6 Ways to Slow Staling in Baked Goods

Six ways to slow staling in baked goods with ingredients and your process.

Someday, your products will go stale. Recrystallization of the starch molecules, gluten cross-links and moisture re-distribution are the main causes. Thankfully, there are ways to at least keep this process at bay!

How to slow staling with ingredients 

  • Enzymes: alpha amylase, pullulanase, lipase, lipoxygenase, protease and other non-starch polysaccharide-modifying enzymes help decrease staling.
  • Surface Active Lipids:  DATEM, SSL, lecithin and monoglycerides all decrease it.
  • Other ingredients: Fat, wheat gluten, high protein flour, shortening, gums and sugar all help prohibit staleness by helping retain water in the bread and disrupt cross-links.

How to slow staling with your process 

  • Storage Temperatures: Keep them around 2°C (77°F) or -18°C (-0.4°F) and avoid temperatures above 4°C (39.2°F).
  • Moisture Migration: lose as little moisture as possible. It speeds up reactions responsible for staling.
  • Processing: keep baking temperatures low and loaf volume high.

How to measure staling

Before you know how much to adjust your formula and process to stop staling, it helps to know just how much your product stales, and how quickly it does it. Here are a few tests that can help:

  1. Rheological methods: Uniaxial compression and pasting properties
  2. Thermal analysis
  3. Infrared spectroscopy: Fourier transform infrared (FTIR), near infrared (NIR) reflectance, and nuclear magnetic resonance (NMR) spectroscopy
  4. X-ray crystallography
  5. Microscopy: Transmitted and polarized light, confocal laser scanning(CLSM) and electron
  6. Sensory/organoleptic tests

Dr. Lin Carson’s love affair with baking started over 25 years ago when she earned her BSc degree in Food Science & Technology at the Ohio State University. She went on to earn her MSc then PhD from the Department of Grain Science at Kansas State University. Seeing that technical information was not freely shared in the baking industry, Dr. Lin decided to launch BAKERpedia to cover this gap. Today, as the world’s only FREE and comprehensive online technical resource for the commercial baking industry, BAKERpedia is used by over half a million commercial bakers, ingredient sellers, equipment suppliers and baking entrepreneurs annually. You can catch Dr. Lin regularly on the BAKED In Science podcast solving baking problems. For more information on Dr. Lin, subscribe to her "Ask Dr. Lin" YouTube Channel, or follow her on LinkedIn.
