Definitions
- the present invention relates to chocolates with fats and oils as a continuous layer.
- the melt in the mouth of chocolate is attributed to the fact that the fats and oils contained in the chocolate dough melt sharply near body temperature, but at the same time, the melted chocolate exhibits high stickiness that sticks to the oral cavity wall. It causes a feeling of lingering. In the present application, this is expressed as sticky feeling during mastication and swallowing.
- Patent Document 1 describes a chocolate that exhibits a sharp melting in the mouth of conventional chocolate, while significantly reducing the stickiness of chocolate eluted in saliva, and leaving a refreshing feeling in the mouth with little aftertaste, which was difficult with conventional technology.
- SOS triglyceride saturated fatty acid
- O oleic acid
- a texture modifier for tempering chocolate comprising
- white chocolate and milk chocolate are composed mainly of cocoa butter and whole milk powder, so the taste of the milk component is emphasized and the aftertaste is very bad.
- Techniques for incorporating polyphenols have been disclosed for the purpose of improving such taste and producing a mellow and refreshing aftertaste and a sharp taste.
- Patent Document 3 discloses a technique for containing a specific amount or more of medium-chain fatty acid-bound triglycerides in order to reduce the powdery texture of chocolate rich in non-fat cacao solids.
- Patent Document 1 has the problem that the adhesive properties of chocolate must be changed in order to reduce the stickiness in the mouth of chocolate eluted in saliva, making it difficult to freely adjust the physical properties of chocolate. rice field.
- Patent Document 2 describes that adding a polyphenol-containing extract composition from green tea leaves to chocolate or white chocolate is effective in improving the aftertaste. There was a concern that it would lead to modification of the chocolate flavor.
- Patent Document 3 uses medium-chain fatty acid-bound triglycerides as a technology for improving the texture of chocolate, it does not describe chocolate containing non-fat milk solids, and the problem is different from that of the present application.
- the object of the present invention is to provide a method for reducing the sticky feeling during chewing and swallowing, which is a problem peculiar to chocolates containing a large amount of non-fat milk solids derived from powdered milk.
- the present inventors found that chocolates containing 15% by weight or more of non-fat milk solids significantly give a sticky feeling when chewing and swallowing. Furthermore, by containing 0.85% by weight or more of medium-chain fatty acid-bound triglycerides generated by a randomization process such as transesterification or ester synthesis, the sticky feeling can be reduced and a sharp texture can be obtained. and completed the present invention.
- the present invention (1) Chocolates containing 0.85 to 15.0% by weight of medium-chain fatty acid-bound triglycerides derived from randomized fats and containing 15% by weight or more of non-fat milk solids, provided that the medium-chain fatty acids have 6 carbon atoms.
- the present invention it is possible to reduce the sticky feeling of chocolates containing a large amount of non-fat milk solids such as white chocolate and milk chocolate. It can be a product that suits your taste.
- chocolates are oil-and-fat processed foods in which oils and fats form a continuous phase, and not only chocolate, quasi-chocolate, and chocolate-based foods specified by the National Chocolate Industry Fair Trade Council and the Chocolate-based Food Fair Trade Council, Fats and oils and milk powder are essential ingredients, and if necessary, auxiliary ingredients such as sugars, cacao raw materials (cocoa mass, cocoa, cocoa butter), fruit juice powder, fruit powder, flavoring agents, emulsifiers, flavors, coloring agents, etc. Say what you mixed. Typical examples of chocolate include milk chocolate and white chocolate. Moreover, strawberry chocolate etc. which added the fruit component to these are also included.
- the chocolates of the present invention must contain 15 wt% or more non-fat milk solids, preferably 16 wt% or more, more preferably 17 wt% or more, even more preferably 18 wt% or more, most preferably 19 wt% or more. % by weight or more, and most preferably 20% by weight or more. If the non-fat milk solids content is 15% by weight or more, the food will obviously feel sticky when eaten, so it is necessary to improve the texture.
- the chocolates of the present invention preferably contain milk powder in an amount of 20 to 50% by weight, more preferably 23 to 40% by weight.
