry. Its aim was to assess the performance of a recyclable plastic material for semi-hard sheep's cheese wedges packaging as an alternative to conventional non-sustainable plastic materials. Four different packaging treatments (air, vacuum, and CO2/N2 gas mixtures 50/50 and 80/20% (v/v)) were studied. Changes in gas headspace composition, sensory properties, cheese gross composition, weight loss, pH, colour, and texture profile were investigated at 5 ± 1 °C storage for 56 days. The sensory analysis indicated that vacuum packaging scored the worst in paste appearance and holes, and air atmosphere the worst in flavour; it was concluded that cheeses were unfit from day 14-21 onwards. Air and vacuum packaging were responsible for most of the significant changes identified in the texture profile analysis, and most of these happened in the early stages of storage. The colour parameters a* and b* differentiated the air packaging from the rest of the conditions. As in previous studies using conventional plastic materials, modified atmosphere packaging, either CO2/N2 50/50 or 80/20% (v/v), was the most effective preserving technique to ensure the quality of this type of cheese when comparing air and vacuum packaging treatments.

Application of poly(L-lactic acid)-based films for equilibrium modified atmosphere packaging of “Kyoho” grapes and its favorable protection for anthocyanins

Grapes were packaged by different Poly (L-lactic acid)-based packaging films (PLTL-PLEL) and stored at 5 °C for 35 days to investigate the effects of equilibrium modified atmosphere packaging on the quality of “Kyoho” grapes during storage. Changes in physiochemical quality, antioxidant content and senescence of grapes were studied. Furthermore, UPLC-Q-TOF-MS/MS was used to observe and identify key factors influencing the variation of grape anthocyanins under different atmosphere conditions. Alterations in gas components and enzyme activities significantly impacted anthocyanin levels, highlighting oxygen concentration as the primary influence on total anthocyanin levels. The PLTL-PLEL50 packaging resulted in an approximate 5.7% lower weight loss and increased soluble solids by approximately 14.4%, vitamin C, total phenols and flavonoids reaching 60.2 mg/100 g, 8.4 mg/100 g and 7.2 mg/100 g, respectively. This packaging also preserved higher anthocyanin levels, with malvidin-3-glucoside and peonidin-3-glucoside at 0.55 μg/mL and 1.62 μg/mL, respectively, on the 35th day of storage.

Bioprotective potential of Latilactobacillus sakei and Latilactobacillus curvatus in smoked chicken legs with modified atmosphere packaging

The effects of inoculation with bioprotective bacteria (Latilactobacillus sakei and Latilactobacillus carvatus) on the bacterial succession, physicochemical properties, volatile organic compound (VOCs), and sensory attributes of smoked chicken legs stored in modified atmosphere packaging (MAP, 60% CO2 and 40% N2) at 4 °C for 28 days were investigated. Compared with the control (without inoculation), inoculation with L. sakei and L. curvatus inhibited the growth of common spoilage bacteria (Serratia proteamaculans, Weissella ceti, and Pseudomonas fragi) in smoked chicken legs stored in MAP. They significantly (P < 0.05) decreased the levels of lipid oxidation and spoilage markers such as ethanol, 1-octen-3-ol, carbon disulfide, cyclooctanol, 2,3-butanediol, and 3-methyl-1-butanol, slowed down the deterioration of the surface skin color and odor, and prolonged the shelf-life of the product. Inoculation with L. sakei and L. curvatus extended the shelf life of smoked chicken legs stored in MAP by 7 and 14 days, respectively.

Evaluation of the performance of a three-strains lactic acid bacteria cocktail for the control of Listeria monocytogenes on marinated lean pork

The aim of this study was to evaluate the addition of a cocktail of three lactic acid bacteria (LAB) (Lactococcus lactis, Lacticaseibacillus paracasei and Lactiplantibacillus plantarum) as a protective culture into marinated pork. The pork was artificially inoculated with two Listeria monocytogenes strains and stored for 12 days. Two packagings were used: vacuum or modified atmosphere packaging (MAP). LAB, L. monocytogenes, psychrotrophic bacteria, pH, aw, color, the metataxonomic profile and the sensorial quality of the product were evaluated. The growth of L. monocytogenes under vacuum and MAP was reduced with the use of the LAB up to 0.8 and 0.7 log10 CFU/g, respectively. LAB counts gradually increased, which was accompanied by a slight decrease in pH. In LAB samples, psychrotrophic bacteria showed a reduction at day 12 as compared to non-inoculated samples. Some minor differences were also observed among samples for color and sensory parameters. Regardless of the type of packaging, the microbiota of the marinated pork was dominated initially by Photobacterium and subsequently during storage by a diversity of LAB. The application of LAB could help to obtain a safe product, although further evaluation would be required to optimize the application of the LAB cocktail in real-scale commercial scenarios.

