在Twig模板中显示数组

Have problem to display an array in a Twig template.

In mysql I have a text field with value: testtest-testtest2-testtest3

In the controller I explode by '-' and pass it to Twig like so:

$ingred[] = explode('-', $ingreds);
$this->twig->render(['ingred' => $ingred]);

In the Twig template I loop through and it works:

   {% for ing in ingred %}
     <span class="ingridiantai">{{ ing.0 }}</span>
     <span class="ingridiantai">{{ ing.1 }}</span>
     <span class="ingridiantai">{{ ing.2 }}</span>
     <span class="ingridiantai">{{ ing.3 }}</span>
     <span class="ingridiantai">{{ ing.4 }}</span>
     <span class="ingridiantai">{{ ing.5 }}</span> 
   {% endfor %}

But what I want is to loop through all values without writing their key. Like this:

   {% for ing in ingred %}
     <span class="ingridiantai">{{ ing }}</span> 
   {% endfor %}

How can I do what? I was searching in the docs, but didn't find anything that would work for me.
