COMPLETE SPECIFICATION STANDARD PATENT TITLE OF INVENTION PETROSELINIC ACID AND ITS USE IN FOOD Name and Address of Applicant: Loders Croklaan B.V. of Zaandijkerweg 36 1521 AX Wormerveer, The Netherlands The following statement is a full description of this invention, including the best method of performing it known to me:- F 7476 (V) Petroselinic acid and its use in food Petroselinic acid is a well known compound that eg is present in coriander oil in relatively high amounts. Its use in food products is also disclosed in literature. EP 777971 eg discloses that fat compositions can be obtained from fats that have high contents of asymmetric monounsaturated fatty acids, such as petroselinic acid, ie PSA 79 wt%) and that have simultaneously low contents of 10 trans acids 5 The fat compositions obtained can be used as fat replacer with a number of benefits such as providing good textural properties to the food, while not raising the LDL-cholesterol levels in the blood serum. When considering example 5, in particular table 3 of this patent application one must conclude that good product performance is only obtained if the fat applied contains about 12 wt% PSA. Products based on fats without PSA perform badly (=control fat Fats with only small amounts PSA are still grainy, while using a fat with a high content of PSA (=fat 4 with about 64 wt% PSA via the coriander oil) has a poor overall appearance. Food products that are indicated are margarines, dressings, confections, spreads, frozen desserts, ice cream, mayonnaise, mustards, cheese, dip sauces, bread, biscuit, dairy products, frying oils, CBE's, candy, meat, egg products, nut products, vegetable or fruit products, toppings, creams, puddings, cookies, pastries, pies, crackers, cakes, bread rolls and ingredients or premixes herefore. As PSA is the active ingredient that provides the health benefits to the food product there is a big need to be able to use fats with high levels of PSA but that perform well when applied in food products. Ie the appearance of the food products should be good as well.

F 7476 (V) 2 Inflammation is a key problem in a number of disease states. Extensive scientific research has focused on identifying compounds that have anti-inflammatory activity.

So far the main treaments are synthetic compounds in the pharmaceutical area or complex mixtures of compounds, synthetic or natural. It is known that fish oils can be used to some extent as an anti-inflammatory. However, fish oils have the disadvantage of being very unstable and of 10 forming off tastes very easily. Therefore the use of products based on fish oils as anti-inflammatory *--compositions has not found wide commercial application within the public domain.

US 4 918 063 (1990) discloses that some specific inflammatory diseases such as peptic ulcer disease or inflammatory bowel disease can be prevented or treated with mixtures of saturated or unsaturated phospholipids and saturated or unsaturated triglycerides and/or sterols. The activity of these mixtures is attributed to the fact that these mixtures have the ability to increase or maintain its hydrophobic character by treating the luminal surface of the gastrointestinal tract. It is expressly disclosed that the use of unsaturated phospholipids per se does not work.

These compounds only can work in the presence of a triglyceride or sterol. This thus leads away from using unsaturated derivatives of fatty acids for the purposes mentioned in this document. No examples are given for the use of petroselinic acid or glycerides containing this. The only indication herefore can be found in a listing in table i.

The teaching laid down in the above US 063 is confirmed by F 7476 (V) 3 US 5 178 873, wherein a method for inhibiting phospholipase A2 activity is disclosed by using stearidionic acid or a C20:4 unsaturated fatty acid. In the Tables 2 and 3 it is demonstrated in a comparative example that petroselinic acid is not useful for this purpose.

Another well recognized consumer problem is formed by the aging of the skin. In recent years the demand for methods to improve the appearance of skin and, in particular, for 0 reducing or preventing the visible signs of wrinkled, aged and/or photodamaged skin has grown enormously. It is known in the art that the levels of collagen, a dermal structural protein and decorin, a structuring proteoglycan in skin are significantly reduced with aged and/or photodamaged skin (Lavker et al J.Inv.Derm.1979 73:79-66, Bernstein et al Lab. Invest. 1995 72:662-669). The reduction in these proteins is associated with a decrease in the tensile strength of the skin causing wrinkles and laxity.

Extensive research has focused on identifying actives that have anti-aging activity. One of the main current actives is retinoic acid, giving wrinkle effacement and dermal repair through boosting for example by collagen synthesis Griffiths et al. N. Eng. J. med. 1993 329:530-535).

