| Abstract: |
| In order to provide scientific guidance for the quality improvement and safe production of fragrant peanut oil, four kinds of commercially available starches (common starch, acetylated distarch phosphate, hydroxypropyl distarch phosphate, and starch acetate) were used as adsorbents, the removal rate of di(2-ethylhexyl) phthalate (DEHP) from fragrant peanut oil was used as an index, and the effects of type, addition amount, addition position, addition method of starch adsorbent and addition amount of fragrant peanut oil on the DEHP removal from fragrant peanut oil were investigated, and the effects of starch adsorbent on the quality of fragrant peanut oil were also examined. The results showed that four kinds of commercially available starch adsorbents were able to remove DEHP in the following order: starch acetate>hydroxypropyl distarch phosphate>acetylated distarch phosphate>common starch; the adsorption and removal method of adding starch acetate adsorbent to peanut kernels before roasting was used, and the removal rate of DEHP was 35.4% under the conditions of 1% of fragrant peanut oil and 2% of starch acetate addition. The DEHP removal effect of adding starch acetate adsorbent before roasting was better than that of adding it after roasting, and there was no obvious DEHP removal effect of adding starch acetate adsorbent directly to fragrant peanut oil. There was no obvious effect of starch acetate on the acid value, peroxide value, colour, transparency and flavour of the fragrant peanut oil. In conclusion, the addition of starch acetate adsorbent to peanut kernel before roasting can reduce the content of DEHP in fragrant peanut oil, and ensure the product quality of fragrant peanut oil. |
