The application of chili oil resin emulsion in brined Duck Necks
The duck necks were brined using the prepared emulsion with chili oil resin and a company's brine,and HPLC and GC-IMS were used to determine the pH value,refractive index,color,spiciness and volatile organic com-pounds and the differences between the emulsion with chili oil resin to the company's brine were also analyzed;the quality differences between duck necks brined using the emulsion with chili oil resin and a company's brine were an-alyzed via determining the color,moisture content,water activity,spiciness,textural properties and volatile organic compounds and the effects of brining cycles on the quality changes of the emulsion with chili oil resin and brined duck necks were explored.The results showed that there was no significant difference in pH value between the e-mulsion with chili oil resin and the company brine,and the refractive index,color,and capsaicin content were signif-icantly higher than that of company brine(p＜0.05);the color,hardness,chewiness and spiciness of brined duck necks with the chili oil resin emulsion were significantly higher than that of the company(p＜0.05);the moisture content,water activity and elasticity were insignificant differences(p＞0.05).As the number of brining cycles in-creased,the pH value,refractive index,color and capsaicin content of the emulsion with chili oil resin decreased sig-nificantly(p＜0.05),while the moisture content,water activity and resilient of brined duck necks changed not sig-nificantly(p＞0.05).There were 41 volatile organic compounds found in the brine and brined duck necks,inclu-ding 16 esters,4 alcohols,4 aldehydes,2 phenols,5 ketones,2 ethers,3 acids and 5 other categories.The volatile organic compounds in the emulsion with chili oil resin were more than in a company's brine;the aldehydes in the brined duck necks with chili oil resin emulsion were more than in a company's brined duck necks,which had a bet-ter overall flavor.After brining cyclic,the volatile organic compounds of the emulsion with chili oil resin were simi-lar to the brined duck necks.These results indicated that the overall quality of the emulsion with chili oil resin and its brined duck necks was superior to that of the company;however,brining cyclic would decrease the quality of the emulsion with chili oil resin and brined duck necks.
