I tried with the following code. 
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

my %hash_table;
my $name;


my $file = '/tmp/fruitdir/fruit1.txt';
open my $fh, "<", $file or die "Can't open $file: $!";
while (<$fh>) {
    chomp;
    if (/^\s*fruitName/) {
        ($name) = /(\".+\")/;
        next;
   }
   s/(fruitCount|fruitValue)/$name\.$1/;
   my ($key, $value) = split /\s+/, $_, 2;
   $hash_table{$key} = $value;
}
print Dumper(\%hash_table);

This is not working and i am getting the following output. 
$VAR1 = {
          '' => undef,
          'time' => '11:15    ',
          'date' => '14/07/2016',
          '{' => undef,
          '#' => 'this is a new file',
          'total' => '30    ',
          'end' => '11:20    ',
          'No' => '"FRUITS"',
          'Fruit_class' => undef,
          '}' => undef
        };
