Abstract

The invention discloses a grape essence for aromatic leather. The grape essence is prepared from the raw materials of, by weight, 1-40% of grape essence, 3-50% of composite modified oligosaccharide and the balance of deionized water. The invention also provides a preparation method of the above grape essence for aromatic leather. According to the invention, grape essence is mixed into composite modified oligosaccharide, such that essence molecules are cladded by the composite modified oligosaccharide, and the grape nano-capsule sustained-release essence which can be applied in a leather finishing agent is prepared. The invention also provides the leather finishing agent comprising the grape essence for aromatic leather. The grape essence for aromatic leather is applied in leather finishing. With the finish, the aromatic leather has a natural and harmonious aroma. When the leather is placed for 40 days, the aromatic leather has a good and long-lasting grape aroma.