Impact of packaging atmosphere, oregano essential oil, and storage temperature on cold-adapted Salmonella Enteritidis and Salmonella Typhimurium on ready-to-eat smoked turkey

The hazard of diseases created by S. Enteritidis and S. Typhimurium is relatively high in turkey meat products. Combinations of preservation methods are utilized in many strategies, such as mild heat with decreased water activity, a changed atmosphere, refrigerated storage, and decreased heat treatment with some acidification. Within the domain of ready-to-eat food technology, a range of preservation methods are typically utilized to enhance shelf life, such as applying mild heat in tandem with reduced water activity, employing modified atmosphere packaging, utilizing refrigerated storage, and utilizing reduced heat treatment combined with acidification. This investigation aimed to determine how S. Enteritidis and S. Typhimurium grew when sliced ready-to-eat smoked turkey (RTE-SM) was stored at 0, 5, 10, and 15°C for various periods. The study also examined the effects of modified atmosphere packaging (MAP) (40% CO2 and 60% N2) and VP on these growth patterns. Total viable count (TVC), lactic acid bacteria (LAB), pH, and redox potential levels were determined. The control experiment on RTE-SM showed no Salmonella growth within 30 days of storage at any temperature. This indicated that the RTE-SM in use did not initially contain S. Typhimurium and S. Enteritidis. Results indicated that the storage of RTE-SM using a combination of VP, MAP, and MAPEO with storage at 0 and 5°C did not allow for the pathogen to grow throughout storage. In comparison, at 10 and 15°C after one day, which allowed for minor growth (0.17-0.5 log CFU/g)? In contrast, at 0 and 5°C, Salmonella survives until the end of storage (173 days). However, the combination of MAPEO with the same storage temperatures achieved the elimination of the pathogen in the meat after 80 days. The combination of both packaging systems with high temperatures (10 or 15°C) allowed for the multiplication and growth of the bacterium through the product's shelf life of more than 1 log CFU/g. Thus, a combination of MAP or MAPEO with low storage temperatures (0 or 5°C) inhibited the growth of the pathogen.

Improving the microbiological safety and quality of aquatic products using nonthermal processing.

Spoilage and deterioration of aquatic products during storage are inevitable, posing significant challenges to their suitability for consumption and the sustainability of the aquatic products supply chain. Research on the nonthermal processing of fruit juices, probiotics, dairy products, and meat has demonstrated positive outcomes in preserving quality. This review examines specific spoilage bacteria species and mechanisms for various aquatic products and discusses the principles, characteristics, and applications of six nonthermal processing methods for bacterial inhibition to maintain microbiological safety and physicochemical quality. The primary spoilage bacteria groups differ among fish, crustaceans, and shellfish based on storage conditions and durations. Four metabolic pathways utilized by spoilage microorganisms-peptides and amino acids, nitrogen compounds, nucleotides, and carbohydrates-are crucial in explaining spoilage. Nonthermal processing techniques, such as ultrahigh pressure, irradiation, magnetic/electric fields, plasma, and ultrasound, can inactivate microorganisms, thereby enhancing microbiological safety, physicochemical quality, and shelf life. Future research may integrate nonthermal processing with other technologies (e.g., modified atmosphere packaging and omics) to elucidate mechanisms of spoilage and improve the storage quality of aquatic products.

Sulfur dioxide generating pads containing different concentrations of sodium metabisulfite maintains postharvest quality of ‘Hicaznar’ pomegranate

