Following conventional Japanese agricultural practices, 16 pesticides were sprayed at the maximum application rates in three test fields. All target pesticides were detected at quantifiable levels in the peel (n=144). In contrast, the percentages of detected pesticides in the pulp and pits were 42% (n=61) and 36% (n=52), respectively. Most pesticide residues were present in the peel. For comparison, the pesticide residue levels in the whole fruits were determined based on three indices: the highest estimate (H), calculated using the measured residue levels in the pits and by replacing the ND residues in the pulp as the limit of quantification (LOQ) values; conventional estimate (C), calculated by neglecting all residues in the pits (0 mg/kg) and replacing the ND residues in the pulp as LOQ values; and the lowest estimate (L), calculated by neglecting all residues in the pits and the ND residues in the pulp (0 mg/kg). The L/C and H/C ratios ranged from 74% (L/C) to 106% (H/C). In seven of eighty-three cases with less than 90% difference, residue levels in the whole loquat fruits were low (≤0.06 mg/kg), with the actual range being equal to or below the minimum unit of 0.01. In comparison of three field datasets, the range of residue levels was estimated to be 2.77 mg/kg. Based on the results of separate analysis, handling of ND residues in the pulp and detectable residues in the pits did not significantly affect the calculated pesticide residue levels in the whole loquat fruits.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"43 1","pages":"62-69"},"PeriodicalIF":0.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91386882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a nationwide internet survey was conducted to clarify the understanding and attitudes of dietitians towards the FFC 1 year and 4 years after its introduction (Surveys were conducted in 2015 and 2019, respectively). In the survey of 1 year after the introduction, the ratio of recognition of the FFC was 98%; however, only 35% correctly understood the characteristics of the FFC. Similarly, in the survey of 4 year after the introduction, only 42% of dietitians correctly answered the characteristics. At 4 year after, 56% of dietitians currently or previously have used the FFC. The dietitians who had been consulted about the use of the FFC accounted for 22% and about the adverse events accounted for 15%. The advice they gave at the consultation differed according to their experience of the use of the FFC. Of the ones who never used the FFC, 25% referred no information sources for the FFC. The place to educate primarily working dietitians needs to be prepared to let them provide appropriate information to consumers to support self-care including the appropriate use of the FFC.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"62 1","pages":"20-27"},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25433820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several pretreatment methods, such as the steam distillation and Conway microdiffusion methods, have been established for the determination of cyanogenic glycoside concentrations in foods. However, these methods are time-consuming and have extremely low throughput. Therefore, we developed a simple and rapid method, called the purge method, to analyze cyanide compounds in seed-derived food products. Under this method, the aqueous extract of cyanogenic glycosides is treated with β-glucosidase in a midget impinger, after which the liberated cyanide is purged into an absorbing solution. The concentration of cyanide in the adsorbent is then quantified using 4-pyridinecarboxylic acid-pyrazolone reagent. A single-laboratory method validation study was performed using amygdalin at a concentration of 10 ppm as cyanide ion. The validation parameter results (trueness, 83.9%; repeatability, 1.18%; intermediate precision, 4.67%) indicated that the developed method was suitable, precise and accurate. The purge method was used to analyze cyanide concentrations in commercially available food samples. Of the 10 samples tested (loquat seed powder, apricot kernel powder, and plum seed powder), three samples were found to contain cyanogenic glycosides at concentrations of >10 ppm as hydrogen cyanide, with the highest concentration detected being 861 ppm. These results clearly demonstrated the applicability of our method in determining cyanogenic glycosides in seed-derived food samples.","PeriodicalId":54373,"journal":{"name":"Food Hygiene and Safety Science","volume":"62 5","pages":"162-165"},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39588260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
