CHIPPED RICE

Very, very significant. Sudama Vipra's offering of chipped rice. It is said the chipped rice was actually not even offerable. So why did Krishna accept it and taste it with such relish? Sudama Vipra had no other desire than to always remain surrendered to the Lord. He was very poor but did not come to the Lord for wealth. He approached the Lord to satisfy his wife, but he was only thinking of surrendered service to the Lord not for his own aggrandizement in any way. Krishna took just one grain and Rukmini devi had to stop the Lord from tasting any more. That one grain was enough to bestow unlimited mercy on the brahmana and the entire creation. This is very significant.

"I consider that this quantity of chipped rice will not only satisfy Me, but will satisfy the whole creation." It is understood from this statement that Krishna, being the original source of everything, is the root of the entire creation. As watering the root of a tree immediately distributes water to every part of the tree, so an offering made to Krishna, or any action done for Krishna, is to be considered the highest welfare work for everyone, because the benefit of such an offering is distributed throughout the creation. Love for Krishna becomes distributed to all living entities. KB 2.26
And the obverse... Those who have no devotion may offer very valuable items but the Lord is not interested. He does not accept such offerings.
"On the other hand, if a person is not a devotee, even though he
may offer Me very valuable things, I do not like to accept them. I actually accept only things which are offered to Me in devotion and love; otherwise, however valuable the thing rnay be, I do not accept it." KB 2.26