According to GB 2 181 349 another solution was found in the use of triglycerides derived from long chain polyunsaturated fatty acids in cosmetic or dermatological compositions. These compositions are thus not edible in general because they also will contain non edible components. Moreover the triglycerides derived from these polyunsaturated fatty acids are unstable in particular with respect to oxygen stability F 7476 (V) 4 We studied whether we could find a natural component that could be used as anti-inflammatory agent without creating problems of side effects and not having the negative aspects from fish oils, and other known anti-inflammatory compositions.

We also studied whether we could find a natural component that could be used as anti-aging agent without creating problems of side effects and not having the negative aspects from the known anti-aging compositions.

We further studied whether we could find fat compositions that combine high PSA levels with a very good product 15 performance.

o 0* 0 The study on anti-inflammatory and antiaging activity resulted in our finding that petroselinic acid derivatives e(ie free fatty acid, short alkyl ester, short being Cl-C4, wax-esters, mono-di- or triglycerides) can be applied as .00. firstly anti-inflammatory agents that act on the formation 0 of metabolites from arachidonic acid (a recognised 00 precursor of inflammatory mediators), or that can reduce the formation of intracellular adhesion molecules, and thus contribute to the inflammatory response. Or secondly can be applied as an anti-aging agent that act by boosting the levels of two structural proteins in the dermis of the skin, collagen and decorin. Moreover we found novel fat compositions that combine high PSA levels with good product performance.

Therefore our invention concerns in the first instance the use of edible compositions containing petroselinic acid for F 7476 (V) the preparation of functional food compositions or food supplements, wherein the composition containing petroselinic acid is used as an anti-inflammatory component that inhibits the production of metabolites of arachidonic acid and/or reduces the formation of intracellular adhesion molecules.

Our invention further concerns the use of edible compositions containing petroselinic acid for the preparation of functional food compositions or food supplements, wherein the composition containing petroselinic acid is used as an anti-aging component that boosts decorin levels with a positive impact on skin conditions selected from the group consisting of wrinkling, sagging, photodamaged skin, dry skin, flaky skin and age .9 "T "spots.

Functional food compositions being defined as food compositions containing at least one component with a health benefit. Food supplements being defined as .compositions that are not used as food per se, but that are used as supplement to the daily food intake, in general in the form of encapsulated essential food ingredients.

These edible compositions containing petroselinic acid can be applied in many different forms, but we prefer to apply these compositions as a composition comprising 5-99.9 wt% of fat or fat blend.

The fats that can be used in the compositions containing the petroselinic acid derivative can be selected from the group consisting of: cocoa butter equivalents, palm oil or fractions thereof, palm kernel oil or fractions thereof, interesterified mixtures of above fats, hardened fats or F 7476 (V) 6 fractions thereof, liquid oils, selected from sunflower oil, high oleic sunflower oil, soybean oil, rape seed oil, cotton seed oil, safflower oil, high oleic safflower oil, maize oil, MCT oils, hardened liquid oils or fractions thereof and mixtures hereof.

These fats are nearly all natural fats (the exception being MCT oils which are synthetic fats based on medium chain fatty acids ie fatty acids with 6-12 carbon atoms).

The level of petroselinic acid in the compositions that we 10 can apply for our purposes can vary widely, however we prefer to apply petroselinic acid containing compositions that contain 2-80 wt%, preferably 5-40 wt% of petroselinic acid derivative (calculated as petroselinic acid).

As already indicated above we found that the petroselinic acid could be used in different forms. Very good results were obtained by using the petroselinic acid as free fatty Sacid, or in a form wherein it is bound to a glycerol backbone as in mono-di- or triglycerides. In this latter case the glycerides must contain at least one petroselinic acid moiety. Other forms are short alkyl esters of the petroselinic acid, short meaning having one to eight, preferably 1 to 4 carbon atoms. Also wax esters, ie long chain alcohol esters of petroselinic acid can be applied.

Of course also mixtures of above forms can be used.

