what is the purpose of baking soda in this recipe – Falafel Burgers?

wondering what the ramifications of leaving it out would be … thanks!

Place onion, garlic, jalapeño and cilantro (or parsley) in a food processor and pulse until uniformly chopped. Add chickpeas, cumin, coriander, baking soda and salt. Process until well combined. Transfer to a medium bowl. Stir in breadcrumbs. Cover and refrigerate for 20 minutes. (This allows the breadcrumbs to absorb excess moisture.)
