Abstract

The development of gluten-free noodles using gembili flour offers an alternative solution to reduce Indonesia's heavy reliance on wheat flour while anticipating various health issues related to gluten consumption. This research aims to identify the physicochemical characteristics of gembili flour from five local varieties and to identify the varieties with the most potential for developing gluten-free noodles. Physicochemical characterization of flour includes measuring proximate, crude fiber, and amylose levels as well as flour pasting profile. The best varieties are identified through a theoretical approach based on the physicochemical properties of flour, especially amylose content, setback (ST), and final viscosity (FV), which are used as selection indicators. Empirical proof was carried out by measuring the cooking loss (CL) of noodles to verify the theoretical approach. The physicochemical properties of flour and CL of gembili noodles are greatly influenced by differences in varieties, except for gelatinization temperature and peak time. The Fufulu, Kapok and Kapok Kayanik varieties have high values and are not significantly different in the three selection indicators. The three varieties exhibited amylose, ST, and FV levels of approximately 23%, 204.5-276.50 cP, and 724.5-1012.5 cP, respectively. GT-Biplot analysis shows that only the Kapok and Kapok Kayanik varieties are the best varieties because they have a strong and positive relative position for the three selection indicator variables and a very negative relative position in contrast to CL compared to the other three local varieties. The Kapok variety was chosen as the best variety because it is superior in terms of nutrition and availability of raw materials compared to the other four varieties. The Kapok variety has amylose content, ST, FV, and CL of 23.19±0.34 %, 276.50±3.54 cP, 1012.5±71.4 cP, and 19.78±0.66 %, respectively.

Abstract

Biodegradable film is an alternative way to reduce conventional plastic based on petroleum, which is difficult to degrade and can cause severe environmental pollution. Biodegradable films based on chitosan, sodium alginate, sodium alginate combined with canna starch and konjac glucomannan were investigated in this research. This research aims to determine the mechanical characteristics and optimum of different polymer types and the plasticizer concentration added to the biodegradable film solution. This research was done in a completely randomized design on twelve treatment combinations. The total formulation used for each type of polymer is 2% (w/v), and the concentration of sorbitol is 1% (v/v), 1,5% (v/v), and 2% (v/v). The average thickness of this research is 0,15 – 0,20 mm, the average moisture content value for each treatment ranges from 18% - 30%, the elongation value ranges from 11,75 – 59,94%, the tensile strength value ranges from 0,033 – 0,277 MPa and Water Vapor Transpiration Rate value (WVTR) range from 2,65 – 5,91 (g/m2.hour). The mechanical characteristics of food packaging materils are based on the value of elongation, WVTR, and tensile strength. Code P4S2 has the applicable value of elongation, WVTR, and tensile strength, with an elongation value of 51.75%, WVTR of 3.36 (g/m2.hour) and tensile strength of 0,05 MPa.

Abstract

Vegetable leather is a product that comes from dried vegetable puree in the form of flexible sheets. It has a chewy texture that can be consumed as a snack. Broccoli stems are vegetables that are rarely used to their full potential. The problem that often arises with vegetable leather is its poor elasticity. This research aims to determine the physicochemical properties of the broccoli stem vegetable leather. The production of vegetable leather was done by mixing broccoli stems and pectin in various concentrations (F1 (99.5% and 0.5%), F2 (99% and 1%), F3 (98.5% and 1.5%), F4 (98% and 2%).Furthermore, the mixture was dried to form a thin sheet. Then, broccoli stems and vegetable leather were analyzed for their physical and chemical properties such as texture, water content, ash content, reducing sugar, vitamin C, and crude fiber. The results showed that the addition of pectin had a significant effect on the physical properties of the texture, namely hardness 599.62N to 752.82N, gumminess 560.84N to 751.01N, chewiness 511.34N to 685.49N and do not show a significant effect for cohesiveness 0.9074 to 0.9750. Chemical properties have a significant effect on water content values 11.92% to 13.16%, reducing sugar 8.52% to 9.90%, vitamin C 40.15mg/100g to 44.58mg/100g, crude fiber 9.48% to 11.61%, and ash content 2.14% to 2.25%. The incorporation of broccoli stem with additional pectin to produce vegetable leather constitutes a food rich in fiber and vitamins. By-products of broccoli can be turned into nutritionally beneficial foods.

Abstract

Red galangal is a type of rhizome that is known to have many benefits. This study aims to get the best concentration of red galangal extract in an edible coating of meranti sago starch as an antioxidant in peeled Malang apples. The research was conducted as an experimental method, using different concentrations of red galangal extract, which are 0%, 1%, 3%, 5%, and 7% in the edible coating formulation, which was applied to peeled Malang apples and stored for eight days at 5°C. The parameter observed in the edible coating was antioxidant activity. The parameters observed in peeled Malang apples were browning index, vitamin C, weight loss, total dissolved solids, and the descriptive and hedonic sensory test of taste and flavor. Data were analyzed statistically using ANOVA and continued with DNMRT at a 5% level. Edible coating with 7% red galangal extract was the best treatment, with an IC50 of 158.41 µg/ml showing moderate antioxidant activity. On the 8th day of storing, the peeled apples had a 936.05 browning index, 3.64 mg/100g vitamin C, 45.40% weight loss, and 1.40°brix total dissolved solids. The peeled apple's sensory descriptively assessment results on taste and flavor were typical of galangal and apples. The sensory hedonistic assessment results of the peeled apples on taste and flavor were similar.

Abstract

Food processing is a way to extend the shelf life of products. In Indonesia, pumpkin and porang orange tubers are abundantly available and underutilised, but they have the potential to be developed into a local food-based product. Diversifying processed pumpkin into jam is a functional food alternative with high nutritional value. Porang flour is a thickener in foods and beverages that can stabilise the gel structure. This study aimed to determine pumpkin jam's physical, chemical, and sensory characteristics after adding porang flour. The stages of making pumpkin jam begin with making pumpkin puree, first cooking, mixing, second cooking and checking pH, then analysing physical characteristics (total soluble solids, spreadability, viscosity, and colour), chemical analysis including water content, antioxidant activity, total phenols, vitamin E, crude fibre and sensory properties. Variations of porang flour addition to pumpkin jam were (0; 0.5; 1; 1.5; and 2%). The results showed that adding porang flour influenced the physical characteristics, antioxidant activity, total phenols, vitamin C, and crude fibre of pumpkin jam but had no effect on water content and vitamin E. Adding porang flour up to 2% gave a good taste of pumpkin jam.

Abstract

Bodyscrub is a skin care product that consists of exfoliants and active ingredients. In this research, the process of making a body scrub was carried out using an exfoliant in the form of coconut dregs flour and the addition of the active ingredient, butterfly pea flower extract (Clitoria ternatea). The aim of this research is to characterize and determine the best formulation of bodyscrub products produced with the addition of 0 %, 10 %, 15 % and 20 % butterfly pea flower extract. Characterization was carried out using pH parameters, emulsion stability test, homogeneity test, spreadability test, skin irritation test, and skin moisture effectiveness test. Determining the best formulation was carried out using hedonic and Bayes methods. The results of the research showed that all bodyscrub formulations met the SNl 16–4399–1996 standards regarding sunscreen preparations, had good emulsion stability, did not cause irritation and it was seen that the addition of butterfly pea flower extract was able to make the skin more moisturized through a skin moisturizing effectiveness test. The results of the hedonic test and Bayes test showed that the formulation most preferred by the Panelists and the calculation to determine the best formulation for this coconut dregs flour bodyscrub preparation was with the addition of 20 % extract.
