PurposeMilk cake is a well-renowned khoa-based dairy product in India, produced either from the buffalo milk or using a specific danedar variety of khoa. Under ambient conditions, shelf-life of milk cake is generally up to 3–4 days, whereas under refrigeration conditions, it can last up to 12–14 days. Therefore, the present study aims to evaluate the effect of modified atmosphere packaging (MAP) to enhance the shelf-life and keeping intact freshness of milk cake under refrigerated conditions (4 ± 2 °C).Design/methodology/approachDifferent gas concentrations of N2 and CO2 (70:30, 50:50 and 90:10) were used as a treatment, whereas control samples were kept under atmospheric air composition. The product was examined for sensory, physicochemical and microbiological parameters at weekly intervals.FindingsThe physicochemical and microbiological attributes displayed gradual elevation with progressive storage period in all the samples. However, the overall sensory profile of the product remained acceptable for a longer duration. Most of the quality parameters in control declined more rapidly with a shelf life of 14 days, in comparison to MAP packed samples, where gas flushing with the ratio 70:30 was found to be best suited for extending the shelf life of milk cake up to 28 days at refrigeration temperature.Originality/valueTo extend the shelf life of milk cake, modified atmosphere was provided with different gas ratios to reach a best-suited environment for sensory, storage life and proximate parameters.

AbstractMeekiri (sometimes also known as Mee-Deekiri); fermented buffalo milk gel is a deep-rooted dairy product in Sri Lankan food culture and the production of Meekiri plays an integral part in the livelihood of rural farming. Meekiri consumption is widespread irrespective of geographic boundaries, across the cultural and/or ethnic communities. In Sri Lanka, buffalo milk is predominantly used in producing Meekiri, where production has been specialized in various geographic areas in the country, associated with major buffalo farming regions. Physicochemical and microbiological quality attributes are apparent to differ in Meekiri according to varying production regions, processing techniques and storage conditions. The mouthfeel and taste of Meekiri are widely accepted to be thicker and creamier with a pleasant note and is whiter in colour compared to fermented cow milk gel/yoghurt. Since Meekiri production is localized in Sri Lanka and available as traditional know-how at the primary production level, up-to-date comprehensive scientific literature that accounts for processing and detailed product quality characteristics is lacking. Hence, this review evaluates and outlines updated information about the Meekiri production, associated buffalo farming systems, quality characteristics of Meekiri including physicochemical, sensorial and microbiological aspects in the final product.

Packaging of dairy products develops continuously along with advances in material technologies, which are in turn a response to demands of consumers. This article aimed to give an overview of currently available dairy packaging systems. Novel dairy packaging systems include new packaging technologies such as the modified atmosphere packaging (MAP) that is widely used nowadays, especially for dairy product like cheese. Application of edible packaging could significantly reduce the costs of cheese packaging by reducing the amount of usually required packaging material. Nanomaterials and active packaging might be useful for extending the shelf life of dairy products by reducing material permeability or negative sensory characteristics of batch processing. Forms of active packaging relevant to dairy foods include oxygen scavenging, carbon dioxide absorbers, moisture and/or flavour/odour taints absorbers; releasing compounds (carbon dioxide, ethanol, antioxidants and/or other preservatives); maintaining temperature control and/or compensating temperature changes and antimicrobial packaging. Antimicrobial packaging is gaining interest from packaging scientists and industry due to its potential for providing quality and their safety benefits. The greatest challenge from the ecological point of view is biodegradable packaging. The main challenges for low waste materials are the durability of the packaging correlated with product shelf life as well as the ecological perspective.

Cheese is a dairy product with potential health benefits. Cheese consumption has increased due to the significant diversity of varieties, versatility of product presentation, and changes in consumers’ lifestyles. Spoilage of hard and semi-hard cheeses can be promoted by their maturation period and/or by their long shelf-life. Therefore, preservation studies play a fundamental role in maintaining and/or increasing their shelf-life, and are of significant importance for the dairy sector. The aim of this review is to discuss the most effective methods to ensure the safety and sensory quality of ripened cheeses. We review traditional methods, such as freezing, and modern and innovative technologies, such as high hydrostatic pressures, chemical and natural vegetable origin preservatives, vacuum and modified atmosphere packaging, edible coatings and films, and other technologies applied at the end of storage and marketing stages, including light pulses and irradiation. For each technology, the main advantages and limitations for industrial application in the dairy sector are discussed. Each type of cheese requires a specific preservation treatment and optimal application conditions to ensure cheese quality and safety during storage. The environmental impact of the preservation technologies and their contribution to the sustainability of the food chain are discussed.

