In recent years, global demand for functional foods grew tremendously due to the rising trend of health-conscious consumers. Driven by increased awareness of probiotic products, consumption of yogurt drink is gaining popularity across all age groups. In the present study, the authors aimed to assess sensorial, nutritional and technological properties of synbiotic yogurt drink enriched with prebiotic inulin.

Sensory analysis, proximate compositions, viscosity, viable count and DPPH radical scavenging activity were examined in control (without inulin) and 3 variants of inulin-supplemented synbiotic yogurt drink, namely F1 (4%, inulin), F2 (4.5% inulin) and F3 (5% inulin).

Evaluated by 75 consumer panellists on 9-point hedonic scales, F3 showed significantly (p < 0.05) higher overall acceptability (5.79 ± 1.94) compared to control. In addition to lower calorie content (36.52 kcal/100 ml), nutritional and technological properties of F3 [total dietary fibre content (4.03 ± 0.04 g/100 ml), viscosity (28 ± 6.93 cP), viable count (87.00 ± 4.00 × 106 CFU/ml S. thermophilus; 14.67 ± 3.51 × 106 CFU/ml L. bulgaricus) and antioxidant activity (50.40 ± 1.80%)] were significantly (p < 0.05) improved compared to control. Remarkably, the new formulation complied with nutrient criteria for Healthier Choice Logo Malaysia in addition to meeting requirements for “low fat” and “high dietary fibre” contents according to Malaysia Guide to Nutrition Labelling and Claims. Hence, we conclude that 5% inulin improved nutritional and technological characteristic in synbiotic yogurt drink without compromising consumers' acceptance.

This novel study showcases the incorporation of prebiotic inulin in the development of synbiotic yogurt drink. Remarkably, this new formulation complied with the nutrient criteria for Healthier Choice Logo Malaysia in addition to meeting the requirements for “low fat” and “high dietary fibre” contents according to Malaysia Guide to Nutrition Labelling and Claims.

The purpose of this paper is to explore the variety of food in which it has been applied as a prebiotic and functional ingredient, the concentrations used there in, the tests that have been conducted on these fortified foods and briefly reviews the history and characteristics of inulin.

The review included articles from 1999-2013. The papers which reported inulin concentrations used, the purpose of the application and tests on final product, were mainly selected. Articles were collected in electronic databases such as Elsevier-Science Direct, Emerald, Springer Link, Wiley and Redalyc.

The interaction inulin-food with different food matrices is complex, and is not always technologically favorable for the product. Moreover, additional to evaluations of sensory, physicochemical and rheological characteristics, it is essential to carry out measurements in the food, of such characteristics as prebiotic content, and prebiotic activity in vivo and in vitro, and assess potential adverse reactions in order to define suitable doses of consumption.

The paper highlights the importance of conducting in vitro and in vivo testing of potential prebiotic inulin-supplemented food in order to define dose that benefit health and do not cause unacceptable gastrointestinal distress.

The purpose of this study is to evaluate the effects of partial or total substitution of milk fat by various levels of jojoba oil on the nutritional, physicochemical and sensory properties of Domiati cheese during cold storage at 6°C for 45 days.

The fat percentage of milk used for cheese manufacture was standardized to 4% fat. Five formulas were produced by replacing milk fat with 0%, 25%, 50%, 75% and 100% of jojoba oil, respectively. The physicochemical and sensory properties of cheese samples at 0, 15, 30 and 45th days of cold store were evaluated.

