Water stress during the reproductive phase, especially during seed development, is considered detrimental for chickpea yield. In the present study, the relative sensitivity of Desi and Kabuli chickpea types to water stress during seed filling was assessed in terms of effects on quantitative and qualitative aspects of seed yield. Leaves of both types experienced stress injury (evaluated as electrolyte leakage) to the same extent and possessed almost similar values of water potential at the end of 14 days of water stress. The stressed plants of Kabuli type lost more chlorophyll and had less photosynthesis than Desi type. At maturity, Desi type showed more diminution of vegetative dry matter due to stress over control than Kabuli type. On the other hand, Kabuli type showed a proportionally greater reduction in seed weight per plant, average seed weight, average seed size, number of pods (single‐ and double‐seeded) and harvest index. The stressed seeds of Kabuli type showed 48 and 46% reduction over control in starch and protein content compared with 25 and 40%, respectively in Desi type. The accumulation of soluble sugars was relatively greater due to stress in Kabuli (47%) than Desi type (23%). Fat and fiber content declined by 39 and 35% over control in Desi seeds because of stress whereas Kabuli type showed 46 and 67% decreases, respectively. Protein fractions, namely albumins, globulins, glutelins and prolamins, decreased in stressed seeds of Kabuli by 32, 40, 16 and 15% over control relative to 40, 48, 30 and 28%, respectively, in Kabuli type. The activities of sucrose synthase, invertase and soluble starch synthase were inhibited to a higher extent in Kabuli seeds than Desi seeds under stress. Kabuli seeds showed significantly more reduction in the accumulation of amino acids such as phenylalanine + tyrosine, tryptophan, valine, alanine and histidine and minerals (Ca, P, Fe) due to stress compared with Desi type.

The suitability of chickpea grown in Western-Canada was studied in a low-fat (fat <5%) emulsion-type meat product as a model. Six high-yielding chickpea varieties were screened and one Kabuli and Desi variety were selected for testing in a meat system. The physiochemical, textural and sensory properties of low-fat pork bologna extended with chickpea flour (or pea and wheat flour as comparisons) at 2.5% and 5.0% were investigated. Inclusion of chickpea flour improved the product’s instrumental and sensory texture properties. Bologna with added Kabuli and Desi chickpea flour performed similar to the control (no added binder) for most flavour properties. However, panelists noted more foreign-flavours with addition of wheat and pea flour at 5.0%. This study shows that chickpea flour is a potential source of high protein flour for use as an extender in emulsified meat products due to its superior technological functionality and minimal effects on flavour.  相似文献

不同品种鹰嘴豆淀粉糊与凝胶特性研究   总被引:7,自引:0,他引:7  
以不同品种的鹰嘴豆Kabuli和Desi为原料,采用快速黏度仪、质构仪和流变仪研究淀粉糊与凝胶特性的差异。研究表明:Kabuli淀粉在糊化过程中的峰值、谷值、最终黏度等特征值均高于Desi淀粉,而降落值、回值及成糊温度却低于Desi淀粉。Kabuli淀粉的品质优于Desi淀粉,但这2种鹰嘴豆淀粉糊的糊丝均属于短糊系列。在不同热过程中Desi淀粉形成凝胶速度快,强度大;Kabuli淀粉的凝胶强度随温度的变化是可逆的。Kabuli淀粉凝胶破裂强度、弹性模量均小于Desi淀粉凝胶。  相似文献

High yielding cultivars of chickpea (Desi and Kabuli) (Cicer arietinum) and lentil (Lens esculenta) were analysed for their total mineral content, per cent availability (in vitro) of minerals and level of antinutrients. Gora Hisari (Kabuli chickpea), Haryana channa (Desi chickpea) and La-12 (lentil) were found superior. These cultivars contain highest per cent availability (in vitro) of calcium and iron and lowest values of phytic acid and polyphenols compared to other cultivan of chickpea and lentil.  相似文献

