Serological characterization of allergens in poppy seeds
Clinical and Experimental Allergy, 1999Background and objectivePoppy seeds in food can induce immediate‐type allergic reactions ranging from mild local symptoms to severe anaphylactic reactions. Previous publications showed that poppy seeds cross‐react with other plant‐derived allergens. The IgE‐binding components have not been defined so far.MethodsWe analysed sera from 11 patients with ...

Poppy Seeds: Implications of Consumption
Medicine, Science and the Law, 1992Three white poppy seed samples of Papaver somniferum L were found to contain total morphine (free and bound) in the range 58.4 to 62.2μg/g seeds and total codeine (free and bound) in the range 28.4 to 54.1μg/g seeds. Soaking seeds in water was found to remove 45.6 per cent of the free morphine and 48.4 per cent of the free codeine. In ingesting a curry

Lipolytic activity of poppy seed
Food / Nahrung, 1980AbstractCrude lipase emulsion from poppy seed hydrolyses its endogenous substrate at an optimum pH of 4.9 and optimum temperature of 22‐25°C. The lipase emulsion is stable up to 50°C. The enzyme is activated by low concentration of calcium ions; at higher concentrations a partial activity drop occurs. The addition of sodium chloride decrease the lipase

Investigation of Turkish Poppy Seeds and Seed Oils
Chemistry of Natural Compounds, 2004The oil yields, fatty acid compositions, and total protein contents of three varieties of Turkish poppy were investigated. Solvent extraction of yellow seed gave the highest oil yield (49.2%), while white seed (36.8%) and blue seed (33.6) showed considerably lower yields.

The poppy seed defense: a novel solution
Drug Testing and Analysis, 2013A major toxicological challenge is distinguishing whether morphine in urine, in the absence of 6‐monoacetylmorphine (6‐MAM), originates from ‘street’ heroin use or poppy seed ingestion. Manufacturing byproducts from the synthesis of illicit heroin include those that originate from the reaction of acetic anhydride with the alkaloid impurity, thebaine ...
