Chinese red wine and cheese pairings: A preliminary study of consumer perception using check‐all‐that‐apply and hedonic tests

AbstractFood and wine pairing has been studied in marketing, sensory science, and hospitality fields to evaluate the gastronomic experience of consumers. In this study, three Chinese red wines (Cabernet Gernischt: CG, Marselan: MS, and Vitis amurensis Rupr: VR) were paired with two French cheeses (Brie and Camembert) and two Chinese cheeses [sweet cheese (SWC) and salty cheese (SAC)]. The physicochemical properties of wines and cheeses were determined. Also, sensory profiles of wine and cheese samples were collected using 100 participants by a check‐all‐that‐apply (CATA) test, and the ideal pairing of wines and cheeses was evaluated using hedonic, flavor intensity, and body‐to‐body relationship tests. The results showed that VR wine presented a sweet flavor and full body. MS and CG wines have a strong, bitter taste and a hot and rough mouthfeel than VR wine. The flavors of Camembert and Brie cheeses were richer and more complex than those of SWC and SAC. The textures of Camembert and Brie were elastic, smooth, creamy, fatty, and soft. VR wine enhanced consumer preference for all four types of cheeses (each combination liking score is more than six). Wine characteristics were suppressed and not enhanced by pairing with cheese. The ideal pair evaluation in terms of flavor intensity and body‐to‐body relationship confirmed that wines dominated these two aspects for cheese‐wine pairs.Practical ApplicationsCATA questions conducted with consumers are popular to profile and characterize food and beverage products. This investigation helps validate CATA method applications in food and wine pairing areas. In addition, the hedonic, flavor intensity, and body‐to‐body tests of Chinese wine and Chinese cheese pairing are helpful in promoting the development of the Chinese wine and cheese industry. The findings provide future research directions in pairing principles of food and beverages.

Valorization of wheat bread waste and cheese whey through cultivation of lactic acid bacteria for bio-preservation of bakery products

In this work, three lactic acid bacteria (LAB) strains, specifically, Lactiplantibacillus plantarum UMCC 2996, Furfurilactobacillus rossiae UMCC 3002, and Pediococcus pentosaceus UMCC 3010, were tested in new bread-whey media composed by wheat bread and sweet cheese whey, designed as an alternative to the conventional MRS medium. The medium resulting from hydrolysis with amylase and neutrase (AN) was considered the best for the growth of all the strains. This medium was particularly optimal for the strain F. rossiae UMCC 3002, which showed an increase in growth of 114% compared to that in MRS medium. Additionally, the bio-preservative ability of the selected LAB was assessed in pectin-based coated sliced bread inoculated with Aspergillus flavus ITEM 7828, Penicillium paneum ITEM 1381, and Aspergillus niger ITEM 7090. Different LAB strain behavior was observed towards the specific molds. A good bio-preservation activity was shown from F. rossiae UMCC 3002 against A. flavus ITEM 7828 with results compared to the protection by ethanol treatment. The results obtained in this study suggest a novel strategy for the cultivation of selected starters with a bio-protection activity by valorizing bread waste and cheese whey by-products, in a circular economy perspective.

Factors affecting acid protease production by Mucor circinelloides MG603064.1 through SmF process: characterization and fromage frais making.

The exploitation of food industry wastes and their conversion into value-added products present a promising and continuously growing field, given the diversity of elaborated wastes. The current work aimed to utilize sweet cheese whey as a growth medium for acid protease production by a local fungus strain. The biochemical and physicochemical properties of the cheese whey, such as pH, conductivity, chemical oxygen demand, biological oxygen demand (BOD5), total nitrogen and protein contents, and mineral salts, were assessed using various analytical methods. The effect of certain parameters on acid protease production by Mucor circinelloides MG603064.1 through the SmF process was investigated using the conventional design method "One factor at a time". Subsequent to characterization, the crude extract was used in a trial to create fromage frais, compared to the commercial rennin CHY-MAX® Powder Extra. Cheese whey characterization revealed its richness in total nitrogen (1.044 ± 0.044 g/l), protein content (6.52 ± 0.04 g/l), and principal mineral salts: calcium (1.637 ± 0.037 g/l), phosphorus (1.173 ± 0.023 g/l), and chloride (1.66 ± 0.09 g/l). The optimal values of the SmF process for acid protease production, such as the inoculum size, beef extract, and KH2PO4 supplements, the initial pH of cheese whey, and incubation temperature were, respectively, 11% (v/v), 0.4% (w/v), 0.5% (w/v), 5.5, and 30°C. Under these conditions, the lowest milk-clotting time of 290 s was achieved, representing an 18.41-fold increase compared to the initial step using the unoptimized medium. The enzyme showed maximum milk-clotting activity at pH 5, a temperature of 60°C, and in the presence of 0.025 M of CaCl2. The enzyme activity also significantly improved with sonication (35 kHz) for 10 min. The crude extract of M. circinelloides ensured the production of fresh cheese samples with characteristics roughly similar to those obtained by the control (CHY-MAX® rennin). The acid protease of M. circinelloides could successfully substitute the conventional rennin in the manufacture of fresh cheese.

