| Abstract: |
| In order to investigate the feasibility of using sunflower seed oil body enrichment in ice cream,low fat ice cream was prepared with sunflower seed oil body enrichment as the fat under the condition of non-homogenization. The effect of the dosage of the oil body enrichment on the quality of low fat ice cream slurry and product was explored. The results showed that the viscosity, storage modulus and loss modulus of ice cream slurry increased with the increase of the oil body enrichment dosage. When the dosage of oil body enrichment was 3.5%- 4.0%, the viscosity was equivalent to that of the control group. The proportion of non-flowing water and bound water in the slurry increased gradually with the increase of the dosage of oil body enrichment, reaching the maximum at 4.0%. The expansion rate and anti-melting rate of ice cream products first increased and then decreased as the increase of the oil body enrichment dosage. The color of ice cream with sunflower seed oil body enrichment was poor. The hardness and chewability of ice cream showed the same change law, which first decreased and then increased with the increase of the oil body enrichment dosage,while the elasticity changed in the opposite direction. The adhesion of ice cream increased with the increase of the oil body enrichment dosage. The sensory score of ice cream was the highest when the dosage of oil body enrichment was 2.5%. The appropriate dosage of sunflower seed oil body enrichment can produce a similar effect as palm oil, and sunflower seed oil body enrichment can be applied in ice cream. |
