D.C.W. Sanderson, L. Carmichael, Saffron Fisk, P Christensen, Henry Delincée, Hans Nootenboom, Jürgen Pfordt, S. Pinnioja, G Schreiber, Ute Wagner
Abstract
An international interlaboratory trial was conducted using thermoluminescence for the detection of irradiated shellfish, aimed at validating the method for routine use. Nephrops norvegicus, mussels, brown shrimps, black tiger prawns, and king scallops were presented as nonirradiated and irradiated to 0.5 and 2.5 kGy. The protocol called for ...... hiện toàn bộ
European Regulations for Labeling Requirements for Food Allergens and Substances Causing Intolerances: History and FutureJournal of AOAC International - Tập 101 Số 1 - Trang 60-69 - 2018
Martina Koeberl, Dean Clarke, Katrina J. Allen, Fiona Fleming, Lisa Katzer, N. Alice Lee, Andreas L. Lopata, Maria Said, Pieter Scheelings, Neil A. Shepherd, Robin Sherlock, James H. Roberts
Abstract
Food allergies are increasing globally, including numbers of allergens, the sensitization rate, and the prevalence rate. To protect food-allergic individuals in the community, food allergies need to be appropriately managed. This paper describes current Australian food allergen management practices. In Australia, the prevalence of food aller...... hiện toàn bộ
Japanese Food Allergen Labeling Regulation: An UpdateJournal of AOAC International - Tập 101 Số 1 - Trang 8-13 - 2018
Masahiro Shoji, Reiko Adachi, Hiroshi Akiyama
Abstract
The Japanese food allergen labeling regulation was designed to match real Japanese food allergy circumstances and also to be enforced effectively; thus, (1) regulated food allergens were selected by prevalence and seriousness according to food allergy surveys in Japan; (2) the detection criterion for ELISA monitoring, 10 μg food allergen pro...... hiện toàn bộ
Methodology for Determining Degree of Hydrolysis of Proteins in Hydrolysates: A ReviewJournal of AOAC International - Tập 93 Số 5 - Trang 1515-1522 - 2010
Shane M. Rutherfurd
Abstract
Degree of hydrolysis (DH) is defined as the proportion of cleaved peptide bonds in a protein hydrolysate. Several methods exist for determining DH; the most commonly used of these include the pH-stat, trinitrobenzenesulfonic acid (TNBS), o-phthaldialdehyde (OPA), trichloroacetic acid soluble nitrogen (SN-TCA), and formol titration methods.

Composition of Pomegranate JuiceJournal of AOAC International - Tập 95 Số 1 - Trang 163-168 - 2012
Dana A Krueger
Abstract
A database of 793 commercial pomegranate juices was analyzed to produce a profile for authentication of pure pomegranate juice. The database consisted of data from a mix of authentic and adulterated samples. Statistical tools were used to reduce the database to a stable sample set of 477 presumably authentic samples. The profile obtained (me...... hiện toàn bộ
Improved Extraction of Ginkgotoxin (4′-O-methylpyridoxine) from Ginkgo biloba ProductsJournal of AOAC International - Tập 88 Số 1 - Trang 26-29 - 2005
G. A. Lawrence, Peter Scott
Abstract
A simple extraction procedure was applied to the analysis of canned/packaged white nuts and Ginkgo biloba extracts. Extraction by shaking with water at room temperature was more convenient to use than a previously published Soxhlet procedure for analysis of packaged Ginkgo biloba seeds (white nuts) for ginkgotoxin; recoveries from spiked dri...... hiện toàn bộ
Analysis of Ginkgo biloba for the Presence of Ginkgotoxin and Ginkgotoxin 5′-GlucosideJournal of AOAC International - Tập 83 Số 6 - Trang 1313-1320 - 2000
Peter Scott, Benjamin P.‐Y. Lau, G. A. Lawrence, David Lewis
Abstract
Hot water extracts of Ginkgo biloba seeds were analyzed for the presence of ginkgotoxin (4′-O-methylpyridoxine) by reversed-phase liquid chromatography (LC) using methanol–0.05M KH2PO4 (1 + 9, v/v) adjusted to pH 3 as mobile phase. Detection was by fluorescence (excitation 280 nm, emission 370 nm). A straight line calibration curve was obtai...... hiện toàn bộ
