Abstract

Purpose

This paper aims to determine the effects of 11S globulin isolated from Chickpea (Cicer arietinum L.) on lipid metabolism in animals subjected to a hypercholesterolemic and hyperlipidemic diet and compared to the drug simvastatin.

Design/methodology/approach

Thirty-six male Wistar rats, kept in individual cages and under appropriate conditions, were separated into groups that were fed a normal diet (STD) containing casein as protein source and according to AIN-93G; a high-cholesterol diet (HC), normal diet plus 1 per cent cholesterol and 0.5 per cent cholic acid and 20 per cent coconut oil; HC diet plus the isolated 11S globulin (300 mg/kg/day); and HC diet plus the simvastatin (50 mg/kg/day), both dissolved in saline and administered by gavage for 28 days. After this time, the animals were killed.

Findings

The results indicated that the addition of 1 per cent cholesterol and 0.5 per cent cholic acid induced hypercholesterolemia in the animals without interfering with their weight gain. Analyses of total cholesterol (TC), HDL-cholesterol (HDL-C) and triglycerides (TG) in the plasma, and TC and TG in the liver were made. The results show that the protein isolated from chickpea, and given as a single daily dose, did not affect the levels of plasma TC and its fractions, although decreasing the TG levels. Unlike the simvastatin, the chickpea protein significantly reduced TC and TG in the liver relative to HC group.

Originality/value

A single daily dose of 11S globulin from chickpea contributed as only as additional 2.8 per cent of dietary protein intake. These findings demonstrate that 11S chickpea protein acts as a functional agent in the lipid metabolism in addition to its nutritional properties.

Abstract

Purpose

The purpose of this study is to compare the effect of olive or salmon oil on the hepatic storage and transport of fatty acids by very-low-density lipoproteins (VLDL).

Design/methodology/approach

In all, 24 male Wistar rats (80 ± 5 g) were fed a 0.5 per cent cholesterol-enriched diet with either 20 per cent casein (C) or chickpea (CP) proteins with 10 per cent olive (O) or salmon (S) oil for 28 days.

Findings

In VLDL-triacyglycerols fatty acids, oleic acid content was higher in CPS as compared to that in CS or CPO and lower in CS and CPO than that in CO; linoleic acid content was higher in all groups; arachidonic acid content was higher in CS and CPO as compared to that in CO. In the liver, TG fatty acids content was lower in CPO or CPS as compared to that in CO or CS; oleic and arachidonic acid contents were lower in CPS than that in CPO; linoleic acid content was lower in CS, CPS and CPO than that in CO, CPO and CO. In liver, phospholipid fatty acid, oleic and arachidonic acid contents were lower in CPS than that in CS; oleic, linoleic and arachidonic acid contents were lower in CPO compared to that in CO. In liver, cholesteryl esters fatty acids, oleic, linoleic and arachidonic acids contents were higher in CPS as compared to that in CS; oleic, linoleic and arachidonic acid contents were lower in CS as compared to that in CO; linoleic and arachidonic acid contents were lower in CPS than that in CPO.

Originality/value

A cholesterol-enriched diet containing casein or chickpea proteins combined with olive or salmon oil affects the hepatic storage and transport of polyunsaturated and monounsaturated fatty acids by VLDL.

Abstract

Purpose

Iron deficiency anaemia and zinc deficiency are major public health problems across the globe. Cereals and pulses are important vegetarian source of minerals like zinc (Zn) and iron (Fe), however, poor digestibility impairs proper availability of micro minerals in the body. Chickpea (Cicer arietinum L.) and cowpea (Vigna unguiculata L. Walp) were selected for study as they are important pulse crops consumed worldwide. Therefore, in order to remove antinutrients and enhance bioavailability of nutrients in chickpea and cowpea, extrusion cooking was selected as a technology and its impact was studied by an in vitro method. The paper aims to discuss this issue.

Design/methodology/approach

Four chickpea cultivars, two desi (K 850 and PUSA 362) and two kabuli (PUSA 1108 and PUSA 1053) and one cowpea (Gomati) cultivars were selected for the study. Pulses were processed in a laboratory using a single screw food extruder. Raw and extruded pulses were analysed for antinutrients content, micronutrients content (Fe, Zn) and their bioavailability.

