Revitalizing traditional Turkish tort cheese into spreadable form: Enhancing bioactive and sensory attributes with utilization of carob molasses pulp that is a food waste.

Tort cheese is a traditional cheese that is a gastronomically valuable product, especially in the Mediterranean Region of Turkey, obtained by prolonged boiling of whey, which is one of the most important dairy byproducts. Due to the difficulty of production and its short shelf life, this cheese, which is produced in limited quantities and has low nutritional value, is among the forgotten products. In this study, a spreadable new cheese formulation was developed to increase the edibility and nutritional value of traditional Tort cheese. In this context, pulp (carob molasses pulp (CMP)) from carob molasses production was added to the cheese in different proportions (5%, 10%, and 15%), and some physicochemical, textural, and sensory properties of the cheeses were examined. As a result of the research, it was determined that the addition of CMP caused a decrease in the pH, fat, and protein content of the cheeses, while significantly increasing the dry matter, acidity, ash, carbohydrate, antioxidant activity, and total phenolic content. With CMP addition, the hardness and water-holding capacity of the cheeses increased, while spreadability, adhesiveness, and syneresis decreased. As the concentration of CMP increased, the L* and b* values decreased, while the a* value increased. In terms of sensory properties, the least preferred sample was the control, while the sample with 5% CMP addition, which is the most spreadable cheese, was the most preferred. As a result, a new product with lower fat content that was more durable and stable, rich in bioactive properties, and with improved sensory attributes was developed.

Development and Optimization of Vegan Cheese Spread: Studies in Rheology and Microstructure

ABSTRACT Vegan foods are growing in the market owing to various factors such as awareness about humane production of food, sustainability and health. In this study, a vegan cheese spread was developed with main ingredients being Jackfruit seed powder, cashew kernels and sunflower oil. The product had an improved nutritional profile as compared to the counterparts in the market providing fat content at 18.19 ± 0.52 g, carbohydrates at 8.31 ± 0.58 g, dietary fiber at 5.15 ± 0.45 g, and protein at 8.82 ± 0.09 per 100 g. Rheological and microstructure studies indicated that the food matrix was undergoing dynamic rearrangements at the molecular level on storage, but was appearing stable to the eye of the observer. Product attributes scored 8 points and higher on the hedonic scale of sensory evaluation. Practical implication of this research venture is that a vegan cheese spread has been developed and characterized on laboratory scale and can be further scaled up.

Can a functional cheese spread incorporating Akkermansia muciniphila deliver beneficial physicochemical and biological properties while enhancing probiotic stability and viability during aerobic storage and in vitro digestion?

In the present study, next generation probiotic Akkermansia muciniphila was incorporated into a dairy matrix containing Portuguese whey cheese and Greek-style yoghurt in a proportion of 3.5:1, respectively. Subsequently, this innovative food was characterized in terms of microbiological and physicochemical parameters, total phenolic content and antioxidant, antidiabetic, and antihypertensive activities, as well as its protective effect on A. muciniphila viability during 21 d of refrigerated aerobic storage and when subjected to simulated gastrointestinal passage. The probiotic cheese spread displayed high microbiological quality, low total phenolic content (0.36 mg gallic acid equivalents/g of dried cheese) and interesting biological activities, including antidiabetic (98.10% α-glucosidase inhibition) and antihypertensive (49.18% angiotensin converting enzyme inhibition). Simultaneously, this food ensured a high A. muciniphila viability (>108 CFU/g) during 21 d of refrigerated aerobic storage with subsequent in vitro digestion. Additionally, this probiotic cheese presented a similar profile in terms of texture, color, water activity and pH when compared to the cheese control (without A. muciniphila), suggesting a potentially high acceptance among consumers. In conclusion, the developed cheese spread seems to be a promising and suitable food vector to safeguard A. muciniphila viability during refrigerated aerobic storage for at least 21 d with subsequent gastrointestinal passage.

