जब हम रोटी बनाते हैं, तो वह सिकते समय फूल जाती है। इसके पीछे एक वैज्ञानिक कारण होता है।
रोटी कार्बन डाइऑक्साइड गैस के कारण फूलती है।आटे को गूंथते समय उसमें थोड़ी हवा फंस जाती है और गर्मी मिलने पर यह गैस फैलने लगती है। साथ ही, आटे में मौजूद नमी गर्म होकर भाप (steam) में बदल जाती है, जो रोटी को अंदर से फुलाने में मदद करती है।
जब रोटी दोनों तरफ से सिकती है, तो बीच में भाप और गैस जमा होकर उसे गुब्बारे की तरह फुला देती है। यही कारण है कि अच्छी तरह से गूंथी और सही तरीके से सेंकी गई रोटी ज्यादा अच्छी तरह फूलती है।रोटी के फूलने की प्रक्रिया गर्मी, भाप और गैस के फैलाव का परिणाम होती है।
