If we are to list, some of the well known product frequently used in almost all household are Curd, Youghurt, lassi, chach, paneer, dairy sweets etc. Requirement of these processing evolved from the fact, that milk is highly perishable in nature and cannot be stored long, hnec processing if milk help in achieving the product shelf life from certain days to months. bulgaricus Lactobacillus Yoghurt, it is feremented dairy product having sort of thick consistency. And as per FDA code of Federal Regulations – “yogurt is a food produced by culturing cream, milk, partially skimmed milk, or skim milk alone or in combination with a bacterial lactic acid–producing culture that contains the bacteria and Streptococcus thermophilus.” Being a rich source of protein and calcium, the fermentation process facilitate the absorption of nutrients in our body. The live bacteria in yoghurt promotes the balancing of good and required microflora in stomach hence promoting digestion. Apart and Streptococcus thermophilus other bacterial culture such as Lactobacillus acidophilus, Lactobacillus subsp. Casei, and Bifido-bacteria as probiotic culture. Lactobacillus bulgaricus from into The bacterial fermentation of milk facilitates the yoghurt manufacturing process. The process starts with bacteria fermenting the present milk sugar of milk lacit acid lactic acids. The produced brings down the milk pH to range of 4 and this causes the beginning of protein coagulatation in milk. The influential parameters for yoghurt thickness, consistency, texture and taste are -Starter culture -Fat content of milk -Amount if milk solid, protein set Another approach consistency product to add skimmed milk powder- the catch point being, addition of skim milk powder to cold milk rather than heated milk or instead of firmer yoghurt, stringy natured yoghurt will be observed. to have is thick and Yoghurt and its type Natural Yoghurt – When no flavour or sweetener are added to the prepared yoghurt Flavoured- Have added flavour and sweeter that can be natural or artificial sweeteners Greek Yoghurt – Natural yoghurt goes through straining process to remove whey content.

Set Yoghurt- Yohurt when fermented in final packing material to get set form. Stirred Yoghurt- After incubation period is over and yoghurt proceeds for filling it is stirred at particular RPM for certain time to cut have stirred yoghurt Drinking Yoghurt- To fluidity and flavour, milk is added along with desired fruit and fruit syrups. Frozen Yoghurt- Regular yoghurt is mixed with pasteurized ice cream mix of milk cream and sugar along with other ingredients such as stabilizers and then frozen Yohurt Cheese – Also known as “Labna” , which has its whey drained increase the How is Yoghurt Processed ? Yoghurt process or commercial manufacturing have following steps involved - Step-1: Milk Composition There is desirable characteristic that is required to start with yoghurt processing. As mentioned, the texture and end consistency depend upon milk composition and to be specific – milk solids. To increase the protein content, skim milk powder is also added in cold milk which enhances the texture. is Step-2: Pasteurization The pasteurization step to kill pathogenic microorganism from milk so that the processed product is free of any form of contamination. The process can be either batch pasteurization or continuous pasteurization depending upon the facility. Pasteurization is done at temperature range of 90-95 Deg C with holding time of 10 minutes. Step-3: Homogenization Along with pasteurization, the milk is homogenized where the fat globules are uniformly broken in to smaller consistent product. Step-4: Cooling Milk is cooled down to temperature of 42+2 Deg C, which growth temperature to bacteria. to provide most suitable is Step-5: Fermentation Milk is inoculated with the fermentation culture to a concentration range of 1.5-2% and the temperature of milk is maintained at 42+2 Deg C for 4-6 hours, depending upon the time required to attain the lower pH of 4 flavors/fruits and other Step-6: Addition of ingredients Flavors are added to product after cooling. Reducing the temperature stops the fermentation process, hence reduces the change or acidity change. Flavour addition is also dependent on the type of final product required- In case of set curd, fruits are added at the bottom of the packing cup and then filled with product, while it can also be belended with product during/after fermentation process and then cooled for packing. Yoghurt with abundant nutritive value is currently under extensive studies, to unveil many other health benefits of taking yoghurt in diet apart form already known benefits such as acting as immunity booster, reducing chances of infection and reducing risk of colon cancers. To make it more attractive and to satiate the demand of consumers, research works are going on for new flavour developments, along with increasing nutritional content an decreasing the shelf life of yogurt.

