Study of the nutritional value of black cumin seeds (Nigella sativaL)

The nutritional value of five samples of black cumin seeds from five different sources available in the local market were studied. The average values of the proximate analysis on dry matter basis were 216 g kg⁻¹ for crude protein, 406 g fat, 45 g ash, 84 g crude fibre and 249 g of nitrogen-free extract, whereas moisture content was 38 g kg⁻¹. The mineral and vitamin analyses showed that black cumin seeds contained iron, (105 mg kg⁻¹) copper (18 mg), zinc (60 mg) phosphorus (527 mg), calcium (1860 mg), thiamin (15·4 mg), niacin (57 mg), pyridoxine (5·0 mg) and folic acid (160 μg). The protein quality of black cumin seeds was evaluated using net protein utilisation (NPU), protein efficiency ratio (PER) and net dietary protein energy percent (NDPE %) for two samples imported from Syria and Turkey, while PER was determined for the Syrian sample only. The results indicated that the NPU standardised of Turkish black cumin seeds was significantly higher than that of Syrian type (P<0·05). The mean results (±SD) were 54·6±2·72 for the Syrian type and 63·1±3·74 for the Turkish type. The NDPE% mean results (±SD) were 5·3±0·79 and 5·6±0·26 for the Syrian and the Turkish samples, respectively. The PER adjusted value for the Syrian samples was 1·9. The results of protein quality evaluation and those of the nutrient composition suggest that black cumin is of relatively good nutritional value. © 1998 SCI.     

Evaluation of Phenolic Content,Antioxidant Activity,and Nutritional Composition of Cordia evolutior (Clarke) Gamble

The objectives of this study were to determine phenolic content, antioxidant activity of methanolic extracts from different parts of Cordia evolutior (leaf, bark, and fruit), and nutrition composition. The leaf extract showed the highest total phenolic content (25.40 ± 0.34 mg GAE/g extract) and total flavonoid content (69.70 ± 3.37mg RE/g extract) accompanied with the best antioxidant activity through all antioxidant assays. The fruit proximate compositions of crude protein, ash, carbohydrate, fiber, and fat were analyzed. Macro-nutrient contents were found to be higher in the fruit when compared to micronutrients. The analysis also showed the presence of almost all of the essential and non-essential amino acids. Linolenic acid content was higher than stearic acid among the fatty acids in the fruit.     

CHEMICAL COMPOSITION AND NUTRITIONAL POTENTIAL OF VIGNA UNGUICULATA SSP. CYLINDRICA (FABACEAE)

Seeds of Vigna unguiculata (L.) Walp. ssp. cylindrica (L.) Estt. (Fabaceae) were analyzed for proximate composition, proteins, fatty acids, minerals, antinutritional factors and phytohaemagglutinating activity. Crude protein, crude fat, ash and nitrogen free extractives constitute 29, 10, 4 and 53%, respectively. The caloric value of 100 g dry matter of seed material was 1737 KJ. The essential amino acids, isoleucine, lysine and tyrosine+phenylalanine are present in higher concentrations as 124.3, 79.5 and 79.1 mg/100 g crude protein, respectively. The unsaturated fatty acids constituted more than 60% of total fatty acids. The seeds were found to be a potential source of minerals such as potassium, calcium, phosphorus, zinc and iron. The antinutritional factors such as total free phenols, tannins, L‐DOPA, hydrogen cyanide and phytic acid contents were determined. The effect of cooking on the levels of nutritional and antinutritional factors was also assayed. Cooking caused reduction of 0.02, 0.59 and 0.36% in the mineral constituents of potassium, calcium and phosphorus, respectively. More than 70% of the antinutritional factors were eliminated and there was an increase of crude fiber content.     

