The purpose of this study is to investigate the scope of the addition of seaweed powders for the development of low-salt and fibre-enriched pork nuggets.

Three different seaweeds, namely, Kappaphycus alvarezii, Ulva lactuca and Sargassum tenerrimum, were incorporated separately at 3%, 4% and 5% levels to develop low-salt and fibre-enriched pork nuggets. A total of nine treatments (T1–T9) were compared the following incorporation of different percentages of seaweed powder, alongside a control. All the samples were investigated for physico-chemical parameters (pH, cooking yield and emulsion stability), proximate composition, colour, texture profile analysis and sensory characteristics.

With the incorporation of seaweed powders, the level of salt to be added was reduced in the formulation. All the treatments had higher (p = 0.05) cooking yield (%) and emulsion stability (%) than the control, along with an increase (p = 0.05) in total dietary fibre (TDF), irrespective of the type of seaweed added. Incorporation of seaweed significantly (p = 0.05) increased the hardness and chewiness of the products. On sensory analysis, out of all the treatments, T2 was found to have the highest scores in terms of various sensory attributes and was also found comparable to control. The study shows that based on physicochemical, proximate and sensory properties, out of all the tried levels, 4% Kappaphycus alvarezii powder can be incorporated for the development of low-salt and fibre-enriched pork nuggets.

The study highlighted the use of seaweeds as a functional ingredient in development of low-salt, fibre-enriched pork nuggets. It would result in improving yield and key nutritional and sensory attributes with a simultaneous decrease in the level of salt to be added in processing. Further, it would also provide an opportunity to use underutilized nutrient sources, i.e. seaweeds, which will also help in an overall reduction of the cost of developed products.

The technology for developing pork nuggets using seaweed powders is simple and can be easily adopted by small-scale entrepreneurs and processors. The product developed in his study can have a wider consumer base in terms of superior functionality.

Research on the development of low-salt, fibre-enriched pork nuggets incorporating seaweed powders is very limited. Utilization of seaweeds in meat product formulations represents a promising and innovative approach, aimed at enhancing nutritional profiles while maintaining desirable textural and sensory characteristics. This novel area of study leverages unique functional characteristics of seaweeds, such as high fibre content and natural mineral richness, to create healthier products, which is in consonance with the UN Sustainable Development Goal of Good health and well-being. Exploring the potential of seaweeds aligns with the growing demand for functional meat products alongside addressing consumers’ preference for products with lower sodium content without compromising sensory quality.

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.

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, a_w), instrumental colour and texture profile and sensory attributes.

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, a_w, 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.

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

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

The physical, biomechanical and chemical properties of the composite biodegradable films are examined by their chemical composition, structure, processing conditions and economics. Therefore, the purpose of the study was to develop standard composite biodegradable films by optimizing the process (drying time and temperature) and composition (whey protein concentrate; WPC and sodium alginate; SA).

Composite WPC–SA films were developed using the Box–Behnken design of response surface methodology (RSM), with individual and interactive effects of process variables on the response variables (quality characteristics). Three independent factors at three different levels (WPC: 5–7 g, SA: 0.1–0.5 g and drying temperature: 35°C–45°C) were evaluated for their effects on physical and biomechanical properties, namely, thickness, penetrability, moisture content, water vapor transmission rate (WVTR), density, solubility, transmittance and color variables. The results were analyzed using ANOVA. For each response, second-order polynomial regression models and resulting equations were developed.

The response surface plots were constructed for representing a relationship between process parameters and responses. All responses were optimized as the best and desired, namely, thickness (180 µm), penetrability (7.63 N), moisture (28.05%), WVTR (1.87 mg/m²t), solubility (36.12%), density (1.33 g/ml), transmittance (40.55%), L* value (52.50), a* value (0.35) and b* value (13.70). The regression models exhibited “good fit” of experimental data with a high coefficient of determination. A close agreement was found between experimental and predicted values.

These biodegradable films can be promisingly used in the food packaging system without the problem of disposability.

The composite films with proteins and polysaccharides can be developed, which have improved physical and biomechanical properties.

This paper aims to highlight the candidature of papaya/Carica papaya L. extracts (PLE) and oregano/Origanum vulgare leaves extract (OLE) as novel natural antioxidants, which was further fortified into goat meat nuggets to evaluate quality changes and storage stability at refrigeration temperature (4 ± 1ºC) for 20 days.

Three different products, namely, control (without phyto-extracts), T−1: PLE (0.5 per cent) and T-2: OLE (1.0 per cent) fortified goat meat nuggets, were prepared and subjected for various quality attributes with relation to storage stability.

