Abstract

Hazard analysis and critical control point (HACCP) is a preventive system to ensure food safety. This enables product protection and error correction, reduces costs due to quality defects and reduces overcontrol of the final product. Collecting data using in-depth interviews, field observations, and study of documents owned by the research object. The HACCP system is applied to the noni juice production line in UD Manjur Makmur Lumajang. this small industry is seeking marketing approval from the BPOM (Food and Drug Supervisory Agency). Therefore, in order to follow the HACCP concept and ensure the safety of the food produced, some changes are required in the production process. Determination of critical control points (CCP) has focused on activities that are considered critical to pose a hazard, critical limits at each critical control point have also been determined The main hazards found were in sorting, seal opening and pouring in a press. The application of the HACCP principle will enable more accurate control of the noni juice production process.

Abstract

Black mulberry (Morus nigra L.) and canistel (Pouteria campechiana) are classified as fruit commodities that are still not optimal in their utilization. Based on their sensory and nutritional characteristics, they have potential to be processed into products for a longer shelf life and more valuable. The purpose of this study was to determine the optimal formula for a mixed fruit juice product made from black mulberry and canistel in terms of chemical, physical and sensory characteristics. The optimization formula was analyzed by Design Expert software ver.11 and through the Mixture D-Optimal method. The independent variables in this study are black mulberry puree, canistel puree, and sucrose. The dependent variables were 0.05% sodium benzoate and a mixture of CMC and sodium alginate 0.25% with a ratio of CMC: sodium alginate 1:1. The chemical parameters analyzed consisted of anthocyanin, beta carotene, vitamin C, and antioxidant activity. The physical parameters consisted of viscosity and sensory parameters consisted of flavor, sweet taste, and sour taste. The results obtained that the optimal formulation was based on the highest desirability value from the results of the analysis using the Design Expert program and the value was 0.807. The optimal formula for mixed fruit juices was black mulberry puree 53.356%, canistel puree 35.252%, and sucrose 11.092%.

Abstract

The brown alga has bioactive alginate and fucoidan, a potential for raw materials the biorefinery industry with core processing of fucoidan and alginate extraction. The research on sequential biorefinery of fucoidan and alginate was conducted in conventional and hydrothermal methods using a smart pressure-cooker, but the yield of fucoidan is low. The improvement was carried out by extracting fucoidan and alginate using microwave-assisted extraction (MAE). This study aimed to obtain the MAE processing conditions that produced the maximum yield of fucoidan and alginate. The factorial design of 2k was used to determine the effect of MAE processing conditions, i.e. temperature, time, and alga/water ratio on fucoidan and alginate yields. The parameters observed were fucoidan and alginate yield. Data analysis and prediction of first-order model and model accuracy was a regression modelling using a design expert program. The result showed that the elevate of temperature MAE processing to 80 oC,for 20 minutes, and alga/water ratio of 2:20 (w/v) increased fucoidan (4.5%) and alginate (40.6%) yield, but it decreased the yield at 100 oC, for 30 minute, and alga/water ratio of 3:30 (w/v). The equation of the first-order model was quadratic, by wich the model test in curvature was found significant at α=0.05. The MAE sequential biorefinery extraction improved fucoidan and alginate yield and had a potential efficiency for commercialization. The maximum response of fucoidan and alginate yield was obtained from a MAE sequential biorefinery at 80 oC,for 20 minutes,and alga/water ratio 2:20 (w/v); further research is needed to optimizing the process.

Abstract

Along with raising public awareness about health and increasing yogurt consumption .Fermented dairy products are considered beneficial foods for the health of human beings. One of them is yogurt which is a healthy drink made from milk with fermentation processing. The research aimed to analysis of antioxidant activity, vitamin C, and Lactic Acid of yogurt made from cow and goat milk. This study is a pure experimental study using a completely randomized design research, using 2 groups of samples, namely the sample with the electric shock processing method and the sample with conventional processing with 3 repetitions. The data obtained will be presented in tabular form and will be checked using the One Way Anova test. If there are differences, the test will continue with the Ducan test. Based on the results of the research analysis of antioxidant activity, vitamin C and lactic acid in goat's milk yogurt and cow's milk with differences in processing, namely the electric shock method and the conventional method had a statistically significant difference, namely with a p-value (0.00) where the value was ≤ α (0.05) which means that there is a significant difference in the average value of antioxidant activity, vitamin C and lactic acid in each sample. In this study it can be concluded that there are significant differences in the four samples. The best value in this study was found in goat milk yogurt with the electric shock method and the lowest value was found in conventional cow's milk yogurt in each analysis carried out, namely the analysis of antioxidant activity, levels of Vitamin C and lactic acid.

Abstract

Making nuggets by replacing meat with red beans can be used as a variant of nuggets for vegetarian consumption. Red beans have hard skin, so it is necessary to know the most appropriate cooking method to produce quality nuggets. The use of whole wheat flour as a binder aims to increase the fiber and protein content of the product. The purpose of this study was to determine the proportion of red beans and whole wheat flour as well as to show how to cook red beans for the quality of the nugget produced. This study used a factorial randomized block design (RAK) the first factor was the proportion of red beans and wheat flour (K), namely K1 (60%:40%), K2 (50%:50%), K3 (40%:60%). The second factor was the red beans cooking process (P), namely P1 (boiling) and P2 (steaming). The results showed that there was no interaction in all treatments. The treatment of the proportion of red beans and whole wheat flour had no significant effect on all parameters, while the treatment of red bean cooking affected the parameters of water content, ash, and carbohydrates. The results of the organoleptic test had a significant effect on taste, aroma, texture, and color. K3P2 treatment (proportion of red beans: 40%: 60% whole wheat flour and steaming) became the selected treatment with parameters water content 49.09%, ash content 1.85%, protein content 10.62 %, fat content 2.90%, carbohydrate content 35.53% and total preference for taste 63.3%, aroma 53.3%, texture 43.3% and color 63.4%.

Abstract

Guava (Psidium guajava) is a fruit that may be used as raw material for probiotic drinks. Guava contains fructose, and glucose which are used by lactic acid bacteria during the fermentation process. Use guava as the basic ingredient of probiotic drinks can increase the selling value of guava. The production of guava probiotics involves the bacterium Lactobacillus casei FNCC 0090 as a probiotic agent. This study aimed to determine the effect of fermentation time and type of Psidium guajava fruit on the characteristics of probiotic drink from guava. This study used a Randomized Complete Block Design (RCBD) with a factorial pattern with two factors, factor I was the time of fermentation (20, 24, 28 hours) and factor II was the type of fruit (red guava, white guava, crystal guava). The data obtained were analyzed using ANOVA and if there was a significant difference between treatments, it was continued by further testing at 5% DMRT level. Crystal guava juice probiotic drink fermented for 28 hours was the best treatment, with the resulting physicochemical characteristics, namely pH 3.3; total BAL 9.09 log CFU/ml, total acid 0.89%, total sugar 5.38%, vitamin C content 152.24 mg. The resulting organoleptic properties include color, aroma, taste, overall 3.4 (slightly like), 3.65 (slightly like), 4.55 (like), 3.60 (slightly like).
