Culture-dependent and culture-independent analytical methods were applied to profile the bacterial and fungal populations in three organic DLGVJs (kale, chard, and collard greens) during refrigeration. Plate count results showed that the initial total aerobic plate counts (APC) ranged from 6.49 ± 0.03 to 6.74 ± 0.08 Log CFU/mL, and the initial total fungal counts ranged from 5.19 ± 0.06 to 6.75 ± 0.04 Log CFU/mL in fresh DLGVJs. During refrigerated storage the pH of DLGVJs decreased as the storage time increased and the redness of the juices increased as well. The culture-dependent analysis revealed bacterial counts initially increased and then declined, while fungal counts showed an initial decrease followed by an increase. By the end of the storage, the highest APC and fungal population were observed in kale juice and chard juice (7.03 ± 0.05 and 6.70 ± 0.03 Log CFU/mL) respectively. 16S rRNA sequencing results showed that the dominant bacterial genera of spoiled DLGVJs at the end of storage included <em>Serratia</em>, <em>Leuconostoc</em>, and <em>Hafnia-obesumbacterium</em>, and the major spoilage fungal were composed of <em>Mrakia</em>, <em>Filobasidium</em>, and <em>Vishniacozyma</em>.

Recent evidence revealing high levels of substances like arsenic and lead in baby foods call for a thorough exploration of contaminants in various infant diets. The objective of this article is to compare the levels of contaminants in Commercial Baby Foods (CBFs) in comparison to Homemade Baby Foods (HMBFs), and Common Foods (CFs), to assess their relative safety for infants. A comprehensive review of studies published between January 2007 and February 2024 was conducted, focusing on original contaminant data in CBFs, HMBFs, and CFs for infants aged 6 months to 3 years. Out of 880 initial publications, 46 studies were selected. The findings reveal that CBFs generally contained lower levels of pesticides, fertilizer residues and toxins in comparison to HMBFs and CFs, while heavy metal and environmental contaminant levels were comparable across all three food types. Process contaminants and packaging substances were higher in CFs compared to CBFs. This complexity calls for a shift in the infant food safety discussion, promoting an evidence-based assessment of all food sources, including common foods. Additionally, our findings challenge the general belief that HMBFs are inherently safer than CBFs in terms of contaminant levels, suggesting that this view may be overly simplistic. These results highlight the need for unified safety standards across all food types, as stricter regulations for commercial baby foods do not extend to common foods used in homemade meals.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"169 ","pages":"Article 111018"},"PeriodicalIF":5.6,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Burm.) is a citrus fruit known for its high nutritional value and potent antioxidant activity. Lemon juice, obtained by squeezing the fruit, is widely used in the kitchen for its acidic taste to flavour dishes and drinks. It has also been attributed with various medicinal properties to treat conditions such as sore throat, fever, rheumatism and hypertension. Ensuring the quality and safety of lemon juice, as well as its geographical origin, is not easy due to the scarcity of analytical methods available for this purpose, which makes it difficult to detect adulterations. To meet this challenge of testing the authenticity and safety of lemon juice, multiple physicochemical parameters need to be evaluated, which is expensive and time-consuming, so it is of great interest to develop an alternative simple method. In this research, two alternative analytical methods were developed and optimized for the analysis of lemon juice samples based on headspace gas chromatography coupled to both mass spectrometry (HS-GC-MS) or ion mobility spectrometry (HS-GC-IMS). These new methods were compared with the method currently used in the food industry for quality control of juices, which is Fourier transform near infrared spectroscopy (FT-NIR). A total of 159 samples belonging to different lemon varieties were analysed by measuring the physicochemical parameters, FT-NIR spectra and fingerprinting of the juice samples based on the total volatile compounds profile by GC-MS and GC-IMS. Partial least squares (PLS) regression models were then constructed and all models were validated by paired tests with the values measured by the reference chemical methods. The models developed confirm that both HS-GC-MS and HS-GC-IMS methods are viable alternatives for predicting physicochemical parameters and ensuring lemon juice quality. Finally, the data were used to build chemometric models using orthogonal partial least squares discriminant analysis (OPLS-DA) to distinguish lemon juices according to the lemon variety used in their manufacture. Very promising models were obtained with the HS-GC-MS and HS-GC-IMS data, suggesting the potential use of the volatile profile for lemon variety confirmation. Consequently, fingerprinting represents an alternative proposal to the conventional method applied in the food industry based on the use of chemical reference parameters or the use of the NIR technique.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"169 ","pages":"Article 111027"},"PeriodicalIF":5.6,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, the current research aimed to assess the quality and safety of some extensively consumed fish and recognize more types of fish widely available in Egypt with reasonable costs, high nutritional values, good quality, and safe for human consumption. To achieve this goal, 100 fresh fish samples including red porgy, sardine, eel fish, grass carp, and common carp (20 from each) were taken from local fish markets in Giza and examined for chemical composition, bacteriological quality, deterioration criteria, sensory attributes, heavy metal contents, and health risk assessment. Among the examined fish, red porgy exhibited significantly higher protein and sensory scores along with significantly lower fat, bacterial count, pH, total volatile base nitrogen, and trimethylamine values in contrast to carp fish. Nevertheless, sardine and eel fish obtained the highest values of thiobarbituric acid, free fatty acid, and acid number versus red porgy. Surprisingly, the concentrations of lead in grass carp fish, mercury in all examined samples, as well as arsenic in common carp fish, were lower than the detectable limits. Despite the target hazard quotient and hazard index of all examined heavy metals being below 1 in all fish samples, it could not be confirmed that eating such fish causes acceptable non-carcinogenic health risks due to exposure from fish consumption does not account for the total daily exposure to the heavy metal from all dietary sources. Moreover, the carcinogenic risk of all examined heavy metals in fish samples was higher than 10<sup>−6</sup> indicating a high risk of carcinogenicity which needs great efforts to be reduced to the safe limits. In conclusion, the current study provides beneficial data to Egyptian society for choosing seafood with high nutritional value, good quality, and affordable prices.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"169 ","pages":"Article 111023"},"PeriodicalIF":5.6,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
