Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sheet margarine release agent.

[0002]

2. Description of the Related Art In the confectionery and bakery manufacturing industries, when manufacturing pies, a sheet-shaped roll-in margarine for commercial use (in the present specification, the sheet-shaped roll-in margarine is referred to as "sheet margarine"). ) Is used.
This sheet is, for example, a square or rectangular sheet having a thickness of 8.5 to 10.5 mm and a weight of 500 g to 1 kg as a unit. At present, synthetic resin films (PE, PP, etc.) are laid on the front and back to release such a sheet margarine, and for example, several sheets are put in a case to form one package. Since the synthetic resin film is discarded after use, the disposal of this waste is a problem.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide means for releasing a sheet margarine from a mold without using a synthetic resin film.

[0004]

Means for Solving the Problems The present invention provides (1) water and sugar alcohol as essential components of an aqueous phase portion and hardened vegetable fats and oils as essential components of an oil phase portion, and a high HLB poly as an emulsifier. Glycerin fatty acid ester and low HL
It is intended to provide a sheet margarine release agent comprising an oil-in-water type emulsion obtained by emulsifying the polyglycerol fatty acid ester of B.

The present invention also provides (2) the sheet margarine release agent according to (1) above, which further comprises glycerin as a component of the water phase part and natural wax as a component of the oil phase part. It is provided.

The present invention also provides (3) the sheet margarine release agent according to (1) above, which further comprises ethanol.

In the present invention, (4) the hardened vegetable oil is at least one selected from soybean, rapeseed and hardened cottonseed oil, and the natural wax is at least one selected from beeswax, rice wax and carnauba wax. Seed,
The sugar alcohol is at least one selected from sorbitol, mannitol, reduced starch hydrolyzate, and reduced lactose, and the emulsifier having a high HLB is a polyglycerin fatty acid ester having a polymerization degree of 6 to 10, and the emulsifier having a low HLB is The sheet margarine release agent according to any one of (1) to (3), which is a polyglycerin fatty acid ester having a degree of polymerization of 4 to 6, is provided.

The present invention also provides (5) a sheet margarine release agent having the water content of 25% by weight or less based on the total amount of the sheet margarine release agent.

In the present invention, (6) the total amount of the oil phase components is 5 to 40 parts by weight with respect to the total amount of the water phase components of 60 to 95 parts by weight. 5) It provides the sheet margarine release agent according to any one of the above.

The present invention also provides (7) the sheet margarine release agent according to (1), which has a viscosity at 25 ° C. of 4000 to 10,000 cp.

Since the surface of the margarine is a hydrophobic surface, it is necessary to form a hydrophilic interface between the two sheets of margarine in order to release them from each other. In the present invention, a hydrophilic emulsion is prepared by using a concentrated sugar alcohol, glycerin in an aqueous phase part, and a hardened vegetable oil / fat having a melting point of 34 ° C. to 70 ° C. and a natural wax as an oil phase part. Interface. In the present invention, the fine powder of oil and fat obtained by high-speed emulsification is uniformly dispersed in the high-viscosity aqueous phase portion, whereby a releasing agent having a good releasability due to these synergistic effects can be obtained.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The sheet margarine release agent of the present invention is obtained by emulsifying an aqueous phase component and an oil phase component with an emulsifier. Water and sugar alcohol are essential components of the aqueous phase. Examples of sugar alcohols include sorbitol, mannitol, reduced starch hydrolysates, and reduced lactose. Further, if desired, glycerin can be added as a component of the aqueous phase portion from the viewpoint of adjusting the viscosity.

Next, as a component of the oil phase portion, hardened vegetable oil is essential. Examples of hardened vegetable oils and fats include hardened soybean oil, hardened rapeseed oil, hardened cottonseed oil, hardened palm oil, and hardened palm oil. These hardened fats and oils have a melting point of 34.
C to 70 ° C, preferably 50 to 70 ° C. If the melting point is less than 34 ° C, the melting point is too low to obtain the expected fine powder. On the other hand, when the melting point is higher than 70 ° C, the melting point is too high and it becomes difficult to prepare a stable emulsion. Further, if desired, a natural wax can be further added as a component of the oil phase portion from the viewpoint of adjusting the physical properties (hardness and the like) of the high melting point oil and fat. Examples of natural waxes include beeswax, rice wax, carnauba wax, candelilla wax, and wood wax.