A study was made of both Desi (16 cultivars) and Kabuli (21 cultivars) chickpea biotypes grown under the same environmental conditions in order to evaluate the influence of the biotype factor as source of variance of the proximate composition and antinutritive substances content. Differences were found between the two biotypes for fat, total dietary fibre (TDF), insoluble dietary fibre (IDF), phytic acid and tannin content. Desi biotypes revealed lower fat and phytic acid contents, whereas Kabuli biotypes showed lower TDF, IDF and tannin content. Differences in coat thickness, as reported in the literature, are confirmed as a source of differences between the two biotypes in the fat, TDF, IDF, phytic acid and tannin content. © 1998 Society of Chemical Industry.  相似文献

The feeding value of feed grade chickpeas (Kabuli and Desi type) for ruminants and pigs was determined in two studies. Two ruminally fistulated cows were used in the first study to determine the effects of moist heat treatment (127 °C for 10 min) on the ruminal protein degradability of feed grade chickpeas. Heat treatment reduced (P < 0.05) soluble crude protein and increased (P < 0.05) the amount of crude protein associated with neutral detergent fibre for both types of chickpeas. Ruminal degradability of crude protein for Kabuli and Desi chickpeas was reduced by 39 and 33% (P < 0.05) respectively as a result of heating. In the second study, 64 crossbred pigs were each assigned to one of four dietary treatments in a factorial (4 treatments × 2 sexes) design experiment. The experimental barley/wheat‐based diets were supplemented with either soybean meal (control), Kabuli chickpeas (300 g kg−1), Desi chickpeas (300 g kg−1) or field peas (300 g kg−1). Dry matter and gross energy digestibility coefficients, determined using the indicator method, were lower (P < 0.05) for the Desi‐ than for the Kabuli‐supplemented diet. However, no differences were observed in dry matter or gross energy digestibility between the Kabuli chickpea‐supplemented diet and the control or the field pea‐supplemented diet. Diets supplemented with chickpeas or field peas had a lower (P < 0.05) crude protein digestibility than the control diet. Pigs fed either of the chickpea‐supplemented diets during the growing phase gained less (P < 0.05) than pigs fed the control diet. However, during the finishing phase and over the entire experiment, dietary treatment had no effect on pig performance. There were no significant differences in carcass traits between pigs fed any of the four diets. It was concluded that moist heat treatment is an effective method to increase the rumen escape protein value of chickpeas and that the inclusion of feed grade Kabuli or Desi chickpeas in finishing diets up 300 g kg−1 had no detrimental effects on pig performance. © 2000 Society of Chemical Industry  相似文献

An experiment was conducted to compare the nutritional composition of 16 varieties of chickpeas (Kabuli and Desi) and to determine their nutrient digestibility for swine using the mobile nylon bag technique. The average crude protein content of the Kabuli chickpeas (226 g kg?1) was lower than that of the Desi chickpeas (235 g kg?1). Desi chickpeas were higher in acid detergent fibre (145 versus 50 g kg?1) and neutral detergent fibre (264 versus 181 g kg?1) than Kabuli chickpeas. Digestibility coefficients for dry matter (83.1 versus 72.5%), gross energy (83.5 versus 74.8%) and crude protein (83.7 versus 79.4%) were higher for Kabuli chickpeas than for Desi chickpeas. Based on chemical analysis and nutrient digestibility, Kabuli chickpeas would appear to have greater potential as a protein and energy source for use in swine rations than Desi chickpeas. © 2002 Society of Chemical Industry  相似文献

