whats an easy to come by agar recipe?
« on: September 10, 2014, 04:05:14 AM »
Was wondering a simple but healthy agar recipe for oyster mushrooms? I'm kind of limited to smaller family owned shops. I will need to use a small jar there is no way I can get them plates for the agar. Please feel free to share your ideas on this, thanks again.

You can use mashed banana instead of agar + sugars but I have not tried yet

You don't have to use petri dishes, small Polypropylene (PP, recycle number 5) plastic containers are your friend and mine.

Like these:


Agar...it's actually available in a wide variety of stores, just ask for it.  You can always order it via the internet, or someone here could post you some perhaps.

Also I heard it is better to buy korean or french agar than japanese due to increased radiation levels since fukushima (agar is made from algae).

Is it really from algae?  I thought it was seaweed.  OK maybe I have no idea where algae stops and seaweed begins.

I too use those little polypropylene sauce container too with great success. Very cheap, won't smash, are autoclaveable, and are reusable.

Thanks, I wouldn't of guessed it be in stores. Is agar a food supplement or something?  I have containers like this not sure if it polypropylene, I can try for some new ones. I'm guessing there good in the cooker and that's what autoclaveable is I think. I'm read some more up on agar tonight, thanks again everyone.

Yes, agar is a powder that is added to foods to make jelly, it is an alternative to gelatine. 

You have to use polypropylene because, as you guessed, it can handle the 121 degree C temps inside the pressure cooker. 

Here is a photo of the triangle 5 you are looking for (5 is food grade polypropylene)

Well i learnt something about what the numbers stand for tonight :P. The diff between seaweed and algae is not much NSF haha. I've been on a hunt to harvest some seaweed for myself and checked in on a marine sanctuary to find the answer.. long story short, i'm still struggling to find it(agar) around this coastline.
For $2-3 for a packet in any asian grocer, it's worth buying. If you can't find any, here's some for decent price/delivery (i wouldn't normally advocate purchasing this on ebay, but since you won't be eating it yourself, it should be ok)

Here's hoping it's tea Lau :P .
Shrooman- I usually use that one for eating as it's easy to buy from shops around here, and generally around the $2mark, which is good for that amount!

NSF - So can the PP5 plastics really hold up in a pressure cooker @ 120degs? I'm always worried when i pour near boiling food stuff/water into them

I use the same on Shrooman. 

golmuso - yeah PP has no problems in a PC (unless you boil it dry...sigh...I've done that far too often). 

A quick google came back with these data points:

Maximum Temperature: 275F 135C
Minimum Temperature: 32F 0C
Autoclavable: Yes
Melting Point: 338F 170C
Tensile Strength: 4,500 psi
