作者： Xiangyuan Wen Dequan Zhang Su Wang Zhiyuan Xiao Xin Li Debao Wang Wei Yang Chengjun Min Chengli Hou Institute of Food Science and Technology， Chinese Academy of Agricultural Sciences， key laboratory of agro-products quality and Safety Control in Storage and Transport Process， Ministry of Agriculture and Rural Affairs Institute of Agricultural Product Processing and nutritional health， Chinese Academy of Agricultural Sciences (Cangzhou) Sunrise Material Co.， Ltd Jiangyin Beijing Ershang Meat Food Group Co.， Ltd

Microbial growth causes lamb spoilage. This study explored the spoilage ability of Latilactobacillus sakei (L. sakei)， Serratia proteamaculans (S. proteamaculans) and Hafnia proteus (H. proteus) in vacuum-packed raw lamb， including growth ability， degradation of protein and lipid， and change of volatile organic compounds (VOCs) profile， meanwhile screened the key VOCs produced by the targeted strains with meat background excluding， finally confirmed the volatile spoilage marker of vacuum-packaged lamb by comparing with our previous work. The results showed that L. sakei， S. proteamaculans and H. proteus had excellent growth ability. L. sakei inoculated group significantly reduced the pH value， showed higher TCA-soluble peptides content， and excellently degraded sarcoplasmic and myofibrillar proteins. About free amino acids， L. sakei significantly degraded serine， arginine and aspartic acid， while S. proteamaculans and H. proteus significantly degraded serine and lysine. In addition， L. sakei had a strongest effect on promoting free fatty acids production， followed by S. proteamaculans and finally H. proteus. Evaluating from various indicators， the co-culture of the three strains did not have any effect. The key volatiles produced by L. sakei were 1-hexanol， acetic acid and hexanoic aicd， S. proteamaculans were 1-hexanol and acetoin， and H. proteus was 1-hexanol， acetic acid and acetoin. In the end， 1-hexanol， hexanoic acid and acetoin were proven to be spoilage markers for vacuum-packaged and chilled lamb. This study can provide fundamental information for inhibiting and rapid identification of spoilage in vacuum-packaged lamb.

This experiment aimed to evaluate the impact of dietary hydroxyproline(Hyp) supplementation on the muscle quality of juvenile Pacific white shrimp(Litopenaeus vannamei) fed a low fishmeal diet. Six formulated diets included one high fishmeal(HF; 25% fishmeal content) and five low fishmeal diets(10%fishmeal content) with 0%, 0.2%, 0.4%, 0.6% and 0.8% Hyp(LF0, LF2, LF4, LF6 and LF8, respectively). Each diet was assigned to four replicates, and 40 shrimp(0.32 ± 0.00 g) per replicate were fed four times a day for 8 weeks. Dietary Hyp supplementation had little effects on growth performance, but increased the contents of Hyp, prolyl 4-hydroxylases(P4Hs), and collagen. The meat yield, springiness, hardness,chewiness, and cohesiveness of muscle were the highest in the LF4 group among the low fishmeal groups(P quality of L. vannamei.
