Abstract

Purpose

The purpose of the present study was to investigate the effect of camel milk protein hydrolysates (CMPHs) on physico-chemical, sensory, colour profile and textural quality attributes of chevon patties.

Design/methodology/approach

Camel milk proteins were hydrolyzed with three different proteolytic enzymes, viz., alcalase (CMPH-A), α-chymotrypsin (CMPH-C) and papain (CMPH-P), and dried to powder form before further utilization. Four treatments were prepared with incorporation of CMPH, viz., CMPH 0 per cent (C), CMPH-A 0.09 per cent (T1), CMPH-C 0.06 per cent (T2) and CMPH-P 0.09 per cent (T3), in the product formulation. The developed goat meat patties were evaluated for physico-chemical (pH; emulsion stability, ES; cooking yield, CY; water activity, aw), instrumental colour and texture profile and sensory attributes.

Findings

The pH, moisture, fat and ES values of goat meat emulsions were comparable amongst treatments as well as with the control; however, treated emulsions had higher ES and moisture content. The pH and moisture per cent of cooked chevon patties varied significantly, whereas other physico-chemical (CY, aw, per cent protein, per cent fat, per cent ash and per cent dietary fibre) as well as dimensional parameters (per cent gain in height and decrease in diameter) were comparable amongst treatments and the control. Hardness, springiness, stringiness, cohesiveness, gumminess and resilience of chevon patties decreased significantly (p < 0.05) with the incorporation of CMPH than that of the control; however, the values were comparable among all the treated products. Protein hydrolysate in chevon patties resulted in significant increase in redness (a*) values, whereas all other parameters (L*, b* and hue) decreased significantly as compared to that of the control. The colour and appearance, texture, juiciness overall acceptability scores were comparable in all the treated products and were significantly (p < 0.05) higher than the control. The flavour scores of C, T1 and T3 were comparable but significantly lower than that of T2. The overall acceptability scores of T1 and T2 were also comparable and significantly higher than C and T3; however, the highest score was recorded for T2.

Practical implications

Results concluded that chevon patties with acceptable sensory attributes and improved CY and textural attributes can be successfully developed with the incorporation of CMPH.

Originality/value

The protein hydrolysates of different food proteins could be explored in a same pattern to find out their implication in food matrices.

Abstract

Purpose

Camel as a livestock plays an important role in desert ecosystem and its milk has potential contribution in human nutrition in the hot and arid regions of the world. This milk contains all the essential nutrients as found in other milk. Fresh and fermented camel milk has been used in different regions in the world including India, Russia and Sudan for human consumption as well as for treatment of a series of diseases such as dropsy, jaundice, tuberculosis, asthma and leishmaniasis or kala-azar. The present paper aims to explore the possibility of camel milk as an alternative milk for human consumption.

Design/methodology/approach

Recently, camel milk and its components were also reported to have other potential therapeutic properties, such as anti-carcinogenic, anti-diabetic, anti-hypertensive and renoprotective potential; and for autism, and has been recommended to be consumed by children who are allergic to bovine milk.

Findings

It has also been reported to alleviate oxidative stress and lipid peroxidation in rats. Camel milk differs from bovine milk in composition. It contains low total solids and fat; however, proteins and lactose are in equal amount but of higher quality than cow milk. Because of the high percentage of β-casein, low percentage of α-casein, deficiency of β-lactoglobulin and similarity of the immunoglobulins, it become safer for persons who are allergic to bovine milk. It contains protective proteins in higher amount which contributes to its functionality. The fermentation and enzymatic hydrolysis of camel protein produce different types of bioactive peptides which exerts different activity in in vitro and in vivo conditions.

Originality/value

Because of its unique quality and functionality, this milk has potential application in management of different diseases and application in food industries.

Abstract

Purpose

The purpose of this paper was to evaluate the effect of grape powder on the proximate, physicochemical and sensory quality of chocolate- and caramel-coated chhana (traditional dairy product obtained by acid coagulation of hot milk) delights.

Design/methodology/approach

The study was designed to evaluate the effect of grape powder on the quality characteristics of chocolate- and caramel-coated chhana delights. The product was developed by incorporating different levels of grape powder (2, 4 and 6 per cent), and further, the product was analysed for proximate, physicochemical and sensory parameters.

Findings

In chocolate-coated chhana delights, moisture (p = 0.01), ash (p = 0.03) and water activity (p = 0.02) increased significantly at 6 per cent level of grape powder incorporation, whereas pH (p > 0.01) showed a significant decreasing trend at 4 and 6 per cent level of grape powder incorporation. Chocolate coating loss (p = 0.02) was found to be significantly higher at 6 per cent level of addition. Cooking yield (p > 0.01) of chocolate-coated chhana delights increased significantly at 4 and 6 per cent level of grape powder incorporation. In caramel-coated chhana delights, moisture (p > 0.01) and ash (p = 0.02) content increased significantly at 6 per cent level of grape powder addition, and pH (p > 0.01) value decreased significantly at 6 per cent level of grape powder addition, whereas results were found to be vice versa in case of water activity (p = 0.01) and titratable acidity (p = 0.03) at 6 per cent level of grape powder addition.

Originality/value

Designer confection could be developed for school going children by incorporating grape powder in the formulation of chocolate- and caramel-coated chhana delights.