Development and Evaluation of Value-Added Cheese Spread using Red Cabbage Microgreens and Flaxseeds

Abstract: Microgreens, the young seedlings of vegetables and herbs, are gaining popularity for their distinct flavors , superior nutritional content and positive impact on gut health. Red cabbage microgreens (RCMG) stand out with remarkable vitamin C (147mg/100g) and other antioxidant rich phytochemicals content. Flax seeds (FS), known for their versatility in food offer cardiovascular benefits with high levels of alpha-linolenic acid and dietary fiber. This study aimed to develop value-added cheese spread using RCMG and FS, employing pre-preparation treatments like blanching and roasting. Three variations (V1, V2, V3) with varying RCMG and FS compositions were developed and evaluated. Commercially available cheese spread was used as the control (basic). Sensory evaluation, conducted by 46 semi-trained panelists using a 9-point Hedonic rating scale, revealed V1 (RCMG-30%, FS-6%) as the most accepted variation with good spreadability compared to the basic cheese spread. Value-added cheese spread showed no signs of spoilage in 30 days shelf life check under refrigeration. This study indicates the successful incorporation of Red Cabbage microgreens and Flaxseeds into the cheese spread with good sensory acceptability.

Effect of fat on physicochemical, rheological, textural and sensory properties of Ricotta cheese spreads

SummaryThe effect of different fat contents of milk and cheese whey mixture (20:80) on physicochemical, rheological and sensory properties of Ricotta cheese spread (RCS) was evaluated. Four types of product such as no‐fat milk (NFM)‐RCS, low‐fat milk (LFM)‐RCS, medium‐fat milk (MFM)‐RCS and full‐fat milk (FFM)‐RCS were prepared from Ricotta cheese curd added with salt (1.5%) and guar gum (0.4%). The NFM‐RCS had higher (P < 0.05) protein, ash, acidity, dynamic modulus (G' and G"), critical stress, firmness, work of shear, stickiness, work of adhesion values and lower fat, and pH, L*, a*, b* values when compared with LFM‐, MFM‐ and FFM‐RCS. Except spreadability, highest sensory scores for all other attributes were found in MFM‐RCS when compared with other experimental samples. This study indicated that increase in fat content or decrease in protein content of RCS samples produced lower viscoelastic modulus values, firmness, stickiness, adhesiveness and higher spreadability, yield, solids recovery and highly acceptable sensory characteristics.

Thermosonication as an effective substitution for fusion in Brazilian cheese spread (Requeijão Cremoso) manufacturing: The effect of ultrasonic power on technological properties

In this initial study, the impact of thermosonication as an alternative to the traditional fusion in Brazilian cheese spread (Requeijão Cremoso) manufacture was investigated. The effect of ultrasound (US) power was evaluated considering various aspects such as gross composition, microstructure, texture, rheology, color, fatty acid composition, and volatile compounds. A 13 mm US probe operating at 20 kHz was used. The experiment involved different US power levels (200, 400, and 600 W) at 85 °C for 1 min, and results were compared to the conventional process in the same conditions (85 °C for 1 min, control treatment). The texture became softer as ultrasound power increased from 200 to 600 W, which was attributed to structural changes within the protein and lipid matrix. The color of the cheese spread also underwent noticeable changes for all US treatments, and treatment at 600 W resulted in increased lightness but reduced color intensity. Moreover, the fatty acid composition of the cheese spread showed variations with different US power, with samples treated at 600 W showing lower concentrations of saturated and unsaturated fatty acids, as well as lower atherogenicity and thrombogenicity indexes, indicating a potentially healthier product. Volatile compounds were also influenced by US, with less compounds being identified at higher powers, especially at 600 W. This could indicate possible degradation, which should be evaluated in further studies regarding US treatment effects on consumer perception. Hence, this initial work demonstrated that thermosonication might be interesting in the manufacture of Brazilian cheese spread, since it can be used to manipulate the texture, color and aroma of the product in order to improve its quality parameters.

Применение рапсового масла в составе сливочно-растительных спредов

Dairy spreads are popular all over the world. However, the Russian market of dairy spreads should rely both on the modern concept of healthy nutrition and the domestic strategy for improving the quality of food products. The authors optimized the fatty component of cream cheese spreads by adding rapeseed oil. The article introduces its fatty acid composition and effect on the structural, mechanical, physical, chemical, and sensory indicators of the finished product. The indicial cream cheese vegetable spread had a fat mass fraction of 72.5 %; the share of rapeseed oil added to the fat phase was 10–40 %. The rapeseed oil had no negative impact on the sensory profile of the spread. However, as the proportion of rapeseed oil increased, the structural and mechanical properties deteriorated. The consistency became too soft, which made it difficult to cut the mass into bricks. If the share of rapeseed oil exceeded 10 %, the spread had to be packaged in plastic boxes. The article contains some recommendations on how to obtain the optimal consistency, structural properties, and consumer appeal of the new cream cheese vegetable spread.

