I would guess that high sugar sauces, such as sweet and sour, would turn into a sticky, jam-like ooze when dried.

That said, I've added the same ingredients as I'd put into teriyaki: soy sauce, ginger, and garlic, substituting Splenda for sugar or honey, to "Asian" vegetable mixtures and dehydrated those successfully. Over-season the veggies and maybe cooked meat or fish, dehydrate, and add to rice or noodles on the trail when its time to rehydrate them.

Similarly, I've dehydrated shredded BBQ meats successfully.

Hope this helps.
