The aim of this work was to investigate the influence of different percentages of Carboxymethyl Cellulose (CMC) and Soy Protein Isolate (SPI) as coating material films for potato pellet chips during deep-fat frying on fat uptake, and sensory properties. Coating solutions of 2%, 6%, 10% and 14% w/v were prepared and heated to 90 ºC for 5 minutes then cooled. Samples were dipped in the coating solutions followed by air drying. The treatments were fried and analyzed for fat uptake and moisture retention. Sensorial attributes were also measured. The results obtained have shown that all coating treatments were reduced oil uptake during deep fat frying. The 10% was the most effective level in reducing fat uptake for both coating films. SPI coating films was reducing fat uptake more than CMC for all levels. All samples were found to improve all sensorial features of potato pellet chips compared to control.
In an attempt to improve the chemical, physical and sensory properties of beef burgers containing 11.5–13.7% fat, trials were carried out on eight experimental burger formulations containing carrageenan (0.5%), texturized soya (1.5%) and trisodium phosphate (0.5%), either alone or in different combinations, and compared with a control prepared only with the addition of salt and water. The data obtained were analyzed using a complete randomized design to study the effect of treatments on the proximate composition, thiobarbituric acid reactive substances (TBARS) value, percentage cooking loss, percentage diameter loss and sensory evaluation. The significant difference of the mean was determined using the least significant difference method. Although initial weight, cooked weight, initial diameter length and cooked diameter length were analyzed using means ± standard error. Analyses revealed unexpected interactions between some of the ingredients, the nature of which was not investigated. Results showed that the addition of carrageenan alone improved crude protein content, juiciness and overall acceptability of the beef burger, but it affected the appearance negatively, although there was no significant effect on diameter loss and thickness loss when compared with the control. Beef burger prepared with the addition of texturized soya alone increased moisture binding and protein level, while it lowered flavor score compared with the control. With respect to the oxidative rancidity, TBARS value was found higher for the market sample; this value was significantly lower with the addition of combination of texturized soya and trisodium phosphate. It has been found that the addition of a combination of carrageenan, texturized soya and trisodium phosphate reduced the cooking loss compared with the control, while there was no significant effect on the diameter loss and thickness loss of all treatments. It was also found that the combination of carrageenan, texturized soya and trisodium phosphate improved all sensory attributes and improved protein contents compared with the control. The sensory scores were highly correlated with each other. No significant correlations were found between moisture percentage and cooking loss together and sensory attributes, while there were high correlations between the TBARS and fat percentage with sensory attributes. PRACTICAL APPLICATIONS Reducing the fat content of beef burgers can make a significant contribution to human health and ensure the continuing popularity of this type of convenience food around the world. However, merely using leaner meat does not provide a product with the necessary quality attributes. So, practically, it has been found that the addition of carrageenan, texturized soya and trisodium phosphate can improve the beef burger sensory properties as a whole, including the appearance, color, flavor, tenderness, juiciness and overall acceptability. In addition, the oxidative rancidity (thiobarbituric acid reactive substances) of the product can also, be...
This work aimed at determining the maximum acceptable level of wheat germ that can be added to one of homemade biscuits in Jordan, studying some chemical and sensory properties of this product, moreover, studying the effect of storage time after two months at room temperature on the sensory parameters of this product. The results showed that the addition of wheat germ in biscuit making at level of 20% (w/w) enhanced the nutritional value by increasing protein and total mineral content, as well as decreasing fat, total carbohydrates and total calories. The acceptability of sensory characteristics was improved by this fortification immediately after preparation and during storage.
Six mortadella treatments were prepared for studying the effect of olive leaf extract (OLE) at a level of 240 mg OLE/100 g meat as nitrite alternative on the color and sensory characteristics. These treatments were: control with the addition of 120 ppm sodium nitrite only, and the second one with the addition of 240 mg OLE/100 g meat but without the addition of sodium nitrite as a negative control, the other four treatments were combination of 240 mg OLE/100 g meat with 80, 60, 40 and 20 ppm sodium nitrite, respectively. All samples were stored at 5 °C for 1, 3, 6, 9, and 12 weeks.There were no significance differences (P > 0.05) between all mortadella treatments regarding their proximate parameters. Hunter lightness (L), redness (a), and yellowness (b) color, and sensory attributes including the appearance, color, tenderness, juiciness, flavor, and overall acceptability showed that 80 and 60 ppm nitrite in combination with OLE at 240 mg/100 g meat had the best results in comparison with the other four treatments indicating an additive combined effect of the OLE with nitrite that enhanced mortadella characteristics.These results revealed the ability to substitute 50% of the used nitrite in mortadella stored at 5 °C when using combinations of 60 ppm nitrite with 240 mg OLE/100 g meat.
The objective of this study was to determine the effect of different percentages of whey protein and whey protein isolate as coating material films for potato pellet chips during deep-fat frying on fat uptake, and sensory properties. Coating solutions of 1%, 3%, 5% and 7% w/v were prepared and heated to 90ºC for 5 minutes then cooled. Samples were dipped in the coating solutions followed by air drying. The treatments were fried and analyzed for fat uptake and moisture retention. Sensorial attributes were also measured. It was observed that all coating treatments were reduced oil uptake during deep fat frying. The 5% was the most effective level in reducing fat uptake for both coating films. Whey protein isolate coating films was reducing fat uptake more than whey protein for all levels. All coated treatments were improved all sensorial features of potato pellets chips compared to control.
