Abstract

In the present study, ethanolic extracts from the extract of unshelled seeds of Cannabis sativa L. were used to produce films in order not to generate additional waste, taking into view a circular economy. Combinations of apple pectin and citrus pectin in a ratio of 80:20 were used. Film samples containing 0.5, 1.0 and 2.5 [wt%] of the extract were extruded. Antimicrobial, mechanical and barrier properties of the obtained films were tested. Samples with 0.5 [wt%] showed a WVTR of 16.98 [g/m²d]. The water vapour barrier properties of the films decreased with an increase in the amount of extract used. As the amount of extract increased, the transparency of the films decreased linearly to 12.84 [%] (0.5 [wt%]), 4.90 [%] (1.0 [wt%]) and 4.99 [%] (2.5 [wt%]). It was observed that the brightness of the samples decreased with increasing concentration, due to the presence of higher levels of phenolic compounds. Tests carried out showed that the prepared films exhibited inhibitory activity against all micrograms tested. All prepared films had antibacterial activity against the Salmonella typhimurium strain. Similarly, in the case of L. monocytogenes.

以大麻籽提取物为媒介的创新型活性生物基食品包装材料，可减少食品浪费。

在本研究中，考虑到循环经济，从大麻（Cannabis sativa L.）去壳种子的提取物中提取乙醇萃取物用于生产薄膜，以避免产生额外的废物。苹果果胶和柑橘果胶的比例为 80:20。挤压出含有 0.5、1.0 和 2.5 [wt%] 提取物的薄膜样品。对所得薄膜的抗菌性、机械性和阻隔性进行了测试。含 0.5 [wt%] 的样品的水蒸气阻隔率为 16.98 [g/m2d]。薄膜的水蒸气阻隔性能随着提取物用量的增加而降低。随着萃取物用量的增加，薄膜的透明度直线下降，分别为 12.84 [%] （0.5 [重量%]）、4.90 [%] （1.0 [重量%]）和 4.99 [%] （2.5 [重量%]）。据观察，由于酚类化合物含量较高，样品的亮度随着浓度的增加而降低。测试表明，制备的薄膜对测试的所有微生物都具有抑制活性。所有制备的薄膜都对鼠伤寒沙门氏菌菌株具有抗菌活性。同样，对单核细胞增多性酵母菌（L. monocytogenes）也具有抗菌活性。

期刊介绍： Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields. Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication. The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
