For fruits and their products, HPLC techniques for phenolics have been used to study the effect of processing, concentration, and storage on the phenolic composition of juices as well as a potential precursor for an off-flavor compound in juices. Phenolic analysis has been further applied to the detection of economic adulteration and especially to verify the authenticity of fruit juices. This is especially important when cheaper fruits can be added to more expensive ones in a fraudulent manner. In most fruits, the nonanthocyanin flavonoids consist mainly of flavonols and flavanols, with trace amounts of flavones. Glycosides are the predominant forms present. These most often are separated by reversed-phase HPLC on Cl8 columns with gradients consisting of acidified H20 and ACN, MeOH, or EtOH.

Autoignition of epoxy and phenolic composites with glass fiber, aramid and graphite was affected by the oxygen concentration to a limited degree. But with epoxy composites, neither fiber type nor concentration of oxygen had an effect on the autoignition time ( 50 s). In phenolic composites, the fiber type affected...

Some fruit and vegetables are stored under atmospheres enriched in CO2 and with reduced levels of O2. These storage conditions have a marked effect on phenolic metabolism and phenolic composition. Thus, Williams pears stored in air accumulate more phenol ics than fruits stored under controlled atmospheres (1% C02-l% O2 and 3% C02-3%02). A controlled atmosphere, then, strongly reduces the ability of pears to synthesise phenolic compounds [153].

Thermal characteristics are also important in numerous industrial processes, and thus the development of composites with high thermal conductivity and a low coefficient of thermal expansion is important to achieve effective heat conduction (Kim et al., 2007). The use of some reinforcements such as carbon nanotubes, carbon fibers, nano silica powders, metal particles, boron nitrite and glass fibers can improve the thermal conductivity of phenolic composites (Kim et al., 2007 Simitzis et al., 2011 Srikanth et al., 2010). Kim et al. (2007) demonstrated that the homogeneous dispersion of 7 wt% carbon nanotubes in a phenolic resin acted as an effective thermal bridge between adjacent carbon fibers and enhanced the thermal conductivity (393 W m-i K-i).
