Trained sensory panellists’ response to product alcohol content in the projective mapping task: Observations on alcohol content,product complexity and prior knowledge

Projective mapping has been validated as a practical tool for the rapid sensory profiling of brandy products, although repeatability concerns necessitate repeated measurements in larger sample sets. The reason for poor repeatability could be linked to the complexity of the product type, as well as the physical and possibly psychological factors associated with its high alcohol content. To date no information has been published that tested the effect of these specific factors on panellist performance in projective mapping tasks. This study tested the effect of sample complexity and alcohol content on sensory panel repeatability and accuracy in projective mapping, using six types of commercial alcoholic beverages. In a second objective, the study also tested the effect of prior knowledge of alcohol content of a given product set on panellist performance in projective mapping. The results showed that complexity had the biggest impact on panel performance, while alcohol content had a secondary but decisive influence, largely due to its chemosensory fatiguing nature. Knowledge of the product alcohol content appeared to affect individuals differently, and also had an effect on the terminology used by the panellists to describe the products. The study also introduces the Relative Performance Indicator (RPI) as a new panel performance monitoring tool for projective mapping.

Behenamidopropyl Dimethylamine: unique behaviour in solution and in hair care formulations

The rise of ecological awareness among consumers and industry has impacted the cationic surfactants market. The most used cationic surfactants present some drawbacks in this sense. Therefore, new molecules are being studied and developed which fulfil eco‐toxicological requirements without losing performance. One of these surfactants is Behenamidopropyl Dimethylamine (BAPDMA). This biodegradable amidoamine, which converts into a cationic surfactant at acidic pH, shows outstanding water solubility, despite its very long alkyl chain. Its behaviour in solution has been exhaustively studied. The conditioning performance of this product is superior to that of commonly used cationic surfactants, providing a superior sensorial profile and improved combing force reductions on hair. Moreover, other applications for this product in the non‐ionic form have been studied, such as conditioning agent in 2 in 1 shampoos, where it also shows colour protection effects, and as gelling agent in hair colouration creams. This multifunctional and high performance profile, together with an improved biodegradation and aquatic toxicity compared with currently used cationic surfactants, make this product a very interesting eco‐friendly alternative for the hair care market.     

European classes for the reaction to fire performance of wood products

The new classification system for the reaction to fire performance of building products in Europe has been applied to five different product families of wood: Wood-based panels, Structural timber, Glued laminated timber, Solid wood panelling and cladding and Wood flooring as being ‘products with known and stable fire performance’. The European classification system includes two sub-systems, one main system for all construction products except floorings and the other for flooring products. Wood properties such as density, thickness, joints and types of end use application including different substrates have been studied thoroughly and are included in the classification. Most wood products fall in classes D-s2, d0 or D_fl-s1 (for floorings). Testing has been performed according to EN 13823 (2002) SBI- Single Burning Item test, EN ISO 9239-1 (2002) Radiant panel test, and EN ISO 11925-2 (2002) Small flame test. In all, more than one hundred wood products in different end use applications have been studied. Clear relationships between the main Euroclass fire performance parameters and product parameters (such as density and thickness) have been demonstrated. Tables with reaction to fire classification of different wood products and end use applications have been developed, approved by the European Commission and published in their Official Journal. This procedure is ongoing with further official decisions to be published.     

Chlorinated Quaternized Hexamine and Potassium as Preservatives for Milk Samples

A new product, a chlorinated quaternized hexamine [1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride], was evaluated as a replacement for potassium dichromate in preserving Dairy Herd Improvement milk samples. In a field study involving 383 Dairy Herd Improvement samples from 24 herds, samples preserved with dichromate tested .086% lower than those preserved with the new product. In another trial, duplicate samples preserved with the dichromate tested .102% lower than the samples preserved with the new product after 2 days; after 5 days the dichromate preservative depressed tests an additional .103%. In a laboratory study, refrigerated samples and those preserved with dichromate or the new product tested nearly the same on day 0, but dichromate preserved milk tested .099% lower at 5 days. The standard plate counts of milk preserved with either preservative were low during a 10-day laboratory test. One tablet of the new product in 28 or 56 ml of milk effectively preserved the milk for 3 wk, but the 56-ml samples had soured by 4 wk. Although it did not preserve 84- or 112-ml samples for even 1 wk, the new product was an adequate preservative for Dairy Herd Improvement milk samples.

石英坩埚打磨用金刚石端面铣轮的加工性能研究

石英坩埚,是拉制单晶硅和生产多晶硅铸锭的必要容器。石英坩埚制成后需使用金刚石端面铣轮对其底面进行打磨,目前进口的金刚石端面铣轮使用效果较好,但是价格昂贵,而国内生产的金刚石端面铣轮虽然价格相对便宜,但是质量不高,加工性能不稳定。我公司开发了一种新型生产工艺并制备了金刚石端面铣轮,且进行了金刚石端面铣轮对比打磨石英坩埚试验。结果表明：与采用常规生产工艺制备的金刚石端面铣轮相比,采用新型生产工艺制备的金刚石端面铣轮其使用寿命平均提高45%,且在打磨石英坩埚过程中加工效率比较稳定。
