Definitions
- the present invention relates to a process for producing a butter-like w/o emulsion spread, particularly a spread with a reduced or low fat content.
- the present invention relates to a process for producing a butter-like w/o emulsion spread containing a fat with a relatively high level of fat solids, part of said fat being present in granular form.
- butter-like spreads plastic, cool melting products giving an oral response, particularly a palate breakdown which closely approaches that of dairy butter.
- a fat with a high level of fat solids we mean fats which at refrigerator temperatures (5-10°C) have a level of crystallized fat higher than 25% and preferably from 40-85%.
- reduced fat spreads we mean spreads containing less than 70% fat and preferably containing 55-65% fat, whereas by low fat spreads we generally mean spreads containing 20-55%, preferably 30-50% fat.
- a major problem with reduced fat spreads using conventional fat blends is that the palate melting behaviour is clearly different than that of higher fat products such as butter. The most obvious reason for this is the reduced amount of solid fat in the product.
- An advantage of the fats used in this invention is that the amount of solid fat they confer in the reduced fat spread approaches that to be found in conventional high fat products.
- the process according to the invention for producing butter-like w/o emulsion spreads is characterized in that
- an o/w emulsion cream is produced from an aqueous phase and a fat with a high level of fat solids as hereinbefore defined
- a w/o emulsion is produced from an aqueous phase and the remainder of the fat of the fatty phase which preferably contains fat components of lower fat solids, i.e. lower melting components;
- both emulsions are cooled to a temperature achieving crystallization of at least part of the fat present in each emulsion
- the crystallized emulsions are mixed and further cooling and working of the mixture of both emulsions are carried out to achieve further crystallization and obtain a w/o emulsion spread containing fat globules of an average size not exceeding 20 micrometer and preferably ranging from 3-6 micrometer.
- the high solids fat is preferably concentrated in the o/w emulsion cream.
- aqueous phase is thickened or gelled with a thickening or gelling agent which can be incorporated in either the o/w emulsion or in the w/o emulsion or in both the o/w and the w/o starting emulsions.
- Such gelling and thickening agents may include any of the substances well known in the art. However, those are preferred which are setting slowly or whose setting can be delayed by controlling the temperature and the shear conditions during processing.
- Preferred thickening/gelling agents are gelatin, i-carrageenan calcium alginate, milk proteins or mixtures thereof.
- the aqueous phase of the spreads preferably contains 1- 15 wt.% milk protein such as sodium caseinate and 1-5 wt.% gelatin, based on the aqueous phase.
- Setting of the aqueous phase is preferably delayed until at least 5% and preferably 20-80% of the crystall izable fat has crystallized.
- both the w/o and the o/w emulsions are cooled independently in a Votator ® A unit operating at 500-1500 r.p m.
- the super-cooled emulsions are subsequently brought together in a Votator ® C unit operating at 1500-3000 r.p.m. whereby crystallization of the fat takes place and setting the aqueous phase is initiated.
- the emulsion can be further processed through a second Votator ® C unit operating at 500-1500 r.p.m., in which crystallization and setting are completed.
- the o/w emulsion can be mixed in variable amounts, in line with the w/o emulsion.
- the ratio of o/w emulsion to w/o emulsion will vary from 1.5 to 1:1 preferably from 1:5 to 2.5:5.
- the fat in the fatty phase preferably contains suitable quick crystallizing, sharp melting fats, i.e. fats which contribute to avoidance of waxiness on consumption of the spreads because, at body temperature they do not contain any crystallized fat.
- Suitable quick crystallizing fats include hydrogenated lauric fats such as palmkernel oil, coconut oil, babassu oil, murumuru oil, ouricuri oil, which are rich in C 12 -C 14 fatty acids, further tallow fat or fractions thereof, butterfat or fractions thereof or mixtures of said fat. Formation of fat globules and fat granules is promoted by the presence in the fatty phase of a high solids fat displaying the following fat solids profile expressed in percentages determined by nuclear magnetic resonance (NMR) at the indicated temperatures:
- NMR nuclear magnetic resonance
- Appropriate fats (i) to be Incorporated in the fatty phase comprise wet and dry fractionated fractions of palm oil characterized by the following triglyceride composition:
- SSS triglycerides 1-9 wt.%; SOS triglycerides : 30-75 wt.%; SSO triglycerides : 3-12 wt.%,
- Suitable is a wet fractionated palm mid-fraction, characterized by the following triglyceride composition :
- the high solids fat are concentrated in the starting o/w emulsion cream.