We also found that the anti-inflammatory and antiaging effect of the petroselinic acid can be increased, even in a synergistic way by using the petroselinic acid derivative in combination with one or more anti-oxidants. Typical examples of useful anti-oxidants can be selected from the group consisting of natural or synthetic tocopherols, F 7476 (V) 7 natural polyphenols, in particular as present in tea extracts, BHT, BHA, free radical scavengers and enzymes with anti-oxidant properties. From these anti-oxidants we prefer the tocopherols and the polyphenols as present in tea extracts the most.

The petroselinic acid derivatives will structure the fats when applied in a fat surrounding. Therefore structured fats comprising the petroselinic acid composition and 0 wherein the fat has a level of saturated plus trans fatty acids of 25-75 wt% are also part of our invention.

S Part of the invention are also the blends of the petroselinic acid containing composition and 0.01-5 wt% of one or more anti-oxidants selected from the group consisting of: natural or synthetic tocopherols, natural polyphenols, in particular as present in tea extracts, BHT, BHA, free radical scavengers and enzymes with anti-oxidant properties.

Food products or food supplements containing these blends are also part of our invention. As food products all food products indicated in EP 777971 could be used.

A very useful form wherein the active petroselinic acid or derivative can be applied is an encapsulated composition, wherein the petroselinic acid is encapsulated in an edible encapsulating material. The encapsulating material is selected from the group consisting of: polysaccharides, sugars, fats, proteins and amino acids.

The encapsulating material is present in an amount of 5-95 wt% on basis of total encapsulated composition.

F 7476 (V) 8 These encapsulated forms are in general free flowing which makes the dosing of the food products or food supplements easier.

As a result of our study to find fat compositions that combine high PSA levels with very good product performance we found that fat compositions comprising asymmetric isomers from cis monounsaturated fatty acids, wherein the fat composition comprises 15-75 wt%, preferably 20-60 wt%, most preferably 30-60 wt% of asymmetric isomers from cis monounsaturated fatty acids preferably being petroselinic acid, 25-50 wt%, preferably 30-40 wt% of saturated fatty .".acids with 12-24 carbon atoms and 0-60 wt%, preferably 5-50 wt%, most preferably 15-45 wt% of isomers of other fatty acids with at least 18 carbon atoms, preferably having a cis 9 double bond, preferably being oleic acid, or linoleic acid, are very suitable for this purpose.

According to a preferred embodiment of this aspect of our invention these compositions comprise three components A, B ***and C, wherein: A has a content of asymmetric isomers from monounsaturated fatty acids of at least 20 wt%, preferably at least 40 wt%, most preferably at least 50 wt% B has a solid fat content, measured on a unstabelized fat by NMR, at 20 oC of at least 20, preferably at least most preferably at least 60 and C has a content of fatty acids with at least 18 C atoms and a cis 9 double bond of at least 40 wt%, while components A, B and C are present in amounts of: 15-90 wt% of A, preferably 20-75 wt%, most preferably 30-50 wt% F 7476 (V) 9 10-85 wt% of B, preferably 20-75 wt%, most preferably 30-60 wt% and 0-75 wt%, preferably 5-60 wt%, most preferably 15-50 wt% of

C.

Even more preferred compositions are obtained when the composition contains an additional fat component D in an amount of 5-60 wt%, which component D is an interesterified mixture of fats A and B in a weight ratio of 95:5-5:95.

1. 0 This then results in fat compositions, wherein the components A,B,C and D are present in amounts of: 5-75 wt% of A :15-60 wt% of B 5-75 wt% of fat C and 5-75 wt% of fat D.

In order to achieve the best mouth feel our fat compositions have a solid fat content unstabilised at 5 oC of 25-85, preferably 30-50 and at 35 oC of less than preferably less than 5. These solid fats contents are measured by NMR pulse techniques on a fat at measurement temperature. The value for the solid fat content depends on the pretreatment of the fat. Here the solid fat content is measured on a fat that is not stabilised. I.e. the fat was melted and kept at 60 oC for 30 min, after which the fat is cooled to 0 oC and kept hereon for another 30 min, whereupon the fat is heated to measurement temperature and the solid fat index is measured after keeping the fat at this temperature for at least 1 hour.

As a source for the PSA, coriander seed oil is very useful.

