DESC:FIELD OF INVENTION:
The present invention relates to a plant based vegan protein drink, which is a unique combination of various plant proteins, enriched with real fruit juices, vitamins and minerals. Particularly, the protein drink of the present invention is free of non-GMO protein, lactose, animal protein, gluten, allergen and has reduced fat content and cholesterol that gives complete nutritional value and works as a complete meal replacement. The protein drink of the present invention which is rich in amino acids also has good digestibility.

BACKGROUND OF THE INVENTION:
Proteins are biological amino acids which are found in all cells of the human. Proteins in the human organism perform a variety of functions such as they act as antibodies to the defence of infections, used for the production of muscles, used to manufacture hormones, enzymes, cellular messengers, nucleic acids, and immune-system components. Without adequate protein, our bodies cannot put together the structures that make up every cell, tissue, and organ, nor can it generate the biochemical substances needed for cardiovascular function, muscle contraction, growth, and healing. Overtraining of muscles could lead to injury and hence muscles require adequate supplement of protein to heal up quickly.

A variety of protein drinks are currently available in the market and are consumed for variety of purposes, ranging from assisting in weight loss to supporting muscle growth to enhancing general athletic performance. A section of the consumers purchase the protein drink with no specific purpose in mind or have no knowledge of the purpose of the protein drink which they consume. Most of the protein drinks are formulated with certain purposes so as to benefit the consumer.
Majority of health drinks are animal or milk based drinks. The major problem with high intake of animal or milk based drinks is increased risk of cardiovascular diseases. The other major disadvantage is most of the animal or milk based drinks is their allergenic nature. Moreover, milk based drinks are not suitable to people who are lactose intolerant.
The protein drink of vegetable or plant based appeals to all vegan, vegetarian and non-vegetarian consumers. The protein drinks of vegetable origin reduce the levels of saturated fats and cholesterol causes less side effects, are as effective as whey protein in helping one build muscle, gain strength and recover from exercise. However, the currently marketed vegetable or plant based protein drinks do not fulfil the nutritional requirements and the digestibility issues.

US20080206430 discloses a vegetarian nutritional supplement comprising a blend of soy protein, rice protein and pea protein. The nutritional supplement is provided in US’430 to have effective relative digestibility comparable to whey and flavour and texture comparable to isolated soy protein. However, the said nutritional supplement does not fulfil the requirements of vitamins, minerals, carbohydrates required by the human body. Moreover, many reports suggest that the soy protein causes hormonal imbalances in men depriving testosterone and promoting the production of oestrogen, produces abnormal enlargement of mammary gland in men, can also alleviate hot flashes in some menopausal women. Further, soy contains isoflavones which act like estrogen in the body. Since many breast cancers need estrogen to grow, consumption of soy protein could increase breast cancer risk in certain women.

US20120128832 relates to Organic Vegan Protein sports drinks and shakes formulated from 100% organic and natural plant-based ingredients with protein, vitamins, minerals and other nutrients. The Organic plant proteins used in the drinks and shakes are predominantly, Organic Hemp Powder, Organic Pea Powder and Organic Vegan powder (made from a mixture of Organic seed sprouts) Organic Soy milk and Organic Almond milk.

A need still exists in the art to provide vegetable or plant based protein drink which is highly nutritious and contains essential amino acids, carbohydrates, essential vitamins and minerals required by the human body with easy digestibility such that the drink is a complete food in itself and can be given as a meal replacement. The other objective is to provide protein drink which is favourable to all types of consumers which is rich in amino acids, contains Fruit Juice, vitamins and minerals.
