BIODEGRADABLE PACKAGING INCORPORATING MALT BAGASSE: CONSUMER PERCEPTIONS AND ACCEPTANCE

Introduction: Biodegradable packaging from agro-industrial waste has been used as a sustainable alternative to plastic packaging, contributing to the reduction of non-biodegradable solid waste. However, the application of this packaging in food systems remains challenging, and limited research has addressed consumer acceptance. Objective: This study aimed to characterize the consumer profile, perceptions, and acceptance of biodegradable packaging produced by malt bagasse, an agro-industrial by-product of beer production. Methodology: A sociodemographic and consumption habits questionnaire about biodegradable packaging was applied personally to 100 participants. Subsequently, participants evaluated acceptance, using a nine-point hedonic scale for two types of biodegradable packaging, one of which was produced with malt bagasse, and purchase intention. Results: Most participants (78%) were young adults aged 18 to 34 years, with a high education level (52% ongoing or completed college). Regarding the packaging, 85% reported previous experience purchasing products with biodegradable packaging, generally with positive perceptions. Concern about the environment (74%) and a preference for sustainable products (16%) were the main reasons for choosing biodegradable packaging products. In relation to packaging attributes, biodegradability (62%) and resistance (89%) were considered highly important, whereas appearance (40%), color (37%), and texture (31%) were of secondary importance. Regarding acceptance and purchase intention, both biodegradable packaging showed positive overall liking (7.67 and 7.83), appearance (7.40 and 7.63), color (7.39 and 7.43), and texture (7.31 and 7.64). Additionally, 66% of participants indicated purchase intention. Although 81% reported willingness to pay more for biodegradable packaging, price sensitivity was observed, with 65% accepting up to a 5% price increase. The main products cited that may be packaged with these packages are hygiene and beauty products (78%) and fresh produce (74%). Conclusion: Biodegradable packaging incorporating malt bagasse represents a commercially viable alternative; however, consumer acceptance remains influenced by price sensitivity.