BACKGROUND: A field experiment was conducted during the two winter seasons of 2007/2008 and 2008/2009 to evaluate the yield and its components, milling, technological and rheological characteristics as well as the correlation between these characteristics of eight bread wheat ( Triticum aestivum L.) cultivars (Gemmeiza 7, Gemmeiza 9, Gemmeiza 10, Sakha 92, Sakha 93, Sakha 94, Giza 164 and Giza 168). These cultivars were chosen because they were new. RESULTS: Gemmeiza 10 was shown to have the highest number of tillers and spikes per square meter, number of grains per spike and grain yield per hectare, followed by Gemmeiza 9, Giza 168, Sakha 94, Sakha 93, Sakha 92 and Giza 164. However, Gemmeiza 7 had highest biological yield per hectare, fine and coarse bran, protein, and wet and dry gluten percentages as well as farinograph properties. Giza 168 canopies were the tallest and also the straw yield was the highest. Also, Sakha 93 surpassed the other tested varieties in harvest index, flour and carbohydrate percentages. There are highly significant and positive correlations between each of grain yield per hectare and most of its components. The correlation between each of grain yield per hectare, flour and total carbohydrate percentages and dough weakness was found to be significant and positive. However, there was a negative correlation between each of grain yield per hectare, protein, gluten and bran percentages and farinograph properties. CONCLUSION: Gemmeiza 10 cv. surpassed in yield factors and most of its components. However, Gemmeiza 7 cv. gave the highest values of grain and flour quality. On the other hand, the highest total carbohydrate and flour percentages were obtained from Sakha 93 cv. Copyright © 2010 Society of Chemical Industry  相似文献

ABSTRACT:  Albumin and globulin fractions of 1 Desi and 2 Kabuli varieties of chickpeas ( Cicer arietinum ) were extracted with water and salt solutions (K2SO4 and NaCl). The extractable yields and particularly the albumin-globulin ratio varied greatly with the extraction medium and chickpea variety. Depending on the procedure employed, albumin could be extracted as a major fraction of chickpea proteins. Higher levels of essential amino acids and sulfur containing amino acids were found in albumins than in globulins of all chickpeas investigated. The common structural characteristics of both Kabuli and Desi chickpea albumins and globulins were clearly identified by densitometric profiles of their sodium dodecyl sulfate polyacrylamide gel patterns. Albumins contained subunits with higher molecular weights than those of globulins. The in vitro digestibility of the chickpea proteins by papain, pepsin, chymotrypsin, and trypsin indicated that globulins were more susceptible to proteolytic hydrolysis.  相似文献

Proteins play an important role in imparting functional attributes like texture and shape, which determine the sensory quality of the foods. Boondi, a deep fried product from chickpea (Cicer arietinum L.) flour dispersion, is a popular snack food in India. Chickpea dhal (splits) or flour was subjected to various processing conditions like steaming and toasting, to determine their effect on the chickpea flour protein characteristics and on the product quality. Dhal and flour subjected to different heat treatments showed differences in their odor profiles. The SDS-PAGE of sodium phosphate buffer extracts of steamed dhal or flour showed that the high molecular weight (HMW) proteins of 66 to 100 kDa that were present in the untreated dhal were found to be absent in steamed dhal extracts. However, SDS buffer extracts on SDS-PAGE of these steamed samples did not show any difference between untreated and thermally treated dhal samples. Phosphate buffer extracts of the thermally treated flours were subjected to gel filtration chromatography and the results indicated that the HMW protein fraction content decreased significantly in the treated dhal or flour samples compared to control. Boondi prepared from the thermally treated dhal samples resulted in the loss of spherical shape of boondi. Thus, the results indicate that thermal treatment of chickpea dhal and flour influence changes in protein characteristics, the sensory profile and quality of boondi.  相似文献

Some high yielding cultivars of chickpea (Kabuli and desi) (Cicer arietinum) and lentil (Lens esculenta) were used for chemical analysis and physico-chemical properties namely protein, fat, sugars, starch, in vitro digestibility of starch and protein; seed weight, seed volume, seed density, hydration capacity, swelling capacity, water absorption capacity and cooking time. Among chickpea, Gora Hisari (Kabuli) and Haryana Chana (desi) cultivars, and among lentil LH 82-6 cultivar manifested higher contents of protein, fat, sugars, starch and in vitro digestibility of starch and protein. Values of seed volume, seed density, hydration capacity, swelling capacity and water absorption capacity were also found higher for these cultivars which might have contributed towards less cooking time.  相似文献