<p>Dadih is a traditional dairy product obtained from a fermentation of buffalo milk and usually packed using bamboo. The usage of bamboo for dadih packaging has limitation in transportation and storage life. This study aimed to examine the effect of packaging material to dadih quality produced from cow milk during storage. Experimental design used at this study was Completely Randomized Design with Factorial pattern (7 x 7). The first factor is packaging material that are bamboo; cup plastic pp; flexypack packaging; clay; flexypack packaging (with evacuation from bamboo); clay (with evacuation from bamboo); cup plastic pp (with evacuation from bamboo). The second factor is storage time (0, 4, 8, 12, 16, 20, and 24 days). Result showed that best packaging to cow milk dadih is flexypack and cup plastic pp. Cow milk dadih that was packed in flexypack and cup plastic pp had storage life up to 24 days at cold temperature (refrigerator). From the perspective of economic, cup plastic pp packaging showed most efficient<br />packaging. Characteristic of cow milk dadih packaged in cup plastic pp were total of titratable acid 1,60%; pH 3,88; viscocity 351,43 cPs; total solid 14,75%; water content 85,25%; ash content 0,90%; protein content 2,43%; fat content<br />3,68%; total of lactic acid bacteria (LAB) at 8 x 1011 CFUs/g.

Psychrotrophic microorganisms, especially Pseudomonas spp., are present in the microbiota of refrigerated milk as they can grow at refrigeration temperatures irrespective of their optimal growth temperature. Psychrotrophic counts ranging from 105 to 108 CFU/mL in refrigerated raw milk effect cheese quality, since the synthesized thermoresistant enzymes affect the nutritional value, sensory properties, and texture. Cheese is the dairy product with the highest growth rate in the food industry in Brazil in recent years and meets the current consumption trends of nutritious and practical foods. The objective of this review was to address the importance and influence of the psychrotrophic raw milk microbiota on the quality and sensory properties of cheese. The enzymes produced by psychrotrophic microorganisms lead to taste changes, undesirable clotting times, increased concentrations of free fatty acids and free amino acids, and a reduced shelf-life, in addition to negatively affecting cheese yields. Proteases from psychrotrophs are also associated with slicing problems and progressive loss of the elasticity of cheese, a bitter taste, and increased clotting times of cheese produced with pasteurized milk. On the other hand, their lipases increase the clotting time and have a negative effect on the sensory properties by providing a rancid, soap, metallic, or oxidized smell and taste. The control of the psychrotrophic population found in refrigerated raw milk contributes to better cheese production yields and desirable texture and sensory properties, which extends the shelf-life of cheese and improves consumer acceptance.

The objective of this study was to know the existing buffalo milk trade and dairy products production status along with scope for buffalo milk product branding. Hence, a face-to-face interview with eighteen milk traders and processors were performed through simple random sampling method. Milk traders and processors were above 25 years old (94%) and above 5 years (89%) experienced in dairy business. The findings exposed that 11% of the participants were involved in milk collection and selling, 39% were directly involved in product manufacturing, and 50% were engaged in milk collection and processing. Among the manufactured dairy products, traditionally made fermented doi was the best - selling dairy product in the Bhola district. About 47% participants desired to incorporate fat-rich dairy products into their production processes. In general, milk traders sold the maximum amount of milk monthly to doi manufacturers (1453 L), followed by local customers (1175 L), sweetmeat manufacturers (1000 L), restaurants (257 L), and household consumers (250 L). Results showed that buffalo milk prices varied significantly (P<0.001) over the year. The peak buffalo milk price (122 BDT/L) was recorded between November and December, and the off-peak price (82 BDT/L) was between March to May. Data indicated that about 43-50 BDT profit derived through per kg doi and sweetmeat selling. Milk traders and processors mentioned that studied areas had greater shortage of milk preservation facilities. Overall, the findings of this study may give some context for developing sustainable buffalo milk and dairy products value chain in Bangladesh. Res. Agric., Livest.

