Since the OP wants both positive and negative answers for list membership, I would go with a hash: 
    my %looking_for = (Grapes=>0,  strawberry=>0);
    
    #Inside file read loop:
       for my $fruit (keys %looking_for){
          next unless m/$fruit/i;
          $looking_for{$fruit}++;
       }
    
    #-- At end of program..
    for my $fruit (sort keys %looking_for){
       print $fruit,
              ($looking_for{$fruit} ? "" : " not in list"),
             "\n";
    }