Findings

Extrusion cooking significantly decreased phytate in all cultivars of chick pea and cowpea with highest reduction (72.92 per cent) in PUSA 362; similarly, tannin and trypsin inhibitor decreased by 87.5 and 71.54 per cent, respectively, in Gomati cultivar of cowpea. All cultivars showed significant increase in protein digestibility. Iron bioavailability in all samples enhanced significantly; however, only 50 per cent cultivars (K 850, PUSA 362 and PUSA 1108) showed improvement in Zn bioavailability.

Originality/value

The present research therefore brought the outcome as an enhanced in vitro protein digestibility and bioavailability of micro mineral and protein in certain pulses having minimized antinutrients. Therefore, it is concluded that extrusion cooking is an effective tool in enhancing protein and micro mineral bioavailability.

Abstract

Purpose

The major objective of this research work was to evaluate various physico-chemical characteristics, such as, chemical composition, antioxidant capacity, objective color and texture profile analysis (TPA) of the wheat flour/chickpea flour (CF) blends, so that nutritious baked products could be consumed by the type-2 diabetic persons.

Design/methodology/approach

Wholegrain wheat flour (WGF) and white wheat flour (WWF) were substituted with CF at 0 to 40% levels. These wheat flour/CF blends were analyzed for proximate composition, the prepared dough and baked breads were tested for objective color, antioxidant capacity as trolox equivalent antioxidant capacity (TEAC), malondialdehyde (MDA) and total phenolic content (TPC) and TPA.

Findings

WGF had the highest TEAC (117.42 mM/100g) value, followed by WWF (73.98 mM/100g) and CF (60.67 mM/100g). TEAC, MDA and TPC values varied significantly among all the three flour samples.

Research limitations/implications

Inclusion of whole chickpea (without dehulling) flour in such type of blends would be another interesting investigation during the future research studies.

Practical implications

These research findings have a great potential for the production of these baked products for human consumption on an industrial scale.

Social implications

Production of breads using wheat flour and CF blends would benefits the consumers.

Originality/value

Production of Arabic and pan breads using wheat flour and CF blends would, therefore, combine the benefits of both the needed proteins of plant origin and the health-promoting bioactive compounds, in a most sustainable way for the consumers.

Abstract

Purpose

The purpose of this study was to determine the effects of chickpea (Cicer arietinum) protein hydrolysates prepared at two degrees of hydrolysis (DH) on lipoprotein profile and on oxidant status in cholesterol-fed rats.

Design/methodology/approach

Eighteen male Wistar rats (220 ± 10 g) were divided into three groups and fed for 30 days a diet containing 20 per cent casein supplemented with 1 per cent cholesterol and 0.5 per cent cholic acid. During the experimentation, the first and the second groups received daily by gavage 250 mg of chickpea protein hydrolysates/rat at DH = 8 per cent (CPH8) and DH = 17 per cent (CPH17), respectively. The third group, named control group (CG), received water under the same conditions.

Findings

Serum total cholesterol concentrations were reduced in CPH8 (p < 0.0073) and CPH17 (p < 0.0004) groups versus CG. This reduction corresponded to a lower very-low-density lipoprotein (VLDL)-cholesterol (p < 0,0019). CPH17 reduced low-density lipoprotein- and high-density lipoprotein (HDL)-cholesterol (p < 0.0001) but increased apolipoprotein A4 (p < 0.002) concentrations and lecithin-cholesterol acyltransferase activity (p < 0.0001). APOA1 remained unchanged in the treated groups. Liver total and esterified cholesterol contents were twofold lower in both treated groups versus CG. CPH8 increased triacylglycerols and phospholipids (p < 0.0001) contents, while CPH17 decreased those of unesterified cholesterol (p < 0.0016). Compared with CG, CPH8 and CPH17 reduced serum (p < 0.0001) and lipoprotein hydroperoxides by stimulating paraoxonase activity (p < 0.0001). However, only CPH17 treatment reduced serum, VLDL- and HDL-malondialdehyde contents and improved glutathione peroxidase activity (p < 0.061).

Originality/value

Thus, chickpea protein hydrolysates and especially hydrolysed at DH = 17 per cent may have a great potential for use as a nutraceutical to reduce hypercholesterolaemia and, by consequence, oxidative stress. Therefore, the degree of enzymatic hydrolysis has a significant influence on the production of potent bioactive peptides.

