DESCRIPTION:
BRIEF SUMMARY
This invention concerns a composition for use as a substitute for petrolatum and for surface treatment of confectionery, food products and surfaces which get in contact therewith, as well as for external treatment of animals and plants.
BACKGROUND OF THE INVENTION
Petrolatum Vaseline has been used for years in cosmetics and pharmacy for i.a. ointments and emulsions, because of the oil-binding, consistency-imparting and skin-refatting properties of the substance, which has also been used as a vehicle for skin active components.
Further, for many years it has been known to use surface treatment compositions in the manufacture of confectionery (e.g. liquorice, wine gum/jelly articles) and dried fruit (e.g. raisins, prunes, nuts) to give the products a shiny and glossy surface, to reduce the tendency of desiccation of the product as well as to prevent the individual product articles from sticking together.
It is also known to use paraffin oil and/or petrolatum for treating surfaces which get in direct contact with food products or food product ingredients, e.g. in the meat and bakery industries.
Furthermore, it is known to use mineral oil based products as a vehicle for bioactive substances and the like for application to animals and plants either directly or in the form of an emulsion.
Petrolatum is a mixture of predominantly saturated, solid and liquid hydrocarbons recovered from residues from distillation of mineral oil. Typically, the hydrocarbons consist of 5-20% n-paraffins as well as branched and cyclic, however, rarely aromatic components. Owing to this hetorogeneous composition petrolatum has a characteristic soft, amorphous structure over a wide temperature range.
Paraffin oil which is a mineral oil fraction, has been used for surface treatment of liquorice and jelly articles (e.g. wine gum), and here wax and/or petrolatum is generally added to increase the adhesion, the gloss and in particular the anti-sticking effect.
Paraffin oil has likewise been used for surface treatment of dried fruit (e.g. raisins), primarily as a gloss agent and a preservative, but also as an anti-sticking agent for raisins for industrial purposes (e.g. used for dragees, etc.). Advantageously, a wax type, typically beeswax, may additionally be added to raisins used in muesli products.
In recent years several countries have focused on limiting the use of paraffin oil and other mineral oil products in food products, cosmetics and pharmaceuticals because of health reasons.
So-called MCT oils (Medium Chain Triglycerides) and oxidation resistant glyceride oils, so-called high stability oils, have been used as a substitute for paraffin oil in surface treatment compositions for food products.
MCT oils are synthetic triglycerides made from glycerol and predominantly caprylic, captic and lauric acid in varying quantitative proportions. They are supplied i.a. under the trade name "Crodamol GTCC" by Croda Surfactants Ltd., England; under the trade name "Miglyol 810" by Huls AG, Marl, Germany; under the trade name "Neobee M-5" by Stepan Company Illinois U.S.A.; and under the trade name "Delios MCTs" by Henkel Corporation, USA.
For use in surface treatment compositions for food products the MCT oils have the following advantages: milk white, with visible crystals, which may cause deposition of dim crystalline spots on clear packages.
Known oxidation resistant oils, which are extensively used for surface treatment of raisins, are partly liquid fractions of hardened vegetable liquid oils, (cottonseed oil, soybean oil, palm oil, rapeseed oil). They are supplied under the trade name "Durkex 500" by Loders & Croklaan, Holland; under the trade name "Akorex" by Karlshams Oils and Fats AB, Sweden; and under the trade name "Coatex 01" by Aarhus Oliefabrik A/S, Denmark.
For surface treatment of raisins these oxidation resistant oils have the following advantages: surface treated raisins, which may result in a dull tinge on the raisins. of oil and sticking together and desiccation of the raisins.
