Reduced fat mayonnaise products have an unstability of the emulsion, so a stabilizer is needed to improve quality of mayonnaise. Apple peel flour can be used as a stabilizer to improve the quality of mayonnaise. The materials used in this study were vegetable oil, egg yolk, vinegar, apple peel flour and other optional ingredients. The research treatment was without the addition of apple peel flour as a control, the use of 1%, 2% and 3% apple peel flour. The objective of this research was to determine the best percentage of apple peel flour as a stabilizer in reduced fat mayonnaise. The research method used is a laboratory experiment method. The design used was a completely randomized design with 4 treatments and 4 replications. Analysis of variance was used to analyze the resulting data, if there was a difference in the effect, it was continued with Duncan's Multiple Range Test.This study resulted that the use of apple peel flour used as a stabilizer resulted gave highly significant difference in reduced fat mayonnaise. The average acidity is 0.66-0.90, the emulsion stability is 96.92- 99.18%, the antioxidant activity is 8.37-19.38%, the carbohydrate content is 2.63-5.81% and ash by 1.72-1.92%. It could be concluded that the use of 3% apple peel flour can produce the best quality reduced fat mayonnaise product and is close to the characteristics of full fat mayonnaise.

The experiment was conducted to evaluate the production performance and egg quality of laying hens supplemented with phytobiotics and magnetized drinking water. This experiment used 2700 gauss level in Magnetized Drinking Water (MDW). The phytobiotics had two form: the non-encapsulated phytobiotics (PTO) and encapsulated phytobiotics (EPTO). There were untreated water (control) and the treated water (MDW, PTO, PTO+MDW, EPTO, EPTO+MDW). The treatments were presented by 0.6% for each treatment. The result showed highly significant (p<0.01) improvement on feed conversion ratio (FCR) but no significant effect on other production performance variables including feed intake, hen day production (HDP), egg mass, and income over feed cost (IOFC). The results indicated a highly significant improvement (p<0.01) on egg weight and yolk cholesterol. There were no significant effects on shape index (SI), shell weight, shell thickness, Haugh unit (HU), albumen height, yolk weight, yolk index (YI), and yolk color of egg quality variables. It was concluded that the encapsulated form (EPTO and EPTO+MDW) had the best improvement on FCR and yolk cholesterol, on another hand the non-encapsulated form (PTO and PTO+MDW) increased the egg weight of laying hens
本试验旨在评价添加植物制剂和磁化饮用水对蛋鸡生产性能和蛋品质的影响。本实验采用2700高斯水平磁化饮用水(MDW)。植物制剂有两种形式:非包封植物制剂(PTO)和包封植物制剂(EPTO)。分为未处理水(对照)和处理水(MDW、PTO、PTO+MDW、EPTO、EPTO+MDW)。每个治疗方案的呈现率为0.6%。结果表明:饲料系数(FCR)极显著(p<0.01)提高,采食量、产蛋量、产蛋量、饲料成本收入比(IOFC)等生产性能指标无显著影响。结果表明:鸡蛋重和蛋黄胆固醇极显著改善(p<0.01)。对蛋品质变量的形状指数(SI)、壳重、壳厚、哈夫单位(HU)、蛋白高度、蛋黄重、蛋黄指数(YI)和蛋黄颜色均无显著影响。综上所述,包封型(EPTO和EPTO+MDW)对FCR和蛋黄胆固醇的提高效果最好,非包封型(PTO和PTO+MDW)对蛋鸡蛋重的提高效果最好

The aim of this study was to evaluate the effect of ozone exposure to the physicochemical and microbial activity in dairy milk. The research material was fresh milk from dairy cows and ozone was produced by commercial ozone generator brand HANACO, production capacity up to 0.702 mg/min at 24-27ºC with oxygen source coming from ambient air in the nature. The experiment used ozone treatments for 0, 10, 20, and 30 min with variable of analysis such as density, protein, fat, electrical resistance, total plate count, and malondialdehyde which was analyzed using One Way Annova. The results showed that ozone treatment had no significant effect on the density, protein and fat in dairy milk, but had significant (P<0.05) effect on the electrical resistance, total plate count, and production of malondialdehyde. Electrical resistance and malondialdehyde were increased, while total plate count was decreased over time with the ozone exposure. Ozonation is possible to reducing yield loss on milk production that is caused by microbial activity without changing the physicochemical properties of dairy milk.
本研究的目的是评估臭氧暴露对牛奶中理化和微生物活性的影响。研究材料为奶牛鲜奶,臭氧由HANACO商用臭氧发生器产生,在24-27℃条件下,氧气来源为自然环境空气,臭氧生产能力可达0.702 mg/min。实验采用臭氧处理0、10、20和30 min,分析变量为密度、蛋白质、脂肪、电阻、总平板数和丙二醛,采用单向方差分析。结果表明,臭氧处理对乳中的密度、蛋白质和脂肪无显著影响,但对电阻、总平板数和丙二醛产量有显著影响(P<0.05)。电阻和丙二醛增加,而总板数随着臭氧暴露时间的推移而减少。臭氧化可以在不改变牛奶理化性质的情况下减少微生物活动对牛奶生产造成的产量损失。

