In a groundbreaking study published in ‘Shipin gongye ke-ji’ (Food Industry Technology), researchers from Northeast Agricultural University in Harbin, China, have unveiled a novel method for enhancing the stability of soybean oil body complex emulsions using ultrasonic treatment. This innovation not only promises to improve the transport of fat-soluble bioactives like β-carotene but also holds significant implications for the food and energy sectors.
Lead author Zhenxiao Wang and his team have harnessed the power of ultrasonication to optimize the preparation of these emulsions, which are formed from soybean oil bodies. Their research reveals that applying ultrasonic waves at a power of 450 W for 10 minutes results in an emulsion with an average particle size of 1537 nm, characterized by round and evenly distributed droplets. Wang stated, “The ultrasound-induced cavitation effect enhances the physical forces within the emulsion, leading to a remarkable improvement in stability.”
What makes this study particularly relevant is its potential commercial application in the energy sector. As the demand for natural and sustainable food additives grows, the use of soybean oil bodies as emulsifiers can pave the way for more eco-friendly food processing methods. The findings indicate that the encapsulation rate of β-carotene reached an impressive 94.9% at optimal ultrasonic conditions, with a retention rate of 81.8% after 11 days of storage at room temperature. This high retention rate suggests that products using these emulsions could maintain their nutritional value longer, a key selling point for health-conscious consumers.
Moreover, the study highlights how ultrasonic treatment can inhibit the generation of oxidation products, enhancing the oxidative stability of the emulsions. This characteristic could lead to longer shelf lives for food products, reducing waste and contributing to more sustainable practices in the industry. “Our research provides valuable insights into the application of soybean oil bodies, not just as food additives but as carriers for bioactive substances,” Wang added.
The implications of these findings extend beyond food science. As industries seek to reduce their carbon footprints, the use of natural emulsifiers like those derived from soybean oil could become a cornerstone in developing more sustainable production processes. This aligns with global trends towards sustainability and could inspire further innovations in both food technology and energy efficiency.
