  3. Soak in 33% brine for 3-6 hours.
  4. Drain the water from the fish and arrange on drying trays.

Because of oversupply, vegetables and fruits in season often wilt and spoil in our
markets. The producers are forced to sell cheap and get only a small profit. By processing and preserving abundant, in season fruits and vegetables, people can sell these at much higher prices during the off-season.

Preservation makes vegetables and fruits more palatable.Here are some of the methods:

A. Dehydrated Carrots

1. Select fresh mature carrots with deep orange color, free from woody fiber.

2. Wash thoroughly in running water.

3. Peel and dice into 4 mm. x 10 mm. x 10 mm. cubes.

4. Arrange in wide nylon or sinamay basket and blanch by exposing to live steam over rapidly boiling water for 3 minutes.

5. Immerse the blanched carrots in cooked cornstarch for one minute.

6. Drain the cornstarch and arrange carrots in trays.

7. Dry in a cabinet dryer at 60-65° C for 7-8 hours, or under the sun until the pieces of carrots show no moisture when pressed between the fingers.

8. Pack in plastic bags and seal.   

B. Dehydrated sitaw

1. Cut sitaw into desired lengths.

2. Steam for 5 minutes.

3. Dry in a “forced airdraft oven” at a temperature of 60°.

C. Complete dryness is show when it becomes crispy.

The dehydrated beef blood with a protein content of 80-82% protein has a shelf life of five (5) months when packed in polyethylene bags. They may be also be fortified with vitamins. Dehydrated beef blood could be incorporated in recipes or in the preparation of high protein biscuits, curls and others.

Beef blood Equipment:

  • Containers
  • Meat grinder
  • Trays
  • Pulverizer


Two methods of preparing dehydrated beef blood are as follows:

  1. Collect beef blood in a very sanitary manner by using thoroughly clean containers and collection cups. Steam for 20 minutes, grind in a meat grinder and dry in aluminum trays at 60° C until thoroughly dry. Pulverize the dried product into powder.
  2. Pass the beef blood through a grinder to break the clots, dry in aluminum trays coated with an edible wax (to prevent sticking) at 60° C for the first 2 hours, then at55° C during the succeeding hours until thoroughly dry. Grind the dried product into powder.

The dried dilis is made crispy to deep frying toasted dilis coated with cornstarch. Crispy dilis is tastier compared to dried dilis and is eaten directly from the pack.               

Raw materials:
Dried dilis           
Egg yolk           
Cooking oil           
Spices (black pepper, siling labuyo, salt, vetsin) to taste


Frying pan   


Toast dried “dilis” and set aside to cool. Coat cooled “dilis” first with the mixture of salt, beaten egg yolk, vetsin and spices; and then with cornstarch. Deep fry the coated “dilis” for a few seconds. Cool and pack in polyethylene bags.

1 tsp. sugar    


Chopping board   
Measuring spoon   
Pressure cooker (in the absence of a pressure cooker, a casserole may be used)  
Measuring cup (liquid)   


1. Wash meat thoroughly. 

2. Cut the meat into 1 inch cubes.
3. Mix the salt, vetsin, prague powder and sugar.  

4. Mix the curing ingredients with the cubed meat.  

5. Place in covered container and cure in the refrigerator for 3-4 days.  

6. Wash the meat, add water (1/3 of its volume) and cook for 20 minutes.Remove the foam-like formation on the broth.  

7. Continue boiling until meat is soft and tender, for faster cooking use a pressure cooker and cook beef for 30 minutes at 10 lbs. pressure.  

8. Drain and cool.  

9. Flake with fork. (The flaked meat is ready for consumption). For longer storage period, follow procedures 5, 10 to 15.  

10. Pack meat into bottles/cans and add broth, leave 1/4 inch head space.  

11. Exhaust bottles/cans by boiling it with covers slightly closed.  

12. Seal thoroughly.  

13. Process at 10 lbs. pressure for 10 minutes.  

14. Air-cool cans should be cooled under running water while air-cool bottles at room temperature.  

15. Label and store in a cool place.

Sweetened condensed coco milk is usually used as beverage, sandwich spread, and coffee creamer.   

Raw Materials:
Grated coconut milk
Refined white sugar
Agar-agar or 1/4 bar gulaman

Mixing bowl/basin
Measuring cup
Plastic container
Measuring spoon
Wooden spatula
Double boiler


Cream is extracted from the grated coconut meat by pressing. The “sapal” or residue added with proportional amount of water is extracted once more to obtain the skim milk (lower layer) by separating from its cream (upper layer) through gravity. One and a half parts sugar is mixed with 1 part skim milk and the remaining cream of the second extract is added to the first pure cream extract for purposes of producing oil. However, if there is no intention of processing oil from the cream, sugar is dissolved into the liquid after second extraction. The sugar mixture is cooked with continuous stirring for one hour in a double boiler. To thicken the mixture, agar-agar or 1/4 bar gulaman is added. The produced sweet condensed coco milk is poured in sterilized bottle and then sealed.