Abstract

Purpose

The purpose of this paper is to determine the effects of different dietary protein and lipid origins on serum HDL2 and HDL3 compositions and lecithin: cholesterol acyltransferase (LCAT) activity in growing rats fed a 0.5 per cent cholesterol‐enriched diet with either 20 per cent casein (C), chick pea (CP) or lentil (L) proteins combined to 10 per cent olive (O) or salmon (S) oil for 28 days.

Design/methodology/approach

HDL2 and HDL3 separation according to Sjöblom and Eklund and LCAT activity according to Glomset and Wright.

Findings

Serum total cholesterol was 1.3‐fold lower in CPS than in CPO group. HDL3 amounts were 2‐ and 1.5‐fold higher in CPO and LO groups, respectively, compared to CO group. HDL3‐unesterified cholesterol values were, respectively, 2‐ and 5‐fold lower in CPO and LO groups than in CO group, and were threefold decreased in CPS and LS groups vs CS group. HDL3‐phospholipids in LO group represented 12 and 51 per cent of the CO and CPO group values, respectively. HDL2‐triacylglycerol amounts were decreased in LO group vs CO group (−67 per cent) and in CPS and LS groups (−62 per cent) compared to CS group. HDL3‐apolipoprotein A‐I values were lower in LO group vs CO and CPO groups, and in CPS group vs CS group. However, LCAT activity was similar in all the studied groups.

Originality/value

The paper shows that when diets containing casein, chick pea or lentil proteins combined with olive or salmon oil are supplemented with cholesterol, HDL2 and HDL3 compositions are impaired despite unchanged LCAT activity. Moreover, if oils modify HDL compositions, dietary proteins play a critical role in these modifications.

Abstract

Purpose

The purpose of this paper is a study designed to utilize Vigna mungo L. (black gram) flour to improve the protein quality of wheat through supplementation. Wheat is utilized as a cereal crop all over the world, but its protein quality is inferior owing to the deficiency of amino acids like lysine.

Design/methodology/approach

Black gram seeds were roasted and germinated and then incorporated at 10, 15 and 20 per cent level in wheat flour. The composite flour was evaluated for its chemical composition, physiochemical properties and rheological characteristics, and cookies were developed from the composite flour.

Findings

Chemical composition of composite flour revealed significant results (p < 0.05). The level of crude protein increased from 9.69 to 11.79 per cent, while ash and crude fat content enhanced from 0.33 to 1.80 per cent and 1.13 to 2.40 per cent, respectively. There was a significant effect (p < 0.05) on the sedimentation value by the addition of black gram in wheat flour. Water absorption of composite flour was higher than control (52.21 per cent), as maximum value was observed in flour having 15 per cent germinated black gram flour (69.45 per cent). Dough development time also increased from 2.90 min to 4.80 min. The pasting properties revealed significant results for all the parameters. Cookies were developed from composite flour, and sensory evaluation has shown that addition of pulse flour at 15 per cent yields cookies with better hedonic response.

Originality/value

The black gram is a locally grown legume crop, but there is a lack of systematic approach for its chemical composition and product development. Scientists are in urge to explore such economical and assessable food ingredients to cope with the nutritional deficiencies prevailing in the developing societies. In this regard, black gram has been recognized as a rich source of nutrients, so it can be exploited to improve wheat protein quality.

This paper aims to investigate the in vivo hypocholesterolemic property of fenugreek proteins (FP), Purafect-fenugreek protein hydrolysate (PFPH) and Esperase-fenugreek protein

Abstract

Purpose

This paper aims to investigate the in vivo hypocholesterolemic property of fenugreek proteins (FP), Purafect-fenugreek protein hydrolysate (PFPH) and Esperase-fenugreek protein hydrolysate (EFPH) on high cholesterol (HC)-fed rats.

Design/methodology/approach

Rats were randomized into five groups: four were fed for four weeks a hypercholesterolemic diet and the tested products were given by gavage. The fifth group was taken as control (C) receiving the same diet without cholesterol.

