Post-Harvest Technology

      The basic and applied research in this Division includes egg and poultry meat quality evaluation; development of innovative techniques for their preservation; development of value-added poultry products tailored to market requirements, their packaging and self-life evaluation under different storage conditions; assessement of potent bio- and phyto-contaminants as well as processing and utilization of poultry by-products, etc.This division has a semi-automatic poultry processing unit, rendering unit and its laboratories are well equipped with modern meat/egg processing and analytical equipments.

Research Activities & Achievements

Post-harvest loss assessment:

  • Quantitative losses occuring in eggs and market-ready broilers (5-7 weeks) at selected poultry farms, marketing channels (wholesale/ retail), egg processing plant and house-hold consumer's level assessed through random sample survey.

Quality evaluation :

  • Carcass characteristics including meat yields as well as meat and egg quality of different genetic stocks of diversified poultry species maintained at the Institute have been carried out.
  • Effect of growth hormone and myostatin genes affecting body weight in broilers evinced that fast growing broilers possess relatively less organoleptic quality than normal growing broilers.

Processing:

  • Optimum pre-slaughter fasting period and pre-slaughter electrical stunning to address poultry welfare concern during processing, scalding time and temperature combination and chilling methods, etc. for primary processing of poultry have been standardized.
  • Hot deboning, comman salt and polyphosphate treatments of poultry carcasses resulted in energy saving and reductionn in processing time.
  • Enzymatic method for the tenderization of meat from spent hens/culled breeding stocks have been evolved.

Preservation:

  • Developed preservation technology for poultry meat through curing and/ or smoking, organic acid dip and usage of natural preservatives (extracts of spices and condiments) .
  • Optimized oil-coating, referigerated storage and brining of shell eggs for extending their shelf-life.

Value added products:

  • A number of value-added meat products such as chicken sausages, patties, nuggets, mixed meat loaf, steak, rolls, cooked meat stock, gizzard snacks, chicken gizzard pickles, chicken skin-meat cutlets, intermediate moisture chicken meat, gizzard and quail meat pickles, etc. as well as egg products viz. albumen flakes, pancake, egg patties, egg pizza, egg crepes, egg roll, egg strips, egg waffles, egg soufflé, egg cutlet, brined and pickled eggs developed and their shelf-life assessed. Over half a dozen processes developed in this regard have been commercilized.
  • Processes also optimized for the utilization of low-value carcass components such as skin, gizzard, heart, liver and wings as value-added meat products.
  • Developed poultry meat based functional foods.
  • Evaluated comparative efficiency of some flexible packaging materials as an alternative to conventional rigid containers, and modified atmosphere packaging for shelf-life extension of convenient poultry products.

Quality assuarance:

  • Microbiological quality of poultry meat and processed poultry products assessed.
  • Conducted surveillance and optimized PCR based detection techniques for some potent pathogens like Salmonella enteritidis and S. typhimurium, E coli, Staph aureus  and Campylobacter  in chicken eggs.
  • A few bacterial pathogens in chicken eggs were quantified using Real–Time PCR.
  • Antibiotic resistant profile of these pathogens was generated and techniques for decontamination of chicken eggs using generally regarded as safe (GRAS) preservatives were standardized.
  • Occurrence of residues of some potent pesticides ( BHC, DDT, Elderin, Dieldrin, Chloropyrophos, Monocrotophos, Dichlorovos, etc.), heavy metals (As, Pb, Cd, Mo, etc.) and vety. drugs (tetracycline, enrofloxacin) in samples of meat, liver and adipose tissue of chicken from farm and market samples collected from northern and eastern region of the country was determined and found to be below their respective MRLs.

By-product utilization:

  • Conversion of poultry slaughter by-products into feather meal, offal meal and mixed by-product meal optimized and their nutritive value evaluated for incorporation in poultry rations.
  • Technique for preparing pet food biscuit for adult dogs and semi-moist patties for pups utilizing poultry slaughter by-products developed, nutritive value evaluated and successful feeding trials conducted.

Technology Developed

Process for tenderization of poultry meat:
To overcome the disposal problem associated with tough meat of spent hens/ culled breeding stock, a simple and cost-effective process for post-slaughter enzymatic tenderization of meat has been developed. Chicken carcasses are soaked for 3 hr in a tenderizing solution containing papain, sodium chloride and polyphosphate to make tough poultry meat tender.
Oil-coating preservation of eggs:
Eggs are spray-coated with edible vegetable oil (groundnut oil)containing anti-oxidant or liquid paraffin. About 7500 eggs can be coated with one litre of oil and such treated eggs can be safely stored for 30 and 120 days at mean ambient (31°C) and refrigeration (5°C) temperatures, respectively.
Process for poultry carcass decontamination using acidified sodium chlorite:
Acidified sodium chlorite (ASC) is a GRAS (generally recognized as safe) food preservative. Chicken carcasses can be dipped in 0.01% ASC solution for 3 min. for effective decontamination against Salmonella, Campylobacter and cytotoxigenic E. coli.  

Value added egg products

Pickled eggs: A simple, cost-effective and efficient technology developed for pickling of quail eggs for upto 4 months of storage and marketing at ambient temperature in ready-to-eat form.
