Donations and tithes on fruits and vegetables

I understand that the Treasury keeps the coin (maybe later causes it to be lost) so there is monitoring of this coin because it is prohibited from use.
For those who tithe one-time, there is a reasonable chance that they will forget and use this coin at some point
Is there an option to desecrate the sanctity of the coin on fruit and then put it in a bag and throw it away, and thus the coin is actually more usable?
Thank you

It is not permissible to desecrate the coin on fruit because the coin is forbidden in pleasure for the impure. However, it is permissible to desecrate the coin on food as it is worth money and lose it (according to the law, it is forbidden to lose coins).
I am copying from my halakha here (http://ph.yhb.org.il/07-12-10/) Note 7 that is relevant to our case:

For example, if a shekel coin is set aside for this purpose, he can desecrate it about twenty times, according to the calculation that a penny is approximately five agorat. After he desecrates twenty times, he can desecrate all twenty pennies in the shekel on one penny in another coin. And the best way is to set aside two coins, one of five shekels and one of a shekel (I usually stick them with tape, to mark them), and he will always desecrate on a penny in the large coin, and every so often, he will desecrate all the pennies in the large coin on one penny in the small coin. And then he will exchange all the pennies in the small coin for one pennie in the large coin, and thus he will be able to redeem the coins he has set aside for this purpose over and over again. And even if he has family members or friends who make it difficult for them to keep a coin in their safe drawer, he can give them permission to exchange a penny in his large coin, and he will make sure to return all the pennies to one penny every few months. And twice in a seven-year cycle, he must exchange that penny, on the eve of Passover of the fourth year, and on the eve of Passover of the year of the Sabbatical. This is how it can be done: he will take a spoonful of sugar, stand by the sink, say, "All the pennies in my coins are exchanged for the sugar in the spoonful (which is worth a penny), and pour water on the sugar, and thereby lose the sugar."

A. They have a ‘hard penny’ in their coins, which is consumed when they desecrate a name that has no penny equivalent.

B. They have an arrangement for giving the poor tithe, by way of a loan in advance to the poor from which all tithes are deducted.

Indeed, that is true. I should have added that one should take care of a severe penny. Here is its description:

Chazal determined that one does not desecrate a second tithe that is not worth a penny unless the coin that is being desecrated now has already been desecrated in the past with a second tithe worth a penny. Therefore, one must ensure that the first desecration made on the coin will be worth a penny.
Since there are different degrees of liability in tithes, such as a person who grows fruit in his field - his degree of liability is more severe than a person who buys in a store. Similarly, the degree of liability for grain, wine and oil, i.e. wheat, wine and oil, is more severe than the degree of liability for other fruits and vegetables, therefore it is impossible to desecrate a second tithe that is worth less than a penny with a higher degree of liability on a coin that was desecrated for the first time with a second tithe whose degree is lower than it.
Therefore, when a coin is set aside for the desecration of a second tithe, the most severe degree of a second tithe must be desecrated on it for the first time, namely a second tithe worth a penny, which was grown in one's possession and not purchased, and which was made from grain, wine, and yitzhar, and also whose completion of the work was done with the consent of his eater.