Findings

Results showed that the elevated aspartate aminotransferase activity in HC group plasma was significantly corrected by FP and EFPH administration (−33 per cent; p = 0.0003). HC liver lipids and total cholesterol (TC) contents were not markedly affected by FP and EFPH. However, liver triglycerides (TG) contents trended to decrease in FP rats vs HC (p = 0.07), while, the TG decrease was significant in groups fed the proteins hydrolysates (p = 0.02). On the other hand, serum TC and TG decreased by 53 per cent (p = 0.0003) and 20 per cent (p = 0.04), respectively, in FP treated rats compared to HC group. This decrease was associated with a high fecal cholesterol excretion (2.5-fold higher in FP vs HC; p = 0.0001). Likewise, EFPH-treated rats exhibited lower TC compared to HC rats (p = 0.004). The very low density lipoprotins was the main affected fraction in these two groups, while there were no significant difference in apolipoproteins (Apo) B, A-I and A-IV contents between the different groups, except in FP group, where Apo A-I and A-IV decreased by 26 and 17 per cent, respectively, compared to C rats (p = 0.02). The high density lipoproteins (HDL) of rats treated with proteins hydrolysates showed a better antioxidant property compared to those of HC rats, which was accompanied with an increase in paraoxonase activity when compared to HC group.

Originality/value

Unlike PFPH which had almost no effect, FPs and EFPH could constitute a nutraceutical ingredient in cardiovascular disease management.

Abstract

Purpose

This study aims to investigate the influence of soy protein isolate hydrolysates (SPIH) obtained using 4 h hydrolysis under 200 MPa on proximate composition, cooking loss, textural properties, color, water distribution, microstructure, thiobarbituric acid reactive substance (TBARS) value and carbonyl and sulfhydryl contents of emulsion sausages.

Design/methodology/approach

Sausages with SPIHs at four concentrations (0, 1.0, 2.0 and 3.0%) were prepared, and the sausage with 0.01% butylated hydroxyanisole (BHA) was used as a positive control. Some sausages were selected for the analyses of quality characteristics and microcosmic properties. Other sausages were stored under 4 °C for 0, 7, 14, 21 and 28 days to investigate the oxidative stability.

Findings

The addition of SPIHs at various levels (0–3.0%) or 0.01% BHA did not affect the proximate composition (protein, fat and ash) of emulsion sausages. The addition of 2.0% SPIH decreased cooking loss and increased moisture content, hardness, springiness, chewiness, resilience and L* value, compared to the sausages without SPIH and with 0.01% BHA (p < 0.05). Furthermore, low-field nuclear magnetic resonance results suggested that sausages with 2.0% SPIH had the shortest T2 relaxation time. In addition, 2.0% SPIH and 0.01% BHA could inhibit the oxidation of emulsion sausages when compared with the sample without SPIH (p < 0.05). Moreover, there were no differences between sausages with 2.0% SPIH and 0.01% BHA (p > 0.05).

Originality/value

These findings confirmed that the 2.0% SPIH obtained under 200 MPa can be used as a natural additive to improve quality properties and antioxidant potential of emulsion sausages during storage.

This paper aims to standardize level of spent hen meat powder incorporation in whole wheat bread without affecting the bread structure.

Abstract

Purpose

This paper aims to standardize level of spent hen meat powder incorporation in whole wheat bread without affecting the bread structure.

Design/methodology/approach

Spent hen meat powder at 20, 30 and 40 per cent level was used for substitution of whole wheat flour.

Findings

The results revealed that increasing the level of meat powder brought about significant (p < 0.05) effect on physicochemical parameters, proximate composition, textural profile and instrumental colour values (except hue). The pH, baking loss, carbohydrate content, energy and moisture protein ratio decreased significantly (p < 0.05) with meat powder incorporation. Whereas, moisture, protein, fat, ash and moisture retention values increased significantly (p < 0.05) with whole wheat substitution. Meat powder addition increased all the textural profile parameters significantly (p < 0.05). Redness, yellowness and chroma values also increased significantly (p < 0.05) with replacement of whole wheat flour. Sensory evaluation showed variable effect of higher meat powder incorporation. The colour of crust, crumb and flavour evinced significant (p < 0.05) increase with level of incorporation, while porosity and texture decreased significantly (p < 0.05). The overall acceptability of 30 per cent replacement was the highest.

Research limitations/implications

Storage stability and preservation aspect can be further explored for better shelf life at ambient temperature.

Practical implications

The development of such a product would definitely be profitable to the poultry industry by opening new avenues for under-used spent hen meat and meat processors.

Social implications

Addition of meat not only channels better utilization of spent hen meat but also enhances economical return to farmers and the meat industry; it also helps in accomplishing protein requirement of consumers.

Originality/value

The addition of spent hen meat enhanced the physico-chemical and sensory attributes of the treated groups than control. It is a novel nutritionally rich alternative for regular breads.
