Description
技术领域 technical field
本发明涉及一种可食用膜材料及其制备方法，具体而言，涉及一种具有良好的抗油脂氧化性、抗菌性、阻隔性，且安全无毒可生物降解，能够用于食品内包装的可食用膜及其制备方法。The invention relates to an edible film material and a preparation method thereof, in particular to a film material with good oil oxidation resistance, antibacterial property and barrier property, which is safe, non-toxic and biodegradable, and can be used for food inner packaging Edible films and methods for their preparation.
背景技术 Background technique
可食用包装膜主要用于食品在运输、储存和货架存放过程中的保鲜，需要膜材料在安全无毒可生物降解的同时，还具有良好的阻气性、保香性、阻水汽渗透性、防水油渗透性、稳定性和较好的机械性能。Edible packaging film is mainly used to keep food fresh during transportation, storage and shelf storage. It is required that the film material not only be safe, non-toxic and biodegradable, but also have good gas barrier properties, fragrance retention properties, water vapor permeability resistance, Waterproof oil permeability, stability and good mechanical properties.
蛋白质具有来源丰富、可生物降解和安全无毒的特点，作为成膜底物广泛的应用于可食用包装膜。胶原是一种天然的蛋白质，广泛存在于动物的皮肤、骨、肌肉、跟腱、韧带和血管中，是结缔组织、软骨组织中重要的结构蛋白。胶原的分子量大，溶解性小，具有很好的成膜性。且胶原天然的三股螺旋结构以及自身紧密的纤维结构，使胶原材料显示出很强的韧性和强度，适用于制备膜材料。Protein is rich in sources, biodegradable, safe and non-toxic, and is widely used as a film-forming substrate in edible packaging films. Collagen is a natural protein that widely exists in animal skin, bone, muscle, Achilles tendon, ligament and blood vessel, and is an important structural protein in connective tissue and cartilage tissue. Collagen has a large molecular weight, low solubility, and good film-forming properties. Moreover, the natural triple helical structure of collagen and its own tight fiber structure make the collagen material show strong toughness and strength, which is suitable for the preparation of membrane materials.
单纯胶原膜的阻隔性能和机械性能均有限。蛋白质肽链之间的内聚力增加是提高膜阻隔性能的重要因素，可以通过氢键、静电作用以及共价键的形成来诱导蛋白质的稳定。研究中常通过蛋白质的化学交联、酶交联或物理处理来提高其阻隔性能以及机械性能。原花青素是一种在自然界中广泛存在的植物多酚，具有较强的抑菌、抗氧化和抗辐射能力，主要应用于食品、饮料、保健品及化妆品领域。原花青素分子中含有较多的酚羟基、醇羟基以及醚基，易与胶原上的羟基、氨基和羧基形成氢键，从而产生交联，提高胶原膜的阻隔性能和机械性能。因此，原花青素是一种有效的安全无毒的胶原交联剂。Pure collagen membranes have limited barrier and mechanical properties. The increase of cohesion between protein peptide chains is an important factor to improve membrane barrier properties, which can induce protein stabilization through hydrogen bonding, electrostatic interaction and the formation of covalent bonds. In research, chemical cross-linking, enzymatic cross-linking or physical treatment of proteins are often used to improve their barrier properties and mechanical properties. Proanthocyanidins are plant polyphenols that widely exist in nature and have strong antibacterial, anti-oxidation and anti-radiation capabilities. They are mainly used in food, beverages, health products and cosmetics. The proanthocyanidin molecule contains more phenolic hydroxyl groups, alcoholic hydroxyl groups and ether groups, which are easy to form hydrogen bonds with the hydroxyl groups, amino groups and carboxyl groups on the collagen, resulting in crosslinking and improving the barrier properties and mechanical properties of the collagen film. Therefore, proanthocyanidins are an effective, safe and non-toxic collagen cross-linking agent.
目前，已经有一些专利对胶原基可食用膜进行了公开。如CN101341977就公开了一种含有鱼皮胶原蛋白的可食用膜及其生产方法。CN1547434、CN1154797、CN1337179、CN1228922等专利对以胶原为主要原料制作肠衣的方法进行了公开。CN1723803公开了一种含有茶多酚和胶原蛋白的水晶肴肉用天然成膜保鲜剂，但只是将茶多酚作为保鲜剂的一种添加剂使用，并没有作为主要成分使用，并且其中采用的不是三股螺旋结构保持完好的胶原。这些可食用膜的机械性能、溶胀性能、阻隔性能和抗油脂氧化能力还有待改进，且以具有良好的抗氧化能力的原花青素交联胶原为基质的可食用膜还没有文献和专利报道。At present, some patents have disclosed collagen-based edible films. Just disclose a kind of edible film containing fish skin collagen and production method thereof as CN101341977. Patents such as CN1547434, CN1154797, CN1337179, and CN1228922 disclose methods for making casings with collagen as the main raw material. CN1723803 discloses a natural film-forming preservative for crystal meat meat containing tea polyphenols and collagen, but only uses tea polyphenols as an additive of the preservative, and does not use it as the main component, and what is used is not The triple helix structure keeps the collagen intact. The mechanical properties, swelling properties, barrier properties and oil oxidation resistance of these edible films need to be improved, and there are no literature and patent reports on edible films based on proanthocyanidin cross-linked collagen with good antioxidant capacity.
本发明提供了一种原花青素交联胶原为基质的可食用膜及其制备方法。该可食用膜是一种安全无毒可生物降解的天然保鲜膜，具有良好的抗油脂氧化性、抗菌性和阻隔性能，而且制备方法简单，利润空间大。另外，该可食用膜使用范围较广，可以应用于油脂类食品、冷冻食品、药物冲剂和方便食品的内包装，具有很好的市场应用前景。The invention provides an edible film with proanthocyanidin cross-linked collagen as a matrix and a preparation method thereof.