Chemical composition of Candida utilis and the biological quality of the yeast protein

The chemical composition (moisture, ash, protein and non-protein N, amino acids, ether extract, crude fibre, Ca, P, Fe) and biological quality (protein efficiency ratio and available lysine) were investigated in two batches of Candida utilis (Torula yeast). The samples (S₁ and S₂) were collected from a local factory. S₂ was sterilised before drying. Protein, mineral and B-complex vitamin contents were comparatively high. Amino-acid analysis showed a high content of lysine and threonine, but a deficiency in sulphur amino acids. The biological quality measured as the protein efficiency ratio (p.e.r.) and available lysine gave values of 1.80 ± 0.05 and 6.6 g/100g of crude protein, respectively, in S¹. These are higher than values reported in the literature. Sterilisation (S₂) and storage for 1 year (S_1(a)) significantly reduced the biological quality of the protein (p.e.r. 1.15 ± 0.12 and 1.34 ± 0.07, respectively). Supplementation of C. utilis with 0.3% DL -methionine increased the p.e.r. value to 2.77 ± 0.03, close to that of casein. C. utilis appears to be a valuable material for human diets because of the high content and satisfactory quality of its protein and other nutrients.     

Chemical composition and potential of some underutilized tropical biomass. I: fluted pumpkin (telfairia occidentalis)

The seeds of Telfairia occidentalis have been subjected to standard chemical analysis to evaluate their properties. Proximate analysis indicated a low moisture content (6.30 ± 0.50%). The ash content was slightly higher than the range recommended for compounding of animal feed (3.44 ± 0.06%). The carbohydrate content was low (16.5 ± 0.12%). Starch, however, constituted the dominant carbohydrate (62.5 ± 0.48), while three sugars, glucose, fructose and sucrose were detected in the seed. The crude protein in the seed was high (16.0 ± 0.03%), a value which compared favourably with high protein seeds and nuts. In all, 16 amino acids were detected in the protein. Glutamic acid showed the highest concentration (16.4 g 100 g⁻¹), while lysine showed the lowest (2.6 g 100 g⁻¹). The brown oil extracted from the seed (yield 48.6 ± 0.94) had the following physicochemical properties; acid value, 3.05 ± 0.80 g, saponification value 166 ± 1.34 mg/KOH g⁻¹, free fatty acids, 0.3 g and peroxide value 3.02 ± 0.07 mg Eq kg⁻¹. The iodine value (80.1 ± 0.10)g 100 g⁻¹ indicated a preponderance of unsaturated fatty acid. Four fatty acids were detected whilst unsaturated acids constituted 61.3 g. Triglyceride was the dominant lipid species while hydrocarbons, waxes, sterols and sterol esters and higher alcohols, were detected in the unsaponifable matter. Results of nutritionally valuable mineral elements indicated that potassium occurred at the highest concentration.     

PRODUCTION OF PALM OIL REFERENCE MATERIALS FOR THE DETERMINATION OF SOLID FAT CONTENT

ABSTRACT

Three palm oil reference materials were produced for solid fat content analysis employing the Malaysian Palm Oil Board (MPOB) Test Methods. Thirteen laboratories participated in the characterization study, where the solid fat content in palm oil, palm olein and palm stearin were identified at temperature range from 0 to 45C. The consensus values were calculated based on the acceptability of statistical results from collaborating laboratories. Both of the consensus values and their uncertainties (%) for each reference material are as follows: 71.12 ± 1.82% (0C), 54.07 ± 1.05% (10C), 37.44 ± 0.88% (15C), 24.18 ± 1.09% (20C), 13.32 ± 0.86% (25C), 7.64 ± 0.28% (30C), 4.05 ± 0.14% (35C) and 1.25 ± 0.49% (40C) for SFC of palm oil, 66.32 ± 1.93% (0C), 43.53 ± 1.32% (10C), 22.50 ± 0.78% (15C), 6.68 ± 1.14% (20C) and 1.40 ± 0.35% (25C) for SFC of palm olein, and 78.09 ± 1.23% (0C), 67.66 ± 0.71% (10C), 56.29 ± 1.18% (15C), 44.37 ± 1.13% (20C), 30.22 ± 1.25% (25C), 20.08 ± 0.58% (30C), 13.72 ± 0.32% (35C), 8.97 ± 0.72% (40C) and 5.06 ± 0.41% (45C) for solid fat content of palm stearin.

