Orange juice study

As we have an orange juicer now, we did a sunday morning study of three different orange products.

So in the study we had the following products:

Name	Valensina Juice oranges	ALDI oranges	riodoro blood oranges
Weight [kg]	1,5	2	1,5
Cost [€]	2,99	2,49	2,19
Price [kg/€]	1,99	1,25	1,46

Now we wanted to see which taste best, but as we were on it, I also did quantify some more metrics of a random sample of 2 oranges each.

This can be seen in the following table which includes weights and the important juice percentage:

Name	Valensina Juice oranges	ALDI oranges	riodoro blood oranges
weight of 2 oranges [g]	341	435	228
weight of the juiced oranges [g]	162	207	84
weight of the fruit pulp [g]	64	28	31
juice [g]	115	200	113
juice percentage [%]	33,6	45,9	49,6
cost per juice [€/kg]	5,91	2,72	2,94

So it can be seen, that the Valensia oranges are the most expensive, yet do not give as much juice as the others. I found it quite interesting, that about half of the blood oranges was extracted as juice which is very good.

I did not check the density or measure the amount of liquid, so I can not calculate the price per liter.

But we did not only include the easily quantifiable metrics, but also the taste to measure the quality. I had two other test persons here so that we have a small jury of the oranges which gave points on a scale of 1 to 10:

Name	Valensina Juice Oranges	ALDI oranges	riodoro blood oranges
Jury 1	8	8	10
Jury 2	7	9	10
Jury 3	8	9	10
overall	7,6	8,6	10
fruity	x	xx	xxx
bitterness	xxx	x	xx
watery	xxx	xx	x

Final results

The blood oranges had the maximum score of a 10/10 and have a price of 2,94€/kg juice which is quite near to the 2,72€/kg of the other oranges.

Though as the blood oranges are much smaller than the ALDI oranges it takes more effort to juice the orange but normally my own labour cost on a sunday morning is not that expensive for me.