The aim of this study was to evaluate fig (Ficus carica L.) leaves’ extract (FLE), olive (Olea europaea L.) leaves’ extract (OLE), and their mixture (MLE), to extend the shelf life of pasteurized milk. OLE, FLE, and their mixture MLE (1:1) were added to the pasteurized milk in different concentrations (0.2%, 0.4%, and 0.6%). Several tests were then conducted to determine the activity of these extracts. The antioxidant activity as IC50 was determined by using DPPH radical assay. FLE showed higher IC50 (30.21 µg/mL) compared to the IC50 of OLE (22.43 µg/mL). Phenolic compounds were identified by using high-performance liquid chromatography (HPLC). The highest antimicrobial activity was obtained with 0.6% concentration. Organoleptic properties indicated that the addition of these extracts did not affect the sensory properties of pasteurized milk. Pasteurized milk treated with 0.6% of FLE, OLE, and MLE has significantly decreased (p ≤ 0.05) lipase and protease activity during the storage period, at 5 °C. The results indicated that extending the shelf life of pasteurized milk from 5 to 16 days was successfully achieved through using 0.6% of FLE, OLE, and MLE. The combination of the two extracts (MLE) provides an efficient and safe method to prolong the shelf life of pasteurized milk, without altering the properties of pasteurized buffalo milk.

AbstractAdults aged > 50 years, which make up to 40% of the European population, are vulnerable to low vitamin B12 (B12) status due to age-related factors that impair digestion and absorption of protein-bound B12 from natural food sources. Older adults are recommended to meeting their dietary B12 intake through the consumption of B12-fortified foods or supplements because these products contain free B12. B12 seems most bioavailable from milk products compared to other food sources, showcasing dairy as a potential vehicle for B12 food fortification. Yogurt is a versatile, popular dairy product, making it a promising food vehicle for B12 fortification to enhance the availability of B12-fortified foods for population groups at risk of B12 deficiency. With the overall goal to develop a novel, B12-fortified dairy product, the objective of this project was to compare the shelf-life stability of different chemical forms of B12 added to yogurt either in isolated or in encapsulated form. For both fortification strategies, we compared methylcobalamin (MeCB), a naturally-occurring B12 form, and cyanocobalamin (CnCB), the synthetic form of B12. Encapsulated microparticles were created by spray-drying a maize starch-derived polymeric material (EUDRAGUARD Natural®) with 1% (w/V) MeCB or CnCB. The release of B12 from encapsulated microparticles was confirmed by in vitro simulated gastrointestinal digestion; maximum B12 release (103% recovery) was achieved under conditions simulating the small intestine, where B12 is absorbed in the human body. Yogurts were produced by incubating whole milk (3.25% milk fat) with yogurt starter bacteria at 43°C overnight; after fermentation and cooling down, isolated (I-MeCB or I-CnCB) or encapsulated B12 powders (E-MeCB or E-CnCB) in the concentration of 50μg of B12/175 g of yogurt were added, creating stirred yogurt. Yogurts were stored at 4°C for eight weeks, with intermittent sampling for B12 stability testing using RIDASCREEN immunoassay. For CnCB-fortified yogurts, I-CnCB and E-CnCB had similar B12 concentrations at baseline (48.3μg and 48.2μg, respectively) and week 8 (53.9μg and 51.4μg, respectively). Difference in B12 content between I-CnCB and E-CnCB was < 5% for both time-points. For MeCB, similar concentrations were found for I-MeCB (64.1μg) and E-MeCB (65.0μg) at baseline; however, at week 8, E-MeCB remained stable (69.8μg) while a pronounced decrease in B12 was observed with I-MeCB (33.3μg). At week 8, I-MeCB B12 concentrations were 52% lower than E-MeCB. In conclusion, CnCB was shown to be the more stable fortificant throughout shelf-life. Encapsulation techniques are a viable option to increase MeCB stability in fortified yogurts.
