This study uses a standardised protocol to explore prototype marmalade production using hawthorn fruit puree and sea buckthorn pectin. Hawthorn fruit puree exhibited a rich nutritional profile, prompting sea buckthorn pectin incorporation to enhance gelling capacity. Physicochemical analysis confirmed pectin’s suitability. Evaluating pectin gelation, influenced by Ca2+, identified optimal calcium lactate ranges. Samples underwent organoleptic assessment, showing appealing sensory attributes enhanced by cavitation treatment. Analysis confirmed marmalade’s retention of micronutrients and high antioxidant activity. Structural assessment revealed distinct elastic-lamellar structures, elucidated through atomic force microscopy. This study offers valuable insights into marmalade production and quality attributes, suggesting a pathway for utilising natural ingredients in functional food formulations.
