Description

DESCRIPTION OF THE INVENTION

[0016] There is a continuing need for healthier fat spreads having reduced saturated fatty acids levels (SAFA), while the fat spreads can still maintain acceptable structure, texture, appearance and organoleptic properties over several months of storage. There also remains a need for healthier fat spreads having improved crystallization behaviour in order to facilitate the processing and the handling of fat spreads, particularly being quick crystallizing and having a high temperature onset of crystallization.

[0017] According to the present invention, there is provided a fat spread product comprising: [0018] at least 5% by weight of water; [0019] and from 10% to 95% by weight of a fat composition, wherein the fat composition comprises: [0020] from 10% to 100% by weight of an intraesterified fat or an interesterified fat blend comprising HSHO sunflower oil or a fraction derived from HSHO sunflower oil; [0021] at most 85% by weight of one liquid oil or liquid oil mixture; and [0022] at most 5% by weight of at least one fat soluble additive.

[0023] The fat spread of this invention has been found to be particularly healthy and surprisingly useful as table spread or for bakery applications. Fat spreads according to the invention provide not only particularly low palmitic acid and saturated acids level but also outstandingly favourable physical and organoleptic properties. In particular, the fat spread according to the invention provides good shelf life performance and crystallization properties.

[0024] In the context of the present invention: [0025] the term “fat spread” refers to any product in the form of a solid, malleable emulsion, principally of the water-in-oil type, derived from solid and/or liquid vegetable and/or animal fats suitable for human consumption, with a milk-fat content which does not exceed 3% of the fat content. Preferably, “fat spread” designates margarine, three-quarter-fat margarine, half-fat margarine, table spread or fat spread X % as defined in Appendix to Annex XV of EC Regulation 1234/2007; [0026] the term “fat” refers to glyceride fats and oils containing fatty acid acyl groups and does not imply any particular melting point. The term “oil” is used synonymously with “fat”; [0027] the term “intraesterified fat” refers to a fat in which fatty acids positions in triglyceride molecules are changed by a chemical or enzymatic process to modify triacylglycerols chemical, physical and/or nutritional properties. Intraesterification is conducted on a single fat; [0028] the term “interesterified fat blend” refers to a fat blend in which fatty acids positions in triglyceride molecules are changed by a chemical or enzymatic process to modify triacylglycerols chemical, physical and/or nutritional properties. Interesterification is conducted on a mixture of different fats or different fractions of fats; [0029] the term “liquid oil” refers to any single edible oil being in a liquid state at room temperature; [0030] the term “fat soluble additive” refers to minor fat soluble components that are added to fat blend and have functional, taste or nutritional effect in final fat spread.

Percentages of fatty acids in compositions referred to herein include acyl groups in tri-, di- and mono-glycerides present in the glycerides and are based on the total weight of C8 to C24 fatty acids. The fatty acid profile (i.e., composition) may be determined, for example, by fatty acid methyl ester analysis (FAME) using gas chromatography according to ISO 12966-2 and ISO 12966-4; the term “saturated fatty acid” (SAFA) and “saturated fat” both refer to a saturated acid containing from to 8 to 24 carbon atoms and having no double bonds between the individual carbon atoms of the fatty acid chain (i.e. the chain of carbon atoms is fully “saturated” with hydrogen atoms); [0032] the term “fraction derived from HSHO sunflower oil” refers to an oil or fat obtained from HSHO sunflower oil by one or more steps of dry or wet fractionation, which are well known techniques in the art. [0033] the term “TAG” designates triacylglycerol molecules, with a glycerol backbone and 3 fatty acids esterified to it. TAGs are named by three letters representing the fatty acids that are esterified on it at the different 3 positions of the glycerol molecule, said fatty acids being saturated (“S”) or unsaturated (“U”); [0034] “S” designates saturated fatty acids such as palmitic, stearic, arachidic and behenic acids; [0035] “U” designates unsaturated fatty acids such as oleic, linoleic and linolenic acids; [0036] “S55” designates trisaturated TAG, calculated from detailed TAG species results; [0037] “UUU” designates triunsaturated TAG, calculated from detailed TAG species results; [0038] “SUU” designates diunsaturated TAG, calculated from detailed TAG species results; [0039] “SUS” designates disaturated TAG, calculated from detailed TAG species results; [0040] amounts of triglycerides specified herein are percentages by weight based on total triglycerides present in the fat composition.

