AI Technical Summary
Existing petroleum-based polymer absorbent resin pads have problems such as poor environmental compatibility, risk of chemical compound migration, and limited functionality in the preservation of chilled meat, making it difficult to meet food safety requirements. In addition, natural plant essential oils are highly volatile and have poor stability, making it difficult to maintain their preservation effect for a long time.
Lemon seed oil is encapsulated with liposomes composed of soybean lecithin and cholesterol, and combined with sodium alginate and carrageenan to form a composite aerogel pad. The composite aerogel pad loaded with lemon seed oil liposomes is prepared by vacuum freeze-drying, so as to achieve slow release of essential oil and long-lasting antibacterial and antioxidant effects.
The prepared lemon seed oil-loaded liposome composite aerogel pad extends the shelf life of chilled meat by 3-5 days. It has excellent water absorption and long-lasting slow-release preservation effect. Moreover, the components are natural and safe. It can be completely degraded within 45 days without microplastic residue.
