“…Dry matter content was highest (93.55%) in the roasted meal and least (89.71%) in the raw undehulled meal. The highest value in the roasted meal could be due to heat treatment from roasting which reduced the seeds' moisture content and this indicates that they can be stored for a long time and will be less prone to microbial attack during storage (Udo et al, 2016). Crude protein content was highest (45.31%) in the solventextracted meal and least (27.02%) in the raw undehulledmeal.…”

Over-exploitation of conventional protein-rich plant resources such as soybean and groundnut for human and livestock consumption has necessitated a search for other suitable and under-utilized alternatives such as sunflower (Helianthus annuus) seeds. This study was undertaken to investigate the effect of processing on the proximate composition of sunflower seeds. The processing methods employed were boiling, roasting, solvent extraction and mechanical extraction. There was a substantial recovery of crude protein after processing from 27.02% (in the raw undehulled sunflower seed sample) to values ranging from 32.21% to 45.31% in the dehulled and differently processed samples. Crude lipid ranged from 6.45 to 21.60%, nitrogenfree extract from 11.32 to 19.52%, moisture content from 6.44to 10.29%, crude fibre from 14.19 to 26.35% and ash content from 4.61 to 5.46%. Values of the above proximate parameters were observed to be statistically different (p < 0.05) between the raw and differently processed sunflower seed samples. The results showed that the processing methods employed had improved the nutritional value of sunflower seed. Therefore, in view of its considerably high crude protein content, the study recommends sunflower seed meal as a viable alternative to expensive and over-utilized soybean meal and groundnut cake in feed formulation for fish and livestock.

“…35,36,37 For macro minerals (K, Ca, P and Mg), soaked Caladium bicolor meal has a value which differed significantly (P<0.05) from boiled C bicolor meal: implying that when used in feeding trials would enhance good neural conduction and muscular contraction, blood coagulation, bone and teeth formation, better membrane function and carbohydrate metabolism. 38,13,29 Micro minerals result followed trend of macro minerals in that the tuberous roots processed by soaking had the superior value for Mn, Cu, Zn and Fe. This implies that using soaked tuberous root as ingredient in animal diet would enhance blood formation (because of high value of iron), normal utilization of carbohydrate by livestock/ poultry animals (because manganese serves as a co-factor to enzymes responsible for carbohydrate metabolism such as kinase, decarboxylase, peptidase); enhanced zinc promotion for healing of wounds and also favour good taste, appetite and growth, provide copper as a component of cytochrome oxidase, which is important in oxidative phosphorylation.…”

“…9 The values of CF in this study was lower than CF of conventional feedstuffs like soybean meal and groundnut cake with 6.5 and 5% crude fibre, respectively, but comparable with conventional feedstuffs such as maize and guinea corn with 2.0% crude fibre, respectively. 28,29 Fibre has some nutritional and health benefits in human/ livestock nutrition especially in gastro-intestinal tract by reducing gastric emptying time in the small intestine, enhancing bile salt and cholesterol excretion, increasing faecal bulk and faecal transit time through the bowl. 30,31 The values of fibre obtained for raw and processed tubers tend to be advantageous to monogastric animals especially poultry, knowing fully that they have low ability to handle fibrous materials.…”

Nutrient Composition, Mineral and Anti-Nutrient Components of Processed Wild Cocoyam (Caladium Bicolor, (Ait) Vent)

In the subtropic and perhaps worldwide a novel plant Caladium bicolor (wild cocoyam, Ikpong Ekpo) has not actually been utilized as food for man, livestock or poultry, though in abundance. Also, the effective utilization of wild cocoyam (Caladium bicolor) tubers in livestock and poultry feed is limited by the presence of anti-nutrient components which requires some form of processing. The effect of boiling and soaking on gross energy, mineral composition, anti-nutritional factors (ANFs) and proximate composition of wild cocoyam (Caladium bicolor (Ait), Vent) were determined with the aim of investigating its suitability as a feed ingredient. The soaked, raw and boiled tubers were dried, milled and analyzed for chemical compositions. Crude protein contents of raw and processed Caladium bicolor tubers range were 7.58% - 8.28% and the crude fibre values ranged between1.92 - 2.12%. The gross energy value of boiled Caladium bicolor tubers was higher (2.85kcal/g) and also statistically similar (p>0.05) to both raw and soaked Caladium bicolor tubers. The micro and macro mineral composition of boiled Caladium bicolor tubers was significantly (p<0.05) lower compared to soaking method. Values obtained for boiled Caladium bicolor tubers were significantly (p<0.05) lower in all the toxic substances determined, except for the HCN content being above the tolerable limit for ruminant animals. The results indicate that processing techniques adopted enhanced the proximate composition, caloric components, mineral contents and significantly (p>0.05) lowered in the level of anti-nutrients present in wild cocoyam (Caladium bicolor (Ait). Vent) tubers with boiling being the best and hence the recommended processing method for use in detoxifying C. bicolor.

“…Differences in cyanide contents of meals, higher for hexane extraction than ethanol, could be due to a partial removal of cyanogenic glycoside (called linamarin). Since linamarin is a water soluble compound [42], it could be partly removed by a polar solvent like ethanol during RSO extraction.…”

In the latex production chain, rubber tree seeds (Hevea brasiliensis) represent an underutilized fraction with high potentialities, which can increase the sustainability of the whole process if rightly valorized. In the present study, the quality of all the fractions obtained from the rubber fruit were evaluated, with the aim to identify possible applications for their valorization with a circular economy perspective. Seeds from five different varieties of rubber tree were analyzed. Furthermore, a whole mass and energy balance was defined, which has allowed us to define hypothetical production scenarios. The obtained results show negligible differences among varieties. Shells and capsules have shown a composition similar to woody biomass, with high heating values (more than 16.5 MJ kg−1), low nitrogen content (below 0.5% on weight basis (w/w)) and reduced ash content (0.51% w/w and 1.90% w/w, respectively). Kernels were chemically extracted comparing two different solvents: n-hexane and ethanol. Both solvents showed similar extraction yields, i.e., 49% w/w and 46% w/w for n-hexane and ethanol, respectively. The resulting extraction flour was characterized by a high protein content (around 40% w/w) making it suitable for animal feeding. The rubber seed oil could be used in blends of different vegetable oils for biodiesel production. All this information is useful for improving the sustainability of the latex production chain and to assess the sustainability of possible bioenergy value chains.