Coriander oil can contain up to about 80 wt% of PSA. Other F 7476 (V) fats relatively rich in PSA that can be applied as well are: parsley oil; and a number of fungal oils. PSA can also be obtained from carrots, fennel: chervil or caraway.

The content of cis 6 isomers of asymmetric monounsaturated fatty acids in fats having intermediate levels thereof can be increased by performing an enzymic conversion on a fat containing at least 5 wt% of cis 6 isomers of fatty acids of monounsaturated fatty acids and containing also cis 9 double bonds using an enzyme specific for cis 9 double 10 bonds and removing the products enriched in cis 9 double bonds. Enzymes suitable for this conversion are well known, an example being Geotrichum candidum.

Although the trans content of our fat compositions can be very low (ie 5 wt%) we can also make fat compositions with a very good performance if the trans content is 10-70 S"wt%. Herefore we can use partially hardened fats as fat component B or D. However low trans contents are in general preferred.

*Fat B that can be applied in making our fat compositions :can be selected from the group consisting of palm oil mid, palm oil stearin, cocoa butter and fully or partially hardened vegetable oils, like fully hardened bean oil, rape seed oil or cotton seed oil.

Fat C is suitably selected from the group consisting of sunflower oil, high oleic sunflower oil, olive oil, bean oil, safflower oil, rape seed oil, palm oil olein, olein fractions of vegetable oils, high oleic vegetable oils; corn oil; cotton seed oil.

F 7476 (V) 11 Part of our invention are also the food products with a fat phase containing or consisting of the fat composition according to our invention.

Examples of food products, wherein our novel fats can be applied are: margarines; spreads; ice-creams; confectionery products (in particular fillings), bakery products (cakes, puff-pastries, laminated products etc.), cream alternatives, mayonnaises, dressings, soups and sauces.

In these products the following benefits can be achieved: Higher SV in cakes and laminated products: higher patty heights in puff-pastries: better aerated batters for cake improved overrun and stand-up properties for cream alternatives, as well as shorter whip-times herefore and better melt-down and aeration preperties for confectionery fillings.

EXAMPLES

Methodology Anti-inflammatory cell assays It is emphasized that the anti-inflammatory effects were determined by in vitro tests wherein the production of intracellular adhesion molecules (=ICAM) and Prostaglandin E2 (=PGE2) production by the human skin fibroblasts is measured after being induced by 10 the inflammatory modulus phorbyl myristyl acetate (PMA).

Effects on basal PGE2 levels in keratinocytes are also S: measured. A reduction of the levels of ICAM and PGE2 is indicative for the anti-inflammatory effect.

Fibroblast cell assay Primary human foreskin fibroblasts at passage 2 (P2) were seeded into 96-well plates at 10000 cells/well and maintained for 24 hours in an atmosphere of 5% carbon dioxide in Dulbeccos Modified Eagles Medium I (DMEM) supplemented with 10% foetal calf serum.

Petroselinic acid was added to fresh cell media (DMEM, supplemented with 10% foetal calf serum) in 99 dimethylsulphoxide (DMSO, final concentration in triplicate and incubated for a further 24 hours. Phorbal myristate acetate (PMA) in ethanol/cell media (10nm) was added to the media and the cells incubated for a futher 24hours. PMA represents an external stressor which induces oxidative stress and inflammatory responses in cells. The fibroblasts media were then analysed as described below immediately or snap frozen in liquid nitrogen and stored at -70 C for future analysis. The cells were then counted to ensure no effect on cell number.

F 7476 (V) 13 Prostaglandin E2 (PGE2) assay Volumes of 50 Jl culture medium were taken for PGE2 assay after gently shaking the culture plate. PGE2 levels in the medium were determined with a Biotrak PGE2 immunoassay kit (Amersham, UK). The assay is based on the competition between unlabelled PGE2 in the sample and a fixed quantity of horseradish peroxidase labelled PGE2 for a limited amount of fixed PGE2 specific antibody. Concentrations of unlabelled sample PGE2 are determined according to a standard curve which was obtained 10 at the same time.

