CN1044433C - A method of producing soft candies - Google Patents

Abstract

There is disclosed a method of producing a soft candy showing remarkably reduced or practically no adhesion to teeth. According to the method, a saccharide mixture containing sugar and glucose syrup is thermally treated for adjusting its moisture content, and then an oil or fat is added to form the saccharide mixture.

Description

Produce the method for soft sweets

The present invention relates to the tooth adhesiveness is significantly lowered or in fact do not have the production method of adhering soft sweets (really).

Soft sweets are a kind of candies that children and women like very much.But its shortcoming is that tooth is had adhesiveness.

Two kinds of technical methods are arranged in preventing the routine techniques that soft sweets stick to one's teeth usually.First method is to add oil or fat (Japan Patent No Hei4 (A.D.1992)-84858 (A) in the composition of candy; R.Lee and E.B.Jackson, " Sugarconfectionery and Chocolate Manufecture ", pp.170,196; E.B.Jackson, " Sugar Confectionery Manufacture ", p.127 (1990)).These documents only relate to increase oil or fat addition to prevent the adhesion of soft sweets to tooth, the kind of oil or fat and in the process of producing soft sweets, it is added time of component openly.Therefore, can think that document only advised that preferential for this purpose what select is the emulsification of O/W type.

Generally be to select vegetable oil or fat (Japan Patent No.Sho57 (A.D.1982), it adds with sucrose, glucose or starch syrup, Evamilk or other, resulting mixture carries out homogenize under the condition of high water content (greater than 15%), then the heating of homogenize thing is concentrated its water content is transferred to predeterminated level (Japan Patent No.Hei4 (A.D.1992)-84858 (A)).

Second method is to add polyglycerol ester to stick to (Japan Patent No.Hei5 (A.D.1933)-7495 (A)) on the tooth as emulsifying agent to prevent soft sweets.But when the amount of emulsifying agent is when increasing the effect that prevents to adhere to, can occur the unpalatable influence of product, this knows.Therefore, the method is restricted.

The present inventor makes great efforts to study oil or fat significantly reduce or in fact do not have adhering soft sweets to the adhesiveness of tooth with preparation the condition that adds, they conscientiously study the emulsification mechanism of raw material, the sugar mixture heating that discovery will mainly contain sucrose and glucose concentrates and makes its water content not be higher than 10% (weight), under agitation add oil or fat then, with the concentrate of preparation soft sweets, the problem that adheres to tooth just can be prevented from significantly.

Refuel or the amount of fat preferably is not less than 2.0% and be higher than 30.0% (weight).Be lower than lower limit as its amount, the structure of keeping final soft sweets product ability can obviously reduce and can be observed oil or fat oozes out the surface in the preservation process of product.

If the emulsifying agent addition is the emulsifying agent that adds 2 weight portions in the oil of 100 weight portions or the fat, carry out mechanical homogenize then and handle, just can provide to tooth without any adhesive attraction and in the preservation process at surface observation less than the finished product that oozes out that oil or fat are arranged.

Used oil or fat can be selected following plant oil or fat, as neutral fixed oil, palm oil or the palm nucleolus oil that mainly contains rapeseed oil and corn oil, also can use other vegetable oil and tallow.Lecithin, sucrose fatty ester, D-sorbite fatty acid ester, polyglyceryl fatty acid ester etc. all can be classified emulsifying agent as.

Example, reference example and qualification test with reference to following will have more detailed understanding to the present invention.

Example 1

Based mixtures (is comprised sucrose, glucose syrup and Evamilk, each amount awards table 1) before heating, contain in 3 uncovered pans, each based mixtures (test 1,2,3) is heated to 115 ℃ (tests 1), 113 ℃ (test 2), 111 ℃ (test 3) respectively under stirring, its residue moisture (wetting) amount is transferred to value shown in the table 2).

Concentrate in each test pan is transferred to a Sigma type mixing and kneading machine, presses table 1 and give amount, fully mix with based mixtures to wherein adding vegetable oil commonly used or fat and lecithin.

