Frequently Asked Questions (Technical)

Q: Is butternut squash flour heat‑stable for baking?
A: Yes. It maintains β‑carotene integrity at standard baking temperatures (175 – 200°C). For extended high‑temperature processing (>200°C, >20 min), we recommend adding a natural antioxidant (e.g., rosemary extract) or using our encapsulated grade.

Q: Can it replace wheat flour entirely in gluten‑free baking?
A: For best results, replace 20 – 30% of wheat flour. For 100% replacement, blend with other gluten‑free flours (rice, almond, tapioca) and add a binding agent (xanthan gum or psyllium husk).

Q: What is the fiber composition?
A: 35 – 40% total dietary fiber, of which 25 – 28% is soluble fiber — significantly higher than most gluten‑free flours (typically 5 – 15% total fiber).

Q: Does it contain any preservatives or additives?
A: No. Our butternut squash flour is 100% pure squash — zero additives, fillers, preservatives, or anti‑caking agents.

Q: Is organic certification available?
A: Yes. USDA Organic certified grade is standard. EU Organic certification is also available upon request.

Q: What is the flavor profile?
A: Naturally sweet, mild, and nutty — similar to roasted butternut squash. No bitter or off‑notes.

Q: Can you supply custom blends with other ingredients?
A: Yes. We regularly blend with rice flour, almond flour, coconut flour, oat flour, cassava flour, acerola (vitamin C), and astaxanthin.

Q: What is the global market outlook for butternut squash products?
A: The global butternut squash market was valued at approximately $2.5 – $2.8 billion in 2024 and is projected to reach $4.2 – $5.5 billion by 2034, growing at a CAGR of 4.1 – 5.3%. Key drivers include increasing consumer awareness of nutritional benefits, rising demand for plant‑based and gluten‑free foods, and the convenience of value‑added product forms.
