By Products

The fish industry generates by-products that are still nutrient-rich. Its incorporation in pasta production could be an interesting option to get functional food. Therefore, the aim of this study was to compare the nutritional composition, technological properties and sensory quality of two pastas containing tuna and sea bass by-products, separately. Durum wheat semolina and fish by-product concentrates were used in pasta manufacturing. Fatty acids profile, optimal cooking time, texture profile analysis, color, weight gain, swelling index, cooking losses and moisture were determined and compared with a non-containing fish reference. A sensory analysis was also carried out. In general, results showed a higher content of fatty acids in tuna pasta than in sea bass pasta. The texture profile analysis (TPA) showed lower hardness and fracturability in the fish pasta. Cohesiveness was higher in the tuna pasta while sea bass pasta was brighter. Fish incorporation caused a decrease in weight gain and swelling index and an increase in cooking losses. Sensory analysis established differences in homogeneity, typical aroma, fish flavor, fish odor and elasticity. It was concluded that the use of these by-products results in a more nutritious pasta although tuna content should be reduced (<3%) to improve its sensory profile.

Consumers often mix pasteurised meat products from the subgroup of smoked meat with a subgroup of meat products known as canned meat. The aim of this study was therefore to determine their physicochemical parameters and sensory properties of smoked meat and canned meat subgroups of pasteurised meat products on the Slovenian market. Chemical analyses of the content of ash, sodium chloride and phosphates, thiobarbituric acid number (TBA), instrumental measurements of the proximate composition (NIR), colour (CIE L*, a*, b*) and texture (Texture Profile Analysis) as well as the evaluation of sensory properties (Descriptive Analysis Method) were performed on 33 products. The products of smoked meat had a higher content of protein, ash, total phosphates and sodium chloride than the products of canned meat. All products were oxidatively stable (low TBA number). The products of smoked meat were darker (lower L* values) and redder in cross-section (higher a* values), they were tougher, gummier, more difficult to chew, more cohesive and less elastic in texture (Texture Profile Analysis) than the products of canned meat. The panel of experts evaluated the products of both subgroups with a similar average overall impression. Compared to the products of the canned meat, the products of the smoked meat showed worse slice colour uniformity, they contained a higher level of gelatinised connective tissue on the slice, had a worse slice connectivity, the texture of a slice was firmer with coarser fibres, they were saltier, with a less pronounced metallic and rancid aroma and a more pronounced bitter, acidic and odd aroma. Chewiness, gumminess, cohesiveness, hardness and elasticity (texture parameters) loaded strongly on the quality parameters of all products (Factor analysis). Furthermore, linear discriminant analysis confirmed that the products of the subgroups smoked meat and canned meat differ in their physico-chemical and sensory profile.

Effects of added gluten and transglutaminase on microstructure, instrumental texture and sensory characteristics of bread baked with 51% wholemeal oat flour were compared in order to determine how changes in the state of macromolecules – protein and starch – correlate with changes in sensory and instrumental structure. Light microscopy, instrumental texture profile analysis, and descriptive sensory analysis were used to analyse the test breads. Addition of gluten and transglutaminase affected the structure of the protein network and distribution of water between the protein and starch phases. The differences in microstructure were quantified by determining the areas of starch and protein in the micrographs by image analysis. Breads baked with added gluten and water were softer and less gummy than the oat and wheat reference breads in the texture profile analysis. Addition of transglutaminase made the breads harder and gummier than the breads baked without the added enzyme. In the descriptive sensory analysis breads baked with added gluten or added gluten and water were evaluated as more soft and springy than the reference oat bread. Sensory characteristics of bread texture correlated well with the texture and microstructure measured instrumentally.;

Rabbit meat usage in processed products is low. However, rabbit meat raw sausage can be an alternative to increase this meat’s market share. The objective of this study was to determine the effect of blending textured soybean protein and rabbit meat on the texture profile analysis and sensory properties of the chorizo. Five treatments were designed, one control and another four using blends of rabbit meat and textured soybean in ratios of 10, 20, 30 and 40%. Measurements were water activity, texture profile analysis, and color, while a sensory test was conducted at the end of experiments for four treatments. The main results indicate that Aw and pH values decreased (p< 0.05), while b* value increased with storage time (p<0.05). L* value decreased after 7 d vacuum packing, but then increased after 14 d. Treatment with 20% of textured soybean results in less hardness and more springiness. Sensory analysis indicates that there is not significant difference in odor global appearance in all treatments (p>0.05), but color, hardness and taste were different (p<0.05). In conclusion, textured soybean protein can be blended with rabbit meat for processing chorizo. The meat product obtained has sensorial characteristics, a texture profile, Aw and color acceptable for this kind of raw sausage, especially in blends with 20 and 30% of textured soybean protein. Moreover, the blend of these two meat ingredients improved nutritional properties and could therefore be offering as a functional meat product.

