what is the process of food fermentation of bagoong?

Answer 1

"Preparation techniques can vary greatly; however, the following procedure is most common in China, and much of Southeast Asia.

'After being caught, small shrimp are unloaded, rinsed and drained before being dried. Drying can be done on plastic mats on the ground in the sun, on metal beds on low stilts, or using other methods. After several days, the shrimp-salt mixture will darken and turn into a thick pulp.

"If the shrimp used to produce the paste were small, it is ready to be served as soon as the individual shrimp have decayed beyond recognition. If the shrimp are larger, fermentation will take longer and the pulp will be ground to provide a smoother consistency. The fermentation/grinding process is usually repeated several times until the paste fully matures. The paste is then dried and cut into bricks by the villagers to be sold. Dried shrimp paste does not require refrigeration." (1)
