Abstract

All modern lifestyles such as unhealthy eating patterns and lack of exercise can trigger the accumulation of free radicals in the human body, where the human body cannot neutralize these free radicals fast enough because of the large number of free radicals that have accumulated in it. Therefore, antioxidant compounds need to be consumed to suppress free radicals. In this study, mulberry is promoted as a natural, functional, and dye source that has been explored for further applications in food and beverages. This research aims to develop natural coloring products from mulberry fruit through extraction and encapsulation processes. Furthermore, hedonic testing was also carried out to determine the panelist's preference level for jelly products using mulberry fruit dyes. Mulberry fruit is extracted, encapsulated by freeze drying method, and processed into a natural dye in jelly products. Mulberry fruit extract contains vitamin C 4.1 g/ml, anthocyanin content of 215.16 mg/L, and antioxidant activity of 73.25. Mulberry encapsulates can be used as a natural dye in jelly products. Based on hedonic testing, jelly products made from natural dyes have superior taste and texture. Further development of natural mulberry fruit encapsulated dyes needs to be done to increase solubility, color sharpness, aroma and color stability

Abstract

Pluchea indica Less has been developed into tea bag because it contains a number of phytochemical compounds, such as lignin, terpenes, benzoids, phenylpropanoids, alkanes, saponins, catechins, alkaloids, tannins, sterols, phenolhydroquinones, and flavonoids, which have been shown to have several biological activities, such as antioxidants, anti-inflammatory, anticholesterol, and antihyperglycemic. In its development, pluchea tea can be combined with black tea to produce certain functional values. Consumption of pluchea-black tea in daily life can be done with the addition of lemon or honey to increase antihyperglycemic activity. However, this study focused on determining the profile of phytochemical compounds and antihyperglycemic activity of pluchea-black tea honey drink. The research design used was a Randomized Block Design (RAK) with one factor including honey concentration consisting of six treatment levels: 0, 1, 2, 3, 4 and 5% (v/v). Each treatment was repeated four times. Parameters carried out are the profile of phytochemical compounds and antihyperglycemic activity through in vitro analysis, namely the activity of inhibiting a-amylase and a-glucosidase enzymes. The results showed that the use of honey in the manufacture of pluchea-black tea had an effect on the profile of phytochemical compounds and antihyperglycemic activity. The use of honey with a concentration of 5% produced the highest antihyperglycemic activity, 73.21±3.57% for the ability to inhibit the alpha-amylase enzyme and 77.27±5.25% for the ability to inhibit the alpha-glucosidase enzyme, respectively

Abstract

Tahu walik is a snack product originating from Banyuwangi but has been developed in other areas such as Galengdowo Village, Jombang. To develop Galengdowo's tahu walik products that were able to compete inmarket, it was necessary to conduct research related to product sensory and consumer acceptance. The five sample variants used in this study were tahu walik without seasoning (T0), original seasoning (T1), balado seasoning (T2), salted pepper seasoning (T3), and commercial tahu walik (T4) for comparison. A total of 40 panelists conducted a hedonic analysis of the product's appearance in the packaging, shape, color, crispness, taste, and oily. The results showed that the highest purchase motivation was seen in T1 and T2, which were reddish, while the assessment of the packaging and sample's shape was not significantly different. The crispness value of T0 was the lowest compared to the other four samples which were not significantly different. Panelists most liked the taste of T3, T2, and T4 while T0 was the lowest, while the oily feeling was felt the most in sample T0 and the lowest in T2. Based on Simple Additive Weighting, T2 has the highest rank while T0 is the lowest. The difference in the type and color of the seasoning greatly influenced the panelists' preferences and their decision to buy tahu walik products. It can be concluded that the tahu walik processing industry in Galengdowo Village needs to develop its products to increase competitiveness in the market.

Abstract

Hypercholesterolemia is a condition in which the concentration of cholesterol in the blood exceeds the normal value. Yogurt is food product that has been shown to lower blood. The addition of inulin can support the cholesterol-lowering effect of yogurt. Gembili (Dioscorea esculenta L.) is a high inulin food ingredient. This study aims to determine the effect of giving gembili yogurt (D. esculenta L.) on the lipid profile (total cholesterol, LDL, and triglyceride) of hypercholesterolemic rats. The study was conducted on 30 male hypercholesterolemic Wistar rats which were grouped using a simple randomized system into 1 control group and 4 intervention groups. Subjects were given 1, 2, 3, and 4 ml/day of gembili yogurt for 14 days. Total cholesterol, and LDL were determined using the CHOD-PAP method and triglyceride level was determined using the GPO-PAP method. Giving gembili yogurt with doses of 1, 2, 3, and 4 ml/day within 2 weeks could significantly reduce lipid profile on hypercholesterolemic rats, the largest decrease was occurred at group with a dose of 4 ml yoghurt/day with total cholesterol levels of 100.68 mg/dl, LDL levels 28.87, and triglyceride levels 85.80 mg/dl

Abstract

The golden snail (Pomacea canaliculata) is an animal that lives in rice fields and is one of the agricultural pests that often suffers and can interfere with the growth of rice plants because of its very fast development. unused and become waste for the environment. The golden snail shell contains a chitin polysaccharide which can be reduced to chitosan (β1-4 N-acetyl D-glucosamine) through the deacetylation stage, namely the process of taking the acetamide group in chitin (CH3CONH) so that it becomes an amine group (NH2) in chitosan. The manufacture of chitosan is carried out through 3 stages, namely the process of deproteination, demineralization, and deacetylation. The purpose of this study was to determine the characteristics and quality of chitosan produced from golden snail shells. Based on the analysis conducted, chitosan has a yield of 53.91%; water content 1.68%; ash content 12.31%; molecular weight 640.83 kDa; solubility 95.53; and deacetylation degree 82.33%.

Abstract

Potatoes are a commodity that has the potential to be developed as a source of carbohydrates to support food diversification programs, increase farmer incomes, non-oil and gas export commodities, and processed industrial raw materials. One of the processed products from potatoes that are typical and popular with Indonesian people is balado potato chips. As a product that will ultimately be consumed, of course, the value of product safety (food safety) in the form of shelf life information needs to be considered. Product samples were incubated in an incubator with three different storage temperatures, namely 25°C, 30°C, and 45°C. Samples were analyzed with hedonic parameters, FFA levels, and water content every 7 days for 28 days (days 0, 7, 14, 21, and 28). The product shelf life at 25 °C, 30 °C and 45 °C respectively 37, 36 and 32 days. it is recommended that potato chip products be stored in closed packaging and stored in a cool place and avoid being stored in a place exposed to sunlight which will affect storage temperature and also free fatty acid levels which can cause rancidity.
