Snack products and processes for their manufacture are disclosed. The snack products provide a high concentration of protein, particularly soy protein, while maintaining an acceptable taste and texture. Additionally, there is a significant inhibition of the growth of microorganisms in the high protein snack products due to the high protein snack products having a low water activity. The high protein snack products comprise a textured soy protein product and a fruit or savory flavor flavoring agent and a semi-chewy or crisp texture.
