Apart from this production performance, the quality of the beans, which are mainly exported to the major chocolate-making countries, presents a quality problem to the point of suffering a discount on the international market. One of these quality problems is the content of ochratoxin A, a mycotoxin produced by fungi. Finally, to verify the level of contamination in beans produced in Côte d’Ivoire, a study was carried out. It consisted of collecting information on fermentation and drying times (The two major post-harvest operations) and collecting beans, which were analyzed by electrophoresis using the High Performance Liquid Chromatography (HPLC) method. The results obtained show ochratoxin A contents of between 0.05 µg/kg and 0.17 µg/kg. The general level of contamination is therefore very low and below the tolerable limit which is 2 µg/kg. In addition, the correlative study between the fermentation and drying times of the beans revealed no significant influence (p < 0.01) of the duration of these operations on the level of ochratoxin A contamination. Major contamination can occur after post-harvest activities carried out by producers. This is certainly due to the development of fungi responsible for the production of ochratoxin A during the period of storage and marketing of cocoa beans in conditions of high humidity in storage enclosures. Producers need to be made more aware of the need to ensure that cocoa beans are properly dried and stored in dry areas to avoid moisture build-up, which is a source of mould growth and ochratoxin A production.展开更多

The results show that variation of stress increases nonlinearly and residual oil rate decreases with the increase of compression ratio. Lower residual oil of cake was obtained by pressing gently and frequently. Curve fitting on both relationships had been built and parameters for the model were obtained by least square procedure and deepening research on pressing process of the castor beans for castor oil. By assuming that the value of oil production is equivalent to the value of energy consumption, the critical compression ratio of intact seeds is 6.2 while that of crushed seeds is 3.6.展开更多

Black bean seeds were dehulled both manually and mechanically and the flours obtained from the dehulled seeds were compared with flour milled from undehulled seeds. The flours obtained were evaluated for proximate composition, physical and pasting properties. Anti-nutritional factors in the flours were also determined. The flours were then used to prepare steamed bean cake (“Moinmoin”) which was evaluated for sensory parameters of appearance, taste, aroma, texture and overall acceptability. Dehulling produced significant effects (p 0.05 and p > 0.01) prepared from dehulled flours, but there was significant difference (p < 0.05) at both levels in most sensory parameters between samples from dehulled seeds and undehulled seeds except for aroma.展开更多

Water absorption was increased by addition of bean flour as a result of increase rate of substitution. Dough stability decreased for bean and sorghum blends as the same as increasing addition. Softening gradually increased with increasing the addition of beans or sorghum. Addition of 15% sorghum had the highest degree of softening compared with wheat control and beans mixtures. The extensibility, elasticity and the energy of produced dough were decreased with addition of beans or sorghum to wheat flour and the reduction increased with increasing the level of substitution. In contrast, addition of beans or sorghum to wheat flour increased the proportional number of the produced dough from 3.25 to 3.62 and from 1.80 to 2.90 for beans and sorghum dough, respectively. Bread supplemented with beans had the highest values in protein, ash and fiber compared with wheat and sorghum bread whereas, bread supplemented with sorghum had the highest values in fat content compared with wheat and beans bread. Sorghum bread had the highest iron and zinc content while beans bread had the highest calcium content. The sensory evaluation showed that different blends of beans and sorghum bread had highly acceptable values of all characteristics comparing with wheat control bread. Freshness of all unleavened flat bread blends decreased at different periods as well as bread control compared with zero time period. Water holding capacity (WHC) was significantly increased in all samples compared with wheat bread. Supplementation of bread with 15% beans recorded the highest value in WHC.展开更多

Total phenols, flavonoids and free radical scavenging capacity were determined by colorimetric methods. Furthermore, qualitative flavonoid characterization was performed via HPLC diode array. The acetic acid extract contained 73.4 ± 7 mg/g of sample expressed as gallic acid equivalents (GAE), and 41.3 ± 4 mg/g as catechin equivalents (CE). The acetic acid extract (at 1 mg/mL) showed over 89% efficiency to scavenge the 1,1 diphenyl-2-picrylhydrazil (DPPH) radical (EC50 = 6.13 mg extract/mg standard). Gallic acid, delphinidin-3-glycoside, petunidinglycoside, petunidin, malvidin-3-glycoside, myricetin-glycoside, quercitin-glycoside, saponin (β-g), and 3-hydroxy-5, 7-megastigmadien-9-one were identified in both extracts. Additionally, kaempferol-3-glycoside was found in the acetic acid extract. Sequential acetic acid extractions indicated that the antiradical activity was about 90% in DPPH radical scavenging within the first 8 h of extraction, when compared to a 24 h extraction. In general, acetic acid offered a faster and more efficient approach for the extraction of展开更多