BACKGROUND: Commercial experience suggests that desi chickpea cultivars vary in their milling quality. However, the relative effects of cultivar, growing environment and their interaction are unknown. This study examined the Australian pulse quality method for its effectiveness in comparing the milling quality of breeding lines. The main aims were (1) to determine if there were significant genotypic differences, (2) to quantify the effects of trial, testa content and seed size and (3) to determine if any of the milling quality or seed parameters were correlated. This information would then be used to improve the reliability and efficiency of testing breeding lines. RESULTS: Large genotypic differences were observed for the milling parameters dehulling efficiency (DE) and splitting yield (SY). The range was greater for SY (16.6%) than for DE (5.8%). Genotype × Trial interactions were significant for DE and SY, while genotype rankings were generally consistent between trials. Seed size and testa content were not significantly associated with either DE or SY. Environmental stresses that affected yield did not appear to influence milling results. CONCLUSION: The methodology used in this study was able to measure genotypic differences in milling quality. The results suggest that an efficient protocol for testing milling quality of chickpea genotypes would include analysis of at least two sites early in the breeding programme to discard very‐low‐SY genotypes, and further testing in subsequent years including at least one other site to identify high‐SY genotypes if desired.

The levels of trypsin inhibitor activity were higher in both kabuli and desi seeds of chickpea than their chymotrypsin inhibitor activity. Mean values for the trypsin and chymotrypsin inhibitor units in dhal and seed samples of desi were higher as compared with kabuli cultivars. The presence of seed coat reduced the protein extraction. Mean values of polyphenolic compounds in seed samples of desi were more than twice that of kabuli and these differences disappeared in dhal samples indicating the distribution of these compounds mainly in the seed coat. The in vitro protein digestibility studies showed larger differences between desi seed and dhal samples when compared with kabuli seed and dhal samples. Polyphenolic compounds exhibited a highly significant and negative corretation (r = 0.872**) with in vitro digestibility of protein and a significant positive correlation with trypsin (r = 0.612*) and chymotrypsin (r = 0.507*) inhibitor activities.  相似文献

BACKGROUND: Chickpea (Cicer arietinum L.) seeds are a good source of protein that has potential applications in new product formulation and fortification. The main objectives of this study were to analyse the physicochemical, thermal and functional properties of chickpea protein isolates (CPIs) and compare them with those of soy (SPI) and pea (PPI) protein isolates. RESULTS: Extracted CPIs had mean protein contents of 728–853 g kg?1 (dry weight basis). Analysis of their deconvoluted Fourier transform infrared spectra gave secondary structure estimates of 25.6–32.7% α‐helices, 32.5–40.4% β‐sheets, 13.8–18.9% turns and 16.3–19.2% disordered structures. CPIs from CDC Xena, among Kabuli varieties, and Myles, among Desi varieties, as well as SPI had the highest water‐holding and oil absorption capacities. The emulsifying properties of Kabuli CPIs were superior to those of PPI and Desi CPIs and as good as those of SPI. The heat‐induced gelation properties of CPIs showed a minimum protein concentration required to form a gel structure ranging from 100 to 140 g L?1. Denaturation temperatures and enthalpies of CPIs ranged from 89.0 to 92.0 °C and from 2.4 to 4.0 J g?1 respectively. CONCLUSION: The results suggest that most physicochemical, thermal and functional properties of CPIs compare favourably with those of SPI and are better than those of PPI. Hence CPI may be suitable as a high‐quality substitute for SPI in food applications. Copyright © 2011 Society of Chemical Industry  相似文献

