What do you mean by "broke"? Is that supposed to be "hydrolyze"?
Why don't you first check the literature, especially the patents? This is a well documented industrial process. Checking the references found in
Kirk-Othmer's would also be a good idea. Show us you put some effort into this.

Most patents I saw were targeting starches from grains or sugar cane stalks.
The source of the starch is not that important, especially for the non-enzyme methods. There are problems with those routes, H2SO4 gives some
condensation products, HCl can form chlorocarbons which are undesirable if the dextrose is to be used in foodstuffs.
generic enzyme hadrolysis
Some plant examples with high starch content are corn, potato, rice, sorghum, wheat, and cassava.

You need to learn how to use a search engine. For instance, Google with the term starch hydrolysis patent -cassava gets 192.000 hits, some
of which must be useful.

Alpha-amylase and gluco-amylase are whats needed to break down starch into glucose.
Good luck finding them cheap though.
Not all chemicals are bad. Without chemicals such as hydrogen and oxygen, for example, there would be no way to make water, a vital ingredient in
beer.

Another name for cassava is tapioca.
Used here for making (bad) Thai whiskey.

Just recently i was attempting to decompose starch in to dextrin. Perhaps one could first break down to dextrin and then glucose from there.

"tapioca is commonly plant?"
Exactly where do you live that you aren't familiar with cassava?
If I were in a bad mood, I'd have suggested that you spit into your starch to break it down into glucose, but I'm not.  In any case, I really suggest that you spend some time searching around before
asking us.

there are literally tens of thousands of documents related to what you want to do, sitting out there on the Internet. Some are basic research, some
are more detailed, some are just overviews.

If you can't even use a telephone directory to answer that question of yours, I really don't think your little project is going anywhere.

Put 'amylase' in the search box on the left.
That link is for Gert Strand, of Sweden. Main point of entry is:

Fashist, is this what you had in mind ? I've had the alpha-amylase enzyme for years.
It breaks up long starch(amylose) chains. I use barley malt to get the beta-amylase.
It breaks it even further into maltose(G-G).
IIRC, the amyloglucosidase, a gamma-amylase, breaks down other types of sugars to
glucose.
From opening of NCIS New Orleans - It goes a BOOM ! BOOM ! BOOM ! MUHAHAHAHAHAHAHA !