Aim: the aim of this study was to determine sensory profile, through the use of just-about-right (JAR) scales and penalty analysis, of Bobolo and Chikwangue from the cassava roots fermented with previously cassava-fermented chips powder (PCFCP). Furthermore, retting time, cyanide content and pasting properties of retted roots were evaluated. Methods: for that, two samples of Bobolo and Chikwangue obtained from two cassava retting methods were studied: a control made from the retting without PCFCP and a product made from retting with PCFCP. Results: retting time was carried out in 48 hours less with PCFCP and 60% of cyanide reduction more than control. No major modifications occurs in pasting properties of paste fermented with PCFCP. The sensory analysis indicated high levels of acceptability for products made from retting with PCFCP. The penalty analysis showed that attributes “too sour” and “too much fermented odor” affected the acceptability of the Bobolo from retting without PCFCP significantly. Conclusion: fermentation of cassava through the use of PCFCP is suitable to improvement of sensory characteristics of fermented cassava by-products.

Morphological Indices

Sensory analysis is the most ancient and inexpensive method of assessing the quality of food products. Consumer demand for the fruit bodies of mushrooms is due to their unique taste and aroma. Profile methods of sensory analysis are used in quality control, for characterising the differences between food products and for determining the impact of various factors on the quality of the test product. The aim of this research is to study the influence of different types of substrates on the character and intensity of arom     a of the dried fruit bodies of Pleurotus ostreatus (Jacq.: Fr.) Kumm. IBK–1535 using the sensory profile method. The substrates for the cultivation of mushrooms were selected from waste from the agricultural and wood processing industries: sunflower husks, wheat straw, waste from the cleaning of seed corn, and sawdust of deciduous trees and oak bark. The preparation and sterilization of substrates was performed according to standard techniques. During the process of cultivation we determined the culture-morphological indices of development of the mycelium: the duration of growth in the substrate, time of appearance of the primordia, the number of formed fruiting bodies of mushrooms, the average biomass of the fruiting bodies. We did not detect any significant differences between substrates in the growth rate of mycelia. The best culture-morphological indices of growth and development of mycelia were identified for the corn waste substrate. This substrate had the greatest number of primordia, while the lowest was for wheat straw. The mycelium of P. ostreatus IBK-1535 was white, fluffy, and denser on substrates of corn waste, sunflower husks and oak bark. The sensory profile analysis was performed according to ISO 6564:1885.1 g of dried fruiting bodies was crushed, placed in glass vials with stoppers and heated to +35…+40 °C for a better emission of volatile compounds. A five person degustation commission was trained to undertake the sensory analysis. First, using sensory analysis, the degustation commission determined the following descriptors of odour for the fruiting bodies of the fungi: mushroom, woody, grassy, sweet, sour. Then the intensity of the aroma of each sample was assessed on a five-point scale. The most characteristic mushroom aroma of the dried fruit bodies was obtained when oak bark was the substrate for cultivation. The samples of mushroom grown on sawdust and waste corn had a similar aroma. The samples obtained for sunflower husk and wheat straw had a slight mushroom aroma with grassy and sour notes. Thus, the use of the sensory profile method of analysis makes it possible to assess the degree of intensity of aroma of fruit bodies of higher edible mushrooms in relation to the conditions of their cultivation without having to use complicated instrumental methods of analysis. Moreover, sensory profile analysis can be used to monitor the odours and aromas of mushrooms, which are cultivated in artificial conditions, for the adjustment of the cultivation process and for conducting a rapid appraisal of the quality of mushroom products.

Hermetia Illucens

At present, there is limited knowledge about the possible utilization of the fat fraction derived from Hermetia illucens (HI) larvae processing. The objective of the present study was to evaluate the replacement of soybean oil with HI larvae fat in broiler finisher diet, on the quality and sensory traits of their meat. At 21 days of age, 120 male broiler chickens were randomly allocated to three experimental groups (5 replicates and 8 birds/pen): a basal control diet (C), and two groups in which either 50% or 100% of the soybean oil was replaced with HI larvae fat (the HI50 and HI100 group, respectively). At day 48, 15 birds (3 birds/pen) per group were slaughtered, and breasts and legs were excised and used for meat quality evaluations. Breast and leg physical meat quality, nutritional composition and sensory profile remained substantially unaffected by the dietary treatments. In contrast, the dietary incorporation of HI larvae fat modified the fatty acid (FA) profile of both the breast and leg meat cuts: the proportion of saturated fatty acids increased (p < 0.0001) to the detriment of the polyunsaturated (PUFA) fraction (p < 0.0001). Moreover, the meat n-6/n-3 ratio increased in the HI50 and HI100 groups compared to the C group. HI larvae fat dietary inclusion decreased the monounsaturated fatty acids in the breast (p = 0.0012) but not in the leg meat. Further research should focus on the improvement of the FA profile of the larvae through substrate modulation, or by combining HI larvae with a PUFA-rich feedstuff in feed formulations.
