| The development of a sensory evaluation structure inside a reasearch institute is presented using few examples of data processing collected during training tests followed by volunteers. Statistical methods are proposed to evaluate various aptitudes of each panel member : aptitude to describe objectively the sensorial characteristics of marint. products, aptitude to discriminate flavors, to memorize odors, aptitude to rank samples according to the intensity of one characteristic, attitude of each person towards a scoring scale and also aptitude to give reliable answers. These methods, though widely used (Principal Component Analysis, Correspondence Analysis) give a synthetical view of individual qualities and also general aptitudes of the group. |

| The production of peptaibols by a marine-related Trichoderma longibrachiatum strain was studied using electrospray ionisation multiple-stage ion trap mass spectrometry (ESI-MSn-IT) and gas chromatography/electron impact mass spectrometry (GC/EI-MS). Two major groups of peptaibols were identified, those with long sequences (20 amino acids) and others with short sequences (11 amino acids). This paper describes the methodology used to establish the sequences of short peptaibols in a mixture without previous individual separation. Nine peptaibols were identified. Among them, eight are new, namely as trichobrachin A I-IV (Aib(9)-Pro(10) sequence) and as trichobrachin B I-IV (Val(9)-Pro(10) sequence). Original Pro(6)-Val(7) and Val(9)-Pro(10) sequences have to... |
