Fermentation breaks down organic substances into simpler components through enzyme action and microorganisms. When it comes to seafood, this process creates two main products fish sauce and fish paste.
Fish sauce (patis) is produced by hydrolyzing small fish for 6-12 months. The result is a clear, amber-colored liquid with a distinctive flavor coming from free amino acids like glutamic acid, alanine, and lysine, plus organic acids like lactic and acetic acid. This delicious condiment goes by different names across Asia nuoc mam (Cambodia), nam-pla (Thailand), and patis in the Philippines.
Fish paste (bagoong) is the undigested residue left from partially liquefied fish. It's made from whole or ground fish, shrimp, or shellfish mixed with salt and fermented for weeks or even a year.
Quick Fact The unique flavor of these fermented products might come from halophilic bacteria that thrive during the fermentation process!
A good fish paste has a slightly fishy, cheesy odor with fish that's partially or completely broken down. It should have a pasty (not watery) consistency, ash to reddish color, and a pleasing taste that isn't too bitter, sour, or salty. Fish paste has regional names including trassi (Indonesia), belacan (Malaysia), and buro in the Philippines.
Buro represents a special category of fermented products with added carbohydrates like cooked rice. Burong Isda contains fish while Burong Hipon contains shrimp.
You can speed up fermentation through several methods. Physical means include using elevated temperatures , regular stirring with wooden paddles, and grinding the fish to increase surface area for enzymes to work. This is why some traditional methods involve specific tools and techniques!
Science Connection Temperature matters in fermentation! Warmer temperatures significantly speed up the rate at which fish flesh breaks down during fermentation.
Grinding fish increases its surface area, allowing natural enzymes to work more efficiently. This technique is especially useful when making fish paste without solids or fish sauce.
Adding enzymes is another way to accelerate fermentation. Plant proteases like bromelin from pineapple and papain from papaya help break down proteins. Animal-derived enzymes like pepsin and trypsin work similarly. Even the fish's natural enzymes (trypsin and cathepsin) contribute to the process.
Certain microorganisms can speed things up too. Proteolytic bacteria (Brevibacterium, Bacillus, and Micrococcus species) and proteolytic molds (Aspergillus oryzae) help hydrolyze fish flesh faster.
Try This Next time you're in a grocery store, look at the ingredients in Asian fish sauces. You might spot some of these natural enzymes or fermentation accelerators on the label!
Burong Isda comes in two main varieties white (natural color) and red (colored with angka or angkak). White burong isda is preferred in western Luzon provinces, while the red variety is popular in eastern Central Luzon. These regional preferences show how fermentation techniques develop unique cultural identities.
Burong hipon (fermented shrimp with rice) is known by several names including balao-balao and tagbilao in Central Luzon. Interestingly, balao-balao naturally turns red when it reaches the proper fermentation stage.
Preventing spoilage is crucial for successful fermentation. Bacterial spoilage occurs when spoiled fish or insufficient salt is used. Mold growth can happen when impure salt is used in the process. Proper ingredients and cleanliness are essential for safe, delicious fermented products.
Food Safety Alert Always use fresh fish and the correct amount of salt when making fermented fish products at home to prevent dangerous bacterial growth!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
