This report describes the characterization of a series of commercially available procyanidin standards ranging from dimers DP = 2 to decamers DP = 10 for the determination of procyanidins from cocoa and chocolate. Using a combination of HPLC with fluorescence detection and MALDI-TOF mass spectrometry, the purity of each standard was determined and these data were used to determine relative resp...

trans-Resveratrol and trans-piceid were found for the first time in dark chocolate (at least 0.4 ppm trans-resveratrol and 1 ppm trans-piceid) and cocoa liquor (at least 0.5 ppm trans-resveratrol and 1.2 ppm trans-piceid). Because these compounds are highly sensitive to light, a specific extraction procedure was required to recover them, involving delipidation with toluene and cyclohexane and e...

Artificial Neural Networks (ANNs) have been implemented in almost every field, viz., science, technology, medicine and engineering as they have proved useful tools for obtaining the desired output including the analyses and shelf life prediction in case of food products. This review discusses the systematic information available in the literature concerning the implementation of ANN models for ...

We propose that the horizontal and vertical position of an item on a display is a source of information that individuals use to make judgments. Six experiments using 1 × 5 or 5 × 5 displays show that consumers judge that products placed at the bottom (vs. top) and on the left-hand (vs. middle and right-hand) side of a display are less expensive and of lower quality (Study 1a using a bar display...

Current psychological theory and research affirm the positive affective and motivational consequences of having personal choice. These findings have led to the popular notion that the more choice, the better-that the human ability to manage, and the human desire for, choice is unlimited. Findings from 3 experimental studies starkly challenge this implicit assumption that having more choices is ...

A study to determine the total content of phenolic compounds, flavonoids and mass fraction iodine in chocolate using non-traditional raw materials has been conducted. The object was products, containing stevioside, erythrol, germinated soy flour, enriched with iodine.
 Carrying out this set studies is important because it will developed chocolate. Based on obtained patterns, possible perce...
