What is the closest equivalent Japanese word to "melempem"?

Question

How do you describe this state of 'melempem' in Japanese?

This is the food (kerupuk) in question:

Melempem = a state of condition of something that lacks 'hardness' due being out in the open for some time, has gone soft and not crunchy anymore, usually used in cookies, fish/shrimp chips, or belinjo chips. Usage: usually to describe a food.

In Japanese, it's the opposite of 'かりかり' or means lacking stiffness/firmness/something that has gone limp and soft due to exposure to air.

Can we say: 不干な(ふかんな)?

Thanks!

Answer 1

Judging from your description, I think the word you're looking for is 湿気る【しける】 (verb). You can modify a noun using this word like 湿気たクッキー or 湿気ったクッキー. You can find many articles on the net about how to restore 湿気たクッキー to its original crisp status.

不干な makes no sense to me. 湿る【しめる】 is another option, but it's primarily used for towels and such.

EDIT: If you want mimetic words, there is a word しっとり. But this does not have a negative connotation, so you usually have to use it with ～てしまう, for example しっとり(と)してしまったクッキー, to indicate it's undesirable. ベトベト also might work if it's really moist.

Answer 2

For sponge cakes, we might say "ふっくら" or "ふんわり" for the condition. It's soft and its inner part gets hollow. When you taste it, it's a little bit hard to chew it.

For hairstyle, we might call "もっさり" when we wake up in the morning and before brushing and hairs get tangled and rising up a bit.

I don't have 不干な(ふかんな) in my vocabulary. I might guess something is not dry, however.

Edit:

So, if you want to say rice cracker or seaweed contain too much water, we might call "べっちゃり"　or "べちゃべちゃ".