The notation A2B includes both AAB and ABA, and AB2 includes both ABB and BAB. Triglyceride content may be determined for example by GC. When referring to triglyceride, “P”, “St”, “O”, “L”, “Ln”, “A” and “B” respectively refer to palmitic, stearic, oleic, linoleic, linolenic, arachidic and behenic acids, respectively. Each GC peak includes triglycerides having the same fatty acids in different positions e.g., POSt is in the same signal peak as PStO; [0041] “SFC” designates Solid Fat Content measured by NMR (nuclear magnetic resonance) as the percentage mass fraction of fat in the solid state according to the ISO 8292-1:2008 method for non-stabilised fats; [0042] the term “at most ‘X’%” refers to a range of from 0% to ‘X’%; and [0043] unless otherwise specified, all % values are weight %.

EXAMPLES

Example 1—High Stearic Sunflower Oil and Enzymatic Intraesterified High Stearic Sunflower Oil

[0077] High Stearic Sunflower Oil (HSHO) can be obtained from high stearic sunflower seeds using standard oil pressing, refining and deodorization process. Deodorized HSHO oil can be used as ingredients as such for fat spreads and as raw material for preparing of intraesterified EIE HSHO (by enzymatic intraesterification) which can be also used as ingredient for fat spreads.

[0078] Enzymatic intraesterification of high stearic sunflower oil (EIE HSHO) was conducted following the protocol reported in Table 1 below.

[0079] As an alternative starting material for interesterification, fractions of HSHO sunflower oil and mixtures thereof can also be used to obtain comparable properties. In particular, stearins from HSHO sunflower oil are useful. Examples of suitable methods for wet and dry fractionation of HSHO sunflower oil are given in Bootello M A et al., Food Chem. 2015 Apr. 1; 172:710-7.

Example 2—Process for Preparing a Fat Spread Composition

[0080] First, a fat phase made of all fat soluble ingredients and a water phase made of all water soluble ingredients including are prepared.

[0081] Fat phase and water phase are heated up to 70° C. and emulsion is formed by adding water phase to fat phase under constant stirring.

[0082] Emulsion is crystallized in standard pilot scale margarine process using a Gerstenberg & Agger pilot perfector.

[0083] Finally, the products were packed in plastic tubs and stored at both 5° C. and 10° C.

Example 5: Solid Fat Content of the Fat Composition in Fat Spreads A, C, F, H and I

[0088] Solid fat content (%) of the fat compositions in fat spreads A and C, comparative fat spreads F, H and I, classical butter and tub margarine is reported in the Table 5 below. Solid fat content (%) is determined by NMR on unstabilised fat at 10, 20, 30, 35 and 40° C. (ISO 8292-1).

TABLE-US-00005 TABLE 5 Solid fat contents SFC (%) Sample 10° C. 20° C. 30° C. 35° C. 40° C. Comparative 1.6 0.2 0.4 0.3 0.3 fat spreads F, H, I Fat spreads: A, C 4.5 2.7 1.6 0.8 0.6 Butter 45 20 7 1 0 Tub margarine 21 12 5 3 2 fat blend (standard with 35% palm based hardstock and 65% liquid oil)

[0089] As evidenced by Table 5, fat spreads of the invention contain very low levels of solid fat at standard measurement temperatures 10° C. to 40° C. compared to standard butter and tub margarine fat spread.

[0090] Solid fat content measurement is standard analytics when evaluating fat blends suitability for spreads. SFC results <5% at 10° C. and <3% at 20° C. confirm existence of a significant difference between fat spreads A and C according to the invention and ‘Tub margarine bat blend’. A skilled artisan would not have considered fat spreads A and C according to the invention as suitable for preparing fat spreads without addition of hardstock in order to obtain the desired structure.

[0091] However, it is also believed that the structure and the texture of fat spreads could not be maintained properly when they have solid fat content lower than 2% at 10° C. and lower than 1% at 20° C., such as comparative fat spreads F, H and I.

Example 6: Triglyceride Composition of Fat Composition in Fat Spreads

[0092] The composition of TAG species was analyzed by gas chromatography of an Agilent 7890 gas chromatograph endowed with a 30 m. Quadrex aluminium-clad bonded methyl 65% phenyl silicone capillary column, 0.25 mm ID., 0.1 micron film thickness, using hydrogen as the carrier gas and FID detector according to Fernandez-Moya et al. J. Agr. Food Chem. 2000, 48:764-769. TAG classes (SSS, SUS, SUU, UUU) were calculated from detailed TAG species results. Each GC peak includes triglycerides having the same fatty acids in different positions e.g., POSt is in the same signal peak as PStO.

[0097] As shown in this FIGURE, Sample E—‘HSHO part’ (Blend of EIE HSHO and HSHO without rapeseed oil and fat soluble additives) and Sample E—‘Total fat blend’ (blend of EIE HSHO, HSHO and rapeseed oil but without fat soluble additives) begin to crystallize at higher temperatures than non-intraesterified fat (HSHO).

[0098] Sample E crystallization curves exhibit intermediate onsets of crystallization compared to HSHO (4.06° C.) and EIE HSHO (14.63° C.). The addition of liquid oil in “Sample E-Total fat blend” slightly reduces the onset of crystallization (8.86° C.), but it is still higher than HSHO oil.

