Aroma addition experiments highlighted that 7 key aroma compounds had significant effects on the aroma intensity of the sensory attributes of milk fan at the concentrations measured in a milk fan sample, and they might have synergistic effects with other compounds. The components of the 7 aroma compounds in binary mixtures showed synergistic effects from 21 binary mixtures by Feller's additive model. The components of 9 mixtures showed synergistic effects in the superadditive region (σ > 1.05), and 3 mixtures showed additive effects in the additive region (0.95 less then σ less then 1.05) of the σ-τ diagrams for all 168 binary mixtures. The results showed that perceptual interactions among the key aroma compounds in milk fan vary with different concentrations and threshold ratios. These results are helpful for further understanding the aroma of milk fan and improving the quality of its aroma.Lactoferrin (LF), a sialylated iron-binding glycoprotein, has numerous vital physiological functions including immunomodulation and protection against a large group of microorganisms, improving neurodevelopment, health, growth performance, and milk production. Lactoferrin occurs in human milk at a higher concentration compared with bovine milk, but little information is available on LF concentrations in porcine milk and the effects of sow parity on milk LF concentration.
