Mayonnaise is the most favorite product that made from yolk and vegetable oil so it contain of 70-80% fat. The risk of high fat intake is deteriorating health so the percentage oil on mayonnaise have to decrease as reduced fat mayonnaise (RFM). Virgin Coconut Oil (VCO) is one of the various type vegetable oil that can used to make mayonnaise, and there have been several reports describing health benefit. This study was to determine the best percentage of the VCO based on emulsion stability, antioxidant and color L,a,b. The method used experimental laboratory and Completely Randomized Design (CRD) with fourth treatments and fourth replication. It consisted using VCO 70%, 60%, 50% and 40%. The result of this research gave significantly effect (P<0.01) on emulsion of stability, antioxidant and color test. The conclusion of this research was best formulation of RFM using VCO based emulsion stability, antioxidant and color test is 60% it was 80.50±0.57; and 20.65±0.55.

Food additives had been used to prevent and inhibit the growth of microorganisms and extend shelf life of food. Based on the safety of their used, it has an impact such as microorganism resistance to synthetic antimicrobials. This encourages the development of antimicrobials derived from natural ingredients, especially from milk. The bioactive components of milk protein have not always existed in their natural state, including precursors or peptides that will only be active if they have been hydrolyzed in vitro from their natural proteins. Hydrolysis of milk protein can be carried out using proteolytic enzymes from various sources, including protease extracted from Bacillus lincheniformis. This study used different concentrations of the protease extracted from Bacillus lincheniformis (0.5%, 1% and 1.5%) to produce hydrolyzate which has antibacterial activity in terms of protein content, SDS PAGE profile and the size of the inhibition zone (disc method). The results showed that the best activity of the whey hydrolyzed on Gram-negative Escherichia coli was 1% concentration of protease enzyme. In comparison, Gram positive Staphylococcus aureus can be inhibited with 0.5% concentration of protease enzyme.

Goat milk kefir (GMK) refers to fermented products, generated through fermenting milk with microbial culture called kefir grains. Prior studies have reported the changes in kefir quality properties during aging process in which fermentation continues, resulting in changes of the peptide content. This research aims to investigate the effect of aging time on GMK–peptide characteristics to inhibite triglyceride syntheses on cells model of 3T3-L1. In this study, GMK were stored at 4 ± 1 oC for 0, 2, 4, 6 and 8 weeks, respectively. The protein profile was characterizedby implementing SDS-PAGE. The result of experiment indicated no protein degradation during the 6 weeks of aging period particularly for high molecular weight at 84 kDa, 80 kDa and 65 kDa. The GMK-supernatant from 8 weeks storage was performed by applying ultrafiltration membrane cut off < 30 kDa (UFC8 030.08). GMK-filtrate fractions (GMK-peptide) was collected as peptides. After 8 weeks of aging period, kefir protein profile was found to consist of peptide fractions and amino acid. The proteolytic activity of kefir grain increased linearly along with aging time (0-8 weeks). During aging period, the proteolytic activity of grain kefir released peptides and amino acid. In particular, the antioxidant activities were found significantly different (p<0.05) during aging periods. The antioxidant activities of GMK-peptide increased along with the elevating peptide concentration, from 3.30 % to 55.73%, with derivate by GMK-peptides of 2.75 – 10.39 mg/ml. Obesity associated with adipocyte hypertrophy occurred when TG accumulation.GMK-peptide of 100 mg/ml indicated the lowest TG level (2.00 ± 0.03 mg/dl). This finding was in line with the inhibition of TG synthesis (61.14 ± 3.26 %). However, GMK-peptide contained antioxidant potency due to may be corelated with decreasing TG synthesis.The study thus suggested the important role of kefir to prolong aging in generating higher peptide bioactive as antioxidant and inhibition of TG synthesis of cell model of 3T3-L1

Milk production is intended for human consumption; hence preservation technology is required while maintaining the sensory and nutritional attributes. Some of technologies applied in milk are the use of pre-heating combined with pulsed electric fields (PEF) exposure. The aim of this study was to examine the effect of combination food preservation techniques using pre-heating and PEF with various conditions. The raw milk first received the pre-heating treatment at 70 ËšC, followed by PEF exposure. A completely randomized design (CDR) was applied in this research. It used two factors, namely factor I (pre-heating duration: 10, 20, and 30 minutes), and factor II (PEF exposure duration: 2, 4, and 6 minutes) with three replications, resulting in nine (9) treatments. The results reveal that there was a bacterial reduction within the range of 0.70-1.06 log CFU/mL. Besides, the increasing duration of pre-heating combined with PEF exposure decrease the values of viscosity, emulsion stability, and lightness of raw milk samples. Moreover, the most effective treatment observed in the raw milk-treated with pre-heating of 10 minutes and PEF of 2 minutes, with the level of TPC, viscosity, emulsion stability, and lightness of 1.88 log CFU/mL, 14.65 cP, and 95.65%, respectively

The addition of red ginger in the making of rendang was expected to increase antioxidants to prevent rancidity and increase the shelf life of rendang. This study aimed to analyze the physicochemical, organoleptic and antioxidant activity of beef rendang with the addition of red ginger at different levels based weight of meat (0%, 15%, and 30%). The tested rendang was stored in a tightly closed jar and left at room temperature. The results showed that the interaction of the addition of red ginger and storage period had a significant effect (p<0.05) on the pH value, water activity, moisture, protein content, TBARS value, and antioxidant activity, but has no significant effect on ash content, fat content, and tenderness. Ash and fat content as well as tenderness of beef rendang added red ginger were not different from beef rendang not added red ginger (control). Based on sensory test the addition of red ginger did not affect the preference of the panelists. The addition of red ginger to the manufacture of beef rendang has a positive effect on physicochemical characteristics and increases antioxidant activity. Generally, red ginger addition as much as 30% resulted the best result.