In contrast to the components of the water phase portion and the components of the oil phase portion, when emulsified, the components of the water phase portion have high HLB (11 to 11).
14) Polyglycerin fatty acid ester as an emulsifier of
Low HLB (4-5) polyglycerin fatty acid ester is added to the oil phase component. The degree of polymerization of the high HLB polyglycerin fatty acid ester is preferably 6-10. If the degree of polymerization deviates from this range, the emulsifying power required by the present invention cannot be obtained. Such high HLB polyglycerin fatty acid ester has a trade name of SY Glystar NSW-750, MO-75.
0 and MS-500 from Sakamoto Yakuhin Kogyo Co., Ltd.
Also, it can be obtained from Riken Vitamin Co., Ltd. as Poem J-0081H. The degree of polymerization of the low HLB polyglycerin fatty acid ester is preferably 4-6. If the degree of polymerization deviates from this range, the emulsifying power required by the present invention cannot be obtained.
Such low HLB polyglycerin fatty acid esters are commercially available under the trade names SY Glister TS-310, PS-500 and PO.
-500 is available from Sakamoto Yakuhin Kogyo Co., Ltd.

The amount of water as an essential component of the aqueous phase is 15% by weight or less based on the total amount of the sheet margarine release agent. Here, the shelf life of roll-in margarine is 3 months to 10 months when refrigerated (0 to 10 ° C), so long-term releasability at low temperatures and stability of quality including hygiene are releasable. Required for agents. For this reason, the water content in the water phase is minimized (25% or less) and the water activity value is adjusted to 0.85 or less.

The total amount of the oil phase components is 5 to 40 parts by weight with respect to the total amount of the water phase components of 60 to 95 parts by weight. If it deviates from this range, the target releasability will be poor. The emulsion contains 1 to 100 parts by weight of the total amount of the emulsion for the purpose of improving the storage stability of the emulsion.
10 parts by weight of ethanol can be added.

The sheet margarine release agent of the present invention can be prepared as follows. 60 parts by weight to 9
5 parts by weight of each component of the aqueous phase are heated and mixed at 80 ° C.,
5 parts by weight to 40 parts by weight of each component of the oil phase portion, which was heated and dissolved at 0 ° C., were prepared, and the oil phase portion was gradually stirred while stirring the water phase portion with a TK homomixer (manufactured by Tokushu Kika Co., Ltd.). Mix to give an emulsion (3000 to 5000 revolutions, 10-30 minutes). This emulsion is cooled to 45 ° C. or lower, or, if desired, ethanol is added to the emulsion at 1: 1 with a mixer.
The sheet margarine release agent of the present invention having a water activity of 0.85 or less is obtained by mixing 1 part by weight to 10 parts by weight at low rotation so as not to foam.

In the sheet margarine release agent of the present invention thus obtained, waste can be drastically reduced by using a release agent which does not affect the quality of margarine instead of the synthetic resin film.

As a method of using the sheet margarine release agent of the present invention, the release agent is applied by a spray or a roller at an arbitrary position in the roll-in margarine production line, and spray application is preferable from the viewpoint of hygiene.
The viscosity that can be used for spraying is appropriately 12,000 cp (B-type viscometer No. 4 rotor 30 rpm, 25 ° C.) or less, and the correlation between the viscosity and the releasability is considered from the results of Examples 1 to 10 and Table 1 described later. In order to improve the wetting of the release agent on the surface of the margarine (the lower the viscosity, the lower the surface tension of the hydrophobic surface), a certain degree of high viscosity is required. Therefore, the viscosity is 4000 to 10,000 cp ( 25 ° C) is preferred.
