To optimize the processing techniques of Vaccinium and Shayuan-Daucus carota sauce, and develop value-added products of Shaanxi Province Weinan Shayuan-Daucus carota.
Natural materials such as Shayuan-Daucus carota and Vaccinium were used as raw materials. Single factor experiments and orthogonal experiments were adopted to optimize the processing techniques of Vaccinium and Shayuan-Daucus carota sauce, with the sensory evaluation as the response value. Additionally, a nutritional composition analysis was performed.
The addition of honey had the most significant impact on the Vaccinium and Shayuan-Daucus carota sauce (P<0.05), followed by the ratio of Shayuan-Daucus carota to Vaccinium. The optimal process was as follows: The ratio of Shayuan-Daucus carota to Vaccinium was 2:1 (m:m); the addition levels of lemon juice, honey and potato starch were 3.5%, 9.0% and 1.0%, respectively, based on the total mass of Shayuan-Daucus carota and Vaccinium. The nutritional analysis results showed that the Vaccinium and Shayuan-Daucus carota sauce was rich in protein, fatty acids, vitamin A, carotene, as well as minerals such as potassium, sodium and iron. The 777.25 μg/100 g of β-carotene and 46.93 mg/kg of iron (27 times more iron than in fresh Shayuan-Daucus carota) were detected in the sauce. However, neither fat nor sucrose was detected.
The optimized processing technology developed in this study can yield Vaccinium and Shayuan-Daucus carota sauce with high nutritional content and free from chemical additives. The research will lay a solid theoretical foundation for the enhancement of added value and the promotion of industrial development of Shayuan-Daucus carota in Weinan, Shaanxi Province.
