Abstract

Beef is one of the favorite red meats containing various essential nutrients. In the processed beef products, food additives are used for multiple purposes including preservation, moisture and texture re-tention, improvement of flavor and stability of color. The purpose of this study is to identify the food additives composition of halal and local-based commercially processed beef products based on the label of the products and the Indonesian regulations. There were 40 various commercially processed beef pro-ducts assessed in this study. The food additives that were observed were flavor enhancers, preservatives, stabilizers, antioxidants, acidity regulators, and colorants. The types of food additives used in beef sausage products were stabilizers (30.00%), preservatives (25.56%), flavor enhancers (15.56%), colorants (14.44%), antioxidants (13.33%) and acidity regulator (1.11%). In beef balls products there were stabilizers (50.00%), flavor enhancers (20.00%), preservatives (15.00%), antioxidants, acidity regulators and co-lorants (5.00% each). The additives in beef burgers products include stabilizers (29.73%), preservatives (24.32%), colorants (21.62%), flavor enhancers (13.51%), antioxidants and acidity regulators (5.41% each). Corned beef products contain preservatives (32.00%), flavor enhancers and antioxidants (24.00% each), and stabilizers (20.00%). Additionally, smoked beef products use preservatives (50.00%), stabilizers (37.50%) and antioxidants (12.50%). The only food additives used in beef floss products was flavor enhancer (100%). The study suggests that Government Regulations on food additives should be reconsidered. Although the additives are still allowed in Indonesian regulations at the present, food additives of which are included in the list of carcinogenic agents shall be limited or even avoided. Future research to find safer alternatives for those food additives is recommended.

Abstract

Antioxidant plays an important role in keeping the body health. Antioxidant is needed to prevent the occurrence of oxidative stress, which causes of various degenerative diseases. Betacyanin in the dragon fruit peel takes part in antioxidant activity. The research is conducted using the central composite design (CCD) of the response surface methodology (RSM). This research aims to optimize the initial treatment condition by applying natrium metabisulfite immersion and drying on the dried dragon fruit peel. Three design composite factors used are natrium metabisulfite concentration (X1: 0.2-0.4%), drying temperature (X2: 65-75°C), and drying duration (X3: 4-5 hours) with betacyanin content (Y1) and antioxidant activity (Y2) as the response. A quadratic model is a method chosen for this research. The surface response showed the natrium metabisulfite concentration, temperature, and drying duration had signifi-cant effects on the betacyanin content and antioxidant activity. The most optimum condition of initial treatment is showed by immersion in 0.23% natrium metabisulfite and drying temperature of 70°C for 4.5 hours which resulted in 44.07 mg/100 g of betacyanin concentration and 50.56% antioxidant activity.

Abstract

Milk bioactive peptides are derivative of milk protein produced either through enzymatic activity, digestive processes, or fermentation, that give functional properties. The study aimed to obtain bioactive peptides fraction derived from goat’s milk casein through hydrolysis by papain, analyze the profiles of protein and peptides, and also test the antioxidative activity. The casein isolate was hydrolyzed by papain in a ratio of 100: 0.5 (v/v) at pH 7.0 and 50ºC. Analysis of protein concentration was carried out by the Bradford method and protein profile by SDS-PAGE. Antioxidant assay was carried out by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. A 1,000 ppm ascorbic acid solution was used as positive control. Peptide fractionation was done by membrane filtration with a cut off of 10 kD and 30 kDa. The protein concentration of casein hydrolysates decreased significantly after hydrolysis process with papain. The electrophoresis results showed six protein bands in casein with molecular weight of 7-33 kDa. After the hydrolysis process, all hydrolysates only contained two protein bands with molecular weights of 8 and 5 kDa. The hydrolysis process increased the antioxidant activity of the casein. P0 and P2 hydrolysates had the highest antioxidant activity, and fractions with the highest antioxidant activity were fraction <10 kDa from P0 hydrolysate at 67.89% and 10-30 kDa from P2 hydrolysate at 73.82%. Molecular weight and hydrolysis time affected the antioxidant activity of the hydrolysates. Peptides below 30 kDa have antioxidant activity, whereas those above 30 kDa do not have any antioxidant activity. The antioxidant activity of the peptides decreases upon hydrolysis for more then 2 minutes.

Abstract

Lactic acid bacteria (LAB) are the main group of probiotic bacteria that widely used in fruit juice fermentation products. Fruit juice contains antioxidants that can prevent free radicals. The objective of this study was to identify LAB isolated from pineapple juice that possess probiotic properties and to analyze the antioxidant activity of pineapple juice after being fermented with the LAB. LAB isolates from pineapple juice were evaluated for their probiotic properties (tolerance to acidic conditions and bile salts, antimicrobial activity against pathogenic bacteria, and sensitivity to antibiotics) and their adherence properties (autoaggregation, coaggregation, and hydrophobicity). The best isolates obtained are then inoculated into pineapple juice. From 5 types of pineapple juice, 5 isolates with LAB characteristics were obtained, i.e NHC6, NHC7, NHC8, NHC9, and NPC1. Isolate NHC6 had a good tolerance to acidic conditions (pH 2) and 0,5% bile salt, had antimicrobial activity, was sensitive to ampicillin, showed the best adherance properties and was identified as Lactobacillus plantarum. L. plantarum NHC6 was then added to pineapple juice. Addition of L. plantarum NHC6 to pineapple juice reduced the ᵒBrix and pH values during incubation. After 24 hours of incubation, the antioxidant activity was 89,05%, with LAB growth of 8,33 log CFU/mL, thus 24 hours incubation was considered the best fermentation time for pineapple juice.