Many consumers are unfamiliar with dried beans or do not have the time to prepare them. The purpose of this study was to compare nutrient density and nutrient-to-cost among dried cooked, canned (liquid and solids), and canned/drained black, garbanzo, kidney, lima, pinto, white beans, and black-eyed peas. Prices were obtained from 60 grocery stores in January 2009. Nutrient content per 100 g was calculated using the U.S. Department of Agriculture Nutrient Database for Standard Reference, Release 22, and Nutrition Data System for Research (for canned/drained). Nutrient density scores were estimated using the Nutrient Rich Food Index 9.3 (NRF9.3). Nutrient-to-cost ratio (NTCR) was computed as the NRF 9.3 score (per 100 kcal) divided by the cost per half-cup servings per package (12) or per can (3.5). Compared to canned beans, dried cooked beans were significantly more energy dense, contained more protein, fiber, iron, potassium and magnesium;and less sodium than canned beans (p < 0.05 for all). Canned/drained beans contained more sodium than cooked beans (p < 0.05). NRF9.3 scores were 7.3, 2.8, and 4.8 for cooked, canned, and canned/drained beans, respectively. NTCR for cooked, canned, and canned/drained beans was 63.4, 8.9, and 15.2, respectively. Results highlight the benefits of choosing dried beans and also illustrate that canned beans, when drained, provide a healthy alternative. Beans, regardless of type/form, are a nutrient rich food and should be encouraged as part of an overall healthy diet.展开更多
文摘Côte d’Ivoire has been the world’s leading producer of cocoa beans for several decades. Apart from this production performance, the quality of the beans, which are mainly exported to the major chocolate-making countries, presents a quality problem to the point of suffering a discount on the international market. One of these quality problems is the content of ochratoxin A, a mycotoxin produced by fungi. Finally, to verify the level of contamination in beans produced in Côte d’Ivoire, a study was carried out. It consisted of collecting information on fermentation and drying times (The two major post-harvest operations) and collecting beans, which were analyzed by electrophoresis using the High Performance Liquid Chromatography (HPLC) method. The results obtained show ochratoxin A contents of between 0.05 µg/kg and 0.17 µg/kg. The general level of contamination is therefore very low and below the tolerable limit which is 2 µg/kg. In addition, the correlative study between the fermentation and drying times of the beans revealed no significant influence (p < 0.01) of the duration of these operations on the level of ochratoxin A contamination. Major contamination can occur after post-harvest activities carried out by producers. This is certainly due to the development of fungi responsible for the production of ochratoxin A during the period of storage and marketing of cocoa beans in conditions of high humidity in storage enclosures. Producers need to be made more aware of the need to ensure that cocoa beans are properly dried and stored in dry areas to avoid moisture build-up, which is a source of mould growth and ochratoxin A production.

文摘The relationships among compression ratio and stress, compression ratio and residual oil of cake in pressing process of castor beans were studied using the test equipment under different states of oilseeds and ways of pressing manners. The results show that variation of stress increases nonlinearly and residual oil rate decreases with the increase of compression ratio. Lower residual oil of cake was obtained by pressing gently and frequently. Curve fitting on both relationships had been built and parameters for the model were obtained by least square procedure and deepening research on pressing process of the castor beans for castor oil. By assuming that the value of oil production is equivalent to the value of energy consumption, the critical compression ratio of intact seeds is 6.2 while that of crushed seeds is 3.6.

文摘The effects of dehulling on the physico-chemical and pasting of, as well as anti-nutritional factors in black bean (Phasoelus vulgaris) flours were investigated. Black bean seeds were dehulled both manually and mechanically and the flours obtained from the dehulled seeds were compared with flour milled from undehulled seeds. The flours obtained were evaluated for proximate composition, physical and pasting properties. Anti-nutritional factors in the flours were also determined. The flours were then used to prepare steamed bean cake (“Moinmoin”) which was evaluated for sensory parameters of appearance, taste, aroma, texture and overall acceptability. Dehulling produced significant effects (p 0.05 and p > 0.01) prepared from dehulled flours, but there was significant difference (p < 0.05) at both levels in most sensory parameters between samples from dehulled seeds and undehulled seeds except for aroma.

