Optimization of Soybean-Peptide Beverages Formulation by Using Fuzzy Logical Sensory Evaluation
Abstract:
Soybean-peptide, sugar, citric acid and concentrated orange juice as the raw material, orthogonal design and fuzzy logical sensory evaluation were applied together to obtain the best formulation of the soybean-peptide beverages. A L9 (34) orthogonal array design (OAD) was adopted to prepare nine soybean-peptide beverages. By using fuzzy logical sensory evaluation, the acceptability of these samples was studied. The results indicated that the ranking of sensory attributes for the beverage as follows: Taste > Color > Odor > Appearance; the order of the influence of the raw materials to the acceptability for the beverage as follows: Concentrated orange juice > Soybean-peptide > Citric acid > Sugar; and the best formulation of the soybean-peptide beverages is 5% Peptide-powder, 8% sugar, 0.05% citric acid and 5% concentrated orange juice.
