[目的]以牛奶、板栗、抹茶为主要原料,探究板栗抹茶酸奶的加工工艺。[方法]通过单因素试验,确定抹茶、板栗浆、菌种和蔗糖的最佳添加量,采用四因素三水平进行正交试验,并以感官评价、酸度相结合为综合指标,得出最佳配方。[结果]板栗浆添加量30%,菌种接种量0.3%,抹茶添加量0.03%,蔗糖添加量6%,稳定剂添加量0.3%,在42 ℃发酵至发酵终点,再后熟24 h可得到组织细腻、口感良好的酸奶。此时的综合评分也最高,为89分,酸度为83 °T。[结论]该酸奶营养丰富,有良好的饮用价值和保健功能,为扩充市售酸奶的品种提供依据。 相似文献

The objective of this study was to determine the impact of ginger and/or thyme aqueous extracts administration on the growth rate, caecum activity, reproductive performance and semen quality of rabbits. A total of 24 V‐line male rabbits at the age of 12 weeks were divided randomly into four equal groups (6/each) until 24 weeks of age. Treatments were as follows: drinking fresh water and served as control (G1); drinking water supplemented with 100 mg/kg b. wt. of ginger aqueous extract (G2); drinking water supplemented with 50 mg/kg b. wt. of thyme aqueous extract (G3); drinking water supplemented with 100 mg/kg b. wt. of ginger aqueous extract plus 50 mg/kg b. wt. of thyme aqueous extract (G4). Administration of aqueous thyme extract with 50 mg/kg b. wt. improved (p < 0.001) feed intake and growth performance compared to control. The highest average daily gain (p < 0.001) was found for G3 rabbits followed by G4, G2 and G1 respectively. While the most efficient feed conversion ratio was found in G4. Group 3 and group 4 had significant (p < 0.05) positive effect on caecum pH, ammonia and TVFAs concentration. Data indicated that treated groups had hastened the age with heavier body weight, larger testicular size and higher testosterone level. Also, most semen characteristics (volume, progressive motility, sperm concentration and normal spermatozoa) were higher in treated groups compared with the control group. Furthermore, gathering of the spermatozoa in the lumen of the seminiferous tubules, expanded epithelial cells stature of the epididymis with stuffed lumens with sperms in treated groups. In conclusion, aqueous extracts of ginger and/or thyme can be used as a growth promoter for improving reproductive performance of V‐line male rabbits. 相似文献

To evaluate the effect of dietary dried fermented ginger (DFG) on intestinal villous histological alteration and growth performance, 64 Marshall Chunky male broilers were divided into four groups, each with four replicates of four chickens. Birds were fed the basal commercial mash diet supplemented with DFG at 0 (control), 5, 10 and 20 g/kg for 42 days. With increasing dietary DFG levels, feed intake tended to decrease and significantly decreased in the 20 g/kg DFG group (p < 0.05). Weight gain was higher in all the DFG groups, with the highest in the 10 g/kg DFG group (p < 0.05), resulting in an improved feed efficiency in all the DFG groups. Intestinal villus height, villus area, cell area and cell mitosis in all the intestinal segments were higher in all the DFG groups than in the control group. Protuberated cells and cell clusters were found in all the DFG groups, suggesting that the intestinal villi and cells might be hypertrophied. The present results indicate that dietary DFG can be used as a natural feed additive to induce broiler growth performance as a result of stimulation of morphological maturation and in consequence intestinal function. 相似文献

试验旨在探讨饲粮添加不同水平的生姜粉对蛋鸡生产性能和蛋品质的影响。选取27周龄罗曼褐壳蛋鸡120只,随机分为4组,每组设3个重复,每个重复10只。对照组饲喂基础饲粮,试验组分别添加0.5%、1.0%、1.5%的生姜粉。预饲期7 d,试验期4周。结果表明:饲粮中添加适量的生姜粉可以提高蛋鸡的平均日产蛋量和试验3~4周的产蛋率以及试验1~2周的平均蛋重(P<0.05)。饲粮中添加适量生姜粉能够提高鸡蛋的哈夫单位和蛋比重(P<0.05)。结果提示,饲粮中添加生姜粉可提高罗曼褐壳蛋鸡的生产性能和蛋品质,以1.0%生姜粉为最适添加量。 相似文献

选用1日龄健康土杂肉鸡300只进行饲养试验,研究生姜、喹乙醇对0—60日龄土杂肉鸡采食量、日增重、饲料增重比及成活率的影响,以评定生姜作为中药饲料添加剂的价值。实验完全随机抽取300只小鸡分成3组,整个实验期间,洛加生姜组的日增重、饲料增重比和成活率均明显高于对照组(P<0.05);采食量差异不显著(P>0.05),但有高于对照组的趋势。添加生姜组与添加喹乙醇组相比较,采食量、日增重、饲料增重比、成活率均无显著差异(P>0.05),但饲料增重比略低于喹乙醇组。血清胆固醇含量以添加生姜组最低,总蛋白含量最高。综合各项指标,饲料中添加1%生姜效果最好,具有明显的增强食欲、提高土杂肉鸡采食量和饲料转化率,促进生长的作用。 相似文献
