| Abstract: |
| In order to resolve the problem that edible coconut oil had strong flavor, but lack of essential fatty acids and oil concomitant, extraction process of nutrients fortified coconut oil (avocado coconut oil) from avocado pulp and coconut pulp using ultrasound-assisted enzymatic hydrolysis was studied. The preparation process was optimized by single factor experiment, and the quality characteristics of the oil were analyzed. The results showed that the appropriate preparation conditions of avocado coconut oil were obtained as follows: 30% of avocado pulp (based on coconut pulp mass), 0.25% of papain and 0.05% of pectin (based on the mass of total materials), enzymolysis temperature 60 ℃, enzymolysis time 1 h, ultrasonic time 2 h, centrifugation after freezing (-20 ℃) and defrosting(60 ℃,1 h) twice. Under these conditions, the yield of avocado coconut oil was 26.4%, the acid value was 0.36 mgKOH/g. The avocado coconut oil showed light green color and had specific aromatic flavor of both coconut and avocado, and strengthen the nutrient value of coconut oil with the contents of unsaturated fatty acid, total phenolic acid, carotenoids and flavonoids in 1055%, (0.24±0.15)mg/g, (0.61±0.03)mg/kg and (0.013±0.002)mg/mL, respectively. |