- non-fat milk solids are solids obtained by removing milk fat from components derived from powdered milk such as whole milk powder and skimmed milk powder.
- the chocolates of the present invention must contain 0.85% by weight or more, preferably 0.9% by weight or more, more preferably 0.95% by weight or more of medium-chain fatty acid-bound triglycerides derived from randomized fats and oils. , more preferably 1% by weight or more, most preferably 1.5% by weight or more, still most preferably 5% by weight or more, and next preferably 10% by weight or more. Moreover, it is preferably 30% by weight or less. If the medium-chain fatty acid-bound triglyceride content is 0.85% by weight or more, stickiness during eating is improved.
- the medium-chain fatty acid-bound triglyceride of the present application is a triglyceride in which at least one of the constituent fatty acids is a medium-chain fatty acid. That is, the medium-chain fatty acid-linked triglycerides of the present application include 3 medium-chain triglycerides and medium- and long-chain mixed acid group triglycerides (2 medium-chain 1 long chain and 1 medium-chain 2 long-chain triglycerides).
- medium-chain fatty acids are fatty acids having 6 to 10 carbon atoms
- long-chain fatty acids are fatty acids having 12 to 22 carbon atoms.
- medium-chain fatty acid-bonded triglycerides of the present application medium- and long-chain mixed acid group triglycerides have a higher effect of improving stickiness during eating than three medium-chain triglycerides.
- the ratio of unsaturated fatty acid to saturated fatty acid (long-chain unsaturated/saturated) in the long-chain fatty acid of the mixed acid group triglyceride is preferably 2.5 or more, more preferably 3.0 or more, further preferably 3.5 or more. It is preferable that the ratio of unsaturated fatty acid to saturated fatty acid is 2.5 or more because stickiness during eating is improved.
- the randomized oils and fats from which the medium-chain fatty acid-bonded triglycerides of the present invention are derived can be prepared by random transesterification or ester synthesis. Random transesterified oils and ester synthetic oils usually have a random distribution of fatty acids on the triglyceride molecules.
- Random transesterification of fats and oils is known to use sodium methylate, sodium ethylate, alkali metals such as sodium, sodium hydroxide, potassium hydroxide, etc. as catalysts. It is preferable to use sodium methylate because of its easiness.
- a method using a fat-degrading enzyme (lipase) as a catalyst is also known, and any method may be used.
- the ester synthesis reaction of fats and oils is a method for producing fats and oils by dehydrating and condensing fatty acids and glycerin under reduced pressure conditions, and is used, for example, in the production of MCT oils (medium-chain fatty acid fats and oils).
- the medium-chain fatty acid-bound triglycerides of the present application are derived from randomized fats and oils, the fatty acids are randomly distributed on the triglyceride molecule.
- the abundance ratio of MML is 1:2 (M: medium chain, L: long chain).
- M medium chain
- L long chain
- C8C10C8 and C8C8C10 is 1:2.
- the medium chain linked triglycerides of the present application should be randomly distributed.
- medium-chain fatty acid-bonded triglycerides of the present application medium- and long-chain mixed acid group triglycerides are produced by random transesterification between MCT oil and long-chain fatty acid fat.
- the long-chain fatty acid fat is preferably a liquid oil mainly containing an unsaturated fatty acid having 18 carbon atoms.
- the above-mentioned liquid oil is an oil that is liquid at room temperature and contains mainly an unsaturated fatty acid having 18 carbon atoms among its constituent fatty acids.
- liquid oils include rapeseed oil, soybean oil, corn oil, safflower oil, cottonseed oil, sunflower oil, palm oil and the like.
- processed oils and fats that are liquid at room temperature which are obtained by subjecting these oils and fats to one or more of physical or chemical treatments such as hydrogenation, fractionation, and transesterification, can also be mentioned.
- liquid oil of the present invention corn oil and sunflower oil are preferably used, and corn oil is more preferably used.

