Manufacture of Immunity Boosting Long Life Dairy Beverages and Related Ready to Eat Products

Technology Overview

Immunoglobulins are natural antibodies that provide passive immunity, i.e. boost immunity against a wide range of bacterial and viral infections and even allergens. Immunoglobulin G (IgG) constitutes about 80 to 90 percent of immunoglobulins in bovine milk. However, high heat treatment causes a significant loss in its bioactivity and immunity boosting property due to its denaturation. Recently a novel technology has been developed to protect immunoglobulin G (IgG) against heat, thereby enabling retention of about 65 to >90 percent of its bioactivity in dairy and related products after heat processing.

The patented technology just involves use of unique powder bioactive formulations having bioactive IgG. These are reconstituted in water for the manufacture of bioactive “Ready to drink” (RTD) long life (UHT) beverages and “Ready to eat” (RTE) products on a commercial scale. These can be tailored to meet specific consumer requirements and can also be used in conjunction with other naturally occurring bioactive ingredients to get additional health benefits. The long-life beverages do not have added preservatives, have a shelf life of 3 to 9 months under ambient conditions. The bioactive products can be made with different flavours and enjoyed by both adults and children.

The technology uses low cost conventional heat processing which can be used by manufactures of dairy products and beverage / juice manufacturers, including small scale manufacturers. 

The inventor of this technology would like to collaborate with manufacturers of dairy products / beverages / juices/ nutritional supplements and license the technology for the manufacture of immunity boosting products.

Technology Features & Specifications

IgG is a heat labile protein. After heating at a temperature of 85 to 93 0C / 15 sec, it retains <10 to about 15% of its original bioactivity in reconstituted powder. A novel technology has been developed that protects IgG against heat and enables retention of about 65 to >90 per cent of its original bioactivity in dairy and related products after heating under similar conditions. The technology uses unique powder formulations and simple processing steps. It offers advantages of ease of handling, uniformity of composition, thus avoiding difficulties in handling day to day variation which is encountered in handling liquid materials. Moreover, powder can be transported over long distances and used for making bioactive products at the point of manufacture. The manufacture of RTD long life beverages and RTE products on a commercial scale involves reconstitution of powder in water, hydration, acidification and heating at relatively low temperatures (<100 0C). For RTE products like ice cream, instant desserts acidification / heating is not required. Conventional thermal processing which is low in capital cost and equipment is used which is much more economical than other non-thermal technologies. 

 The commercial products currently available in the form of powder or tablets as nutritional supplements that contain IgG can only be used for domestic consumption after reconstitution in water. The bioactive RTD and RTE products are convenient to use, have a much greater consumer appeal and can be made with different flavours. Moreover, RTD long life beverages have a shelf life of 3 to 9 months under ambient conditions.

Potential Applications

The technology can be used in the following areas:

  • For incorporating bioactive IgG in the manufacture of bioactive RTD long life acidified beverages, drinking yoghurt, juices, carbonated drinks and “drinking yoghurt with live organisms” and related products
  • RTD long life beverages have a pleasant taste, negligible fat and high protein content, no added preservatives, and have a shelf life of 6-9 months under ambient conditions. No UHT beverages having a similar nutritional profile are currently available in the market
  • The RTD long life beverages can be tailored to make a product with a 5-star health rating
  • The RTE products that can be enriched with bioactive IgG include probiotic set / stirred yoghurt, frozen yoghurt, long life yoghurt, sorbet, sherbet, hard or soft ice cream, instant desserts, juice milk spread, flans, cheese and related products
  • Both RTD and RTE bioactive products can also boost athlete’s immunity during extreme physical workout and training and help in reduction of stress.
  • Incorporation of bioactive IgG can be used in conjunction with other natural bioactive ingredients-for instance those that promote brain health, gut health or have anti-inflammatory properties
  • Hot coffee / tea, drinking chocolate can be enriched with IgG and other bioactive ingredients
  • IgG can be incorporated into pharmaceutical, health or medicinal products
  • Globally the approximate market size for immunity boosting dairy and related products is about US $ 5 to 7 billion per annum.

Customer Benefits

  • There is a great need for food products that can promote immune health against deadly bacteria and viruses like Covid19. This technology presents a unique opportunity to the manufacturers of dairy products, beverages, juices or health / nutritional supplements to manufacture and market bioactive RTD long life beverages and RTE products that are enriched with IgG alone or in combination with other natural bioactive substances. This will indeed fill the void as products with similar nutritional profile do not exist in the market place.
  • Small or medium scale manufacturers can beneficially use this technology as conventional thermal processing at low temperatures (<100 0C) which is low in capital cost and equipment is used and this is much more economical than other non-thermal technologies
  • Bioactive dairy and related products are value added premium products and can yield profitable returns to the manufacturers.
  • The technology offers significant logistical advantage and flexibility as powder can be easily transported over long distances to a specific site for the manufacture of bioactive RTD and RTE products