ICAM-1 assay Media were discarded and cells washed with Dulbecco PBS. To the washed cells, 150 4l 0.1% Triton X-100 (Sigma) was added for 3 minutes to extract ICAM from cell 15 membrane. The extracts were transferred to Eppendoff centrifuge tubes and centrifuged at 1000 g for 2 min to .o 0 remove cell debris. A volume of 100 p supernatant was used for ICAM assay. The soluble ICAM-1 was assessed with commercially available immunoenzymometric assay kit (R&D Systems). Concentrations of ICAM-1 in the samples were determined based on parallelly running standard curve.

Glutathione (GSH) depletion model The anti-inflammatory effects of petroselinic acid can also be shown using a glutathione (GSH) depletion model in fibroblasts. L- Buthionine sulfoximine (BSO, Sigma), a specific inhibitor of y-glutamylcysteine synthetase, was used to deplete intracellular GSH levels. This depletion model is based on the natural degradation of GSH while synthesis is inhibited.

BSO is added to the fibroblast cell media after 24 hours (0.25mM), this is predissolved in DMSO (DMSO, final F 7476 (V) 14 concentration In addition, where stated, the antioxidants Epigallocatechingallate (ECGC) and Quercetin were also added to the media after 24h. The former was dissolved directly in the media, quercetin was initially dissolved in ethanol, this was then diluted 500 fold into the media.

Keratinocyte PGE2 assay Keratinocytes were grown in 96 well plates to approximately 80% confluency in keratinocyte 10 growth medium (KGM) which was then replaced in with KGM without hydrocortisone for 24-48h. The cells were then incubated in the presence or absence of petroselinic acid for 24h. The medium was then removed and assayed for the pro-inflammatory PGE 2 content by Enzyme-linked immunoassay.

Keratinocyte SDS viability assay Keratinocytes were grown in 96 well plates to approximately 80% confluency in keratinocyte growth medium (KGM) which was then replaced in with KGM without hydrocortisone for 24-48h. The cells were then treated with a concentration of sodium do-decyl sulphate (SDS) which will produce cell viability of approximately 50% (2pg/ml). This is done in the presence or absence of petroselinic acid. After incubating for 24h the medium was removed and the cell viability determined by the Neutral Red method. Basically, the cells were incubated for 3h in KGM containing 25tg/ml neutral red after which the medium was removed and the cells were then extracted with lml of 1% acetic acid, 50% ethanol for The absorbance of the extract at 562nm was determined and the viability evaluated by reference to control wells which contained neither SDS or petroselinic acid. This methodology has shown that the keratinocyte toxicity of an F 7476 (V) irritant relates to the irritancy effect of the agent in vivo (Lawrence et al Toxicol. In Vitro 10, 331-340 1996).

Procedure For Measuring Procollagen-I and Decorin Synthesis In Human Dermal Fibroblasts Preparation of Dermal Fibroblast Conditioned Medium Primary human foreskin fibroblasts at passage 2 (P2) were seeded into 12-well plates at 10000 cells/cm 2 and 10 maintained for 24 hours in an atmosphere of 5% carbon dioxide and 4% oxygen in Dulbeccos Modified Eagles Medium (DMEM) supplemented with 10% foetal calf serum. After this *time the cells were washed with serum free DMEM and then incubated in fresh serum free DMEM for a further 60 hours.

15 The fibroblast monolayers were then washed again with serum free DMEM. Test reagents (petroselinic acid, EGCG and gallic acid) and vehicle controls were added to the cells in triplicate in a final volume of 0.4ml/well fresh serum free DMEM and incubated for a further 24 hours. This fibroblast conditioned medium was either analysed immediatedly or snap frozen in liquid nitrogen and stored at -70°C for future analysis. The cells were then counted and data from the dot-blot analysis subsequently standardised to cell number.