Undeniably paneer is a versatile delight which happens to be the most loved main course, side dish and appetizer delicacy. No matter how you prepare paneer, its amazing taste can add soul to any party or occasion. Popularly consumed in South Asian subcontinents, especially in India; From appetizer to desserts, paneer can certainly food experience up by a notch. take your Interestingly, every year about 5% of milk is converted to paneer. Indian paneer is the fresh and non-melting cheese, which is prepared by curdling of milk using some citric acid or any acidic vegetable liquid. The curdled milk is also called as chena or cottage cheese. The only minor difference between Indian paneer and regular cottage traditional cheese is that cottage cheese contains a little salt. is obtained by Paneer the acid and heat coagulation of milk at a high temperature. Paneer contains large structural aggregates of proteins formed during the coagulation of milk in which milk fat and other colloidal and soluble milk solids are entrained with whey. According to FSSR, paneer shall not contain more than 70% moisture and the fat content should not be less than 50% of dry matter. Good quality paneer is characterized by a white color, sweet, mildly acidic flavor, spongy body, and a closely knit texture. Paneer has a high nutritional profile as it retains about 90% of the fat and protein, 50% of the minerals, and 10% of the lactose of the original milk. The proximate composition of paneer is 54% moisture, 17.5% proteins, 25% fat, 2% lactose, and 1.5% minerals. Manufacturing of Paneer Commercial production of paneer involves 6 process steps-: Step 1: Milk Standardization For commercial manufacture of paneer buffalo milk is standardized to 5.8% fat having 9.5% SNF (standardize the buffalo milk to a fat: SNF ratio of 1:1.65). Step 2: Heat Treatment: After standardization of milk, it is heated to 90°C without holding (or 82°C with 5 minutes holding) in a jacketed closed vessel known as Paneer Vat. Then is allowed to cool down to 70°C. Heat milk treatment of causes microorganisms, denatures whey proteins and retards colloidal calcium phosphate solubility. destruction of milk PMG DESIGN+BUILD FOOD FACTORIES.

Vol .03-Issue .03-January 2024 Step 3: Coagulation and Draining of Whey Coagulation is done at about 70°C by slowly pouring 1% hot (70°C) citric acid solution with constant stirring till a clean whey is separated (pH 5.30 to 5.35) and coagulum is allowed to settle for 5 minutes, after which the whey is drained off. Step 4: Hooping The curd so obtained is filled into hoops lined with cloth. Step 5: Pressing Pressure is applied on top of the hoop at a rate of 0.5 to 1kg/cm2. The surface of hoops must contain holes to facilitate whey expulsion. Good quality product can be prepared by pressing for around 15 min. Step 6: Dipping in Chilled Water The pressed blocks of paneer are removed from the hoops and immersed in chilled water for 2-3 hrs. The chilled paneer is then removed from water to drain out. This step assists in developing texture and speeds up the cooling process. The water used for chilling should be of good bacteriological quality. Step 7: Packing Finally, paneer blocks are wrapped in parchment paper / polyethylene bags and placed in cold room at about 5 to 10°C. Quality Affecting Factors Type of milk Paneer prepared from buffalo milk will have desirable frying properties, body and texture as compared to cow milk. The cow milk paneer is too soft, weak, and fragile and during cooking it tend to disintegrate. Paneer made from skim milk has chewy, rubbery, and hard body. Quality of Milk To obtain paneer of good quality, the milk must be fresh and free from off flavor. Growth of psychotropic organisms should be minimized to restrict the off- flavor development. The milk with COB positive and low acidity is not suitable for paneer making. Paneer made from such milk has weak body and texture, more moisture, acidic smell and not safe for human consumption. Type and Strength of Coagulant Citric acid is generally used as a coagulant. The concentration of citric acid used for best results is 1%. A higher concentration may lead to a harder product with a higher loss of solids. For coagulating 1 kg of milk, about 2–2.5 g of food-grade citric acid is used. Heat Treatment of Milk The milk is heated to 90°C without holding or 82°C for 5 minutes to maximize the total solids recovery. Whey proteins especially ß-lactoglobulin and a-lactalbumin form a complex with Қ-casein and retain with the curd thus increase the yield of the product. The high heat treatment flavor by imparts desirable controlled liberation of sulfhydryl compounds. cooked Coagulation Temperature At 70° C, paneer has the best organoleptic and frying quality in terms of shape retention, softness, and integrity. pH of Coagulation The optimum pH of coagulation of milk at 70°C is 5.30-5.35. The moisture retention in paneer decreases with the fall in pH and consequently the yield also decreases. Optimum pH when cow milk is used for paneer preparation is 5.2. in Due to increasing demand for paneer, advancement is required in the manufacturing of paneer which will result in production cost, and increase in shelf life of paneer as well as production of new varieties of paneer for health-conscious people. increased yield of paneer, reduction PMG DESIGN+BUILD FOOD FACTORIES.
