Emacs org-mode - Export to html without syntax highlighting

I'm using org-mode to write blog post(wordpress). Because I'm using a plugin for syntax highlighting, I don't need to use org-mode's syntax highlighting.

Here is example.

Source in emacs. enter image description here

Exported output. enter image description here

When I remove language field followed BEGIN_SRC, syntax highlighting is also disapeared. But I just want to disable syntax highlighting only when exporting without removing language field(emacs-lisp).

Also I tested below, but it does not work.

(setq org-src-fontify-natively t)

============ UPDATE ============

I applied below. (Thanks @Picaud Vincent) (setq org-html-htmlize-output-type 'nil)

It works fine with source block without language field. But It does not work with source block with language field.

here is example.

In .emacs file.. (setq org-html-htmlize-output-type 'nil)

  1. without language field origin

#+BEGIN_SRC
      (setq org-todo-keywords
            '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED")))
#+END_SRC

exported

<pre class="example">
    (setq org-todo-keywords
          '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED")))
</pre>

  1. with language field origin

#+BEGIN_SRC emacs-lisp
      (setq org-todo-keywords
            '((sequence "TODO" "FEEDBACK" "VERIFY" "|" "DONE" "DELEGATED")))
#+END_SRC

exported

<div class="org-src-container">

<pre class="src src-emacs-lisp"></pre>

============ UPDATE ============

Finally, I found solution.

  1. Follow @Picaud Vincent' answer. (setq org-html-htmlize-output-typenil)`

  2. If There is no code in source block with language field, add exports: code to language field. ex> #+BEGIN_SRC emacs-lisp:exports code

Although adding 'exports: code` disables syntax highlighting in org-mode buffer, but it solve my problem.

Maybe you can try to customize the org-html-htmlize-output-type variable:

Usual HTML export looks like:

enter image description here

however, with this customization 

(setq org-html-htmlize-output-type `nil)

you get plain text:

This variable and other customizable ones are defined in the ox-html.el file.

Update: complete html sources

Before:

<div class="org-src-container">

After:

  :type '(choice (const css) (const inline-css) (const nil)))