The Physicochemical Characterization, Fatty Acid Profile, and Nutritional Indices of the Greek Traditional Cheese “Tsalafouti”

Tsalafouti cheese, a traditional Greek spreadable cheese, has experienced remarkable popularity over the last decade due to the strong dairy production heritage links that it presents, alongside the special nutritional and sensory attributes that it holds. The aim of this study was to chemically characterize the Greek cheese Tsalafouti, with a special focus on its fatty acid profile and the potential nutritional effect it may have. Standard methods were used to assess the physicochemical profile of Tsalafouti cheese, while a fatty acid profile was determined using gas chromatography. The analysis revealed average values, including a pH of 3.94, moisture content of 75.05%, protein content of 8.86%, and fat content of 11.3%. The fatty acid profile highlighted the predominance of health-important fatty acids, such as oleic acid, known for its well-established health benefits. Additionally, the health lipid indices of Tsalafouti were assessed by calculating the atherogenicity index (IA), the thrombogenicity index (IT), the ratio of hypocholesterolemic to hypercholesterolemic fatty acids (HH), the health-promoting index (HPI), and the PUFA-n-6/PUFA-n-3 ratio. The values of these indices indicate the quality concerning proatherogenicity, prothrombogenicity, and the risk of cardiovascular issues. Notably, all the above health indicators are consistent with known health effects. Importantly, the ratio of ω6/ω3 fatty acids aligns with the nutritional recommendations of the World Health Organization. Based on these results, Tsalafouti cheese emerges as a low-fat product and source of protein with potential functional properties, distinguishing itself from other cheeses in the market.

Profile Assessment of Bioactive Peptides in the Greek Traditional Cheese “Tsalafouti”

In the Greek regions of Agrafa and Tzoumerka, Tsalafouti, a traditional spreadable cheese made from goat’s and sheep’s milk is produced. This product has emerged in recent years as a result of the campaign to acquire Geographical Indication. This study aimed to assess the biopeptide profile of Tsalafouti cheese in order to highlight its nutritional value. Using HPLC-MS, bioactive peptides in Tsalafouti cheese samples were identified and classified according to their bioactivity. The biopeptides detected are known to present antibacterial, anti-diabetic, anti-hypertensive, anti-thrombotic, antioxidant, and immunomodulatory activities, while ACE enzyme and dipeptidyl-4 (DPP-IV) inhibitors were also identified. Based on these results, Tsalafouti cheese presents an interesting bioactive peptides profile that may act as special motivation for consumers to choose this specific cheese.

Design of prebiotic cheese spreads enriched with biologically active compounds

The development of functional foods providing health benefits above the basic nutritional needs is of growing interest to the food industry. This research aimed to: design fresh prebiotic cheese spreads enriched with agave inulin (AI), thyme (Thymus callieri Borbás ex Velen.) and hawthorn fruit (Crataegus monogyna Jacq.) as plant sources of biologically active compounds; observe the physicochemical and microbiological changes in the cheese during storage at 4°C for 35 days; evaluate the sensory characteristics of the new functional products. Therefore, five experimental groups of fresh cheese spreads were prepared – a control; 1% AI + 0.2% thyme; 2% AI + 0.2% thyme; 1% AI + 0.4% hawthorn fruit and 2% AI + 0.4% hawthorn fruit. During the storage, pH in all experimental groups gradually decreased (reaching values between 4.17 and 4.25 on the 35th day), which corresponded to the increasing titratable acidity (reaching values from 146.30°T to 152.51°T on the 35th day). The application of thyme and hawthorn fruit did not reduce the total plate count (mesophilic aerobic and facultative anaerobic microorganisms) and yeasts; however, during the storage period the addition of agave inulin stimulated the growth of lactic acid bacteria in the treated samples compared to the control.