Red palm olein, which is rich in β carotene, has the potential as an animal fat replacer for the formulation of healthy processed meat products. However, it is mainly composed of saturated fatty acid, which should be reduced by combining it with unsaturated fatty acid-rich vegetable oil. Canola oil was mixed with red palm olein in order to get the benefits from both. The formulation of an emulsion gel made up of red palm olein and canola oil at 30/70 (w/w) was optimized using a response surface methodology. Soy protein isolate (SPI), mono and diglycerides of fatty acids (emulsifier E471, EMS), and inulin (INL) were selected as stabilizer and emulsifier in aqueous phase. Based on formula optimization and validation of gel emulsion ability in the comminuted meat model system, it was concluded that the addition levels of SPI, EMS, and INL required to form gel emulsions with optimal ability to produce comminuted meat products were 5.33%, 0.53% and 3.98% (w/w), respectively.

The purpose of this research was to determine the best ratio of whey protein isolate (WPI) for encapsulation of black pepper (Piper nigrum) essential oil (BPEO) on ultrasound-assisted emulsion. O/W emulsion was made from the oil phase from BPEO and corn oil (30:70) and the aqueous phase was made from the liquid modified glucomannan. The effect of WPI was investigated at different ratios (T0= 0%, T1= 2%, T2= 4%, T3= 6%,). BPEO emulsion was prepared using an ultrasonication method with the intention for produce nanoemulsion. The method of this research was an experiment with a Completely Randomized Design (CRD) by using four treatments and three replications, then continued by Duncan Multiple Range Test (DMRT). The physical characteristics were observed by viscosity and optical microscope. DPPH scavenging activity was used to know the effect of encapsulation on antioxidant activities. The Antibacterial activity was evaluated by the Kirby Bauer method with E. coli as the pathogen bacteria and L. casei as the probiotic bacteria. The increase ratio of WPI influences morphology. Different ratio of WPI gave a highly significant effects (p<0.01) on the viscosity and antioxidant, and gave no significant effects (p>0.05) on the inhibition diameter zone for E. coli and L. casei. Based on its physical characteristic, antioxidant activity, and antibacterial properties, it can be concluded that WPI can protect the BPEO by stabilizing O/W emulsion and may have the potential to be used as an alternative natural antioxidant and antibacterial additive in many food applications.

Manuka and forest honeys are types of honeys that are widely consumed because for their antioxidant properties. In this study, the properties of forets and manuka honey and the use of honey as a herbal drink with the addition of Qusthul hindi and turmeric were analyzed. The addition of Qusthul hindi (0,125 g and 0,375 g) and turmeric (0,125 g and 0,375 g) is given in two formulations. This study was conducted in two phase, namely analyzing the characteristics of manuka and forest honey and preparing herbal drinks to then analyzing their properties. The results showed that the properties of forest honey do not meet the standards for the variables of pH, HMF value, and diastase enzyme activity, while Manuka honey meets the standards only for variables of moisture, HMF value, and diastase enzyme activity. The addition of Qusthul hindi and turmeric to herbal drinks results in an increase in pH, DPPH inhibitoty activity, and antioxidant capacity, as well as a decrease of water content, but is not sensory evaluated because the addition of spices causes changes in taste and appearance.

This research aims to determine the quantitative characteristics of Brahman cross heifer cattle's carcass and wholesale cut at different age levels. The number of heifer cattle taken as samples was 104 heifer. The research method used is a case study with the selection of locations by purpose sampling. Direct observation is used to obtain information on age, slaughter weight, carcass weight, wholesale cut weight, and parts thereof (primary, secondary, and manufacturing cut). The data obtained were then analyzed by analysis of variance (ANOVA). If there was a significant difference, it is followed by a further test of the Least Significant Difference (LSD). The results showed that the age levels in slaughter had a significant effect (P<0.05) on the slaughter weight, fresh carcass weight and wilted carcass weight, but had no effect on the percentage of carcass and wholesale cut. The older the age of cattle and the longer the cattle are raised, the higher their body weight will affect the slaughter weight produced, and the higher the slaughter weight, the higher the carcass weight made. Average slaughter weight at different age by Permanent Incisor (PI): PI0 (<18 months), PI2 (18-24 months) and PI4 (24- 36 months). While the average percentage of heifer carcass at different age levels was relatively the same (52,71% : 53,04% : 53.10%). The weight and rate of wholesale cut and its parts are also somewhat the same. The research results show that the slaughter age affects the slaughter weight and carcass weight but not dressing percentage and wholesale cut weight. Brahman cross heifer cattle at PI4 produced optimal carcass weight and wholesale cut.