Dot Blot Assay for Decorin Protein in Dermal Fibroblast Conditioned Medium Samples of conditioned medium from dermal fibroblasts treated with vehicle (as a control) or test reagents were supplemented with 20mM dithiothreitol (1:10 dilution of 200mM stock solution) and 0.1% sodium dodecylsulphate (1:100 dilution of 10% stock solution), F 7476 (V) 16 mixed well and then incubated at 75C for 2 minutes. A standard for the assay was generated by serial dilution of neat fibroblast conditioned medium from fibroblasts seeded at 10000 cells/cm 2 in a 175cm 2 flask and maintained in serum free DMEM as described above. Assay samples were subsequently applied in triplicate to a prewetted sheet of Immobilon-P transfer membrane using the 96-well Bio-Dot Apparatus from Bio-Rad as described in the manufacturers guidelines. Approximately 200(l of medium was applied per 10 well. The medium was allowed to filter through the membrane under gravity (30 minutes) after which the membrane was washed twice with PBS (200pl). These PBS washes were allowed to filter through the membrane under gravity (2x15 minutes). The Bio-Dot apparatus was then 15 attached to a vacuum manifold and a third and final PBS wash carried out under suction. The apparatus was disassembled, the membrane removed and quickly cut as required before being placed in blocking buffer overnight at 4 0 C. Membranes prepared for decorin analysis were 20 blocked with 3% bovine serum albumin (BSA)/ 0.1% Tween 20 in phosphate buffered saline (PBS), whilst those for procollagen-I analysis were blocked with 5% (w/v) non fat dried milk powder/ 0.05% Tween 20 in PBS. The following day, the membranes were probed with 1:10000 dilution of primary antibodies to human decorin (rabbit polyclonal; Biogenesis) for 2 hours at room temperature.

The membranes were subsequently washed with TBS/ 0.05% Tween 20 (3 x 5 minutes) and then incubated with 1:1000 dilution of 12I-conjugated anti-rat or anti-rabbit F(ab')2 fragments (Amersham) as required for 1 hour at room temperature. Following this the Immobilon strips were F 7476 (V) 17 again washed with TBS/Tween 20 (3 x 5 minutes) before being allowed to dry in air at room temperature. The dried membranes were wrapped in cellophane and exposed to a Molecular Dynamics storage phosphor screen for 16-18 hours.

At the end of this time the exposed screen was scanned by a phosphorimager (Molecular Dynamics Phosphorimager SF) using ImageQuant TM software. Dot intensity was assessed by computer-assisted image analysis using the quantification tools in ImageQuant T M standardised to cell number and the effects of various test reagents on decorin and procollagen-I synthesis were determined relative to a vehicle treated control value of 100 arbitrary units.

Examples: 1. Anti-inflammatory effects in fibroblasts o Figure 1 demonstrates that challenging cells with an inflammatory stimulus such as PMA (Phorbol myristyl S 20 acetate) causes an increase in the inflammatory response as measured by prostaglandin E2 (PGE2) production.

Petroselinic acid, even at the levels of 0.1iM, dramatically reduces the inflammatory response as measured by PGE2 production. good anti-inflammatory activity.

Figure 2 demonstrates that petroselinic acid also decreases the production of Intracellular adhesion molecule (ICAM) in fibroblasts, which is another marker of inflammation. The reduction in ICAM occurs under both basal condition (control) and in cells stimulated with an inflammatory stimulus (in this case PMA).

2. Anti-inflammatory effects Synergy with antioxidants Figure 3 demonstrates the effects of BSO and PMA on inflammation as measured by the levels of ICAM.

Antioxidants decrease the ICAM response at a concentration of 10pM quercetin and ECGC. In this case petroselinic was F 7476 (V) added to the media at the lower level of 0.0lpM and had no effect. Yet in combination, petroselinic acid had a synergistic effect with the antioxidants tested.

The distance travelled is thus proportional to the hardness of the product.

The C-value can then be calculated from C=K.F/P 1 6 Where C= Yiel or C-value in (g/cm 2 F= Total weight of cone and sliding stem (g) P= Penetration depth (0.1mm) K= Fatctor for cone angle (400 5840) io Conductivity Conductivity is measured using a cell manufactured by URL Vlaardingen consisting of two parallel plates 1 cm apart, 15 approximately 3x2 cm in size. This is connected to a Philips PW 9526 digital conductivity meter. Conductivity can then be directly read off (in pSsm) after inserting the probe into the spread.

20 Collar Collar is measured by inserting a 5mm diameter steel rod to a depth of 10mm into the spread. The resulting raising of spread around the rod is graded on a scale of I to VI, with I meaning no raising of product around the rod. VI indicating large amounts of spread raised and cracking of the product around the rod.
