Definitions

  • the present invention relates to a drinking straw, and in particular to a drinking straw with reduced environmental impact.
  • Plastics are an increasing global concern. In particular, plastics are a major source of marine litter that can adversely affect wildlife, wildlife habitat and humans. Living organisms, particularly marine animals, are susceptible to ingesting plastic waste or becoming entangled in plastic objects. The leaching of chemicals from plastics can also interfere with both human and animal physiology.
  • Single-use plastics such as bags, bottles and drinking straws are a particular environmental concern owing to their disposable nature. Governments are beginning to respond, such as by imposing levies and bans on plastic bags and introducing deposit return schemes on plastic bottles. Governments and companies are also looking to ban single-use plastic drinking straws.
  • the present invention provides a drinking straw composed of dried pasta and an edible wax.
  • the drinking straw of the present invention is biodegradable, resulting in minimal environmental impact.
  • the drinking straw of the present invention is an organic tube that breaks down in a non-harmful and non-toxic way, meaning that it is safe if it were to come into contact with wildlife and marine life in particular.
  • the combination of dried pasta and an edible wax component increases the durability of the drinking straw of the present invention and lengthens the amount of time that the straw can be used in a drink. This approach reduces the liquid absorption rate of the drinking straw of the present invention, slowing down the rate at which the straw becomes less structurally stable during use.
  • the present invention also provides a method of manufacturing a dried pasta drinking straw of the present invention comprising: (i) mixing pasta ingredients and an edible wax to form a dough; (ii) extruding the dough to form a tube; (iii) cutting the tube to a length to form a straw precursor; and (iv) drying the straw precursor until the straw contains 5-15% by weight of water, based on the total weight of the straw.
  • the pasta ingredients and the edible wax of the drinking straw of the present invention are renewable resources, further reducing the environmental impact. The use of renewable resources in the method of manufacturing the drinking straw of the present invention also ensures sustainability.

  • the drinking straw 10 comprises dried pasta and an edible wax. That is, the body 12 of the drinking straw 10 comprises dried pasta and an edible wax.
  • Pasta is a dough made from flour mixed with water or eggs and formed into sheets or various shapes. Pasta may be divided into two broad categories, dried ⁇ pasta secca) and fresh ⁇ pasta fresca). Typically, dried pasta is made with water, whilst fresh pasta is made with eggs.
  • the drinking straw 10 comprises dried pasta.
  • the dried pasta drinking straw 10 comprises flour and water.
  • Flour in this context refers to ground grains.
  • the dried pasta drinking straw 10 comprises flour selected from durum wheat, rice, maize, barley and buckwheat, chickpea, lentil or combinations thereof.
  • the dried pasta drinking straw 10 comprises durum wheat.
  • Durum wheat may be in the form of durum wheat flour and/or semolina, depending on how the durum wheat has been milled.
  • Durum wheat flour is durum wheat which has been ground until a powder.
  • durum wheat flour has a particle size of less than 130 pm.
  • Semolina means“semi-milled” and is a coarser flour than durum wheat flour.
  • semolina has a particle size of 130-550 pm.
  • the dried pasta drinking straw 10 comprises durum wheat flour and/or semolina.
  • the dried pasta drinking straw 10 comprises durum wheat flour.
  • the dried pasta drinking straw 10 comprises durum wheat flour and semolina.
  • Dried means that some water has been removed from the pasta drinking straw 10.
  • the dough typically contains 20-35% of water by weight, based on the total weight of the dough.
  • the water content is typically 5-15% by weight, based on the total weight of the pasta.
  • the dried pasta drinking straw 10 comprises 5-15% by weight of water, based on the total weight of the straw. This is a balance between the straw being not too dry that it is brittle and prone to breaking and not too wet that it does not hold its shape.
  • the dried pasta drinking straw is hard and not flexible meaning that it is durable.
  • the dried pasta drinking straw 10 comprises an edible wax.
  • the wax is edible in that it is non-harmful if ingested.
  • the purpose of the edible wax is to increase the durability of the drinking straw of the present invention and lengthen the amount of time that the straw can be used in a drink.
  • the dried pasta drinking straw 10 can be used for a longer amount of time in a drink, without getting soggy, than a piece of dried pasta.
  • a wax is an organic compound that is a lipophilic, malleable solid at 20°C.
  • the lipophilic nature of waxes means that they tend to be insoluble in water making them suitable for use in drinking straws, since drinking straws are typically used in water-based drinks.
  • Any edible wax is suitable.
  • the edible nature of the wax ensures that the dried pasta drinking straw remains biodegradable, minimising the impact on wildlife, wildlife habitat and humans.
  • Edible waxes are also renewable resources and so the pasta drinking straws of the present invention are sustainable.
  • the edible wax may be present as a coating on the body 12 of the dried pasta drinking straw 10.
  • the coating may be present on the interior and/or the exterior of the body 12 of the dried pasta drinking straw 10.

  • the edible wax is present as a coating on the exterior of the body 12 of the dried pasta drinking straw 10.
  • the edible wax is present as a coating on the interior and the exterior of the body 12 of the pasta drinking straw 10.
  • the presence of the edible wax as a coating acts as a water-repelling layer and prevents water from coming into contact with the dried pasta.
  • the edible wax may be present throughout the body 12 of the dried pasta drinking straw 10.
  • the dried pasta drinking straw 10 is a homogenous mixture of pasta ingredients and the edible wax.
  • the edible wax is present throughout the body 12 of the dried pasta drinking straw 10.
  • the pasta drinking straw 10 is particularly durable if the edible wax is present throughout the body 12 as the whole of the body 12 is reinforced with the edible wax.
  • the edible wax is present in 3-30% by weight, based on the total weight of the straw. More preferably, the edible wax is present in 5-25% by weight, and most preferably 8-20% by weight, based on the total weight of the straw. This ensures efficient waterproofing of the dried pasta drinking straw 10.
  • the edible wax of the dried pasta drinking straw 10 has a minimum melting point of 35°C. More preferably, the edible wax of the dried pasta drinking straw 10 has a minimum melting point of 40°C and most preferably, a minimum melting point of 45°C. In this way, the dried pasta drinking straw 10 is suitable for use in any cold drink.
  • the edible wax of the dried pasta drinking straw 10 may also have a higher minimum melting point so that the drinking straw is suitable for use in hot and cold drinks.
  • the edible wax of the dried pasta drinking straw 10 has a minimum melting point of 50°C, more preferably a minimum melting point of 60°C, and most preferably a minimum melting point of 70°C.

These waxes are all commercially available. Carnauba wax is particularly preferred. Carnauba wax has a relatively high melting point of 82-86°C and so the presence of carnauba wax means that the drinking straw is also suitable for use in hot drinks such as those having a temperature of up to 70°C. An example of a commercially available carnauba wax is carnauba wax having E number E903.
