This study aims to develop a puffer fish skin gelatin (PSG) film that contains Lam. leaf extract (ME) as a new biodegradable film. With the increase in ME concentration, the tensile strength and elongation at break of the PSG film increased, whereas the oxygen permeability and water vapor permeability decreased. In addition, the PSG film with ME exhibited antimicrobial activity against and antioxidant activity. To apply the ME-containing PSG film to food packaging, Gouda cheese was wrapped with the ME-containing PSG film. During storage, the cheese packaging with the ME-containing PSG film effectively inhibited the microbial growth and retarded the lipid oxidation of cheese compared with the control sample. Thus, the ME-containing PSG film can be used as an antimicrobial and antioxidative packaging material to improve the quality of food products.
本研究旨在开发一种含有月桂叶提取物(ME)的河豚鱼皮明胶(PSG)薄膜,作为一种新型可生物降解薄膜。随着ME浓度的增加,PSG薄膜的拉伸强度和断裂伸长率增加,而氧气透过率和水蒸气透过率降低。此外,含有ME的PSG薄膜具有抗微生物活性和抗氧化活性。为了将含ME的PSG薄膜应用于食品包装,用含ME的PSG薄膜包裹了高达干酪。在储存期间,与对照样品相比,用含ME的PSG薄膜包装的奶酪有效地抑制了微生物生长,并延缓了奶酪的脂质氧化。因此,含ME的PSG薄膜可用作抗微生物和抗氧化包装材料,以提高食品质量。
