“…Detection methods may either target the allergen, which is ideal, or indirectly target a marker for the allergen presence, which is more common. Method selection is often dictated by the availability of antibodies and primers, the identified target allergen, the food-processing history, the food matrix (van Hengel 2007, Kirsch et al 2009, Monaci & Visconti 2009, Tiwari et al 2010, Cucu et al 2013, Mandalari et al 2014, and the degree of allergen characterization, particularly human allergy epitopes (Poms et al 2004, Monaci & Visconti 2009). Chemical interactions between nontargeted proteins and the detection antibody pose additional problems when allergenic proteins from food matrices are analyzed (Cucu et al 2013, Montserrat et al 2015.…”

“…This point is illustrated by a comparative study of six commercially available kits for peanut allergen detection that reported a wide variation in sample recovery and sensitivities ( Jayasena et al 2015). Food matrix, analyte source (van Hengel 2007, Tiwari et al 2010, Cucu et al 2013, and food processing (Montserrat et al 2015) are also known to affect ELISA performance. It is therefore useful to determine immunoassay sensitivity, specificity, and robustness for optimal assay performance.…”

Food allergy is receiving increased attention in recent years. Because there is currently no known cure for food allergy, avoiding the offending food is the best defense for sensitive individuals. Type I food allergy is mediated by food proteins, and thus, theoretically, any food protein is a potential allergen. Variability of an individual's immune system further complicates attempts to understand allergen-antibody interaction. In this article, we briefly review food allergy occurrence, prevalence, mechanisms, and detection. Efforts aimed at reducing/eliminating allergens through food processing are discussed. Future research needs are addressed.

“…The consumption and demand for almonds are high due to their impact on human health as a nutrition stabilizer with their high nutrient content and also for their high levels of mono unsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) content [1][2][3]6]. Especially in recent years, the importance of fruit such as almonds which are rich oleic, linoleic and linolenic of unsaturated fatty acid (USFA) content has increased due to the positive effects on cholesterol and cardiovascular disease in humans [7,8].…”

Major fatty acids composition of 32 almond (Prunus dulcis [Mill.] Hara and Radin (1978) method were used. Fatty acids content were determined using gas chromatographic (GC) analysis. The datas were evalulated with SPSS 17.0 statistical program. Results: In the gas chromatographic analysis, palmitic acid (16:0), palmitoleic acid (16:1), stearic acid (18:0), oleic acid (18:1), linoleic acid (18:2), and linolenic acid (18:3) were determined to be 5.34%, 0.70%, 0.85%, 74.46%, 17.89%, and 0.75% respectively. Saturated fatty acids (SFA) 6.19%, unsaturated fatty acids (USFA) 93.81% and a rate of USFA/SFA of 15.40, monounsaturated fatty acids (MUFA) 75.16%, polyunsaturated fatty acids (PUFA) 18.65% and a MUFA/PUFA ratio of 4.32 were found. In the correlation analysis, the highest correlation coefficient (r=-0.988) was detected between oleic acid and linoleic acid. Relationships among almond samples were partially identified with the cluster analysis. Conclusion: In this study, the variations were found between almond genotypes collected from different locations in terms of fatty acids compositions. Besides, the almond genotypes that have high quality unsaturates fatty acids such as high oleic acids and low linoleik acids content were determened. Key Words: Almond, seeds fatty acid composition, correlation, cluster analysis Conflict of Interest: The authors declare no conflict of interest. ductivity, resistance to pests and diseases, etc.) were taken into account by human selection pressure when looking for the adequate genotypes adapted to local conditions and to the preference of the consumers. The genotypes having incorporated these highly selected traits represent very valuable germplasm for addressing future challenges in almond breeding. As a consequence, these genotypes are preserved, characterized in several almond collections and incorporated into advanced breeding programs [16]. Chemical composition of almond kernels has only been partially studied. This information would be crucial to increase the knowledge of their diversity, the nutritional and healthy value of the kernels, and the possibility of selecting the most adequate parents in a breeding program for increasing kernel quality [9]. In this study, fatty acid composition, correlation and relationship levels of 32 different almond genotypes distributing to East and Southeast Anatolia Regions seeds have been revealed. These findings can be used to identify almond fatty acids quality and selections of almond genotypes for breeding programs and serving to different productions. ÖZET Materials and Methods Almond seed sources32 different genotypes of Prunus dulcis (Mill.) D. A. Webb's mature seeds were collected from different localities of South and Southeast Anatolia Regions (Table 1). From these, the genotypes numbered 37, 42 and 53 are plain, the genotype numbered 43 is bitterish and all other genotypes are composed of sweet almonds.

The effect of fish matrix on the enzyme‐linked immunosorbent assay of antibiotics

Significant interference in the immunoassay of norfloxacin was observed in the presence of fish matrix. Some proteins and ions were demonstrated to contribute to the matrix effect investigated. Although the detailed mechanism is still unclear, the non-specific interaction between fish proteins and immunoglobulin G (IgG) or horseradish peroxidase (HRP) labelled IgG was assumed to be an important source of the matrix effect in immunoassays.