[0099] Therefore, the fat spread E according to the invention has improved crystallization behaviour with a high temperature onset. This crystallization behaviour indicates a good processability and stable behaviour.

Example 8: Sensory Evaluation of Fat Spread a to J

[0100] Spreadability, emulsion stability and melting behaviour of fat spreads A to E and comparative fat spreads F to J were evaluated by sensory evaluation and compared to commercial fat spreads with same fat content, i.e. 40%, 60% and 80% fat respectively.

[0101] Sensory experts trained to evaluate such characteristics of fat spreads were asked to make this comparison using agreed scoring of good product.

[0102] Fresh samples fat spreads A to E and comparative fat spreads F to J have scoring in sensory evaluation that is comparable to products available on the market. Both fat spreads A to E and comparative fat spreads F to J have in particular smooth spreadability and no emulsion breakage is observed. Fat spreads A to E and comparative fat spreads F to J have also melting behaviour comparable to commercial samples with same total fat content.

[0103] During shelf life (being 4 to 6 months), it appeared that sensory evaluation results became unacceptable and unsatisfactory for comparative fat spreads F to J. These fat spreads lost the proper texture and became ‘sandy’. Their structure was not acceptable anymore at the end of shelf life. However, fat spreads A to E according to the invention showed still the good structure, texture, appearance and organoleptic properties.

[0104] These results combined with the results reported in Table 4 evidence that, despite fatty acid composition is the same, fat spreads A to E according to the invention are particularly stable in long term shelf life test comparing to comparative fat spreads F to J.

[0105] Finally, the taste of fat spreads A to E (fresh and at the end of shelf life) was evaluated and considered as comparable to commercial products with the same flavour affecting ingredients, in particular salt content and flavours.

Example 9: Fatty Acid Composition of Fat Spreads a to E and Comparative Fat Spreads F to J and Effect on Cholesterol Level

[0106] The effect on cholesterol level of fat spread compositions A to E and comparative fat spreads F to J has been calculated in light of the fatty acid compositions reported in Table 4. As cholesterol level effect results from fatty acid composition, it does not make difference between processing method of oils, thus HSHO and EIE HSHO oil results in same effect on cholesterol levels.

Method of Calculation

[0107] Effect of high stearic sunflower oil as well as some comparison fats/fat blends on the cholesterol level has been calculated using the factors reported by European Food Safety Administration (EFSA) (Estimated effects for the change in serum lipids and lipoproteins for a group of subjects when one percent of energy in the diet from carbohydrates is replaced isocalorically by a particular fatty acid) of the Opinion of the Scientific Panel on Dietetic Products, Nutrition and Allergies on a request from the Commission related to the presence of trans fatty acids in foods and the effect on human health of the consumption of trans fatty acids, EFSA Journal (2004), 81, 1-49.

[0108] According to this method, the cholesterol lowering effect of a fat blend can be calculated using the following formula:

[0109] Total cholesterol (TC) mmol/L change=+0.031*trans-monounsaturated fatty acids+0.069*lauric acid+0.059*myristic acid+0.041*palmitic acid−0.01*stearic acid−0.006*cis-monounsaturated fatty acids−0.021*cis polyunsaturated fatty acids. LDL mmol/L change=+0.040*trans-monounsaturated fatty acids+0.052*lauric acid+0.048*myristic acid+0.039*palmitic acid−0.004*stearic acid−0.009*cis-monounsaturated fatty acids−0.019*cis polyunsaturated fatty acids.

Results

[0110] Cholesterol lowering effect has been calculated based on a 100% fat which represents cholesterol lowering effect of fat or bat blend. This effect can be calculated also for fat blends of existing products, like butter fat, giving opportunity to compare different fats/fat blends effect on cholesterol levels.

[0111] The obtained calculated results are reported in the Table 7 below.

TABLE-US-00007 TABLE 7 Cholesterol effect of fat spreads fat blend Saturated fat % of total fatty TC change LDL change Sample acid composition (mmol/L) (mmol/L) Fat blend of fat spreads 25.9 −0.46 −0.56 A, C, F, H, >I Fat blend of fat spreads 23.8 −0.50 −0.61 B, D, E, G, J Butter fat 68.8 1.82 1.61 Fat blend from Vita 22.4 −0.36 −0.44 Hjertego 70%, commercial margarine with low saturated fat content Rapeseed oil 8.10 −0.79 −0.91

[0112] The calculated cholesterol lowering effect of fats spreads according to the present invention is more important than the cholesterol lowering effect of commercial margarine (Vita Hjertego 70%) containing less saturated fat. This indicates that spreads according to the present invention possess a better health effect.