Organic waste has high COD and BOD content, so it is dangerous if disposed of directly into the environment. Organic waste processing, such as waste from livestock manure and liquid tofu waste, requires a process that can reduce COD and BOD levels as well as produce valuable products. Anaerobic digestion method is the proper process to convert complex compounds in waste into simpler compounds with methanogenic bacteria into a renewable energy product, namely biogas. On the other hand, the anaerobic digestion process can reduce COD and BOD levels in the biogas formation process. This study uses raw materials such as cow manure and chicken manure, and liquid tofu waste. The variables that produced the largest biogas were those with a ratio of 70% cow dung, 15% chicken manure, and 15% tofu liquid waste with a total of 3,251.5 mL. Then, the COD and BOD levels decreased significantly with more than 98% COD removal, and more than 95% BOD removal in all variables at the end of the anaerobic digestion process.
有机废物的COD和BOD含量很高,如果直接排放到环境中是危险的。有机废物处理,如禽畜粪便和液态豆腐废物,需要一种既能降低COD和BOD水平,又能生产有价值产品的工艺。厌氧消化法是利用产甲烷细菌将废物中的复杂化合物转化为简单化合物,转化为可再生能源产品即沼气的适当过程。另一方面,厌氧消化过程可以降低沼气形成过程中的COD和BOD水平。本研究采用牛粪、鸡粪、豆腐渣等原料。产气量最大的变量为牛粪70%、鸡粪15%、豆腐废液15%,总量为3251.5 mL。然后,COD和BOD水平显著下降,COD去除率超过98%,厌氧消化结束时,所有变量的BOD去除率均超过95%。

This study aims to determine the antimicrobial activity of red fruit paste against Staphylococcus aureus FNCC-0047 and Eschericia coli FNCC-0091 by using ethanol and n-hexane as well as the total plate count value of the patty with red fruit paste added on different observations day. The concentration of paste extract for antimicrobial activity test was 6.25%, 12.5%, 25%, 50%. The calculation of the total value of the burger patty plate is calculated on the 3rd, 7th and 14th d with the red fruit paste content in the formula as much as 0%, 5%, 10%, 15%. The results showed that the fatty acids of red fruit paste were dominated by oleic acid and linoleic acid, which are unsaturated fatty acids and palmitic acid, which are saturated fatty acids. The yield of red fruit paste in n-hexane solvent was higher than ethanol solvent. There was a significant difference (P <0.05) from the use of different solvents to the mean clear zone of the two bacteria tested. The antibacterial activity shown by the ethanol extract and n-hexane extract of red fruit paste was in the inactive category at the 6.12% level, the moderate category at the 12.5% to 25% level and the strong category at the 50% level. There was a significant difference (P <0.05) from the total microbial value in each treatment where the higher the red fruit paste content in the patty, the lower the total microbial value found on each d of observation. The use of red fruit paste at a level of 10% to 15% can withstand the rate of microbial growth

