A study was undertaken to develop an ‘instant chicken soup mix’ incorporated with spent hen meat shred and to evaluate its cost of production. Four treatment soup mix combinations containing 0%, 20%, 25% and 30% meat shred were prepared and cost of production was evaluated. Cost of formulation was found to be highest for Treatment D followed by C, B and A. Net profit was found to be highest for Treatment D followed by C, B and A. Estimating the details of economics of the developed products, it can be concluded that a viable enterprise can be established by keeping the cost per kg as Rs. 273, Rs. 455, Rs. 500 and Rs. 546 for Treatment A, B, C and D respectively.
Soup is probably one of the oldest foods of human being, since it must have developed about the time when boiling was established as very fast form of cookery. Chicken soup is simple to prepare, relatively cheap, nutritious, easily digestible and highly cherished by young generation. For instance, it is regarded as the most ubiquitous medicinal soup in the world. Chicken soup might have anti-inflammatory activity, namely, the inhibition of neutrophil migration (Barbara et al., 2000) and could hypothetically lead to temporary ease from symptoms of illness (Rennard et al., 2000). Normally soups are consumed before meals to stimulate the appetite and flow of digestive juices in stomach. Chicken soup is often referred as “Jewish penicillin”, “bohbymycetin” and “bobamycin” (Caroline and Schwartz, 1975; Saketkhoo et al., 1978).
Convenience food sector is one of the largest growing segments of food industry throughout the world. Dry soup mixes are well recognized convenience food item in the world food markets. Instant soup mixes are preferred by consumers because of their convenience in preparation, shelf stability and excellent appetizing property. Soup market in India was reported to be in the range of INR 100-125 crores in 2010 (Juse, 2012). The category of ready-to-cook soup mixes formed 25 percent of the instant food segments (Juse, 2012). The major brands in ready to cook soup mixes in Indian market are Knorr (Hindustan Uniliver), Maggi (Nestle), Ching’s secret (Capital Foods), Bambino (Bambino Agro), Sil (Scandin Food), Campbell’s (Weikfield Products) etc. Apart from good storage stability, nutritional and therapeutic properties, the increasing health consciousness amongst the population has led to increased popularity of instant soup mix all over the world.
The layer bird population of India was around 247 million in 2010 (Juse, 2012). Effective utilization of layer birds after the end of their productive life is one of the urgent requirements of the poultry industry as 30 percent of the poultry slaughtered are spent hens (Juse, 2012). Spent hen meat is a by-product of egg industry obtained from old and culled chicken, after productive and reproductive phase of life; which has high fat and cholesterol content, low tenderness, less juiciness and poor functional characteristics resulting in low acceptability and lower remunerative prices as compared to broiler meat (Saini, 2016). However its nutritional quality is similar to broiler meat (Chueachuaychoo et al., 2011). Improved deboning techniques and modern methods of meat processing could enhance the quality and value of meat from spent hens leading to greater demands and better financial returns (Kondaiah and Panda, 1992). Since spent layers are very cheap source of meat it can be used successfully in the formulation of many value added meat products (Kim and Ahn 1997). Thus, the present study was undertaken to develop and evaluate cost of production of instant soup mix incorporated with spent hen meat shred.
Materials and Methods
Spent hens of commercial layer birds were obtained from Regional Poultry Breeding Farm, Kyrdemkulai, Ri Bhoi District, Meghalaya, India. Following ante-mortem examination, spent hens were slaughtered under humane and hygienic conditions, in the Department of Livestock Products Technology, College of Veterinary Science, Khanapara, Guwahati. The dressed carcasses were deboned manually following proper hygienic conditions. All visible fat, fascia and connective tissue were separated and trimmed off and the meat was minced through 6 mm plate in a meat mincer and packed in low density polyethylene (150µm thickness) bags and then kept at -18±2°C till further use. Refined salt (Tata Chemicals Ltd., Mumbai), corn flour (Amrut International), potato starch (Aksher Chem) and Mono sodium glutamate were procured from local market of Guwahati. Green chili and vegetable (bean, pea and carrot) were chopped after proper washing. Black pepper, onion and garlic were grinded in mixer grinder after peeling and washing. Drying was done in the solar dryer at 60°C until the water activity was reported below 0.3.
Solar dryer was fabricated using wood consisting of a tray type drying chamber with heating filament and exhaust fan inside it; panel for collection of heat made up of glass and the interior covered with black paint coated over aluminium sheet, temperature control knob and air ventilation knob. A battery backup system was provided using a solar panel which charges a solar powered battery by converting solar energy through solar powered converter. The average temperature and relative humidity attained during peak hours of sunny days was 67°C and 22±2%. It took around 35 hours to dry the meat shred to attain required moisture level of 6±1%. Dried spent hen meat shred was prepared as given in Fig. 1.

