“…Those compounds are also the major flavonols in the peels of ripe pears, as reported by others [2,28]. As the distinguished flavone in pears [30], the highest content of isorhamnetin-3- O -rutinoside (peak 78) was 143.8 μg/g FW in ‘Sanjili’, whereas the lowest was only 9.1 μg/g FW in ‘Xiangshuili’. Meanwhile, some other distinguished flavones were also found in different varieties.…”

“…Additionally, the debasing of both pomegranate and red grape juice with apple juice can be reliably detected through the determination of phloridzin, a flavonoid that has been identified as a typical apple juice marker [100]. 4- O -p-coumarylquinic acid has been reported as an apple juice unique compound that can reveal the addition of apple juice to pear juice while isorhamnetin-3- O -rutinoside, abscisic acid and arbutin were identified as characteristic pear compounds [101].…”

“…The concentration levels of these compounds were found to vary significantly among juices from China and juices from other countries, allowing also the geographical origin verification of pear juices [101]. Geographical origin and varietal discrimination of apple juices has also been achieved through the phenolic composition determination combined with statistical data evaluation techniques.…”

“…Discovery of substances, which should not be present in authentic juice or contained in it in small quantities, gives possibility to detect falsification of juices without detailed research. These substances include, in particular, the content of D-optical isomers of amino acids [15], starch hydrolysis products, synthetic dyes, aromatic substances and D-malic acid [12,16]. However, the mentioned study is ineffective in the case of using for falsification of pure and modified substances.…”