No significant differences in moisture, fat, protein and acidity values amongst the control samples and those samples supplemented with different concentrations of jojoba oil. Significant differences (p = 0.05) in total volatile fatty acids were detected amongst experimental cheese samples. The highest values were recorded for control sample containing 100% milk fat, while the lowest values were recorded for cheese sample containing 100% jojoba oil (p = 0.05). Total nitrogen (TN), water-soluble nitrogen (WSN) and trichloroacetic acid soluble nitrogen (TCA-SN) levels of experimental cheeses were nearly same as for control. The results of fatty acids profile showed that jojoba oil has a unique structure of straight monounsaturated alcohols. Significantly (p = 0.05), the highest cholesterol content was recorded for control sample containing 100% milk fat; however, the lowest (p = 0.05) value was recorded for cheese sample containing 100% jojoba oil. At the end time of storage period, control sample manufactured with 100% milk fat had the highest (p = 0.05) values of free fatty acids, peroxide and thiobarbituric acid, while the lowest values were recorded for cheese sample with 100% jojoba oil as a source of fat. The sensory evaluation results demonstrated that blending milk fat with jojoba oil improved the sensory properties of Domiati cheese.

It is concluded that substitution of 25%, 50%, 75% and 100% of milk fat by equal amounts of jojoba oil enhanced the nutritional and sensory characteristics of Domiati cheese.

It is concluded that Domiati cheese formulated with substitution of 25%, 50%, 75% and 100% of milk fat by equal amounts of jojoba oil enhanced the nutritional characteristics and improved the sensory properties of produced cheese.

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.

This paper aims to evaluate the effects of inulin (3 per cent), chitosan (1 per cent) and carrageenan (0.5 per cent) addition on the physico-chemical, sensory and textural attributes of restructured goat meat products. Health conscious consumers are much more interested in product with added health benefit. Keeping this in mind, this study was undertaken to find out effective ingredient for low fat restructured goat meat product.

Formulation for restructured goat meat blocks was optimized and four different formulation containing different ingredients, namely, control, inulin (3 per cent), chitosan (1 per cent) and carrageenan (0.5 per cent), were used to find out best ingredient for healthier goat meat product and various physicochemical and sensory properties of the product were evaluated.

Results showed that addition of carrageenan improved (p < 0.01) the product yield (86.0 per cent) significantly. The proximate composition, expressible water and water activity were similar. The moisture retention percentage was significantly (p < 0.01) reduced (86.0 per cent) due to addition of inulin. Carrageenan significantly (p < 0.05) increased the lightness (42.4) and yellowness (10) values. Significantly (p < 0.05) lower shear force values were observed in inulin (0.5) and chitosan (0.4) containing samples than control (0.7 kg/1.5 cm²). Hardness values were significantly (p < 0.05) lower in restructured product containing chitosan (56.1 N/cm²) and carrageenan (59.4 N/cm²). Similarly, springiness values were significantly (p < 0.05) lower (0.7 vs 0.8 cm) in carrageenan containing product. Inulin, chitosan and carrageenan did not significantly influence the sensory attributes of restructured goat meat product. It is concluded that inulin, chitosan and carrageenan could be used to improve technological and functional attributes of the healthier restructured goat meat product.

Future research may benefit from efforts to modify shelf life of the product by modifying packaging condition.

The healthier meat-based restructured goat meat product has been developed, and the effect on its quality characteristics have been extensively examined, limited research has focused on this aspect.

Outlines some of the reasons behind the development of vegetable oil cheese and critically questions the whole basis and need for such cheese‐type or substitute products. Evaluates two of these new products and compares them with mild and low‐fat Cheddar cheese by using a semi‐trained sensory panel. Finds no significant differences between the appearance of the cheeses but finds differences for texture and flavour. Finds the vegetable oil cheeses to have a flavour similar to mild Cheddar, while the product made with sunflower oil has a soft and crumbly texture compared with that of cheese made from rapeseed oil.

There are few processed food products which do not contain one or more hydrocolloids in their formulation. Hydrocolloids are generally polysaccharide extracts, obtained from plants, which have a great affinity for water at relatively low concentrations (considerably less than 1%) and produce highly viscous or gelled systems. Their vital role in food products is to provide a degree of bulk structure sufficient to stabilise the product, improve its consumer appeal, and extend its shelf life.