Technology Development to incorporate Onion (Allium cepa L) oil as a functional ingredient in Cheese spread

The incorporation of functional ingredients in cheese is a new technology application in the food industry. Onion oil is considered a functional oil which is obtained by cold pressing f onion. These oils were incorporated as a functional ingredient in a percentage of 0.3 ml/Kg, 0.35 ml/Kg, 0.40 ml/Kg, and 0.45 ml/Kg and named T1 to T4 respectively and T0 as a control sample with pure water while maintaining the standard process. Prepared samples were poured into 175 ml glass bottles and kept for sensory, chemical, and microbiological analyses at room temperature and then chilled. The sensory attributes were examined using the 5-point hedonic test. Except for taste and appearance, no significant differences in qualitative attributes were identified in all samples. To assess the shelf life microbiological characteristics such as total plate count, yeast and mould, and coliforms, as well as chemical data such as pH, moisture content, and titratable acidity were tested. The onion oil sample T4 showed good sensory and chemical attributes for cheese and therefore, it can be concluded that the functional onion oil incorporation technology is useful for producing a better cheese spread for the market.

Production of spread cheese by incorporating micro-encapsulated pepper oil with corn oil

The incorporation of functional ingredients in cheese is a new technology application in the food industry. Black pepper oil and corn oil were purchased from commercial stores and micro-encapsulated with the 0:0 g, 15:0 g, 0:15 g, 7.5:7.5 g named as T1 to T4 respectively and added into the cheese while maintaining the standard process. Prepared samples were put into 175 ml glass bottles and kept for sensory, chemical, and microbiological analyses at room temperature and then chilled. The sensory attributes were examined using the hedonic test. The exception of taste, no significant differences in qualitative attributes was identified in all samples. To assess the shelf life of the product designed for marketability, measurements were made on a regular basis for microbiological characteristics such as total plate count, yeast and molds, and coliforms, as well as chemical data such as pH, moisture content, and titratable acidity. The micro-encapsulated products showed a minimum change in the sensory and chemical attributes therefore, it can be concluded that the microencapsulation technology is useful to produce a better spread cheese.

Optimizing quality and mixing performance of processed cheese spread using a mechanical universal disperser

Processed cheese spread (PCS) is currently experiencing rapid growth and is recognised as a prominent segment within the cheese‐based product industry worldwide. This type of cheese spread is produced by comminuting and blending natural cheese of varying ages and degrees of maturity, along with other ingredients, to achieve a homogeneous plastic mass. The high viscosity of PCS necessitates thorough mixing and blending, posing a challenge for cheese processors. In this study, a mechanical unit known as a universal disperser was utilised to prepare PCS. The study aimed to evaluate the impact of different processing parameters on the quality of the final product. Response surface methodology (RSM) was employed to design the experiment and optimise the process accordingly. The experiment involved conducting trials at three distinct melting temperatures: 50, 65 and 80 °C. The impeller speed used for blending the content was set at three levels: 10 000, 15 000 and 20 000 r.p.m. Responses, such as mixing index, mixing time, power consumption, spreadability, and overall acceptability, were recorded. Based on the findings, it was concluded that by employing the optimal parameters, a high‐quality PCS with a desirable overall acceptability score of 8.3 could be achieved while also meeting the desired mixing performance.

The Development of a Novel Sodium Alginate-Based Edible Active Hydrogel Coating and Its Application on Traditional Greek Spreadable Cheese.

The necessity of reducing the greenhouse effect by decreasing the carbon dioxide fingerprint directed the food packaging technology to use biobased raw materials. Alginates, which are derived from brown algae species, are one of the most promising biobased biopolymers for the development of edible active coatings capable of protecting food from oxidation/bacterial spoilage. In this study, sodium alginate, which was plasticized with glycerol and mixed with a biobased thymol/natural halloysite nanohybrid, was used to develop novel edible active coatings. Nanocomposite coatings were also developed in this project by mixing pure halloysite with sodium alginate/glycerol matrix and were used as reference material for comparison reasons. Instrumental analysis indicated a higher compatibility of a thymol/halloysite nanohybrid with a sodium alginate/glycerol matrix compared to pure halloysite with a sodium alginate/glycerol matrix. Increased compatibility resulted in improved tensile properties, water/oxygen barrier properties, and total antioxidant activity. These edible active coatings were applied to traditional Greek spread cheese and showed a reduction in the mesophilic microbial population over one log10 unit (cfu/g) compared to uncoated cheese. Moreover, the reduction in the mesophilic microbial population increased with the increase in halloysite and thymol content, indicating such sodium alginate/glycerol/thymol/halloysite hydrogels as promising edible active coatings for dairy products.

Monitoring of polyphosphate levels in animal source products collected in Italy by means of ion chromatography with suppressed conductivity detection.