The mixture that obtains in the mixing and kneading machine with test 1 cools off naturally, obtains the soft sweets that whole water capacity is 9.4% (weight).

Test 2 is shifted in the relevant pan again with mixture in 3 the mixing and kneading machine and is heated to 115 ℃ with further adjusting water capacity, cools off then, obtains soft sweets, and its whole water capacity respectively is 9.4% (weight).

Each sample products (test 1,2,3) of water capacity identical (9.4%) is carried out qualification test, and it the results are shown in table 4.Product is placed storeroom, and not observing has oozing out of oil ingredient from the teeth outwards.

Reference example 1:

The based mixtures of same composition shown in the table 1 (example 1) contained before heating go into a uncovered pan, fully mix, the water capacity of determining the gained mixture is 16% (weight).In the mixture that obtains, add vegetable oil and emulsifying agent, then fully mix, the homogeneous mixture heating that obtains is concentrated as example 1.

When the temperature of concentrate reaches 115 ℃, stop heating.Concentrate is transferred to Sigma type mixing and kneading machine, mediate with example 1 in the identical time.With the concentrate cooling of mediating, obtaining closing wet amount is the soft sweets of 9.4% (weight) then.

Said method is produced the method for soft sweets corresponding to routine.

The soft sweets that obtain are carried out qualification test by example 1 is described.It the results are shown in table 4.

Example 2

Before heating, based mixtures (comprise sucrose, glucose syrup, Evamilk, its amount awards table 3) is contained 4 uncovered pans.Each based mixtures (test 4,5,6,7) is heated to 118 ℃ (tests 4), 117 ℃ (test 5), 110 ℃ (test 6), 109 ℃ (test 7) respectively, makes their water capacity be lower than 10.0% (weight).

Concentrate in each test (test 4-7) pan is transferred to Sigma type mixing and kneading machine, presses table 3 amount of giving and add vegetable oil and lecithin, fully mix with based mixtures.

The mixture that obtains in the mixing and kneading machine with test 4-7 cools off naturally, obtains soft sweets, and its whole water capacity is 9.4% (weight).

In preservation, each product of test 4-6 is not all observed on its surface exudate, and the product surface of test 7 has exudate.Therefore will test 7 product discharge outside qualification test.Qualification test the results are shown in table 4.

Reference example 2

The based mixtures that will be same as test 6 (table 3, examples 2) composition is contained before heating in a uncovered pan, fully mixes, and the water capacity of the mixture that affirmation obtains is 17% (weight).Add as the vegetable oil in the example 1 and emulsifying agent and fully mixing.The homogeneous mixture that obtains is heated to regulate water capacity.When reaching 110 ℃, temperature stops heating.Concentrate is transferred to Sigma type mixing and kneading machine, stir to mediate the time identical with the test 6 in the example 2.After this, the concentrate that cooling is mediated obtains the soft sweets that water capacity is 9.4% (weight).

The soft sweets that obtain are cooked qualification test.The results are shown in table 4.

Qualification test

With example 1 and 2 and the soft sweets that obtain of reference example 1 and 2 carry out the sensory evaluation test, by 15 people's professional group evaluation.The results are shown in table 4.Result from table 4 is as can be seen:

(a) sample products of test 1-3 is starkly lower than the sample products that reference example 1 obtains to the adhesion of tooth.The latter produces with conventional method.

(b) sample products of test 1-2 is estimated preferably.

(c) product of the sample of test 3 shows the low relatively adhesiveness to tooth, but absolute product evaluation is " generally ".

(d) test 6 sample products has shown the higher adhesion of sample products that obtains than reference example 2, and the latter is to use conventional method.

(e) evaluation of testing 4 sample products has been shown the similar trend of product of the sample that obtains to reference example 2, promptly when oil or fat components contents are lower than 2.0% (weight), even adopt method of the present invention, the evaluation that also can not get.