- the fat phase will comprise 10-80 wt.% of high solids fat and 90-20 wt.% of other oils and fats of a triglyceride composition such that the total fat blend has the following fat solids profile :
- a w/o pre-mix emulsion of the following composition was prepared by mixing the ingredients at 60°C.
- the fat blend consisted of a mixture of 60% soybean oil hydrogenated to a melting point of 38°C and 40% of a randomly interesterified mixture of 40% palm oil and 60% palmkernel oil.
- the gelatin was added after homogenization of all other ingredients of the cream.
- the cream was first fed into a Votator ® A unit operating at 1,000 r.p.m., followed by a Votator ® C 1 crystallizer unit operating at 1,000 r.p.m.
- Precrystallized cream containing at least 50 wt.% solid fat left the C 1 unit at 5°C and was mixed in line with the pre-crystallized w/o emulsion (containing about 7 wt.% fat solid)/ which was first fed into a Votator A 2 unit operating at 1/000 r.p.m. (outlet temperature 13°C) and subsequently fed into a Votator ® C 2 unit operating at 2,000 r.p.m.
- the mixture of the two emulsions in the Votatorv ® C 2 unit was allowed to crystallize further and the aqueous phase to set.
- the temperature of the emulsion leaving the C 2 unit was about 17oC.
- This emulsion was further fed into a Votator ® C 3 unit operating at 1,000 r.p.m.
- the temperature of the product leaving this unit was 10°C and was ready for packaging.
- the average residence time in the A unit was 3 sec. and in the C units 3 min.
- a w/o (pre-mix) emulsion was produced following the procedure of Example 1. This pre-mix had the following composition: wt.%
- the cream and the w/o emulsion were blended in line in the ratio 1:1.
- the resulting spread had the following approximate composition : wt . %
- the hardness (C value) of the product measured at 5°C was about 1,000 g/m 2 .
- the product was fairly plastic and had good spreadability at refrigerator temperature. On consumption, the product was perceived as cool.
- Photomicrographs of the product were taken, using phase contrast at a magnification of 400.
- the water drops and granules appeared as bright and dark spots.
- the average size of the granules was approx. 5 micrometer.
- the processing line can be illustrated as follows :
- the resulting product had the following approximate composition : wt.%
- the average residence time in the A unit was 3 sec. and in the C units 3 min.
- the level of crystallized fat in the pre-crystallized w/o emulsion was at least 5% based on fat, before the aqueous phase was allowed to set.
- the level of crystallized fat in the pre-crystallized o/w emulsion cream was at least 10% based on fat, before the aqueous phase was allowed to set.
- the hardness (C value) of the product measured at 5°C was approx. 1700 g/cm 2 .
- the product was fairly plastic and had good spreadabili ty at refrigerator temperature. On consumption, the product was perceived as cool.
- a w/o (pre-mix) emulsion was produced following the procedure of Example 1. This pre-mix had the following composition : wt.%
- the cream and the w/o emulsion were blended in line in the ratio 1:1.
- the processing line can be illustrated as follows :
- the product was fairly plastic and had good spreadability at refrigerator temperature. On consumption, the product was perceived as cool.
- Example 3 was repeated without the granulation process
- the fat phase of the cream and that of the w/o emulsion were combined to obtain a single fat phase.
- This fat phase was combined with the aqueous phase ingredients to give a single w/o pre-mix.
- This pre-mix was processed by passage along a processing line illustrated as follows :
- Example 3 The products obtained from Example 3 and the Comparative Example were compared. Although the products had similar C-values (hardness), the product of Example 3 was much more plastic on spreading. At 5°C the product of Example 3 gave a collar value of 2 whereas the product of the Comparative Example gave a collar value of 5.
