Title: Production of low-melting sorbitol and sorbitol candy
Inventor: KONO HIROYUKI
IPC: C07C31/26
Filed: 1989-11-29
Abstract: PURPOSE:To obtain low-melting sorbitol with a low moisture content capable of exhibiting specific values in heat of fusion, peak top temperature, etc., by differential scanning calorimetry and then obtain the subject transparent candy by adding the resultant low-melting sorbitol as a nuclear seed to a sorbitol melt. CONSTITUTION:Sorbitol regulated to <=10% moisture content is completely melted by heating and then slowly cooled. Previously prepared low-melting sorbitol powder as a nuclear seed is subsequently added thereto at 80-90 deg.C material temperature and the obtained mixture is homogeneously kneaded and then slowly allowed to cool to afford low-melting sorbitol. The resultant low- melting sorbitol has <=10% moisture content and >=80J/g heat of fusion measured by differential scanning calorimetry and 66-76 deg.C peak top temperature thereof without any further recognized peak in the heat of fusion. The above-mentioned low-melting sorbitol as a nuclear seed can be added to a sorbitol melt to regenerate sorbitol having the same physical properties in a short time. In producing candies, punching is carried out while the temperature is naturally increased throughout the cooling period of the aforementioned melt.
