Impact of Hemp Flour on the Nutritional, Sensory and Functional Characteristics of Wheat and Whole Wheat Muffins

“The growing consumer demand for plant-based, protein- and fiber-enriched foods has encouraged the incorporation of novel functional ingredients into bakery products.

Hemp flour (HF), obtained from cold-pressed hemp seeds, represents a sustainable ingredient rich in proteins, dietary fibers, lipids, and bioactive compounds, making it suitable for nutritional fortification.

This study investigated the impact of HF addition (5-40%) on the quality of muffins prepared with wheat flour (WF) and whole wheat flour (WWF).

An initial hedonic sensory evaluation identified 5-20% HF as the most acceptable substitution range, which was then subjected to detailed physicochemical, sensory, textural, colorimetric, and microbiological analyses.

Incorporation of HF significantly increased protein (up to +44%), fiber (up to +172%), and ash (up to +76%) contents, while decreasing moisture (-39%). Both WF and WWF muffins darkened with HF incorporation, with a greater lightness reduction in WF. Texture changes (increased firmness and gumminess) were more pronounced in WF muffins. Sensory analysis revealed that WF muffins were best accepted at 10-15% HF, whereas WWF muffins maintained good acceptability up to 20% HF, indicating better integration of HF in the whole grain matrix. All samples complied with microbiological safety requirements.

Overall, the optimal substitution level was 10-15% HF in WF muffins and 20% HF in WWF muffins, demonstrating that HF can enhance the nutritional profile of muffins while maintaining acceptable technological and sensory properties in a matrix-dependent manner.”

“In conclusion, HF offers clear advantages as a sustainable, plant-based ingredient for functional food development. It improves the protein, fiber, and mineral content of muffins, while the type of base flour plays a decisive role in determining texture, sensory quality, and overall acceptability. Future research should focus on optimizing formulations to achieve a balance between nutritional enhancement and sensory appeal, with particular attention paid to moisture retention and improving the palatability of higher HF levels in WF-based products.”
