Abstract

Pregelatinized starch is a common type of physically modified starch with wide applications, especially in the food industry. This study aimed to obtain information about the effect of cooking temperature on the characteristics of pregelatinized sago starch and to obtain the best cooking temperature. The treatment in this study was variation in cooking temperature without pregelatinization (control), 50°C, 60°C, 70°C, 80°C, 90°C, and 100°C. Data obtained were statistically analyzed using Analysis of Variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) at a 5% level. The results showed that variations in pregelatinization temperature significantly affected all observed parameters. The best treatment was pregelatinization temperature 90°C, with moisture, amylose content, swelling power, starch solubility, WHC, and gelatinization degree of 13%; 24,94%; 16,90 g/g; 58,22%; 131,06%; and 42,17% respectively. The gelatinization profile of sago starch was selected with the respective viscosity values: peak 5473 cP, heat 1509 cP, breakdown 3964 cP, final 2964 cP, and setback 1419 cP.

Abstract

Red rosella is one of the beneficial plants with its flower petals that have a distinctly sour taste. Using rosella in water kefir can enrich its functionality and taste. Rosella water kefir has acidic characteristics derived from rosella and sugar substrates. Sugars such as sucrose in the production of water kefir act as a carbon source for the metabolism of water kefir grains. The higher the added sugar causes the total of good microbes and organic acids in water kefir products to increase, but too high sugar can cause the death of these good microbes so it also affects the nutritional content and taste of the product. Therefore, the best concentration of sugar is needed. This study aims to obtain the best sucrose concentration in producing the best physicochemical, microbiological, and organoleptic characteristics of rosella water kefir. This study used the addition of sucrose at concentrations of 6%, 9%, 12%, and 15% (w/v) with the parameters observed in physicochemical characteristics including total dissolved solids, biomass, CO2 content, and total acid, microbiological characteristics including total lactic acid bacteria and total microbes, and organoleptic characteristics including sweet taste, sour taste, soda sensation, and aroma. The results obtained in this study indicate that increasing the concentration of sucrose in rosella water kefir had a significant effect (p<0.05) on the physicochemical, microbiological, and organoleptic characteristics of sweet and sour tastes. The addition of 12% sucrose was the limit—tolerance for the addition of sugar in rosella water kefir which is also the best treatment.

Abstract

Analog rice is an alternative food to replace rice using sago, sorghum, or even corn with carbohydrate content near or exceeds the rice and the shape. Analog rice made from mocaf flour has a lower protein content than milled rice, so it is necessary to add soy flour which has 35.00% of protein content, sago flour which has 21.38% of amylose content, and Moringa leaves flour which has an antioxidant activity of 32.96%. Carrageenan is also added to the mixture as a binder. The aim of the study was to determine the effect of the proportions of composite flour (mocaf: sago: soybean: moringa leaves) with the addition of carrageenan on the characteristics of analog rice. Completely randomized factorial design was used in this study with the first factor proportion of mocaf : sago : soybean : moringa leaves flour such as  A (70 : 10 : 20 : 3.5gr), B (60 : 20 : 20 : 3.5 gr), and C (50 : 30 : 20 : 3.5gr) with the second factor the addition of carrageenan (2, 3 and 4%). The data were analyzed using Minitab V.17, with 5% DMRT (Duncan Multiple Range Test). The best results for analog rice were obtained from proportion A (70: 10: 20: 3.5 gr) with the addition of 3% carrageenan with characteristics 3.22% of moisture, 2.83% of ash, 145.33% of rehydration power, 106.25% of swelling volume and 12.5% of antioxidant activity, with organoleptic score 3.10 of taste, 3.55 of colour; 3.38 of flavor; and 3.10 of texture.

Abstract

The development of beta-carotene-rich MOCAF flour as a functional food aims to increase its nutritional content and functional properties as an antioxidant for health. The development of beta-carotene-rich MOCAF flour can be optimized through good fermentation methods, especially with the use of starter. This study aims to further analyze the effect of using a type of starter on the MOCAF characteristics of cassava species rich in beta-carotene through a comparison of several types of starter. In this study, three types of starter were used, namely the Bimo-CF starter, the Berhasil starter and the BRIN starter. The results showed that the use of starter during fermentation affected the physicochemical properties of MOCAF flour in the form of differences in solubility, increased viscosity and decreased syneresis. Scanning Electron Microscope (SEM) was used to analyze the microstrutural of MOCAF flour using starter during fermentation resulted in a more massive reshuffling of starch granules and causes changes in the structure of starch granules that become irregular round in shape with increasingly non-uniform sizes. NIR (Near infrared) and proximate analysis of the content of MOCAF flour, showed that the use of the Bimo-CF starter, the Berhasil starter and the BRIN starter during fermentation affected the decrease in moisture content, protein content, ash content, fiber content, phosphorus, and increased fat and dry matter content.

Abstract

The number of restaurants has increased recently and leads to a pierce competition in this business. To be more competitive, restaurant owners need to pay more attention on customer satisfaction. This study is aimed to examine customer satisfaction in restaurants using three variables, namely food quality, services, and environment facilities in a restaurant. Unlike studies in this area the variables were evaluated using food safety criteria where the customers’s knowledge about food safety issues were measured to analyze whether it affects the customer perception and satisfaction. The importance-performance analysis (IPA) is used to explain which attributes that need to be improved after mapping the customer expectations and perceptions. Implementing IPA to could help restaurant owners to concentrate on improving the priority quality attributes, i.e., the attributes that are important for customers but have relatively low performance. A questionnaire with food safety perspective question were distributed to 400 customers and 395 questioner were completed. The IPA Diagram reveals that the higher the consumer's knowledge the more attributes were suggested to be improved.

Abstract

Non-thermal preservation has become popular recently for the preservation of animal-based products. One of the non-thermal preservation methods is the electric field (EF) treatment of food, which can suppress enzyme and microorganism activity. The EF treatment itself consists of various types, including pulsed electric fields (PEF), high-voltage electric fields (HVEF), and alternating capacitive electric fields (ACEF and DCEF). This review discusses the EF treatment effects, especially PEF, on animal-based product preservation, including mechanisms, advantages and disadvantages, PEF application, and its preservation effect. PEF has the potential to be widely applied in food processing. The application of PEF (Pulsed Electric Field) can be applied to animal-based products and has an effect on population age and microbial production. This is because PEF can inhibit microbial activity and growth depending on process parameters, including pulse waveform, treatment time, pulse width, pulse frequency, EF strength, and food matrix type. PEF can be used for pretreatment of liquefaction processes.
