Squeezing Orange

saraclark62

Whenever my brother squeezes oranges to make fresh orange juice, I like to eat the pulp that is left behind. Obviously since the juice has been squeezed out, just the pulp remains and isn't that juicy. I am having trouble logging this because I don't know if it would still contain the same number of calories as a regular whole orange. There isn't much since all the juice is gone. What do you think ? Thanks!

Don't eat left-overs?

I suppose you can sit there and look up the usda standard reference entry for orange juice by gram; orange raw without peel; and then calculate the difference between the two and come up with an approximate number for partial pulp.

Whether that is worthwhile... is another story.

YOU HAVE TO WEIGH YOUR ORANGE PULP

jk I don't know. Maybe just stop doing that it sounds gross. Also jk.

Weigh the leftover on a scale but since most of the calories are missing it couldn’t be much.

create an entry by subtracting the USDA nutrient database values for orange juice, raw, using the "1 fruit yields" serving (or, if you can weigh the juice before your brother drinks it and divide by the number of oranges he juiced, you could adjust the values based on the average per-fruit weight of the juice --
USDA is assuming 86 g of juice per fruit) from the USDA nutrient database values for oranges, raw, all commercial varieties (or the specific variety, if you know that), using the per-fruit serving size based on the average weight or size of the oranges your brother uses.

For a rough ball park figure, the USDA NDB lists 86 kcal for a large orange and 39 kcal for the juice (86 g) of one fruit, leaving 47 kcal in the pulp, which is more than I would have expected.

And for moral support, it doesn't sound gross to me. I don't juice oranges very often, but I have occasionally eaten the "used" pulp when I did. And I do it all the time with lemons.

Haha, weigh the pulp

Of course you should weight the pulp!

And use a value of approximately 23Cal per 45g (slightly off from @lynn_glenmont 's values )

https://ndb.nal.usda.gov/ndb/foods/show/2284?manu=&fgcd=&ds=Standard Reference
A "standard fruit", edible portion, is 131g and ~62 Cal
https://ndb.nal.usda.gov/ndb/foods/show/2289?manu=&fgcd=&ds=Standard Reference
A "standard fruit" yields about 86g of juice worth ~39 Cal

Therefore, the pulped left-overs after the sqeezing of the juice out of a "standard fruit" would be about 45g and ~23 Cal.

Not really that much off from my values -- I was trying to get to a rough approximation of the "per-fruit" value for the pulp, but if you look at the underlying weight for the value of a large fruit (which I assumed because I find most grocery-store produce tends to be "large" by USDA standards), you're looking at 98 grams of pulp for the 47 kcals, which is pretty darn close to 45 g and 23 kcals.

Isn't it nice when two different approaches yield approximately equal results?

But to the extent that there's a difference, if OP doesn't want to actually weigh the whole fruit and the juice (which would be a pain in neck, come to think of it, because "whole fruit" weight on USDA NDB is just the edible parts, and most juicers I'm familiar with operate with the peel still on, so OP would have to weigh the whole fruit (A), then the juice (B), then the remaining peels after eating out the pulp (C), and subtract C from A to get the edible part (D), then subtract B form D to get the pulp weight ... ) ... I think OP should use your number, since hopefully the USDA NDB uses the same "standard fruit" for the whole fruit and juice entries. I expect the type of fruit (whether brother is using juicing oranges or the navel oranges that often are all I see in the grocery stores) will make a difference.

Given the above responses, i would just log quick calories 23 per orange that you do this with.