A method to improve the physical quality of culled chicken meat is required due to the tough texture and faint color of culled chicken meat. High protein content in culled chicken meat makes it easy to experience quality degradation. One of the methods to maintain the quality of post-harvest chicken meat is using spices. Gelugur acid (Garnicia atroviridis) is a spice for cooking spice, sweets, herbs, deodorizing fresh fish, and even cleansing fish before it proceeds into the processing stage. This study aimed to determine the concentration of Garcinia atroviridis which is effective to improve the physical quality of culled chicken meat. This study used a randomized design with 4 treatments and 5 replications. The treatments consisted of T0: without marination using Garcinia atroviridis (as control), T1: marination in 50 g of Garcinia atroviridis + 1000 mL aquadest, T2: marination in 50 g of Garcinia atroviridis + 750 mL aquadest, T3: marination in 50 g of Garcinia atroviridis + 500 mL aquadest. The parameters were the physical quality of meat consisting of meat pH, water holding capacity, tenderness, cooking loss, drip loss and meat color. Based on the results of the study, Garcinia atroviridis marinade had significant effect (P <0.05) on the pH value of the meat, cooking loss, drip loss, tenderness, water holding capacity, and meat brightness. It was concluded that the marination of meat at concentration of 50 g of Garcinia atroviridis + 1000 mL aquadest (T1) was effective in maintaining the pH value, reducing meat drip loss, increasing water holding capacity, increasing tenderness, brightening the color of the meat and maintaining the freshness of the refined culled chicken meat. Marination of meat in concentration of 50 g Garcinia atroviridis + 750 mL aquadest (T2) was also effective in reducing cooking loss of culled chicken meat.
由于鸡的肉质较硬,颜色较淡,因此需要提高鸡的物理质量的方法。剔除的鸡肉蛋白质含量高,容易出现质量退化。保持收获后鸡肉质量的方法之一是使用香料。明胶酸(Garnicia atroviridis)是一种香料,用于烹饪香料,糖果,草药,除臭鲜鱼,甚至在进入加工阶段之前清洗鱼。本研究旨在确定能有效改善扑杀鸡肉物理品质的黄毒藤黄菌的浓度。本研究采用随机设计,4个处理,5个重复。处理分为T0:以黄毒藤为对照,不进行腌制,T1:用50 g黄毒藤浸泡+ 1000 mL水凝胶,T2:用50 g黄毒藤浸泡+ 750 mL水凝胶,T3:用50 g黄毒藤浸泡+ 500 mL水凝胶。实验参数为肉的物理品质,包括肉的pH值、保水能力、嫩度、蒸煮损失、滴漏损失和肉的颜色。从研究结果来看,黄毒藤腌制液对肉的pH值、蒸煮损失、滴水损失、嫩度、保水能力和肉的亮度有显著影响(P <0.05)。综上所述,以50 g Garcinia atroviridis + 1000 mL aquadest (T1)的浓度进行肉品腌制,可有效保持精加工鸡肉的pH值,减少肉品滴漏损失,提高保水能力,增加嫩度,使肉品色泽鲜艳,保持肉品新鲜度。以50 g Garcinia atroviridis + 750 mL aquadest (T2)的浓度浸泡鸡肉也能有效减少精选鸡肉的蒸煮损失。

Red beetroot is rich in phenolic acids and betalain as natural food-coloring agents. Freeze-dried red beetroot that ground into powder can be used as a source of natural coloring to substitute the use of synthetic food color additives as well as filler to substitute tapioca. This study evaluates the function of red beetroot powder not only as filler but also as coloring agent on chicken sausage. Furthermore, its effects as filler (tapioca and beetroot) were also observed on the physical and sensory characteristics of the produced chicken sausage. The substitution of tapioca flour and beetroot powder in this study were 18:0, 17:1, 16:2, and 15:3 (%:%). Each treatment was consisted of three replications. The examined physical properties include pH, water-holding capacity (WHC) and sensory properties. The study found that WHC, color, texture profile and sensory properties were influenced by the increasing level of beetroot flour ratio, while different ratios had no effect on the pH. Chicken sausages made with higher ratio of beetroot flour had good acceptability on flavor and color. The conclusions of this study were substitution tapioca with 2% beetroot powder influenced physical quality (water holding capacity and tenderness) and sensory (color and flavor) of chicken sausage.
红甜菜根富含酚酸和甜菜素,是天然的食用着色剂。冷冻干燥的红甜菜根磨成粉末,可以作为天然色素的来源,以替代合成食品色素添加剂的使用,也可以作为替代木薯粉的填料。研究了红甜菜根粉在鸡肉香肠中的填料和着色剂作用。此外,还观察了木薯粉和甜菜根作为填料对鸡肉香肠的物理和感官特性的影响。木薯粉和甜菜根粉的替代率分别为18:0、17:1、16:2和15:3(%:%)。每个治疗包括三个重复。检测的物理性质包括pH值、持水量(WHC)和感官性质。研究发现,随着甜菜根粉比例的增加,肉重、颜色、质地轮廓和感官性能都受到影响,而不同比例的甜菜根粉对ph没有影响。甜菜根粉比例较高的鸡肉香肠在风味和颜色上都有较好的可接受性。研究结果表明,用2%甜菜根粉代替木薯粉对鸡肉香肠的物理品质(保水能力、嫩度)和感官品质(色、味)都有影响。

Hypercholesterolemia is a disease that is indicated by the increasing level of cholesterol in the body and also as one of the factors causing cardiovascular disease. An alternative that can be done to prevent hypercholesterolemia is by consuming fermented milk. Skim milk is fermented using probiotic of Lactobacillus acidophillus, Lactobacillus plantarum and Streptococcus thermophilus. The skimmed milk that has been fermented is then tested for total lactic acid bacteria, total acid, pH, and in vivo analysis for antihypercholesterolemia activity using animal model. In this study, the animal models used were male white rats which were grouped into three treatment groups, namely negative control, positive control, and fermented milk group. The result of the study shows that the total lactic acid bacteria, total acid and pH of fermented skim milk were 5.25 x10 9 CFU/ml ; 2.190% and pH 4.06, respectively. From the results, fermented milk with probiotics has the ability to reduce cholesterol levels in the blood of male white rats effectively in vivo.