Evaluation of phytotoxicity of sweet cheese whey in alfalfa and corn

The use of cheese whey in agricultural applications is an option to reduce the environmental impact caused when it is dumped without control. The purpose of this work was to measure the phytotoxicity of the sweet whey that is generated during the production of fresh cheese using seeds and seedlings of alfalfa (Medicago sativa L.) and corn (Zea mays L.) as test-object organisms. The variables evaluated were the lethal concentration (LC50) due to the inhibition of germination in both seeds, and the sublethal concentration (CSL) due to the decrease in the development of sprouts and seedlings. Four individual experiments were carried out under controlled laboratory conditions, both in Petri dishes with culture medium and in germinators with support, in a completely randomized experimental design (DECA) with five treatments (4, 8, 12, 16 and 20% of whey and a drinking water control) with a total of 252 experimental units. The results obtained indicate that sweet whey has an LC50-5 of 53% and a CSL-10 of 12% in alfalfa seeds (p<0.05) and an LC50-60 of 20% in alfalfa seedlings and an LC50-20 of 20% in corn seedlings. It was observed at 60 days that at concentrations between 4 and 6%, sweet whey has a growth-promoting effect on corn seedlings (p<0.05), concluding that it is possible to safely use diluted whey in sustainable agricultural practices.

Development of recipes for sweet processed cheese for medical and preventive purposes with “Vynograd” cryopowder

Processed cheeses have always aroused great interest and liking in a significant part of the population. They can be used for business trips, numerous picnics, and to prepare many dishes that could not be done without them. Another advantage of processed cheeses is their low cost. Therefore, in modern nutrition, processed cheeses have occupied a significant part of the food basket for a long time. The use of processed cheeses makes it possible to significantly expand not only the assortment of these products but also to improve the content of nutrients and the active, therapeutic and preventive role of food. The work aimed to develop sweet processed cheese recipes for medical and preventive purposes with cryopowder “Vynograd”. Scientific research was carried out in the conditions of the scientific laboratory of the department of technology of milk and dairy products of the Stepan Gzhytskyi National University of Veterinary Medicine and Biotechnologies Lviv and in production. The proposed technological scheme for the production of this product. The main organoleptic and technical characteristics of sweet processed cheese with cryopowder domestically produced “Vynograd” were studied. Experimental samples of processed cheese kept a delicate, elastic consistency, had a shine on the outside, and had a characteristic original taste and smell (fresh and sweet). The color of the test samples was light gray, with red-black and white inclusions of various sizes. The test samples had a crust outside and a solid ointment-like mass on the cross-section. The mass fraction of fat in the dry matter in the product was 28.0 %. The experimental cheese samples were characterized by the mass fraction of moisture – 29.8 %; sucrose – 24 %. The pH of experimental pieces of processed cheese with cryopowder was 5.6, respectively. The vitamin composition of the processed sweet cheese with Phyto-additive “Grapes” was also evaluated. Experimental samples with “Vynohrad” cryopowder are characterized by increased indicators of the biological value of the product. Testing samples of combined types of processed cheese preserved technological characteristics and regulatory safety indicators during the regulatory storage time.

Relationship between Sensory Attributes, (Dis) Liking and Volatile Organic Composition of Gorgonzola PDO Cheese.

Blue-veined cheese tends to polarize the consumers’ affective responses due to its strong flavor. This study aims to: (i) explore the consumers’ sensory perceptions and liking of Gorgonzola PDO cheese; (ii) identify the sensory drivers of acceptance for Gorgonzola in the function of the cheese style; (iii) characterize them by the volatile organic compounds (VOCs); and (iv) explore the relationships of the VOCs with sensory perception and liking. Six samples of Gorgonzola cheese differing in style (sweet vs. piquant), aging time (70–95 days), and production process (artisanal vs. industrial) were evaluated by 358 subjects (46% males, 18–77 years) using liking and Rate-All-That-Apply (RATA) tests. The cheese VOCs were measured by SPME/GC-MS. Liking was significantly higher for the sweet cheese than for the piquant cheese and for the artisanal cheese than for the industrial samples. Penalty Analysis showed that ‘creamy’, ‘sweet’, ‘nutty’, and ‘salty’ were significant drivers of liking while the ‘soapy’ and ‘ammonia’ flavors turned out to be drivers of disliking. Fifty-three VOCs were identified. Regression models revealed the significant highest associations between the VOCs and ‘ammonia’, ‘pungent’, ‘soapy’, and ‘moldy’ flavors. A good association was also found with the consumers’ liking. The identification of the sensory drivers of (dis) liking and their relationship with the VOCs of Gorgonzola opens up a new understanding of the consumers’ blue-veined cheese preferences.

