Title A name given to the resource Variability in Biochemical Composition and Cell Wall Constituents among Seven Varieties in Ghanaian Yam (Dioscorea sp) Germpalsme Creator An entity primarily responsible for making the resource EO Afoakwa, D Polycarp, AS Budu, H Mensah-Brown, E Otoo Description An account of the resource This work characterized the most cultivated and consumed yam (Dioscorea) cultivars within the Ghanaian yam germplasm based on their biochemical and cell wall constituents to assess their potential alternative food and industrial processing applications. Samples were analyzed for their biochemical composition-starch, amylose, amylopectin, total sugars, reducing sugars and non-reducing sugars along the head, middle and tail regions of each tuber using standard analytical methods. Cell wall constituents-acid detergent fibre, neutral detergent fibre, acid detergent lignin, cellulose and hemicellulose of each tuber were also determined using standard analytical methods. The results showed no significant differences at p< 0.05 in biochemical compositions along the length of the studied cultivars. D. cayenensis (Pure-yellow), D. rotundata (Pona) and D. alata (Matches) were found to have high starch contents (63.16-65.69%, 63.54-65.30% and 63.24-65.17% respectively). Amylose content was observed to vary along the length of the tubers for the varieties studied. D. alata (Matches) was observed to contain the highest amylose content of 19.66-20.64%. No identifiable trend was however, observed for the amylopectin content along the length between the varieties investigated. D. bulbifera recorded the lowest amylopectin content of 41.29%, 43.59% and 44.63% while D. esculenta had the highest with 49.84%, 50.24% and 50.13% along the tail, middle and head sections respectively. Total sugar content varied significantly (p< 0.05) along the lengths of all the varieties investigated. It was higher at the tail portions for all the varieties studied than the … Date A point or period of time associated with an event in the lifecycle of the resource 2013 Source A related resource from which the described resource is derived https://scholar.google.com/citations?view_op=view_citation&hl=en&user=EZuX1N8AAAAJ&cstart=20&pagesize=80&citation_for_view=EZuX1N8AAAAJ:kRWSkSYxWN8C Language A language of the resource English Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource Chocolate and cocoa, flavor and quality Creator An entity primarily responsible for making the resource Emmanuel Ohene Afoakwa Description An account of the resource Cocoa is the fundamental ingredient in chocolate manufacture and is derived from the fruit of the cocoa tree. Variations in cocoa bean genotype exhibit distinct differences in flavor characteristics during subsequent processing of the beans into cocoa liquor. These chocolate characteristics not only originate in flavor precursors present in cocoa beans, but also they are generated during post‐harvest treatments and transformed into desirable odor notes in the manufacturing processes. Complex biochemical modifications of bean constituents are further altered by thermal reactions in roasting and conching and in alkalization. However, the extent to which the inherent bean constituents from the cocoa genotype, environmental factors, post‐harvest treatment, and processing technologies influence chocolate flavor formation and relationships with final chocolate flavor quality requires more in‐depth understanding.

Title A name given to the resource Nutrition and food Creator An entity primarily responsible for making the resource Emmanuel Ohene Afoakwa, Agnes Simpson Budu, Clement Asiedu, Linley Chiwona-Karltun, Drinah B Nyirenda Description An account of the resource High yielding and cassava mosaic disease (CMD) resistant cassava varieties have been developed by the Crop Research Institute of Ghana with varying compositions and concentrations of starches and sugars. This study characterized four of these improved cassava varieties (Ampong, Broni bankye, Sika and Otuhia) together with two traditional varieties (Amakuma and Bankye fitaa) for their composition of starches and sugars using principal component and cluster analyses. The concentration of total sugars, reducing and non-reducing sugars, sucrose, starches, amylose and amylopectin were determined using standard analytical methods. Results obtained were total sugar (4.04-18.47%), non-reducing sugar (2.08-16.21%), sucrose (1.98-15.40%), starch (15.39-31.07%) and amylose (30.57-40.33%) and these were significantly different (p< 0.05) amongst the studied cassava varieties. The improved varieties (Ampong, Broni bankye, Sika and Otuhia) had high total sugar levels ranging from 7.19 to 18.47%. With the exception of Broni bankye (improved variety) all the improved and traditional varieties were high starch and amylose containing varieties. These differences in the biochemical composition of the traditional and improved cassava varieties could be used in their selection for specific food and industrial processing applications.

