There are colloquial usages of 'value' that make this conversation more complicated. We might describe the value as the utility or desirability of the object -- use value -- where I value food because I can eat it. Or the exchange value, ie, how many apples is this iron worth. Or the labor value, ie, how much labor went into producing this item. Or the price, ie, how much is this item worth in money. It seems that in reading this sentence, the author is talking about the labor value of the fruits. The various parties may have different ideas about exchange values, prices, and use values, but the labor value doesn't change because the items have exchanged owners.
