“…Multivariate statistical methods have been widely used in the authentication of foods to enable the visualisation of data when more than three variables have been measured (Arvanitoyannis et al, 1999;Tzouros & Arvanitoyannis, 2001;Arvanitoyannis & Van Houwelingen-Koukaliaroglou, 2003;Arvanitoyannis et al, 2005;Vlachos & Arvanitoyannis, 2008;Arvanitoyannis et al, 2008;Arvanitoyannis & Vlachos, 2009). The mathematical basis will be representation and manipulation of data by vectors and matrices (Kellner et al, 1998).…”

Summary This study aims to evaluate some Tunisian olive genetic resources using fatty acid, triacyglycerol and sterolic compositions and to classify the cultivars according to their fruit genotype and to their respective geographical origin (North, Centre and South). manova results showed that the studied cultivars presented highly significant differences regarding all the variables (P < 0.01). The most discriminant variables of fatty acids are C17:1 (F = 98.468), C16:0 (F = 92.994), C18:1 (F = 60.865), C18:1/C18:2 (F = 44.632) and C18:2 (F = 40.167); those of triacylglycerols are POP (F = 123.34), LLL (F = 122.944), LnLO (F = 98.363), POO (F = 93.357) and LOO (F = 90.42), while sitostanol (F = 289.171), campestanol (F = 192.792) and campesterol (F = 160.724) have the higher discriminant power among sterol compounds. Principal component analysis (PCA) was performed on the data of each chemical parameter to explore their usefulness for the discrimination of eleven monovarietal olive oils. Best differentiations among cultivars were obtained with triacyglycerol and sterolic compositions. The spatial distribution of the different oil samples using all the collected data showed a good discrimination among olive cultivars. A strong resolution between the samples according to the geographical origin was obtained by means of factorial discriminant analysis (FDA) (λ = 0.002). Comparisons of the distances between classes were statistically significant (Fisher tests; P < 0.0001), and 90.91% of cross‐validated grouped cases are correctly classified. The obtained results could become an important tool for sorting out oils to a single cultivar or to a specific geographical area.

“…The contents of protein, starch, sugars and lipids were determined. An increase was recorded in TL overexpressing 14-3-3 protein from Cucurbita pepo 28 . Analysis of plants suggested that the function of the isolated 14-3-3 isoform is in the control of carbohydrate and lipid metabolism.…”

“…The environmental variation on transgenic potatoes, should be examined more in food safety aspects as crops could be grown under different conditions, with respect to variation of protein expressions in potato tubers whether transgenic individuals could have significant deviation on their expression beyond the variation of their non-transgenic comparators. 38,39) In vitro mast cell activation studies are useful to understand the biological significance of differences in expression of allergenic proteins in plants. Recently, we developed an in vitro cell activation system using a humanized FceRI-expressing rat mast cell line (RS-ATL8).…”

To increase the quality and yield of crops, transgenic plants have been developed that show enhanced resistance to insects or herbicides, or improved growth and nutrient status. In addition, transgenic plants expressing proteins associated with stress responses are being developed in an effort to produce crops with greater resistance to stresses such as cold, heat, and salt.1) Genetic engineering of a transcriptional factor may affect expressions of multiple genes, therefore, there may be unintended effects on protein expression levels in transgenic plants. For appropriate safety assessment, therefore, it is important to evaluate the proteomics of transgenic plants, particularly with respect to allergenicity.Even after the establishment of the 2003 Codex guidelines for methods to assess safety of foods derived from transgenic organisms, there is still controversy regarding methods used to test their allergenicity.2) Allergenicity of foods derived from transgenic organisms has been evaluated using immunological methods such as immunoblots, histamine release assays, skin prick tests, and oral exposure. 3,4) Immunoproteomic analysis of allergens with sera from allergic patients is a useful method for comprehensively comparing unknown allergens as well as known allergens in extracts of foods derived from transgenic organisms. Previously, we reported application of the immunoproteome to assess allergenicities of GH-1 (growth hormone 1)-transgenic amago salmon 5) and enhanced green fluorescent protein (EGFP)-transgenic chicken meat.6) The two-dimensional difference gel electrophoresis (2D-DIGE) method, a gel-based proteomic technology, is useful for evaluating relative differences in protein expression, if any, between non-transgenic and transgenic crops. The CyDye DIGE fluors used to label samples are spectrally resolvable, size-and charge-matched fluorescent dyes. 7,8) The method enables analysis of one or more samples on the same gel and is highly sensitive, and has a wide range of detection.Potato (Solanum tuberosum) is a staple food that is consumed worldwide. Various transgenic potatoes have been developed and their food safety has been assessed using serological and proteomic techniques.9-11) Several cases of potato allergies have been reported, 12-16) and a major potato allergen that causes hypersensitive reactions has been identified as patatin (Sola t 1).17) Potato allergy is considered to be cross-reactive with latex or pollens, and their cross-reactive fruit and vegetables. [18][19][20] Other potato allergens, cathepsin D-, cysteine-, and serine protease inhibitors, all of which are members of the trypsin inhibitor family, have been designated as Sola t 2, Sola t 3, and Sola t 4, respectively. 21) These allergens make up approximately 70-80% of total soluble potato proteins. 22)In this study, we investigated the allergenicity of stresstolerant transgenic potatoes 23,24) To produce crops that are more tolerant to stresses such as heat, cold, and salt, transgenic plants have been produced those express stre...
