没食子酸丙酯对仔猪浓缩料氧化稳定性的影响
Effect of propyl gallate on the oxidative stability of piglet concentrate feed
摘要
Abstract
To study the effect of propyl gallate(PG)on storage stability at different temperature and feed moisture,L9(33)orthogonal experimental design was used to explore the effects of PG dosage(0%,0.05%and 0.10%)on total antioxidant capacity(T-AOC),peroxide value(POV),acid value(AV)and vitamin A mass fraction of concentrate feed in piglets at different temperatures(25℃,30℃ and 35℃)and moisture(9%,16%and 19%).The results were shown as follows.1)PG addition had an extremely significant effect on T-AOC(P<0.01).The loss of vitamin A and AV of feed were reduced with 0.10%PG supplement.Therefore,PG addition enhanced the stability of feed.2)Temperature had a significant effect on POV,AV and mass fraction of vitamin A(P<0.01).The mass fraction of vitamin A was declined,but POV and AV increased with the increase of temperature.3)Moisture of feed was the main factor affecting AV of feed(P<0.01),and AV of feed was increased with the increase of moisture.To sum up,the addition of PG can improve the antioxidant capacity of feed,inhibit lipid hydrolysis,and reduce the loss of vitamin A in feed.The optimal dosage of PG in concentrate feed is 0.1%under 25~30℃and moisture of 9%~16%.关键词
