Process for the preparation of an additive as a food supplement based on seaweeds for birds and animals; as well as the product obtained and its use in the food conversion and in the production of bird and animal meat
The present invention relates to a process for preparing an additive as a food supplement based on algae for birds and animals. It also describes the food additive obtained, formulated with seaweed extract, whey, malto-dextrin, proteins, amino acids, minerals, fiber, fat, hormones, and has a final powder form. In addition, the use of the food additive to increase the weight gain in animals, the weight gain in eggs of birds, and for the production of meat in birds and animals is described.
1. A process to prepare a dietary supplement for animals based on seaweed, wherein comprises the steps of:
a. Selecting and washing the seaweed;
b. Grinding the seaweed;
c. Adding hot water and steam;
d. Acid treatment of the seaweed;
e. Washing the seaweed after the acid treatment of step d) and incubating with water;
f. Adding whey during the water incubation period of step e);
g. Applying an alkaline treatment with constant agitation;
h. Adding hydrolyzed starch during the alkaline treatment of step g);
i. Filtering to separate a solid phase from a liquid phase;
j. Concentrating the liquid phase under vacuum;
k. drying until the obtention of a powder product;
l. Finally, pack and store the product obtained.
2. Process according to claim 1 , wherein the seaweed selected in step a) comprise Durvillaea sp., Macrocystis sp., Porphira sp., Ulva sp., or combinations thereof, from which 1,000 kg are weighted and 30 minute washes are applied in a liquid:solid ratio of 2:1 to extract salts and impurities.
3. Process according to claim 1 , wherein the seaweed from step b) is ground in a screw or knives mill until reaching a particle size between 0.5 and 1 cm.
4. Process according to claim 1 , wherein during step c) for every 1,000 kg of the seaweed of step a), 2,000 L of hot water at a temperature between 50 to 60° C. are added with steam inclusion, mixed in a 5,000 L capacity tank.
5. Process according to claim 1 , wherein during stage d) 50-70 L of apple vinegar is used for every 1,000 kg of initial seaweed and then 50-70 L of acetic acid are added for every 1,000 kg of the seaweed of step a).
6. Process of claim 1 , wherein during step d) the acid treatment occurs at a pH of 2 to 6.5.
7. Process according to claim 1 , wherein step e) comprises the incubation in water at a temperature of about 45-65° C. for about 90-120 minutes.
8. Process according to claim 1 , wherein in step f) between 90 to 108 kg of whey are added for every 1,000 kg of the seaweed of step a).
9. Process according to claim 1 , wherein during step g) between 45-50 kg of K 2 CO 3 are used for every 1,000 kg of the seaweed of step a) and it is incubated between 70-80° C. for about 120-150 minutes.
10. Process according to claim 1 , wherein in step g) the alkaline treatment occurs at a pH between 8.5 and 14.
11. Process according to claim 1 , wherein in step h) 50 to 54 kg of hydrolyzed starch are added for every 1,000 kg of the seaweed of step a).
12. Process according to claim 1 , wherein step i) comprises filtering the alkaline extract with a 250 microns filter.
13. Process according to claim 1 , wherein step k) comprises drying the product by spray drying at an inlet temperature of about 150 to 170° C. and an outlet temperature of about 70 to 80° C.