PRACTICAL APPLICATIONS

The implementation of the ISO 17025 accreditation should be encouraged for testing laboratories to assure the traceability of analysis performed. This accreditation requires the use of certified reference materials to ensure that the analysis performed is parallel to the ISO 17025 standards. However, the unavailability of palm oil reference materials will affect the implementation of such standards for laboratories that are performing palm oil analyses. Hence, this study is aimed to characterize and certify the palm oil reference materials for determination of solid fat content. The establishment of this study is hoped to increase the credibility of laboratories, which are involved in the palm oil analysis. This will also promote the Malaysia Palm Oil Board as a center for the certification of palm oil reference materials.     

Composition and nutritional evaluation of Aspergillus oryzae biomass grown on palm oil processing effluents

Aspergillus oryzae biomass grown on effluents produced during the extraction of palm oil was found to have a crude protein content of 39.6 g 100 g^?1 and a ‘true protein’ content of 32.1 g 100 g^?1. Amino acid analysis showed that the essential amino acid content was 58.2 g 16 g^?1 N and the essential amino acid index was calculated to be 87.4. The sulphur-containing amino acids were present at a combined level of 2.8 g 16 g^?1. In rat feeding trials the biomass had a biological value of 0.68 ± 0.03, a net protein utilisation of 0.65 ± 0.05 and a true digestibility of 0.96 ± 0.05 based on its crude protein content. No unusual fatty acids were detected in the biomass.

鮸鱼肌肉和副产物营养组成分析及评价

对鮸鱼肌肉和副产物营养成分进行测定,鮸鱼肌肉和副产物水分含量分别为79.65%与69.15%,蛋白质含量分别为18.65%与19.36%,粗脂肪含量分别为0.24%与3.90%,灰分含量分别为1.15%与3.75%。鮸鱼肌肉和副产物的氨基酸总量(TAA)分别为18.58%与15.47%,必需氨基酸(EAA)质量分数分别为7.65%与5.52%,但只有鮸鱼肌肉的EAA/TAA(41.17%)与EAA/非必需氨基酸(69.99%)符合FAO/WHO优质蛋白质标准。氨基酸评分和化学评分的结果表明鮸鱼肌肉和副产物的第一限制性氨基酸均为蛋氨酸。鮸鱼肌肉必需氨基酸指数(EAAI)为89.07,副产物的EAAI为61.78。鮸鱼肌肉和副产物都含有丰富的丁酸、棕榈油酸、油酸、神经酸、二十二碳六烯酸、Mg、Ca、K和Fe。鮸鱼肌肉和副产物是高蛋白质、低脂肪、富含矿物质的食品源。     

Nutritional and anti-nutritional characteristics of mucuna (Mucuna utilis) bean seeds

Some nutritional and anti-nutritional characteristics of mucuna (Mucuna utilis (Wight) Burck) bean seeds were studied. The mature seeds contained 264 g crude protein, 63 g crude fibre, 41 g crude fat, 37 g ash and 595 g carbohydrates kg^?1 DM. The essential amino acid profile compared well with the FAO/WHO scoring pattern except for a deficiency of sulphur-containing amino acids. Mineral composition was similar to those reported for most tropical grain legumes. Raw mucuna seed samples contained moderately high levels of anti-tryptic activity (2170 trypsin units inhibited g^?1 DM), but this was completely destroyed by cooking. The other anti-nutritional factors (phytate, cyanide and tannins) are probably of little nutritional significance provided that the beans are properly processed. The in-vitro protein digestibility of raw and cooked beans were 71·5 and 80·3 %, respectively. In view of the high L-DOPA contents reported in some mucuna cultivars, overconsumption of mucuna beans should be viewed with some caution until suitable processing methods are developed.

Proximate Composition,Calorie Content and Heavy Metals (As,Cd, Pb) of Selected Sri Lankan Traditional Rice (Oryza Sativa L.) Varieties