に関するものである。
チョコレート類の代表的な例としては、ミルクチョコレート、またホワイトチョコレートを列挙できる。また、これらに果実成分を加えたような、イチゴチョコレート等も含まれる。
また本発明のチョコレート類は、粉乳を20~50重量%含むことが好ましく、より好ましくは23~40重量%である。
ここで無脂乳固形分とは、全脂粉乳や脱脂粉乳などの粉乳に由来する成分から乳脂肪を除いた固形分である。
中鎖脂肪酸結合トリグリセリドを0.85重量%以上含有すると喫食時のねちゃつきが改善される。
ここで中鎖脂肪酸は炭素数6~10の脂肪酸、長鎖脂肪酸は炭素数12~22の脂肪酸である。
不飽和脂肪酸と飽和脂肪酸の比率が2.5以上であると喫食時のねちゃつきがよりよく改善されるため好ましい。
油脂のエステル合成反応は、脂肪酸とグリセリンを減圧条件下で脱水縮合させる油脂の製造法であり、例えばMCT油(中鎖脂肪酸油脂)の製造に用いられている。
このように本願の中鎖結合トリグリセリドはランダム分布になっている必要がある。
上記液状油としては、構成脂肪酸中に炭素数18の不飽和脂肪酸を主体として含む常温で液状の油脂である。液状油として、例えば、菜種油、大豆油、コーン油、紅花油、綿実油、ヒマワリ油、パーム油等が挙げられる。また、これらの油脂に水素添加、分別、エステル交換等の物理的又は化学的処理の1種又は2種以上の処理を施した常温で液状の加工油脂を挙げることができる。本発明の液状油として、コーン油、ヒマワリ油を用いるのが好ましく、より好ましくはコーン油を用いるのが良い。
(エステル交換油1)
コーン油95部、MCT油(不二製油株式会社 商品名:MCT-64)を5部混合した油脂を原料に、ナトリウムメチラートを用いてエステル交換を行い、得られた油脂を常法に従い精製を行いエステル交換油1を得た。
(エステル交換油2)
コーン油82部、MCT油(不二製油株式会社 商品名:MCT-64)を5部、ハイオレイックひまわり油5部、ハイオレイックひまわり油の極度硬化油8部を混合した油脂を原料に、ナトリウムメチラートを用いてエステル交換を行いエステル交換油2を得た。
(コーン油)
コーン油を用いた。
(MCT油)
MCT油(不二製油株式会社 商品名:MCT-64)を用いた。
(パームスーパーオレイン)
パームスーパーオレイン(ヨウ素価67、不二製油株式会社 商品名:パームエース10)を用いた。
上記各油脂組成物のトリグリセリド組成を表1に示す。
・3中鎖トリグリセリド(C24-30の和)
・2中鎖1長鎖トリグリセリド(C32-38の和)
・1中鎖2長鎖トリグリセリド(C40-46の和)
・上記三者の合計量である中鎖脂肪酸結合トリグリセリド(C24-46の和)
構成脂肪酸中の中鎖及び長鎖脂肪酸含量並びに固体脂指数(SFC)を表2に示す。
・上記にて調製した配合用油脂を用いて、表3の配合を基に常法に従いホワイトチョコレート生地を得た。
・上記チョコレート生地を50℃以上で溶解後、13℃の冷水で冷却しながら31℃まで温度を下げた。
・シード剤(不二製油株式会社製/商品名「チョコシードA」)をチョコレートに対し0.2重量%加えてテンパリング処理し、モールドに流しいれた。
・10℃で30分冷却、デモールドした。
・20℃にて1週間エージングして、各チョコレートを作成した。
・各チョコレート中の無脂乳固形分及び配合用油脂由来の中鎖脂肪酸結合トリグリセリド含量を表3に示す。
・チョコレート油脂の開発業務に携わり、よく訓練された7人のパネラーにより、下記評価基準に従い作成したチョコレートの咀嚼、嚥下時のねちゃつき感を評価した。官能評価結果を表3に示す。
咀嚼、嚥下時のねちゃつき感評価(3点以上を合格とした)
1点 咀嚼時にねちゃつき感を強く感じる。
2点 咀嚼時にねちゃつき感を若干感じる。
