                <text>Influences of matrix particle size distribution (PSD) (18, 25, 35 and 50 lm) and fat content (25%, 30% and 35%) on flavour release of dark chocolate volatiles were quantified by static headspace gas chromatography using GC–MS. Sixty-eight (68) flavour compounds were identified, comprising alcohols, aldehydes, esters, ketones, furans, pyrans, pyrazines, pyridines, pyroles, phenols, pyrones and thiozoles. From GC– olfactometry, 2-methylpropanal, 2-methylbutanal and 3-methylbutanal had chocolate notes. With cocoa/roasted/nutty notes were trimethyl-, tetramethyl-, 2,3-dimethyl-, 2,5-dimethyl-, 3(or 2),5- dimethyl-2(or 3)-ethyl- and 3,5(or 6)-diethyl-2-methylpyrazine and furfuralpyrrole. Compounds with fruity/floral notes included 3,7-dimethyl-1,6-octadien-3-ol and 5-ethenyltetrahydro-R,R,5-trimethylcis- 2-furanmethanol. Caramel-like, sweet and honey notes were conferred by 2-phenylethanol, phenylacetaldehyde …</text>

                <text>This paper investigates the relationship between board structure characteristics and financial performance of Listed Food and Beverage Firms (LFBFs) in Ghana. The study relied on published financial reports of LFBFs for the period of 2001 to 2013. To achieve the objective of the study, we estimated a linear regression model based on panel data which was performed on the dependent variable, return on assets (ROA). Through statistical calculations, we found evidence that board size and Chief Executive Officer duality have significant negative relationships with return on assets, with board composition having insignificant negative relationship with return on assets. However, a significant positive relationship was established between board ownership and return on assets. The study recommends that LFBFs in Ghana should consider having the right mix of experience and skills on the board, but not necessarily considering only a small or large board size. Also, shareholders should encourage board members to own shares in their firms and the few firms practicing CEO duality should work hard to reverse the practice completely.</text>

                <text>The typical flavour characteristics of cocoa are related to the cocoa bean genotype and the growing environmental conditions. However, the flavour does not exist in freshly harvested beans. Flavour is generated by a series of procedures that begins with occasional pod storage (PS) after harvesting, followed by fermentation of the beans, and roasting. PS implies storing harvested cocoa pods for a period of time before opening. The effect of PS is believed to be beneficial for the subsequent development of cocoa flavour in the cocoa beans [1]. During roasting, several volatile heterocyclic compounds are formed, among them alkylpyrazines. These newly formed compounds are considered to be key odour components. Among alkylpyrazines, tetramethylpyrazine and trimethylpyrazine, are the most abundant ones. Other alkylpyrazines with different substituents also contribute to the aroma profile. Hence, monitoring pyrazines can be helpful in optimizing roasting conditions of cocoa beans for attaining the desired aroma of the cocoa liquors. In several studies, cocoa volatiles have been measured using gas chromatography mass spectrometry (GC-MS), frequently using headspace solid-phase microextraction (HS-SPME) to concentrate the volatiles.&#13;
The purpose of this study was to investigate the effect of PS (0, 3, 7 days PS) and roasting temperature (100 C, 120 C, 140 C and 160 C) on the formation of alkylpyrazines in Ghanaian cocoa liquors. HS-SPME extraction of the alkylpyrazines was carried out with a DVB/CAR/PDMS fibre. The identified compounds were measured semiquantitatively and the results were statistically processed by multivariate …</text>

The proximate composition and acceptability of products using a 7-point hedonic scale were evaluated. With the addition of 30% cowpea, the protein content of the Kaklo from the firm ripe and soft ripe plantain increased from 2.92% to 7.32% and 3.65% to 8.05% respectively, whilst the protein of the Ofam from the firm and soft ripe plantain also increased from 3.80% to 8.45% and 3.75% to 8.15% respectively.
