Specification

FIELD OF THE DISCLOSURE:
The present disclosure relates to a coating formulation meant for coating of paneer and a process for preparing the same. The present disclosure also relates to a coated paneer and a process for preparing the same.
BACKGROUND:
Paneer is one of the traditional dairy products of India which is analogous to the western cottage cheese. It is mainly produced by local dairies or milk product distributors or cottage scale industries. Milk production in India for the year 2009-2010 was 112.5 million tones. It is estimated that about 35 per cent of the total milk produced in India is processed.
Paneer act as the base or filler for several popular Indian delicacies such as shahi paneer, matar paneer, karahi paneer, paneer samosa, paneer bhurji, paneer paratha, paneer methi paratha and many such culinary dishes and recipes. However, paneer is mostly stored and marketed unpacked which leads to the irreversible and undesirable changes in paneer. Non-packaging affects the microbiological quality, sensory attributes, moisture, acidity and texture of paneer. Improper packaging leads to increase in acidity and moisture loss. Usually, shelf life of unpacked or improperly packed paneer under refrigeration (5°C) is six days and at room temperature (30°C) is one day. Further, the freshness of paneer is lost within three days when stored under refrigeration (5°C). It is observed that the short shelf life of paneer is mainly due to surface spoilage. The surface
spoilage of paneer is mainly caused by the growth and development of bacterial slimy layer on the surface which result in increase in acidity of paneer. This makes the product unacceptable in the market.
European Patent No. 0593123 discloses an edible coating composition comprising thickeners, plasticizers, acids, proteins, hydrophobic substances and combinations thereof. The coating composition is prepared by a process which involves preparation of a suspension of an edible coating composition, spreading the obtained suspension on support and removing the water from the suspension to obtain a continuous film.
WO 98/42214 discloses an edible composite films and coatings for use as a moisture barrier in multi component food stuff so that the different textural and organoleptic qualities of various food components can be maintained. An edible composite film and coating mainly comprises lipid and hydrocolloid components. Lipid component is derived from dried fat composition and hydrocolloid component comprises starchy leguminous seed protein or lupin protein.
European Patent No. 0946105 discloses a process for coating a food product which comprises applying directly to the food product at least one layer of an edible hydrophobic composition and at least one layer of an edible hydrophilic composition.
The process disclosed in EP 0946105 involves coating of two layers i.e. hydrophobic layer comprising fat and hydrophilic layer comprising protein. Further, the coating layer also comprises emulsifying agent. This altogether makes the process complicated and expensive.
European Patent No. 1202634 discloses a coating composition for cheese which comprises esterified product of at least one fatty acid; and at least one branched polyol having at least three carbon atoms and at least two hydroxy 1 groups.
The coating composition disclosed in European Patent No. 1202634 is non-edible in nature. The constituents of coating may migrate to the food product, making it unhealthy and unsafe for consumption.
Another, European Patent No. 1537786 discloses a composition for coating food and food ingredients. The composition comprises a copolymer comprising vinylic ester of a saturated hydrocarbon, at least one of a maleic or fumaric ester and a stabilizing monomer, a protective colloid and a non-ionic emulsifier.
Indian Patent No. 224108 discloses a process for manufacturing of paneer having moisture content in the range of 15 % to 40%. The process involves following steps-
i. soaking of paneer in a solution of humectants in the ratio of 1:1.3; wherein the solution of humectants comprises glycerol and NaCl; ii. adding chemical preservative to the solution of humectants and subsequently adjusting the pH to 5.0 to 5.5; iii. immersing paneer in the solution of humectants for 15 hours to 30 hours at refrigerated temperature for equilibrating; and iv. dehydrating till the moisture content is 15 % to 40%.
The drawback associated with the process of Indian Patent No. 224108 is that the produced paneer is rubbery in nature because of dehydration and therefore it needs to be rehydrated before consumption.

Further, the process of rehydration may make paneer tasteless.
Further, the use of various antimicrobial agents such as benzoic acid, brine solution, BHA or TBHQ to increase the shelf life of the food product has been reported by various researchers.
Various coating composition for preservation of food products such as cheese are known in the art, however, these coating compositions are not effective to avoid the formation of microbial slimy layer, wheying-off during storage, distribution and marketing, changes in sensory quality i.e. development of acidic flavor, changes in textural quality i.e. crumbliness/brittleness and fragility due to moisture loss during storage. Accordingly it is desirable to develop an edible coating formulation which can provide effective moisture barrier and antimicrobial properties.
OBJECTS OF THE DISCLOSURE:
It is an object of the present disclosure to provide a simple process for preparing paneer. It is another object of the present disclosure to provide an edible coating formulation which is useful for coating various food products.
It is still another object of the present disclosure to provide a simple and economic process for preparing an edible coating formulation.
It is yet another object of the present disclosure to provide a coated paneer which has improved moisture barrier and antimicrobial properties.
It is a further object of the present disclosure to provide a simple and economic process for the preparation of coated paneer.