The influence of genetic biotype on the mineral composition of chickpea was studied. Experimental design included 37 cultivars of both Desi and Kabuli biotypes cultivated under the same climatic and agronomic conditions in order to exclude the variability of the results due to environment and genotype × environment interaction effects. The biotype, as source of variance in mineral composition, was a significant factor in explaining differences between Ca, Mg and K contents. Cu, Fe, Mn, Na and Zn contents did not show differences between biotypes. According to data previously published, differences may be explained by differences in the coat thickness and composition between biotypes. Two homogeneous subgroups of chickpea cultivars were identified, one having relatively high calcium contents and the other having relatively high iron contents.  相似文献

Field peas from two cultivars were dehulled and groats were processed by two protocols: (1) groats directly ground with water into a slurry and fractionated into fibre, protein and starch concentrates (groat wet fractionation, GWF), and (2) groats dry milled into flour and then wet fractionated using steps identical to that of protocol-1 (flour wet fractionation, FWF). The yield (%, w/w) and composition (%, w/w) of starch, protein and fibre concentrates from both protocols were determined. The data indicated that the FWF had significantly higher starch yield when compared to GWF. Scanning electron micrographs clearly suggested that better tissue fragmentation caused by dry milling may be responsible for better starch yield in FWF. The purity of starch isolate from FWF was lower than that of GWF. Brabender viscoamylographs showed differences in pasting properties of starches between protocols. Furthermore, the effect of sonication on starch yield and purity was studied between two wet fractionations. A combination of FWF with the sonication at 75% amplitude for 10 min showed better starch yield.  相似文献

Moisture absorption in seven chickpea cultivars and three field pea cultivars was investigated at 5, 15, 25 and/or 42°C using the Peleg model (M (t) = Mo + t/[K1+ K2t]). The Peleg constant K1 varied with temperature. At a given temperature, the lower the K1, the more water was absorbed. The Peleg constant K2 was almost unaffected by temperature and could be used to predict the equilibrium water absorption. A constant K3 expressing the temperature effect on water absorption (K1= K3T + K4) was developed to distinguish two types of chickpea — Desi and Kabuli. All chickpeas had similar composition and initial moisture. The difference in water absorption rate was probably due to thickness and structure of the seed coat. The Peleg model could be used to predict water absorption in chickpea and field pea.  相似文献

Four indigenous Desi chickpea (Cicer arietinum L.) cultivars grown in the Punjab Province of Pakistan have been analyzed to determine and compare their nutritional and compositional properties and to assess their role in human nutrition. Variability was observed among investigated cultivars in terms of physical characteristics of seeds, such as seed size, seed volume, seed density, hydration capacity, hydration index, swelling capacity and swelling index. Mineral composition showed that sufficient amounts of Ca, P, K, Cu, Zn and Mg were present to meet the macronutrient and micronutrient demand in human diets. Despite variations, potassium and manganese were noted as being present in highest and lowest concentrations, respectively, in all cultivars. The distribution patterns of various amino acids in these cultivars suggested sulfur-containing amino acids as limiting amino acids. Fatty acid profile indicated unsaturated fatty acids as major fatty acids in all cultivars. The levels of some of the anti-nutritional factors were also determined. The analysis showed almost similar proportions of biochemical constituents among all cultivars. The data show that, in terms of both quality and quantity, the Desi chickpea cultivars can serve as a significant source of essential amino acids, essential fatty acids and trace minerals to meet the demand of populations living in Punjab Province of Pakistan.  相似文献

The physicochemical properties of high amylose rice flour prepared from wet milling and dry milling were examined and the rice vermicelli quality made from these flour samples was evaluated. The effect of flour particle size on rice vermicelli quality was also determined. The milling method affected chemical compositions and all physicochemical properties of the flour. A higher degree of starch damage occurred in drymilled flour. Rice vermicelli made from dry‐milled flour had higher cooking losses and softer texture than that made from wet‐milled flour and the commercial reference products. Flour particle size influenced both cooking and textural quality of rice vermicelli but did not influence the water absorption index. Flours with larger particle sizes gave vermicelli with higher cooking loss and less desirable texture than flours with smaller particle sizes. Flour with particle sizes less than 200 mesh produced acceptable vermicelli in terms of cooking and textural quality.  相似文献