Cheese whey exploitation in Brazil: a questionnaire survey

Abstract This study aimed to carry out a diagnosis of the cheese whey exploitation by the Brazilian dairy industry using a questionnaire survey. The dairy industries (n=100) were mainly from Southeast (55%) and South (25%) regions and supervised by the Federal Inspection System (80%). Most of them produced (67%) and processed (60%) sweet cheese whey, using it in whey dairy beverages (60%), Ricotta (20%), whey concentrate (15%), and milk blends (5%), which were resold for supermarkets (53%) or industries (20%). However, 27% of the industries discard whey in the effluent treatment system or use as animal feed, suggesting a market for using this by-product.

Alternative raw materials for food industry

The paper is devoted to searching for alternative raw materials for the food industry. The purpose of this study is to develop a recipe and technology to prepare cheese curds coated with dried apricots. Conventional methods are used to study structural and mechanical parameters. The results obtained when investigating structural and mechanical indicators of fruit coating for cheese curds with the software package STATISTICA 6.0 are presented. The research involves regression and correlation analysis of experimental data. Based on the results we could determine the exact amount of each ingredient in the recipe for multicomponent fruit coating of cheese curds. A recipe and the stages of manufacturing process for the production of sweet cheese curds coated with dried fruit have been developed. The manufacturing process proposed for the production of cheese curds coated with dried fruit has a number of advantages in comparison with the traditional technologies for the production of glazed cheese curds. Replacing the chocolate glaze with dried apricots resulted in decreasing the cost of the cheese curds coated with dried apricots per 5 kg batch. Moreover, cheese curds with the fruit coating are a good source of complete proteins, fiber, vitamin C, and minerals.

The aim of study is to obtain dried whey protein concentrate and to study the functional properties and physical, chemical properties. It was incorporated into pan bread made using different levels of dried whey protein concentrate. Pan bread samples were analyzed for sensory, physical and chemical attributes. The results revealed that sweet cheese whey contain 93.14% water, 4.85% lactose, 0.7% soluble protein, 0.11% fat and 0.9% ash contents. While, the produced dried whey protein concentrate contained 7.04% water 92.96% total solids, 10.47% lactose, 66.87% protein, 3.65% fat and 5.63% ash contents and contained higher levels of essential amino acids especially lysine, threonine and valine. Functional properties of dried whey protein concentrate were 4.8%, 2.2%, 50%, 80% and 0.52 g/cm3 for water absorption capacity, oil absorption capacity, foam capacity, foam stability and bulk density, respectively. Sensory, physical and chemical evaluation revealed that pan bread made using 20% dried whey protein concentrate had the best quality compared with control and other levels of dried whey protein concentrate.

Characteristics of textural and sensory properties of Oštiepok cheese

Oštiepok is a traditional half-fat semi-hard cheese made in Slovakia. The basic raw material used to produce oštiepok cheese is ewe's milk, a mixture of ewe's and cow's milk or cow's milk. Oštiepok cheese is produced either directly at a small-scale mountainside sheep farm, using the traditional on-farm method of production, or at dairies, using the industrial method. Oštiepok cheese was produced as far back as the beginning of the 18th century. An industrial production of Oštiepok cheese using cow's milk were laid by the Galbavý family in Detva (Slovakia) in 1921. The cheese is originally made by cutting off fresh sweet cheese, which is pressed into a wooden, hand-cut and decorated round shape where it is left to stand. Subsequently, it is removed and immersed in warm salty water, left to stand there until the salt penetrates completely in. Then it is necessary that it pass slightly. In its salty water, the ostrich produces its traditional durability, its surface is slightly peeled, mostly yellowish. This cheese may or may not be steamed and may be smoked or unsmoked. Slovenský oštiepok is a protected trade name under the EU's protected geographical indication. A similar cheese is made in the Polish Tatra Mountains under the name Oscypek. The cheeses differ in ingredients' ratios, cheesemaking process and the characteristics of the final products. In this study we have characterized textural and sensory properties of the Oštiepok cheese produced in Slovakia made from ewe's milk, a mixture of ewe's and cow's milk and cow's milk.