Abstract

De Man Rogose and Sharpe (MRS) growth medium is a specific growth medium for lactic acid bacteria (LAB) but has a relatively expensive price. This can be overcome by making alternative media from waste materials. This study used Lactobacilus bulgaricus to represent LAB analyzed for growth. The research aims to formulate alternative media from the waste of cassava peels, banana peels, and tofu whey; determine the best formulation based on the growth parameters of L. bulgaricus; apply the L. bulgaricus in soygurt making and analyze the quality of the resulting yogurt. The results showed the composition of cassava peel: banana peel (75:25 w/w) with the addition of urea 1.5% as the best formu-lation. This formula yields a total LAB of 8.6x106 CFU/mL. The total LAB in the alternative medium was higher than that in MRS control at 1.7x106 CFU/mL. Soygurt produced from LAB as a result of growth from the best media [cassava peel+banana peel (75:25) with the addition of 1.5% urea] resulted in a fat content of 0.9%, total titrated acid 0.6%, protein 8.1 %, pH 4.7, viscosity 14.2 dPas, total dissolved solids 9.7°Brix, brightness (L) 64.3, and yellow-blue (b +) 10.1. These fat content, total titrated acid, and protein are in accordance with SNI for yogurt 2981: 2009.

Abstract

Bananas are known to contain fiber and vitamins essential for human body. Thus, the ability to detect these of vitamin in bananas is crucial. Information in the vitamin content of can affect procedures for harverst and post-harvest process. Methods to determine the nutrition content of foods are usually carried out using High Performance Liquid Chromatography (HPLC). However, this method requires complex sample preparation and chemical reaction processes. Due to this weakness, alternative techniques are needed to detect vitamin in simple ways. In this study, a simple, easy and fast methods to determine the vitamin content of banana was developed. Using reflectance and photoluminence spectroscopy, the vitamin of bananas from five different species were able to be identified. From the reflectance spectra results, two peaks were observed, the first peak at a wavelength of 325 nm is the absorption peak of vitamin B6 and the second peak at 450 nm is the absorption peak of vitamin B12. From the photoluminence spectra using excitation wavelength at 325 nm, an emission peak was found at wavelength 450 nm which is the peak emission from vitamin B6. These results proved that by using the methods proposed, the detection of vitamins in bananas can be done in an easy and simple ways.

Abstract

Moringa (Moringa oleifera) leaves are rich in minerals, vitamins and other essential phytochemicals. This study evaluated the effect of addition skim milk powder levels to the physicochemical, microbiology, antibacterial, and antioxidant properties of probiotic drink based on Moringa leaves juices. The probiotic drink was fermented by Lactobacillus casei FNCC 00090 with different level of skim milk powder (0, 3, 5, and 7%). The results showed that supplementation skim milk powders significantly affected the color of the probiotic product. The higher level of skim milk powders the lighter, greener, and more yellow (P<0.05). The higher concentration of skim milk affected the higher of pH and lactic acid content. The amount of probiotic among the treatment was not significantly different. The addition 7% skim milk powder produced the highest protein content, antibacterial activity, phenolic content, and antioxidant activity. Protein content of the best product was 2.65%, antibacterial activity: 14.50±1.80 mm (zone inhibition of .E coli) and 35.33±4.16c mm (zone inhibition of S. aureus), phenolic content 0.2410±0.0054 mg equivalent galic acid/ml sample and antioxidant activity 75.18±1.45%. The probiotics drink based on Moringa leaves juices has the potential to be developed as a functional drink.

Abstract

Plant leaves are the primary source of natural colorants for food, mainly due to their chlorophyll content. However, the plant types and the degree of leaf maturity determine the quality and quantity of the chlorophyll. This study aimed to determine the best maturity level of pandan (Pandanus amaryllifolius Roxb.) leaves that serves as potential source of chlorophyll for natural food colorants. Eighty three pandan plants obtained from six different farming locations in Bantul Regency, Yogyakarta, Indonesia were used as samples. The leaves were grouped into four levels of maturity using descriptive statistics based on their morphology, anatomy, color, and chlorophyll contents. The results showed that the average number of leaves ranged from 20-24 leaves per plant (at 95% confidence interval), and 96.4% of the plant had a maximum of 24 leaves. The leaf maturity was grouped into (1) young, (2) medium, (3) mature, and (4) over mature, corresponding to leaf number 1-6, 7-12, 13-18, and 19-24, respectively. The higher the leaf maturity, the higher the chlorophyll content. However, the over mature leaves were only slightly different from the mature ones. In addition, pandan leaves have specific flavor and contain carotenoid, phenolic, and flavonoid substances. Anatomically, the mesophyll’s size was greatest in the mature leaves, while the size of chloroplast was not significantly different from medium to over mature leaves. Based on the chlorophyll content and mesophyll size, it was concluded that mature pandan leaves were the best source of chlorophyll, containing chlorophyll of 623.08 mg/100 g dry weight (DW).
