Twin Stick Sachets for Spices and Herbs



Twin Stick sachets for spices and herbs

Intorduction

Generally buyers will order subject to a pre-shipment sample approval. The sample should be fully representative of the shipment, and should show the producer name, date, sample contents, batch number and quantity represented. Sample bottles should not leak or be able to contaminate the sample. Plastic bottles are generally not suitable. Packing information on the container sizes and quantities of the shipment should also be sent. The sample should be couriered with individual bottles in plastic bags to avoid or isolate any leakage, and bubble-wrapped. Buyers' requirements may include the following:

Material safety data sheet examples can be found on some buyers.

Technical data sheet.

Pesticide residue analysis.

GMO free declaration.

Declaration of non-animal product derivatives.

Description of innovative idea

Exfoliating spices and herbs were packed in sachets of composite packaging consisting of polyethylene, aluminium and polyester layers stuck together by polyurethane adhesive, and they were kept in an oven at 40°C in order to accelerate the delamination process. The sachets were then delaminated and the resulting layers were analysed. A headspace solid-phase microextraction mass spectrometry method (HS-SPME-GC-MS) using a 75mm carboxen polydimethylsiloxane fibre was used to identify the compounds migrating from the exfoliating spices and herbs through the polyethylene layer to the aluminium interface and suspected to be responsible for packaging delamination (Atek, 2005, 707).

Several volatile compounds used in the food industry as perfumes, fixing agents and preservatives, such as menthol, dihydromyrcenol and 2-phenoxyethanol, were detected in the aluminium/polyester delaminated layer. The exfoliating spices and herbs were also analysed by HS-SPME-GC-MS. The proposal of loss of adhesion of the laminated material exposed to the exfoliating products revealed that the product with a higher concentration of 2-phenoxyethanol caused a faster decrease in adhesion strength, but the lower adhesion values were found in products with higher concentrations of menthol and dihydromyrcenol. The results obtained showed that the analytical method used was suitable for identifying volatile compounds that migrate through polyethylene to the inner layers of the packaging of exfoliating products, as well as for providing prior information on which products may be difficult to package in sachets.

Scope of proposal

Spices production is one of the most important sectors in the food industry. The large number and wide variety of new products in development, and the huge volume of capital invested in this field, are two important characteristics of this industry. Spices, herbs, etc are some examples of the large number of food products available on the market. This study analyses exfoliating creams due to their influence on the loss of packaging properties. These products are used to remove the upper layers of dead skin cells and usually have solid particles suspended in order to improve the exfoliating process.

They also contain chemical agents, generally organic compounds, which break the structures of the dead skin cells to enhance skin cleaning. These products are in a constant evolution, with the development of new formulations and ...