This study investigated the effects of different sulfur dioxide (SO2) generating pads containing different concentrations of sodium metabisulfite (Na2S2O5) on the storage of ‘Hicaznar’ pomegranate fruit. For this purpose, the pomegranates were harvested at optimal harvest maturity (total soluble solids (TSS): 17.70 %, titratable acidity (TA): 1.57 % citric acid). The first, second and third groups were treated with SO2 generating pads containing different concentrations of Na2S2O5 (1.5, 3.0 and 4.5 g). The fourth group was control which received no treatment. The SO2 generating pads were placed on top of the fruit with butter paper containing holes were kept between the fruit and pads. All the treatments were packaged under modified atmosphere packages (MAP) and stored at 6 °C and 90–95 % relative humidity (RH). The fruit samples for quality analysis were taken at 45, 90, 120, 150 and 180 days (d) of cold storage (CS). Post removal, the samples from each treatment were kept at 20 °C for additional 3 d to determine shelf life (SL) performance of fruit. Extending storage duration showed increase in weight loss, h° values, total flavonoid content, carbon dioxide (CO2) levels and decay index while decrease in L*, C* values, appearance and taste scores, TSS content, TA, total phenolic content, total antioxidant activity, total anthocyanin, ascorbic acid, organic acids (citric, malic, succinic and oxalic acids) contents, phenolic compounds (gallic, protocatechuic and chlorogenic acid), oxygen (O2) levels and SO2 production in MAP. SO2 generating pads reduced weight loss and decay index. The highest taste value was recorded in 3.0 g SO2 generating pads. The highest h° value was in 1.5 g SO2 generating pads while the greatest total anthocyanin content in CS was in 3.0 and 4.5 g with maximum total anthocyanin content in SL was recorded in 1.5 and 4.5 g SO2 generating pads. SO2 generating pads exhibited maximum total phenolic content, total antioxidant activity and gallic acid content as compared to control. There were no SO2 residues in pomegranate arils throughout the storage. It can be concluded that SO2 generating pads can be a potential tool to preserve the postharvest quality of ‘Hicaznar’ pomegranate for 180 d of CS.

Recent Progress in Modified Atmosphere Packaging and Biopolymeric Films and Coatings for Fresh Strawberry Shelf‐Life Extension

ABSTRACTStrawberry (Fragaria × ananassa) is a valuable crop cultivated worldwide. This fruit is mainly consumed fresh and is an important source of vitamin C, fat‐soluble vitamins and carotenoids. However, fresh strawberries (FS) have a limited shelf life. Conventionally, the shelf life of FS has been extended using refrigeration coupled with modified atmosphere packaging (MAP) technology in traditional petroleum‐based polymeric films. Nonetheless, other packaging technologies such as biopolymeric packaging films and edible coatings can also be used to preserve FS with the advantage of presenting similar shelf‐life extension with lower environmental impact. This review article focused on the analysis of the main factors limiting FS' shelf life, as well as a critical discussion about the use of different packaging technologies as alternatives to increasing FS' shelf life. The revised literature revealed that FS are susceptible to microbial deterioration, weight loss and sensory quality decay. Traditional MAP technology can extend the shelf life of FS to 15 days, depending on the gas composition and storage temperature. Meanwhile, active biopolymeric films and edible coatings can be used as emerging alternatives to extend the shelf life of FS. In general, most studies have produced active films and coatings with the objective of reducing microbial growth, weight loss and sensory quality decay of strawberries during storage. Biopolymeric films and edible coatings applied in strawberries can increase the shelf life of these fruits to a similar extent as traditional MAP. The combination of MAP with biopolymeric films and edible coatings could be explored as an alternative to increase the shelf life of FS.

Development of chitosan/polycaprolactone-thymol Janus films with directional transport and antibacterial properties for meat preservation

Reducing contamination from percolate is critical to the preservation of foods with high water content, such as pork. This study aims to develop a novel active packaging material for meat preservation by precisely controlled dual-channel one-step electrospinning. Compared to traditional strategies of preparing Janus films, this method allows for greater flexibility and efficiency. The structure and properties of the Janus film are characterized by scanning electron microscopy (SEM), water contact angle (WCA), directional liquid transport investigation, Thymol release and permeation features, and biocompatibility evaluation. Moreover, the Janus film is applied to the packaging of pork with modified atmosphere packaging to demonstrate its practical application prospects in the food active packaging field. The results revealed that the two sides of the film showed completely different wettability, and the change rate of WCA increased with the increase of the scale of hydrophilic fibers. The permeation features of thymol loaded in the film was consistent with the results of antibacterial properties and biocompatibility assessment. Moreover, the Janus film can effectively prolong the shelf life, improve the quality and safety of the pork.

