· 蛋白过瘤胃：与瘤胃蛋白质缩合沉淀，降低了饲料蛋白在瘤胃中的发酵与分解，有效提高反刍动物蛋白利用率。

· 安全无残留：天然植物提取，无耐药性，无配伍禁忌。

产品功效

· 有效收敛肠粘膜，抑制有害菌，减少猪腹泻、禽类水便症状

· 提高反刍动物过瘤胃蛋白质，减少氨气和甲烷产生，有效缓解反刍动物鼓胀病

Tannic acid, derived from natural plant extracts, has good anti-diarrhoeal, anti-bacterial, anti-oxidant and anti-parasitic effects, which can improve the growth performance of livestock and poultry, increase feed utilization, reduce the use of antibiotics and zinc oxide, and improve the overall health of animals and the safety of animal products.

Product characteristics

· Astringent anti-diarrhoea: astringent intestinal mucosa, condensation with intestinal mucosal protein to produce ellagic acid protein, forming a protective film on the intestinal epithelial cells, reducing water secretion; prolonging the residence time of surimi in the small intestine, enhancing water reabsorption, thus effectively reducing the incidence of diarrhoea.

· Bacterial and antioxidant: It has an inhibitory effect on Escherichia coli, Salmonella enteritidis, Clostridium perfringens, Staphylococcus aureus, Campylobacter jejuni and other pathogenic bacteria; the hydroxyl group of tannins is an excellent hydrogen donor, which can effectively scavenge free radicals and inhibit lipid peroxidation in blood plasma and tissues.

· Protein over the rumen: condensation and precipitation with rumen proteins, reducing the fermentation and decomposition of feed proteins in the rumen, effectively improving protein utilisation in ruminants.

· Safe and residue-free: natural plant extracts, no drug resistance, no contraindications.

Product efficacy

Effective astringent for intestinal mucosa, inhibits harmful bacteria, reduces diarrhoea in pigs and watery stools in poultry. Improves ruminant over-rumen protein, reduces ammonia and methane production, effectively relieves ruminant bulging disease, relieves heat stress, improves meat quality, extends shelf life, reduces faecal odour, reduces odour, improves the environment and reduces the use of antibiotics and zinc oxide.

The Effects of Tannins in Monogastric Animals with Special Reference to Alternative Feed Ingredients

2021年1月3日没有评论

饲用单宁酸Abstract: Over recent years, the monogastric animal industry has witnessed an increase in feed prices due to several factors, and this trend is likely to continue. The hike in feed prices is mostly due to extreme competition over commonly used conventional ingredients. For this trend to be subdued, alternative ingredients of both plant and animal origin need to be sourced. These types of ingredients are investigated with the aim of substituting all or some of the conventional compounds. However, alternative ingredients often have a double-edged sword effect, in that they can supply animals with the necessary nutrients although they contain antinutritional factors such as tannins. Tannins are complex secondary metabolites commonly present in the plant kingdom, known to bind with protein and make it unavailable; however, recently they have been proven to have the potential to replace conventional ingredients, in addition to their health benefits, particularly the control of zoonotic pathogens such as Salmonella. Thus, the purpose of this review is to (1) classify the types of tannins present in alternative feed ingredients, and (2) outline the effects and benefits of tannins in monogastric animals. Several processing methods have been reported to reduce tannins in diets for monogastric animals; furthermore, these need to be cost-effective. It can thus be concluded that the level of inclusion of tannins in diets will depend on the type of ingredient and the animal species.单宁酸

单宁酸具有抗氧化作用，是一种天然的防腐剂，能有效避免红酒被氧化变酸，使长期储存的红酒能保持最佳状态。最近的研究发现，单宁对预防和治疗心血管疾病有较好的效果。心脑血管疾病仍是威胁人类健康的头号杀手，所以中老年人坚持每天喝适量的葡萄酒进行自我保健是一个很好的方法。另外，现在很多年轻人工作压力大，精神压力大，很多人都处于亚健康状态。因此，年轻人最好也养成喝红酒的习惯，这样可以安抚神经，缓解压力。

单宁酸及其与不同有机氮化合物和酶的复杂相互作用:旧的范式与新的进展对比

2020年5月28日没有评论

单宁与蛋白质之间的相互作用已经研究了50多年，因为其独特的特性和在食品工业和药理学中的潜在用途。然而，随着单宁酸浓度对酶的调控以及与其他非蛋白氮化合物的潜在相互作用的新见解的提出，未来的研究还需要进行。应特别注意使用纯化和表征良好的单宁，因为植物提取物中多酚的化学成分和其他化合物的存在可能会显著影响单宁与氮化合物的相互作用。后续研究的目的应该是将这些结果推导到更复杂的、异质的、现实的体系中。总之，研究单宁酸与蛋白质之间的相互作用，以及其他有机化合物之间的相互作用的研究很可能会引起人们的极大关注，因为人们对多酚类化合物在人类健康和疾病治疗方面的普遍兴趣，同时也对其在饮料和食品工业中的作用产生了浓厚的兴趣。

Tannins and Their Complex Interaction with Different Organic Nitrogen Compounds and Enzymes: Old Paradigms versus Recent Advances

2020年5月28日没有评论

Interactions between tannins and proteins have been studied for more than 50 years, because of their unique characteristics and potential use in food industry and pharmacology. However, with the new insights regarding regulation of enzymes by tannin concentration and the potential interaction with other non‐protein N compounds, future studies are needed. Special attention should be paid to the use of well‐purified and characterized tannins, because the chemistry of polyphenols and the presence of other compounds in plant extracts may significantly affect tannin interactions with N compounds. Follow‐up studies should aim to extrapolate these results to more complex, heterogenic, realistic systems. In conclusion, studies investigating the interactions between tannins and proteins, but also other organic compounds, are likely to attract significant attention due to the general interest in polyphenols with regard to human health and disease treatment, but also their role in the beverage and food industry.