It was observed that pH significantly (p = 0.14) decreased till 10th day of storage i.e. from 6.49 to 6.32 (control), 6.37 to 6.28 (T−1) and 6.45 to 6.43 (T-2) afterword showed increasing trend till further storage of 20 days in control, as well as treated products. Water activity was non-significant (p = 0.01) on first day of storage and decreased up to 20th day. PLE treated product showed good margin of microbiological protection followed by OLE and least was found in control. L* value showed increasing trend (p = 0.03) throughout storage and ranged from 50.15 to 54.27, while a* values were decreased significantly from 10.36 to 9.06, 10.86 to 9.49 in PLE (p = 0.02) and OLE (p = 0.03), respectively. Sensory panel awarded the highest score for fortified goat meat nuggets, justifying the best quality attributes in term of texture attributes of the treated products. Thus, papaya and oregano leave extracts proved in the extension of shelf life and can be further harvested to develop functional goat meat nuggets.

In search of novel bioactive phyto-extract, meat industry focussed most of the research towards natural anti-oxidants. In the view of same, the present research strategy was planned to examine candidature of Carica papaya L. and OLEs as novel natural antioxidant into meat system during aerobic packaging storage. Goat meat nuggets are amongst the most convenient and famous snack, as well as nutritious meat products, but lacks functional properties. Therefore, with implication of present research at practical level, meat industry can develop function goat meat nuggets by incorporating Carica papaya L. and Origanum vulgare extracts as natural and novel bioactive antioxidants with improved functionality.

This is the first attempt to develop functional goat meat nuggets incorporated with papaya/Carica papaya L. and oregano/OLE. This research can lead to be a pioneer work in meat science.

The purpose of this study is to develop a chicken product that could supply calcium, vitamin E and vitamin C together with high sensory acceptability. The present study was envisaged to develop low-fat chicken patties fortified with calcium, vitamin E and vitamin C without any adverse effects on sensory attributes.

Three different levels of calcium lactate as a source of calcium viz. 1.5, 1.75 and 2.0 per cent, α-tocopherol acetate for vitamin E at 0.019, 0.023 and 0.029 per cent and ascorbic acid for vitamin C at 0.09, 0.12 and 0.15 per cent in low-fat chicken meat patties were tried and the optimum level was standardized based on physico-chemical, proximate and sensory parameters.

The calcium lactate at 1.75 per cent, α-tocopherol acetate at 0.029 per cent and ascorbic acid at 0.15 per cent were found to be optimum on the basis of proximate, physico-chemical and sensory parameters. The textural attributes of the standardized product was comparable to that of the control. The a*, b* and Chroma values for the low-fat chicken patties fortified with calcium, α-tocopherol and ascorbic acid were significantly higher (p < 0.01) than that of the control. The calcium and ascorbic acid concentration of the standardized product was significantly higher (p < 0.01) than that of the control.

The levels in the fortified product were found to be suitable to achieve a 20 per cent RDA of calcium and almost a complete RDA for vitamin C. The research findings demonstrated the development of a single-designer chicken product rich in calcium, vitamin C and vitamin E.

The purpose of this study was to develop functional emu meat nuggets incorporated with finger millet flour (FMF) with high fibre content and improved oxidative stability.

FMF was incorporated at 4, 6 and 8 per cent levels with replacement of emu meat in nuggets formulation and on the basis of various physico-chemical, instrumental colour and sensory parameters, 6 per cent FMF was selected as optimum. The functional emu meat nuggets incorporated with optimum level of FMF as well as control were aerobically packaged in low density polyethylene (LDPE) bags and stored for 21 days at refrigeration (4 ± 1°C) and evaluated for oxidative stability, microbiological quality and sensory attributes at regular interval of 7 days.

The fat content showed significant (p < 0.05) decrease, whereas the crude fibre content increased significantly (p < 0.05) with the increasing levels of incorporation. The sensory scores for all the attributes in 6 per cent FMF-incorporated product were higher than control. During entire storage studies, the thiobarbituric acid reactive substances (TBARS), free fatty acid and peroxide value followed an increasing trend for control as well as treatment product; however, treatment showed a significantly (p < 0.05) lower value than control throughout the storage period. Standard plate count increased significantly (p < 0.05) for control and treatment product, but the counts were lower than the prescribed limits even on 21st day of storage.

The developed products will have functional value by increasing the calcium and dietary fibre content by utilizing the minor cereals. This will be highly beneficial to both the agriculture and meat industry.

The research findings demonstrated the use of FMF in the development of calcium- and fibre-enriched emu meat nuggets with improved oxidative stability.

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.

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.

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.

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

During the past decade few areas of marketing strategy have received more attention than the establishment and implementation of pricing strategies. This emphasis has been due in part to the erosion of purchasing power during the past ten years. Both individual household income and real company profits (profits discounted for the impact of inflation) suffered declines which have only recently been turned around.
