Product Insights
Fast Action Dried Yeast, sold in 8‑sachet packs by Sainsbury’s, is a dehydrated baker’s yeast used as a leavening agent in baking. It delivers very high protein (45.8 g per 100 g) with low fat and very low salt, while its sugar level (13.9 g per 100 g) is close to the average for similar products, but it is classified as ultra‑processed (NOVA 4) and does not carry a Nutri‑Score because it is considered a food additive. The formula is vegetarian and vegan‑friendly yet contains wheat‑derived ingredients (gluten) and several additives – calcium sulphate, sorbitan monostearate, ascorbic acid and alpha‑amylase – which may concern allergy‑ or clean‑label‑focused consumers.