文摘The present study was carried out to develop the wheat flour nutritional value with good quality of unleavened bread by adding 5%, 10% and 15% of bean or sorghum flour. Water absorption was increased by addition of bean flour as a result of increase rate of substitution. Dough stability decreased for bean and sorghum blends as the same as increasing addition. Softening gradually increased with increasing the addition of beans or sorghum. Addition of 15% sorghum had the highest degree of softening compared with wheat control and beans mixtures. The extensibility, elasticity and the energy of produced dough were decreased with addition of beans or sorghum to wheat flour and the reduction increased with increasing the level of substitution. In contrast, addition of beans or sorghum to wheat flour increased the proportional number of the produced dough from 3.25 to 3.62 and from 1.80 to 2.90 for beans and sorghum dough, respectively. Bread supplemented with beans had the highest values in protein, ash and fiber compared with wheat and sorghum bread whereas, bread supplemented with sorghum had the highest values in fat content compared with wheat and beans bread. Sorghum bread had the highest iron and zinc content while beans bread had the highest calcium content. The sensory evaluation showed that different blends of beans and sorghum bread had highly acceptable values of all characteristics comparing with wheat control bread. Freshness of all unleavened flat bread blends decreased at different periods as well as bread control compared with zero time period. Water holding capacity (WHC) was significantly increased in all samples compared with wheat bread. Supplementation of bread with 15% beans recorded the highest value in WHC.

文摘Extraction of phenolic compounds from bean seed coats by acetic acid was evaluated and compared to conventional extraction with 80% methanol. Total phenols, flavonoids and free radical scavenging capacity were determined by colorimetric methods. Furthermore, qualitative flavonoid characterization was performed via HPLC diode array. The acetic acid extract contained 73.4 ± 7 mg/g of sample expressed as gallic acid equivalents (GAE), and 41.3 ± 4 mg/g as catechin equivalents (CE). The acetic acid extract (at 1 mg/mL) showed over 89% efficiency to scavenge the 1,1 diphenyl-2-picrylhydrazil (DPPH) radical (EC50 = 6.13 mg extract/mg standard). Gallic acid, delphinidin-3-glycoside, petunidinglycoside, petunidin, malvidin-3-glycoside, myricetin-glycoside, quercitin-glycoside, saponin (β-g), and 3-hydroxy-5, 7-megastigmadien-9-one were identified in both extracts. Additionally, kaempferol-3-glycoside was found in the acetic acid extract. Sequential acetic acid extractions indicated that the antiradical activity was about 90% in DPPH radical scavenging within the first 8 h of extraction, when compared to a 24 h extraction. In general, acetic acid offered a faster and more efficient approach for the extraction of
文摘Consumption of nutrient rich foods such as beans and peas is recommended because these foods provide key nutrients and relatively little energy. Many consumers are unfamiliar with dried beans or do not have the time to prepare them. The purpose of this study was to compare nutrient density and nutrient-to-cost among dried cooked, canned (liquid and solids), and canned/drained black, garbanzo, kidney, lima, pinto, white beans, and black-eyed peas. Prices were obtained from 60 grocery stores in January 2009. Nutrient content per 100 g was calculated using the U.S. Department of Agriculture Nutrient Database for Standard Reference, Release 22, and Nutrition Data System for Research (for canned/drained). Nutrient density scores were estimated using the Nutrient Rich Food Index 9.3 (NRF9.3). Nutrient-to-cost ratio (NTCR) was computed as the NRF 9.3 score (per 100 kcal) divided by the cost per half-cup servings per package (12) or per can (3.5). Compared to canned beans, dried cooked beans were significantly more energy dense, contained more protein, fiber, iron, potassium and magnesium;and less sodium than canned beans (p < 0.05 for all). Canned/drained beans contained more sodium than cooked beans (p < 0.05). NRF9.3 scores were 7.3, 2.8, and 4.8 for cooked, canned, and canned/drained beans, respectively. NTCR for cooked, canned, and canned/drained beans was 63.4, 8.9, and 15.2, respectively. Results highlight the benefits of choosing dried beans and also illustrate that canned beans, when drained, provide a healthy alternative. Beans, regardless of type/form, are a nutrient rich food and should be encouraged as part of an overall healthy diet.