There are over 2000 Sri Lankan traditional rice varieties (STRV) known to have existed in Sri Lanka. But only about 30 varieties have been subjected to scientific research and proven to have high nutritional and medicinal properties. Therefore, uncovering the nutritional values of the rest of the STRV has become very important. Standard methods of AOAC nutritional guidelines were used to obtain the proximate composition of six STRV; Kalu heenati (KH), Pokkali (PK), Gurusinghe wee (GW), Kahawanu (KW), Sudu murunga (SM) and Unakola samba (US). Heavy metals (As, Cd and Pb) of these STRV were determined by using an ICP-AES.The moisture content of selected STRV ranged from 11.2±0.2% -11.9± 0.2%. The results showed that crude protein content of the selected STRV was in the range of 9.7±0.3% - 11.0±0.4% KH had the highest crude protein content while SM had the least. In relation to crude fiber content, SM had the highest percentage (1.14±0.04%), while the lowest (0.92±0.03%) was recorded for KH. Crude fat content of all the STRV ranged from 2.3±0.0% - 2.9±0.1%. US had the highest crude fat content while PK and GW similarly had the least. PK had the highest ash content of 1.9±0.1% and the least ash content of 1.2±0.0% was shown by SM. Carbohydrate content of the selected STRV ranged from 72.0±0.1% - 76.3±0.1%. Calorie contents of the selected STRV were in the range of 352.3-372.8 Kcal/100 g and the highest value was reported for KH. The study reveals that the levels of As, Cd and Pb were below the limit of quantification (LOQ: Pb-0.04 ppm, As-0.02 ppm and Cd-0.01 ppm). Therefore, consumption of STRV may not cause metal toxicity due to Pb, Cd or As. This reveals that STRV show high nutritional values than those values reported for the improved rice.     

Nutritional and physicochemical evaluations of tahina (sesame butter) prepared from heat‐treated sesame seeds

Dehulled sesame seeds were roasted using different heat treatments. The effects of roasting treatments on the nutritive value, physicochemical properties and sensory properties of produced tahina were studied. Resultant tahina contained 586–594 g kg⁻¹ crude oil, 219–226 g kg⁻¹ crude protein and <30 g kg⁻¹ crude fibre and ash. Crude protein, crude fibre, ash and N‐free extract in tahina samples were not affected by roasting treatments. However, crude oil was decreased by steam roasting and hot plate roasting. Hot plate roasting was more effective in reducing raffinose content than other roasting treatments, whereas vacuum roasting was less effective in reducing raffinose content than other roasting treatments. Tahinas were good sources of essential amino acids, especially sulphur‐containing amino acids, aromatic amino acids and tryptophan. Hot air roasted tahina followed by vacuum roasted tahina had higher total essential amino acid contents than steam roasted and hot plate roasted tahinas. Lysine was the first limiting amino acid in tahinas. Tahinas had a relatively high in vitro protein digestibility (over 83%). Tahina is a good source of niacin. Hot air roasted tahina had the highest content of B group vitamins compared with other tahina samples. Resultant tahinas had relatively high amounts of Na, Mg, K, Cu, Zn and Fe and a low amount of Ca. Roasting treatments did not affect the mineral contents. All roasted samples had a typical protein spectrum with a maximum absorption at 280 nm and minimum at 260 nm. However, the spectrum of hot air roasted tahina proteins was sharper than the spectra of other tahina proteins. Size exclusion HPLC fractionated tahina proteins into two fractions for hot roasted and vacuum roasted tahinas and three fractions for steam roasted and hot plate roasted tahinas. The gel filtration pattern of tahina proteins contained four peaks with identical elution volumes but different proportions. Hot air roasted and vacuum roasted tahinas had higher panel scores than steam roasted and hot plate roasted tahinas for all tested sensory properties. © 2000 Society of Chemical Industry     

VARIATION AND RELATIONSHIPS AMONG SOME NUTRITIONAL TRAITS IN SICILIAN GENOTYPES OF CHICKPEA (CICER ARIETINUM L.)