In this experiment, formulations for instant chicken soup mix were standardized using different levels of spent hen meat shred, starches, salt and other ingredients as indicated in Table 1. Soup were prepared from instant chicken soup mixes of four formulations namely Treatment-A, B, C and D (Table 1), which fulfilled sensory attributes of consumers.
Preparation of Instant Chicken Soup Mix
Mixing of corn flour, potato starch, spent hen meat shred, salt, black pepper, onion powder, garlic powder, dried green chili, dried vegetable (pea: bean: carrot= 1:1:1) and monosodium glutamate in required proportion was done to obtain the instant chicken soup mix (Table 1). Instant chicken soup mix was then packaged in low density polyethylene (150µm thickness) bags and stored at ambient temperature.

Reconstitution of Instant Chicken Soup Mix
The instant chicken soup mix was reconstituted in cold potable water (instant soup mix: water = 1:16), stirred and brought to boil to get ready-to-drink soup.
Soups prepared from instant chicken soup mix were served at ambient temperature to the semi-trained panelists of 7- member panel. All the samples were evaluated for appearance, colour, flavour, consistency, taste and overall acceptability by using a 7 point hedonic scale.
Formulas Used in the Estimation of the Economics of Product
Assuming that, 10 kg instant chicken soup mix will be prepared in every working day and monthly working day is 25 days.
Cost of production (10 kg/day) = Cost of formulation + Overhead cost
Overhead cost = depreciation cost + Rent of building + Labour cost+ Cost of electricity + Maintenance cost + Water charge + Cost of packaging
Profit = 30% of cost of production
Income = Total sale price – Total cost of production
Break-Even point = Fixed cost × Total sales/ (Total sales – Variable cost)
Benefit cost ratio = Total sale money / Variable cost
Net profit/day = Total profit – Amount of loan payment/day
Results and Discussion
The total cost of production for dried chicken shred was calculated to be Rs. 929/kg (Table 2). The equipment cost was Rs. 45,000 (Table 3) and their annual depreciation was calculated to be Rs. 4,500/annum on the basis of 10% annual rate of depreciation (Table 4).

The break-even point was calculated to be Rs. 1,94,817.00, Rs. 1,94,169.00, Rs. 1,95,391.00 and Rs. 1,94,461.00 for Treatment A, B, C and D respectively (Table 8). Benefit cost ratio was found to be 1.30 for all four treatments. All the sensory parameters (appearance, colour, flavour, consistency, taste and overall acceptability) of the soup prepared from instant soup mix evaluated by 7-membered semi trained panelist revealed a significantly higher score for treatment C (spent hen meat shred-25%) in comparison to other treatments.
Table 8: Sensory evaluation of soup prepared by instant soup mix (Mean±SE) *
Based on the above findings, it can be concluded that up to 25% spent hen meat shred (Treatment C) could be incorporated in instant soup mix to enhance its acceptability through which a potential entrepreneur can generate Rs. 1500.00 per day as profit by producing and selling 10kg of instant soup mixes. Moreover, it will provide impetus to the food processing industry besides making healthy and nutrient enriched meat products available to the consumers and hence creating ample opportunity for employment generation.
