Week 16

Trail of Evidence

Project photo's

The plan is to place, side by side, all the colors of rainbow spectrum. At the beginning or behind the bioplastics I want to put down which recipe I have used and what lies where. I also want to indicate per color what is in it.

Later I tried to make a color from one fresh avocado pit. I put the avocado in the water with 2 teaspoons of crystal soda. I boiled this for about 10 minutes and got a nice red color.

I tried the blue berries again and cooked them a bit longer. The water turned red/ pink. When I added baking soda, the water turned green. I used 69,1g blue berries, 400ml water and 1 teaspoon baking soda. I let it simmer for about 10 minutes.

I cooked the same blueberries again with 400ml water with some sugar and salt. This gave a nice orange color.

Later I tried to make blue again. I boiled 93,2g red cabbage and added 500ml water and let it simmer for 10 minutes. I added a really small amount of baking soda, but the water still turned green.

I tried adding even less the second time (also after adding gelatine) but it still turned green, only less.

Later I started with cooking strawberries. I took 4 large strawberries and started to cooked them in 400ml water for 15 minutes. It turned a bit orange. Maybe if I put more strawberries in the water it would turn more pink.

I also cooked purple carrot. First i cut 5 purple carrots it in pieces and then cooked it for about 5 minutes in 400ml water. It turned blue. But after I put in the gelatine it turned purple/ pinkish. But later it turned more orange

When I cooked the purple carrot for 15 minutes, it still turned purple/ pink/ red but just a bit darker.

I also added 1 teaspoon baking soda to the purple carrot water (15 minutes) to get blue but then it turned green.

In addition to that I cooked 25 raspberries in 400ml water for 15 minutes and this gave a beautiful purple/ deep pink color. But later it turned more to red/ orange.

I also took 150ml of that raspberrie juice, added 90ml water and 1 teaspoon of cetric acid. Tis made a nice pink/ orange color.

I cooked 21 blackberries in 600ml water and let it simmer for about an hour. It turned to a beautiful red/ pink.

I also used 130ml of blackberry juice and 110ml water with a little bit of baking soda, and that gave a pink/ purple color.