There was grounded the expedience of using cryopowder “Pumpkin” in the technology of sweet and salt cheese masses. The possibility of using cryopowder “Pumpkin” as a component of therapeutic and prophylactic cheeses masses was studied. The main factors of introduction of cryoadditive “Pumpkin” are: normative organoleptic properties of product and its daily norm. The production of cheese masses with cryoadditive “Pumpkin” provides their combination with sugar or salt. The use of cryoadditive “Pumpkin” needs preliminary comminution and mixing them with sugar-sand or salt. The receipts of 4 types of cheese masses with cryoadditive “Pumpkin” (two fatless and two semi-fat ones) were elaborated. At introduction of cryoadditive “Pumpkin” in cheese masses their food value increased. The organoleptic, technological and commodity characteristics of these cheese masses were studied. It was established, that the color of sweet cheese masses was cream with separate yellow dots of comminuted powder-like cryoadditive and the color of salt cheese masses was, correspondingly, yellow. In sweet cheese masses the distinct smell of cryoadditive was perceptible, whereas in salt cheese masses it was fresh, sour-milk. The flavor of studied samples was more expressed in sweet cheese masses. The offered cheese masses had pleasant, original commodity look, normative physical-chemical characteristics. The titrated acidity of studied samples of salt cheese masses was 124–130 °Т, moisture ms - 62–60 % and dry substances – 40–38 %, and titrated acidity of studied samples of sweet cheese masses was126–134 °Т, moisture ms 63–66 % and dry substances – 34–37 %. The offered production widens the assortment of milk products of therapeutic and prophylactic direction.

Whey cheese: membrane technology to increase yields.

Sweet cheese whey has been used to obtain whey cheese without the addition of milk. Pre-treated whey was concentrated by nanofiltration (NF) at different concentration ratios (2, 2.5 and 2.8) or by reverse osmosis (RO) (2-3 times). After the concentration, whey was acidified with lactic acid until a final pH of 4.6-4.8, and heated to temperatures between 85 and 90 °C. The coagulated fraction (supernatant) was collected and freely drained over 4 h. The cheese-whey yield and protein, fat, lactose and ash recoveries in the final product were calculated. The membrane pre-concentration step caused an increase in the whey-cheese yield. The final composition of products was compared with traditional cheese-whey manufacture products (without membrane concentration). Final cheese yields found were to be between 5 and 19.6%, which are higher than those achieved using the traditional 'Requesón' process.

Inhibition of bacterial growth in sweet cheese whey by carbon dioxide as determined by culture-independent community profiling

Whey is a valuable co-product from cheese making that serves as a raw material for a wide range of products. Its rich nutritional content lends itself to rapid spoilage, thus it typically needs to be pasteurised and refrigerated promptly. Despite the extensive literature on milk spoilage bacteria, little is known about the spoilage bacteria of whey. The utility of carbon dioxide (CO2) to extend the shelf-life of raw milk and cottage cheese has been well established, but its application in whey preservation has not yet been explored. This study aims to characterise the microbial populations of fresh and spoiled sweet whey by culture-independent community profiling using 454 pyrosequencing of 16S rRNA gene amplicons and to determine whether carbonation is effective in inhibiting bacterial growth in sweet whey. The microbiota of raw Cheddar and Mozzarella whey was dominated by cheese starter bacteria. After pasteurisation, two out of the three samples studied became dominated by diverse environmental bacteria from various phyla, with Proteobacteria being the most dominant. Diverse microbial profiles were maintained until spoilage occurred, when the entire population was dominated by just one or two genera. Whey spoilage bacteria were found to be similar to those of milk. Pasteurised Cheddar and Mozzarella whey was spoiled by Bacillus sp. or Pseudomonas sp., and raw Mozzarella whey was spoiled by Pseudomonas sp., Serratia sp., and other members of the Enterobacteriaceae family. CO2 was effective in inhibiting bacterial growth of pasteurised Cheddar and Mozzarella whey stored at 15°C and raw Mozzarella whey stored at 4°C. The spoilage bacteria of the carbonated samples were similar to those of the non-carbonated controls.

