According to the Commission Regulation (EU) No 1069/2009, these materials are classified in three categories according to their related risk. In 2011 Commission Regulation (EU) No 142/2011 established that meat and bone meal (MBM) and fat deriving from ABPs not intended for human consumption (category 1 and 2) are required to be permanently marked with glyceroltriheptanoate (GTH), at a minimum concentration of 250 mg kg–1 of fat, while category 3 processed animal proteins (PAPs) must not contain this compound. PAPs are bio resources, which could be used in a renewable and regenerative way in a circular economy model for a conscious usage of raw materials. The aim of this study was to provide information on GTH occurrence in MBM and, if any, in PAPs. Samples were collected from 2017 to 2021 and analysed by GC-MS. Detected non-compliant samples were exclusively of MBM category 1 and 2, probably due to the addition of an inadequate amount of GTH during the manufacturing processes. These results highlighted the importance of National Monitoring Programs as a useful tool to minimise safety related risk due to the misuse of GTH. Thus, investigating the critical points in feed supply-chain and sharing the information on its occurrence may help to improve animal and human wellness and safety.","PeriodicalId":12121,"journal":{"name":"Food Additives & Contaminants: Part A","volume":"14 1","pages":"1047 - 1052"},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82406339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These limits are related to the final product, but buyers often request maximum levels of Cd in the beans. However, to date, there is neither a clear understanding of the relationship between the specified levels of Cd in chocolate and cocoa derivatives and levels in harvested beans or soil nor of the effect of post-harvest processes on the levels of Cd in the final product. To address this, the fate of Cd concentration from soil to chocolate bar was followed in a single farm in Santander district, Colombia. The concentration of Cd in soils was measured using ICP-OES and correlated with soil pH, soil organic matter (SOM), and the use of P-based fertilisers. Cd concentrations were also measured in unfermented seeds, fermented and dried beans, shell, nibs, and chocolate. SOM (2.93–3.78%), soil pH (4.7–4.9), soil P concentration (120–132 mg kg−1) affect Cd availability. However, it is still unclear whether Cd concentration of P-based fertilisers (3–30 mg kg−1) is important or not. While post-harvest treatments did not affect the Cd concentration of beans (4.17 ± 0.8 mg kg−1 on average), the removal of the shell (6.57 mg kg−1) from the nibs (3.28 mg kg−1), as well as the percentage of cocoa mass used contributes to a reduction in Cd concentration in the chocolate bar (1.60 mg kg−1). This study provides clear indications on where research into mitigation measures should be focussed, as well as indicating the importance of carrying out analyses for Cd in the nib or cacao mass, rather than the whole bean, reducing Cd concentration by up to 40%.

Herein, a simple, sensitive and reproducible LC-MS/MS method was developed for the simultaneous determination of praziquantel and trans- and cis-4-hydroxypraziquantel in black goat tissues to guide the reasonable use of PZQ. The mean recoveries for three target analytes were 71.2 ∼ 117.6%, and the limits of quantification were 1.0 μg/kg. Twenty-five healthy black goats were administered a single dose of praziquantel tablets at a dose of 35 mg/kg of body weight for residue elimination study, The results revealed that praziquantel and 4-hydroxypraziquantel were rapidly depleted in goat tissues and the elimination half-lives did not exceed 1 day in all tissues except for muscle and lung.

Rice was used as the crop for a short-term exposure experiment. A modified QuEChERS pre-treatment combined with ultra-high-performance liquid chromatography–tandem mass spectrometry was used to extract and detect difenoconazole from rice plants, water and soil. The recoveries of difenoconazole were in the range of 72.8–110.5%, with a relative standard deviation of 2.4–19.5% for all the samples when spiked with 0.01, 0.1 and 1 mg kg−1 of difenoconazole, respectively. The limit of quantitation (LOQ) of this method was 0.01 mg kg−1. The exposure results showed that difenoconazole could be absorbed by rice plants and transmitted to different parts of rice plants in all the treatments. In the hydroponic experiment, difenoconazole was mainly distributed in the roots of rice regardless of whether irrigation or spraying was used. For rice cultivated in soil, difenoconazole mainly accumulated in leaves after the root irrigation treatment, whereas after the spraying treatment, the rice roots were the main site of accumulation of difenoconazole. This experiment extends our knowledge of the influence of the cultivation system and application mode on the translocation of difenoconazole in rice plants.","PeriodicalId":12121,"journal":{"name":"Food Additives & Contaminants: Part A","volume":"9 1","pages":"1100 - 1108"},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89138015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reduction of patulin contamination in food processing has always been the focus of research. In this study, nine yeast strains were applied for the brewing of apple cider and the fate of patulin was determined. In this process, the patulin contamination can be decreased by adsorption onto and degradation of yeast cells in the main fermentation (20.8–49.1%), as well as the adsorption removal during clarification (18.7–58%), inverted cans (21.3–31.4%) and aging (1.0–5.8%). Saccharomyces cerevisiae (1027) was selected to reveal the elimination mechanism of patulin in main fermentation. The decrease of patulin content was mainly due to degradation and the intracellular enzymes played a more important role than extracellular ones. In addition, the synthesis of enzymes was related to the induction of patulin. Furthermore, the degradation product of patulin in the main fermentation was identified as E-ascladiol, which is less toxic than patulin. Based on the representative strain of S. cerevisiae 1027, patulin contamination can be effectively eliminated during apple cider brewing. This study provides a new insight into eliminating patulin contamination in the brewing of apple cider.","PeriodicalId":12121,"journal":{"name":"Food Additives & Contaminants: Part A","volume":"30 1","pages":"1149 - 1162"},"PeriodicalIF":0.0,"publicationDate":"2022-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81174781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The samples were analysed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to determine the occurrence of multi-mycotoxin. The results revealed that 100% of samples throughout the maize-based poultry feed supply chain were spoiled with more than one mycotoxin. Fumonisin B1 (8.02–1,220 µg/kg) and fumonisin B2 (11.1–1,109 µg/kg) were the main mycotoxins detected at all sampling points throughout the feed supply chain. Zearalenone (ZEA) (6.63–7.50 µg/kg) was also detected in 11.7% (n = 6) (out of a total of 51) samples. As the supply chain progresses, a reduction in mycotoxin contamination was observed. Aflatoxins, ochratoxin A (OTA), deoxynivalenol (DON), HT-2, and T-2 toxin were not detected. The levels of mycotoxins detected throughout the supply chain were below the international regulatory limits, thus indicating the low risk of exposure to mycotoxins in maize-based poultry feed in Malaysia. Nevertheless, due to the presence of multiple ingredients in most food and feed, efforts to understand and address challenges associated with mycotoxins throughout the entire supply chain need to be more holistic to protect public health.","PeriodicalId":12121,"journal":{"name":"Food Additives & Contaminants: Part A","volume":"33 1","pages":"777 - 787"},"PeriodicalIF":0.0,"publicationDate":"2022-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88320948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