3点 咀嚼時にねちゃつき感を若干感じるが許容範囲である。
4点 咀嚼時にねちゃつき感は感じられない。
5点 咀嚼時にねちゃつき感は感じられず、嚥下時にキレ感あり。
一方コーン油とMCT油のエステル交換油1を用いた実施例1のチョコレートは、中鎖脂肪酸結合トリグリセリドを3.2重量%含んでおり、5点と良好な食感を示した。
またMCT油を用いた実施例2のチョコレートは中鎖脂肪酸結合トリグリセリドを15重量%と多量含んでおり、5点と良好であった。但し実施例1に比べ多量の中鎖脂肪酸結合トリグリセリドを含むにもかかわらず、食感評価は同等であり、ねちゃつき感改善に対する力価はMCT油よりもエステル交換油1の方が優れていると考えられた。
比較例1のチョコレートは、コーン油とMCT油を用いている。一方実施例1に用いたエステル交換油1の反応前の原料は同量のコーン油とMCT油である。両者の違いはランダム化されているか否かの点のみであるが、実施例1のチョコレートは5点で合格、比較例1のチョコレートは2点で不合格であった。同じ原料油脂であってもランダム化により、ねちゃつき感改善効果に明確に差があることが判る。
・エステル交換油1を配合用油脂に用いて、表4の配合を基に常法に従いチョコレート生地(油分45%)を得る以外はテストAと同様にして実施例3のホワイトチョコレートを作成し食感を評価した。
・エステル交換油1及びエステル交換油2を配合用油脂に用いて、表5の配合を基に常法に従いイチゴチョコレート生地(油分41.1%)を得る以外はテストAと同様にしてチョコレートを作成し食感を評価した。
実施例5に用いたエステル交換油2の炭素数16~22の(不飽和/飽和)比率は3.8であり、エステル交換油1の5.7に比べ低く、炭素数16~22の不飽和脂肪酸が少ないことが原因である可能性が示唆された。
中鎖脂肪酸結合トリグリセリドをどれだけ含有すればチョコレートに所期の効果が得られるかを検討する。
パームスーパーオレイン及びエステル交換油1を配合用油脂に用いて、表6の配合を基に常法に従い実施例6,7及び比較例6,7のホワイトチョコレート生地を得る以外はテストAと同様にしてチョコレートを作成し食感を評価した。
一方中鎖脂肪酸結合トリグリセリドを1.1重量%含む実施例7のチョコレートは5点と良好な食感を示し、合格であった。中鎖脂肪酸結合トリグリセリドを0.9重量%含む実施例6のチョコレートは3点と許容範囲の食感を示し、合格であった。
中鎖脂肪酸結合トリグリセリドによる後味のキレ付与効果とチョコレート中の無脂乳固形分との関係を検討する。
パームスーパーオレイン及びエステル交換油1を配合用油脂に用いて、種々の無脂乳固形分のホワイトチョコレート又はミルクチョコレートを表7の配合を基に常法に従い、テストAと同様にして作成し食感を評価した。結果を表7に示す。
テンパリングタイプハードバターとして不二製油株式会社製「メラノSS600」を用い
た。
中鎖脂肪酸結合トリグリセリドを含まない比較例8,9,10,12,14のチョコレートの評価結果から、無脂乳固形分が多ければねちゃつきを強く感じることが判る。また無脂乳固形分が18.7重量%,16.4重量%の比較例8、9に対して中鎖脂肪酸結合トリグリセリドを1.1重量%含む実施例8、9はねちゃつき感が改善されていた。
比較例8のチョコレートにおいてパームスパーオレインに代えて乳脂を配合して、比較例15のチョコレートを作成した。評価の結果、比較例8と同じく咀嚼、嚥下時のねちゃつき感は1点であり不合格であった。
乳脂は構成脂肪酸中に数重量%の中鎖脂肪酸を含んでいるので、中鎖脂肪酸結合トリグリセリドを含む可能性があるが、ねちゃつき感改善効果は見られなかった。ちなみに乳脂の構成脂肪酸はランダム分布しておらず、ランダム化された油脂ではない。