Cheese whey treated by membrane separation as a valuable ingredient for barley sourdough preparation

Utilisation of cheese whey for production of healthier food has been the main task of this study. Cheese whey, which is often considered as a waste material, was treated by a series of processes including fermentation, membrane filtrations, mixing with barley flour, drying, and/or extrusion to produce barley sourdough.In the first series of experiments, the effect of membrane ultrafiltration (UF) and nanofiltration (NF) on separation of whey components has been studied. Non-fermented sweet cheese whey was treated by pilot-plant membrane ultrafiltration (50kDa tubular ceramic membrane, TAMI Industries, France), followed by three step diafiltration to minimise losses of lactose, glucose, galactose, and organic acids (namely lactic acid) in retentate. The UF permeates were used for the subsequent nanofiltration and diafiltrations (spiral wound membrane NF 270-2540, Filmtec, Dow Chemicals, USA). The results showed high recovery of proteins (81%) during UF and reduction of lactose and propionate losses by using diafiltration. Rejections of components on the NF membrane were: 93% lactose, 77% galactose, and 76% lactic acid. However, the diafiltration on the NF membrane reduced the relative recovery both for carbohydrates and organic acids.In the second series of experiments, cheese whey was concentrated by reverse osmosis (RO) and the obtained retentate was fermented with Lactobacillus plantarum, Lactobacillus sanfranciscensis and Propionibacterium freudenreichii subsp. freudenreichii. Part of the fermented whey was mixed with barley flour and dried by cold air fluid drying to produce sourdough pellets. The other part of fermented whey was filtered by nanofiltration and both permeate and retentate were sprayed on the surface of sourdough pellets in several layers and dried again. The extrusion of a mixture containing barley flour and fermented whey was tested for pellet production as well. The main aims were to obtain sourdough rich in natural preservatives, and maintain the present microorganisms active. That is why all the technological processes, including drying, were carried out under low temperatures. The content of organic acids (lactic, acetic and propionic) was analysed in final sourdough samples.

Relating the effects of protein type and content in increased-protein cheese pies to consumers' perception of satiating capacity.

Since proteins have been shown to have the highest satiation-inducing effects of all the macronutrients, increasing the protein level is one of the main strategies for designing foods with enhanced satiating capacity. However, few studies analyze the effect that protein addition has on the texture and flavor characteristics of the target food item to relate it to the expected satiating capacity it elicits. The present work studied cheese pies with three levels of soy and whey proteins. Since the protein level altered the rheological behavior of the batters before baking and the texture of the baked pies, the feasibility of adding several protein levels for obtaining a range of final products was investigated. A check-all-that-apply questionnaire containing 32 sensory and non-sensory characteristics of the samples was given to consumers (n = 131) who also scored the perceived samples' satiating capacity. The results showed that the type and content of protein contributed distinctive sensory characteristics to the samples that could be related to their satiating capacity perception. Harder and drier samples (high protein levels) were perceived as more satiating with less perceptible sweet and milky cheese pie characteristic flavors. Soy contributed an off-flavour. These results will contribute to a better understanding of the interrelation of all these factors, aiding the development of highly palatable solid foods with enhanced satiating capacities.

Addendum to Issue 1 - ENZITEC 2012 Cheese whey and passion fruit rind flour as substrates for protease production by Bacillus sp. SMIA-2 strain isolated from Brazilian soil

Application of wastes from the food processing industry as carbon sources in enzyme production processes reduces the cost of production, and also helps in solving problems of their disposal. In this work, we demonstrated that sweet cheese whey, in combination with passion fruit rind flour, can be successfully used for the production of protease by Bacillus sp. SMIA-2, opening perspectives for the use of these agricultural byproducts as novel and cost-effective culture media for the production of protease. The maximum production of the enzyme was observed in a sweet cheese whey-based culture medium preparation (0.5%, w/v) containing 0.25% (w/v) passion fruit rind flour and supplemented with different metal salts at an initial pH of 7.5–8.0, incubated at 50°C for 48 h. Studies on enzymatic characterization revealed that crude protease showed maximum activity at pH 9.0 and 70°C. These characteristics presented by the protease produced by Bacillus sp. SMIA-2 could be very useful when thinking about biotechnological applications.

Identifying cheese whey an adulterant in milk: Limited contribution of a sensometric approach

A sensometric approach for the identification of sensory descriptors that characterize milk samples added with whey was investigated. Sweet cheese whey (pH=6.59, nonfat dry=8.06% w/w) was added to raw milk in increasing concentrations (0, 5, 10, 15 and 20% v/v), and then submitted to quantitative descriptive analysis. The data treated used multivariate statistical methods, principal component analysis (PCA) and hierarchical cluster analysis (HCA). Some inconsistent results were reported during the evaluation of the samples, suggesting problems along the panel member training and/or lack of concentration, motivation along the test. Our results suggest chemometric methods allied to descriptive sensory tests present limited contribution to investigate authenticity of milk due the presence of cheese whey. This aspect compromising the performance the multivariate analysis, which findings should be face as tendency.