Impacts of some eco-friendly methods on the storage life of tomato fruits

The objective of current research was to explore the influence of several eco-friendly techniques, including modified atmosphere packaging (MAP), edible coating (EC), heat treatment and edible coating enriched with centaury oil (EO), on the postharvest storage of tomato fruit. Tomatoes (Solanum lycopersicum) cv. Newton were harvested red ripe and used in this experiment. Experimental studies were established on 5th February 2023. A total of 8 treatments were tested. They were: 1) control, 2) MAP, 3) MAP+EC, 4) EC, 5) MAP+EC+EO, 6) EC+EO, 7) hot air and 8) MAP+hot air. The experiments were continued for 30 days and the measurement points time intervals were defined as 5, 10, 15, 20, 25, and 30 days (six different measurements points), 384 fruits in total were utilized in the storage studies and 8 extra fruits were used at the start as a control to identify the fruit's initial qualities. The fruits were kept for 30 days at 6 to 8 °C and 90 to 95 % relative humidity. According to the study's findings, each treatment had a significant impact on the fruit's decay incidence, weight loss, vitamin C content fruit firmness, chilling damage and SSC. The study found that all treatments significantly improved the quality of the tomato fruits, except for SSC. The best results were obtained from the MAP+EC and MAP+EC+EO treatments. Tomato fruits can be stored at a temperature range of 6 to 8°C for up to 20 days, demonstrating the effectiveness of the treatments.

Improving the storage quality and suppressing off-flavor generation of winter jujube by precise micro-perforated MAP.

Traditional modified atmosphere packaging (MAP) cannot meet the preservation requirements of winter jujube, and the high respiration rate characteristics of winter jujube will produce an atmosphere component with high CO2 concentration in traditional MAP. Micro-perforated MAP is suitable for the preservation of winter jujube due to its high permeability, which can effectively remove excess CO2 and supply O2. In this study, a microporous film preservation system that can be quickly applied to winter jujube was developed, namely PMP-MAP (precise micro-perforated modified atmosphere packaging). An experiment was designed to store winter jujube in PMP-MAP at 20°C and 2°C, respectively. The quality, aroma and antioxidant capacity, etc. of winter jujube at the storage time were determined. In this study, the optimal micropore area required for microporous film packaging at different temperatures is first determined. To ensure the best perforation effect, the effects of various factors on perforation efficiency were studied. The gas composition within the package was predicted using the gas prediction equation to ensure that the gas composition of the perforated package achieved the desired target. Finally, storage experiments were designed to determine the quality index of winter jujube, including firmness, total soluble solids, titratable acid, reddening, and decay incidence. In addition, sensory evaluation, aroma and antioxidant capacity were also determined. Finally, the preservation effect of PMP-MAP for winter jujube was evaluated by combining the above indicators. At the end of storage, PMP-MAP reduced the respiration rate of winter jujube, which contributed to the preservation of high total soluble solids and titratable acid levels, and delayed the reddening and decay rate of winter jujube. In addition, PMP-MAP maintained the antioxidant capacity and flavor of winter jujube while inhibiting the occurrence of alcoholic fermentation and off-flavors. This can be attributed to the effective gas exchange facilitated by PMP-MAP, thereby preventing anaerobic stress and quality degradation. Therefore, the PMP-MAP approach is an efficient method for the storage of winter jujube.

Ready-to-use broccoli raab (Brassica rapa L. subsp. sylvestris) quality and volatilome as affected by packaging

Broccoli raab (Brassica rapa L.) is a cruciferous vegetable primarily grown in the southern regions of Italy. Distinguished from the more common broccoli head (B. oleracea), its edible parts consist of sprouts, buds, younger stems, and leaves. Considering the high perishability of broccoli raab, it is necessary to apply postharvest technologies to make it a ready-to-use product. In this paper, active modified atmosphere packaging (aMAP, closed at 3% O2 and 97% N2) was applied, in combination with two types of packaging materials (polypropylene/polyamide microperforated, PP/PA MF, and polypropylene, PP). Shrink-wrap packaging and air-storage were included as control measures. The purpose was to assess the effects of different packaging conditions on enhancing knowledge about volatile compound development and quality aspects of the produce. Both packaging materials resulted in a 10% accumulation of CO2, combined with 1% O2 for PP bags and 10% for PP/PA. Different gas mixtures led to varied sensory and volatile development in minimally processed broccoli raab during storage. PP exhibited the lowest odor score (1.2, well below the marketability limit) and the highest concentrations of off-odor-related volatile compounds (ethanol, acetaldehyde, dimethyldisulfide, dimethyltrisulfide, and methanethiol) while samples packed in PP/PA MF reached an intermediate odor score with superior visual quality evaluation up to 12 days of storage. Both packaging materials reduced weight loss compared to control samples, up to less than 2% and 6%, respectively. In conclusion, active MAP using PP/PA MF bags demonstrated the best suitability in maintaining broccoli raab quality, with a final gaseous composition of 10% O2 and 12% CO2 deemed optimal for storage.