Polyphosphates (PPs) constitute a class of food additives widely used due to their ability to exercise different useful activities. The food safety concern about the use of PPs in food is both the possible non-declared addition and some health effects, such as bile duct stones, decrease in oligo-element absorption, and allergic reactions in susceptible people. In this study, an analytical method based on ion chromatography with conductivity detection was applied for the detection and quantification of PPs in 238 samples of animal-derived products such as meat, dairy, and fish products. A contribution to risk assessment was also included. The monitoring confirmed the absence of non-compliant results. All concentrations of PPs were indeed lower than the legal limits set in European Regulation No. 1333/2008. Moreover, no residue of PPs was detected (> limit of quantification: 0.09 g kg-1) in samples where it was not reported on the product label. No PPs were detected in mollusks, meat-based preparations, semi-ripened, unripened, and spun paste cheese, while they are widely used in surimi, with concentrations in the range of 0.1-0.5 g kg-1. The highest concentrations were quantified in a würstel sample (4.7±0.3 g kg-1) and a spreadable cheese sample (8.9±0.7 g kg-1). Considering that the high exposure scenario together with a very susceptible population group (toddlers) were taken into account for this risk exposure study and that the highest admissible daily intake obtained was equal to 10.4%, the assessment demonstrated that the actual use of PPs in food does not pose a risk for food safety.

Time-intensity profile and relationship with consumer acceptability of processed cheese spread

Creamy “requeijão” is the commercially most prominent processed cheese spread in Brazil. The time intensity analysis is important to provide how the flavor behavior is for the consumers during the food ingestion and is used in order to obtain the temporal profile of an attribute in a certain product. In the present study, three different commercial brands, leaders in the market, in their traditional and light versions, were subjected to sensory and instrumental evaluations. Time-intensity analyses and acceptance tests were carried out. After the statistical evaluation, applying ANOVA, the Tukey test (p. 0.05), Partial Least Square (PLS), it was concluded that the consumers preferred products with a more intense cheese flavor and higher adhesiveness, besides expressing a greater acceptance and purchase intention for the product in its traditional version.

Shotgun proteomics for the identification of yeasts responsible for pink/red discoloration in commercial dairy products

Pink/red discoloration encompasses a series of relatively common spoilage defects of commercial dairy products. In this study, we used shotgun proteomics to identify the microorganism responsible for the production of intensely red-coloured slimes found on the surface of freshly opened commercial spreadable cheese and yogurt samples. Proteome-wide characterization of microbial proteins allowed to identify 1042 and 687 gene products from Rhodotorula spp. in spreadable cheese and yogurt samples, respectively, while no significant protein scores from other microorganisms were recorded. Subsequent microbiological analyses and sequencing of the 26S rRNA gene region supported the proteomic results demonstrating that the microorganism involved was Rhodotorula mucilaginosa, a carotenoid - producing basidiomycetous that can be potentially pathogenic to humans, especially for immunocompromised individuals. This is the first time that shotgun proteomics has been used to identify a microorganism responsible for spoilage in dairy products, proposing it as a relatively fast, sensitive, and reliable alternative or complement to conventional methods for microbial identification.

Hybrid Spreadable Cheese Analogues with Faba Bean and Mealworm (Tenebrio molitor) Flours: Optimisation Using Desirability-Based Mixture Design.

Hybrid products could help bridge the gap as new alternative diets emerge in response to the demand for less animal protein, while recent studies suggest that the Western population is not yet ready to fully embrace an alternative protein-based diet. This study used a desirability-based mixture design to model hybrid spreadable cheese analogues (SCAs). The design combined milk protein concentrate (MPC), Tenebrio molitor (IF) and faba bean (FBP) flours, representing 7.1% of the formula. Nine SCAs with different MPC/FBP/IF ratios were formulated. Incorporating the IF negatively impacted the desirable texture properties. The FBP flour improved the texture (increasing firmness and stickiness and decreasing spreadability), but only when combined with MPC. Sensory analysis showed that hybrid SCAs (≤50% MPC) C2, C7 and C9 had a more characteristic cheesy flavour than the commercial plant-based reference, and sample C2 had a texture profile similar to the dairy reference. Samples containing IF (C7 and C9) showed a better flavour profile than that without IF (C2). The SCAs had higher protein and lower saturated fat, starch and sugar content than commercial analogues. The study suggests that incorporating alternative proteins in hybrid products can be an effective approach to reduce animal protein content, specifically dairy, in food formulations.
