Changing the RSS feed titles not working

Question

I'm trying to change my RSS feed titles to display the post type beforehand but it's not working.

Code below. Any ideas?

Thanks

function changeRSStitles($content) {

global $post;

if (get_post_type($post) == 'literature') {
    $content = 'Literature: '.$content;
} else if (get_post_type($post) == 'recipe') {
    $content = 'Recipe: '.$content;
} else if (get_post_type($post) == 'restaurant') {
    $content = 'Restaurant: '.$content;
} else if (get_post_type($post) == 'post') {
    $content = 'Sugar Street Blog: '.$content;
}else {
    $content = $content;
}

return $content;
}

add_filter('the_title_rss', 'changeRSStitles');