Title A name given to the resource Comparing flavor profiles of dark chocolates refined with melanger and conched with Stephan mixer in various alternative chocolate production techniques Creator An entity primarily responsible for making the resource Michael Hinneh, Davy Van de Walle, Daylan Amelia Tzompa-Sosa, Julie Haeck, Enoch Enorkplim Abotsi, Ann De Winne, Kathy Messens, Jim Van Durme, Emmanuel Ohene Afoakwa, Luc De Cooman, Koen Dewettinck Description An account of the resource The use of alternative equipment for chocolate production is gaining attention in recent times in many countries. This is due to the lower cost of investment and maintenance, multi-functionality, and lower throughput. This study was conducted to investigate the applicability of two of such equipment; melanger and Stephan mixer. In the first set-up, the possibility of refining chocolate with the melanger in comparison with the conventional 3-roll refiner was explored. Whereas in the second set-up, the applicability of the Stephan mixer (aided with a vacuum pump) for a conching-like application was also investigated. From each set-up, 70% dark chocolates produced through various alternative means were then evaluated on the basis of their flavor profiles. Specific groups of volatiles such as aldehydes, ketones, terpenes and terpenoids, showed significant (p < 0.05) differences due to the different refining … Publisher An entity responsible for making the resource available Springer Berlin Heidelberg Date A point or period of time associated with an event in the lifecycle of the resource 2019 Source A related resource from which the described resource is derived https://scholar.google.com/citations?view_op=view_citation&hl=en&user=EZuX1N8AAAAJ&cstart=80&citation_for_view=EZuX1N8AAAAJ:PQ6BjWB6CiEC Language A language of the resource English https://repository.gctu.edu.gh/files/original/9f265df8a4031855de5ce63b1a4489cc.pdf 26128ffe5069d7a0130a277da1b4801b Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Variations in chemical composition and physico-chemical properties of 10-soy-peanut-cow milk (SPCM) formulations were studied. Variations in soy-peanut-cow milk (SPCM) concentrations influenced to varying levels the chemical composition and physico-chemical properties of blends. SPCM formulations containing significant amounts of all three ingredients used (60-70% soy milk, 20-27% peanut milk and 7-20% cow milk) had high crude protein and fat values ranging from 2.20-2.51% and 5.00-6.35% respectively. Increasing soy concentrations caused relative increases in protein content while fat content increased with increasing peanut concentrations. SPCM formulations were high in the minerals Fe and Mn relative to cow milk which was high in Ca and Zn content. Trends in pH were contrary to titratable acidity and increased with increasing soy milk content but decreasing cow milk content. SPCM formulations demonstrated acceptable non-Newtonian behaviour and consistency indices.

Title A name given to the resource Effect of roasting conditions on the browning index and appearance properties of pulp pre-conditioned and fermented cocoa (Theobroma Cacao) beans Creator An entity primarily responsible for making the resource Emmanuel Ohene Afoakwa, Agnes Simpson Budu, Henry Mensah-Brown, JF Takrama, E Ofosu-Ansah Description An account of the resource Appearance is an important quality determinant of cocoa beans and it is used as standard criteria to establish the degree of fermentation and drying of the beans. Changes in browning index and colour (L* a* b*) during roasting of pulp pre-conditioned and fermented cocoa beans were studied using standard analytical methods. Increasing pod storage and roasting time at 120oC led to variable increases in browning index (BI) and b*-values of the beans with decreases in the L* and a* values. Cocoa pod stored for 10 days showed the highest BI (1.144) with the least L* value (24.15) whilst beans from the unstored pods showed the least BI (1.007) with the highest L* value (25.55). The rates of change in BI and colour (L*, a*, b*) were however more pronounced during roasting than pod storage. Brown pigment formation (BI) and the L* value were more pronounced after 30 minutes of roasting in beans from pods stored for 3 to 7 days. The colour changes in beans from 10 days pod storage was significant (p< 0.05) after 45 minutes of roasting. The beans from the pods stored for 3 to 7 days showed consistent decrease in L* and a* values with increasing roasting time whiles the beans from the 10 days of pod storage were observed to produce lower L* value (darker beans) after 45 minutes of roasting. Pod storage between 3 to 7 days could be used to improve the brownness and appearance of roasted cocoa nibs. Beans from cocoa pod stored between 3 to 7 days produced the most acceptable BI and L* value after roasting for 30 minutes at 120oC.