The chemical composition of several chickpeas originating from Sicily, compared with the International Center for Agricultural Research in the Dry Areas genotype “ILC 484” and the Italian cultivar “Calia,” was determined. A large variability was ascertained for crude fiber (coefficient of variation [CV] = 29.3%), calcium (CV = 39.3%) and tannins (CV = 120.0%). The genotype statistically affected all nutrient characteristics assessed, whose mean values were: (1) 100‐seed weight 34.0 ± 3.3 g; (2) crude fiber 2.88 ± 0.8 g/100 g; (3) fat 6.0 ± 0.9 g/100 g; (4) total carbohydrates 62.0 ± 1.4 g/100 g; (5) ash 2.64 ± 0.2 g/100 g; (6) iron 4.50 ± 0.3 mg/100 g; (7) calcium 109.6 ± 43.1 mg/100 g; (8) magnesium 189.4 ± 18.5 mg/100 g; (9) potassium 1318.7 ± 95.6 mg/100 g; and (10) tannins 0.90 ± 1.1 g/100 g. An average energy value of 379.8 ± 6.2 kcal/100 g was computed. The wide variability ascertained for some chemical attributes such as crude fiber, tannins and Ca content, and interesting correlations observed among characteristics, such as the negative correlation between Fe and tannins or fiber, or the positive correlation between ash and Fe, suggest the possibility of identifying genotypes to be used in breeding programs for the improvement of chickpea quality in Sicily.     

Composition of Saccharomyces fragilis biomass grown on lactose permeate

Saccharomyces fragilis (NRRL y 1109) was grown on a medium composed of Cheddar cheese whey ultrafiltration permeate, supplemented with inorganic nitrogen. The biomass had a crude protein content of 49.5% and an ash content of 7.6%. The “true protein” content, based on a N fractionation procedure was 37.2% and the total nucleic acid content was 5.7%. Qualitatively, the amino acid composition of S. fragilis was similar to that reported for other whey-yeasts. The quantity of individual essential amino acids was greater in the permeate grown S. fragilis. The sulphur containing amino acids, methionine and cyst(e)ine were present at a combined level of 3.2 g/16g N, compared with 2.2g/16 g N in a commercial whey-yeast product. The chemical score (CS) and essential amino acid index (EAAI) were 58.2 and 76.0 respectively. Rats fed on a diet containing S. fragilis biomass as the sole source of dietary protein showed a net weight increase. NPU_carcass for S. fragilis protein was 67.0±3.9 compared with a value of 75.3±3.0 for a casein control. Supplementation of S. fragilis biomass with DL-methionine(2 g/16 g N) raised the NPU_carcass value to 84.4 ± 2.8.     

Biochemical and nutritional evaluation of Egreria radiata (clam), a delicacy of some riverine peasant populations in Nigeria

Proximate, mineral and amino acid analyses of the edible portion of clam (Egreria radiata), a delicacy of some riverine peasant populations in Nigeria, were carried out. The protein quality of the delicacy was also evaluated in a rat bioassay. Crude protein content was 61·0 ± 0·81%; crude fat, 19·0 ± 0·33%; carbohydrate, 1·40 ± 0·02%; crude fibre, 0·40 ± 0·00%, and ash, 17·4 ± 0·51%. Among the essential amino acids assayed, valine, with a chemical score of 37·5%, appeared to be the most limiting, as others had scores of over 55%, when compared with the essential amino acid pattern of whole hen's egg. Elemental analyses showed that, of the trace elements, clam was rich in iron, zinc and manganese, and also contained reasonable amounts of other elements. The PER, NPU, TD and BV were 2·55 ± 0·35, 65·7 ± 1·80, 85·3 ± 3·90 and 77·1 ± 3·35, respectively. These values compared reasonably well with those for whole hen's egg. The high nutritional qualities of the edible portion of clam justify its consumption and also recommend its wider use as a cheap good source of animal protein.     

Breadfruit (Artocarpus communis) meal: Nutrient composition and feeding value for broilers

Breadfruit (Artocarpus communis) meal was found to contain (g kg dry matter) 59 crude protein, 14 crude fat, 59 crude fibre, 34 ash and 834 available carbohydrates. The amino acid composition of breadfruit meal (BFM) compared closely with that of maize. The nitrogen-corrected apparent metabolisable energy value of BFM was determined to be 13.89 MJ kg^?1 dry matter. Two trials were conducted to evaluate the feeding value of BFM in broiler diets. In trial 1. BFM was included in broiler starter and finisher diets at 0, 125 and 250 g kg^?1 replacing maize. In trial 2, BFM was incorporated in broiler starter diets at 0, 200 and 400 g kg^?1 replacing maize. The results indicate that BFM supported broiler performance as efficiently as maize at all dietary levels tested.
