Abstract:The physicochemical, rheological and sensory properties during the storage of Kariesh cheeses made with 0.1, 0.2, 0.3, 0.4 or 0.5 g wheat bran/100 g milk were evaluated at 0, 7 and 15 days. The cheeses with 0.5 g wheat bran/100 g milk had a significantly (P < 0.01) higher yield and moisture content, and lower pH and protein content than the control. No significant differences (P > 0.01) in salt and ash contents were observed among the cheeses studied. Texture profile analysis showed that the rheological charac… Show more
“…This indicated that the increase in yield might be due to the presence of fiber in karish cheese made by mushroom mycelium. Similar finding was previously found by other authors (Ahmed et al, 2005;Abd El-Hamid et al (2016); Zayan, 2016;Basiony et al, 2018). Onwulats (2008) found that dietary fiber absorbed water from the environment.…”

Karish cheese was manufactured commercially by adding starter cultures and rennet. In this study, three species of Pleurotus mushroom mycelium were examined in making Karish cheese from skim buffalo's milk. Yield, chemical, sensory and rheological properties of cheese manufactured by homogenized P. ostreatus (HPO), P. florida (HPF) and P. eryngii (HPE) were evaluated. Results showed decrease in the coagulation time by increasing the concentration of homogenized oyster mushroom mycelium. Karish cheese made by HPE resulted in the highest overall yield, followed by HPF, when compared with cheese manufactured by rennet, which had the lowest cheese yield. Chemical analysis illustrated that Karish cheese with homogenized Pleurotus mycelium was nearly of the same constitutional values, in addition to fiber. The rheological characteristics improved significantly in the fresh cheese samples made with HPO, HPF and HPE and during storage. Sensory evaluation showed that Karish cheeses made with HPO, HPF and HPE were more acceptable by the panelists than Karish made by starter or rennet.

“…The addition of GPP modified the sensory attributes of cheeses. Generally, the addition of fibers or by-products exert a strong effect on the sensory parameters of dairy products [ 37 , 52 ]. In this study, except for sweet and bitter that scored similar values in all trials, all other attributes evaluated were consistently influenced by the addition of GPP.…”
An innovative ovine cheese enriched with red grape pomace powder (GPP) was produced to improve the functional properties of Vastedda cheese typology. Vastedda cheese making was performed adding GPP and four selected Lactococcus lactis strains (Mise36, Mise94, Mise169 and Mise190). For each strain, 40 L of pasteurized ewe’s milk was divided into two aliquots representing control and experimental trials. Control cheese (CC) production did not contain GPP, while the experimental cheese (EC) production was enriched with 1% (w/w) GPP. GPP did not slow down starter development and acid generation. Plate counts and randomly amplified polymorphic DNA (RAPD)-PCR analysis confirmed the dominance of the starters in all trials. The evolution of the physicochemical parameters showed that EC productions were characterized by lower fat content, higher protein content, and higher values of secondary lipid oxidation. Sensory evaluation indicated that the cheeses produced with the strain Mise94 were those more appreciated by the judges. Thus, the last cheeses were investigated for some functional aspects: GPP enrichment significantly increased antioxidant activity and lipoperoxyl radical scavenger capacity, confirming that grape polyphenol inclusion in cheese represents an optimal strategy for the valorization of ovine cheeses as well as winemaking industry by-products.
“…The less soluble samples like Br-SC, Art-SC, and the two grape pomace powder cheeses investigated were also the least juicy (scores from 3 to 4.5). In the literature, several examples of the effects of the water binding capacity of by-products on texture parameters and tactile sensation when incorporated into different foods (i.e., bakery, dairy, and meat products) have been reported [ 11 , 25 , 26 , 27 ].…”

“…Marchiani et al [ 10 ] assessed the physicochemical and nutritional quality of grape pomace powder to fortify semi-hard cheese. Abd Elhamid [ 11 ] proposed the incorporation of wheat bran in Kariesh cheese.…”
In this work, spreadable cheese was enriched with flours from by-products (red and white grape pomace, tomato peel, broccoli, corn bran, and artichokes) as sources of fibres and antioxidant compounds. The physicochemical and the sensory properties of all the cheese samples were analysed. Results revealed that total phenolic content, flavonoids, and antioxidant activity of samples containing grape pomace significantly increased, followed by broccoli, artichoke, corn bran, and tomato peel by-products, compared to the control cheese. Specifically, cheeses containing white and red grape pomace recorded high phenolic content (2.74 ± 0.04 and 2.34 ± 0.15 mg GAEs/g dw, respectively) compared to the control (0.66 mg GAEs/g dw).
