The diced chicken with mushroom was taken as the research object to investigate the differences in quality and protein digestion characteristics between traditional (TD) cooked and prefabricated (ST) product. The results showed that compared to TD cooked, the acceptability and flavor of sensory evaluation of ST product decreased significantly, while the taste and chewiness improved remarkably. In addition, the bound and immobilized water were found transferred to free water indicated the water holding capacity decreased and meat softened. The analysis of gas chromatography-mass spectrometry (GC-MS) indicated that hexal, octanal and volatile substances from spices were the key substances causing flavor differences between the two methods and could be further distinguished by the electronic nose and tongue. The results of digestion in vitro showed that the protein digestibility, release rate of peptide and free amino-acid in the ST product were higher than that in the TD cooked. The contents of α-helix and β-sheet decreased with the increase of digestion time in the two methods, while the α-helix content of the ST product was lower during the first 60 min of intestinal digestion than that in TD cooked. These findings give a new insight into the associations of processing methods with meat quality.

“…Products recovered from C. nippon are well known for its health promising properties, thus identified as valuable medicinal herbs at home and abroad. Its deer heart, deer blood, and antler blood are the hot spots for the development of plum deer resources in China in recent years [ 4 ]. Deer hearts mostly refers to the heart of plum deer or horse deer [ 5 ], which is rich in a variety of amino acids, vitamins, peptide proteins, and other substances and is a good medicine to enhance the metabolic function of human body and improve cardiovascular diseases and nervous system functions [ 6 ].…”

Peptides are widely used as natural bio-small molecules because of their various pharmacological activities such as enhancing immunity, promoting wound healing, and improving inflammation. Alcoholic heart injury has become one of the major health problems worldwide, and alcohol consumption is now the main cause of alcoholic cardiomyopathy. In this study, deer heart peptides were extracted from deer hearts by enzymatic digestion and the antioxidant activity of deer heart peptides extracted at different times was evaluated by three in vitro antioxidant methods, and the active peptide with the best enzymatic effect has been selected for in vivo animal experiments. The anti-inflammatory and antioxidant properties of deer heart enzymatic extracts were evaluated in in vivo experiments in mice. In this study, mice were orally gavaged with white wine (12 mL/kg body weight) to induce a mouse model of cardiac injury, while mice were orally administered a single dose of 100 mg/kg/bw and 200 mg/kg/bw of deer heart enzyme digest and were examined for body weight, dietary intake, water intake, and coat gloss, as well as for general behaviors, adverse effects, and mortality. Histology, serum, anti-inflammatory factors, and oxidative stress parameters were subsequently assessed. In all modeled mice, no four-way or any significant behavioral changes were observed in all groups, but in the modeled group, mice showed weight loss, decreased diet and water intake, and decreased cardiac index. For in vivo tests, the extract inhibited the anti-inflammatory activity with a significant decrease in inflammatory factors of TNF-α, IL-6, and IL-1β in cardiac tissues, a significant increase in serum levels of both CAT and SOD, an increase in MDA content, and a remarkable increase in the level of the marker CK in the cardiac myocardial enzyme profile. Significant improvement in myocardial disorders by deer heart peptide could be observed from heart tissue sections. The present study emphasizes the anti-inflammatory and antioxidant activity of deer heart peptide, an enzymatic digest of deer heart, which provides empirical as well as supportive role for the anti-inflammatory properties of traditional medicine.
