Abstract

Red curly chili (Capsicum annuum L.) is a commodity that has a high use value for the life of the Indonesian people, but is very susceptible to damage due to fracture while handled in the supply chain system. This is thought to be the main factor that causes a decrease in the shelf life of curly red chili. This study aims to determine the effect of the percentage of fractured chilies on the physical quality and respiration rate of curly red chilies, and also to determine the minimum percentage of fractured chilies that can affect the physical quality and respiration rate of curly red chilies during storage period. The experimental design used in this study was a completely randomized factorial design (CRD-factorial), with the first factor being the percentage of fractured chilies consisting of 0%, 4%, 8%, and 12%, and the second factor being the length of storage time consisting of 0, 2, 4, and 6 days. All treatments were repeated 2 times so that 32 experimental units were obtained. Data were analyzed by analysis of variance (ANOVA) and if the treatment had an effect on the parameters, it was continued with Duncan's Multiple Range Test (DMRT). Parameters observed were weight loss, moisture content, color, texture and respiration rate. The results showed that the interaction between the percentage treatment of fractured chili and storage time had a significant effect on weight loss and respiration rate, and had no significant effect on water content, color, and texture of curly red chili. The minimum percentage of fractured chilies that could have a significant effect on the physical quality and respiration rate of curly red chilies during the storage period was 4%, with a quality that is close to the control treatment until the 4th day of storage which are: 22.36% weight loss; 72.26% water content; 33.1 L* value; 48.3 a* value; 34.1 b* value; 34.08 N texture, and 17.46 mgCO2/kg.hour respiration rate. Keywords: curly red chili, physical quality, respiration rate

Abstract

Brownies crispy are chocolate cakes that have a crunchy texture so they are quite popular as a snack, but based on the formulation brownies crispy have a fairly low fiber content. The addition of cocoa bean husk powder to crispy brownies can increase the fiber content of the product. This study aims to determine the effect of adding the right cocoa bean husk powder (Theobroma cacao L.) to produce brownies crispy with the best physicochemical and organoleptic properties. The design used in this study was a Completely Randomized Design consisting 6 concentration levels of cocoa bean husk powder, namely: 0%, 5%, 10%, 15%, 20%, and 25% with three replications. Parameters tested were water content, crude fiber content, antioxidant activity, texture (hardness), color intensity (L, a*, and b*), and hedonic sensory evaluation (color, aroma, texture, taste, and overall acceptability). The data were analyzed using variance and if the treatment had a significant effect then it was continued with the Duncan Multiple Range Test (DMRT) at 5% level using Statistical Product and Service Solution (SPSS). The results showed that the concentration of cocoa bean husk powder had a significant effect on water content, crude fiber content, antioxidant activity, hardness texture profile, color intensity (L, a*, and b*) and had no significant effect on hedonic sensory analysis on parameters of color, aroma, texture, taste, and overall acceptability. The best characteristics of brownies crispy was the addition of 25% cocoa bean husk powder with a moisture content value of 1.38%, 4.15% crude fiber content, 48.38% antioxidant activity, 32 hardness texture profile 32,24 N, color intensity L 23.03, a* 9.20, b* 14.20, and sensory acceptability was liked.

Abstract

Donuts are a snack food made from wheat. The availability of wheat in Indonesia is entirely supplied from abroad, so it is necessary to reduce the use of wheat by finding alternatives to the use of other flours that can replace wheat flour, one of them is tofu dregs flour because it has high nutritional and fiber content.This study was aimed to determine the effect of comparison of wheat and tofu dregs flour on the characteristics of donuts and to determine the right ratio of wheat and tofu dregs flour to produce donuts with the best characteristics. This study used a completely randomized design with treatment ratio of wheat and tofu dregs that consist of 5 levels, namely 100:0, 95:5, 90:10, 85:15, 80:20 percent. The data were analyzed using variance analysis and if the treatment had a significant effect then it was continued with Duncan's test. The results showed that the ratio of wheat and tofu dregs flour had a significant effect (P<0.05) on moisture, protein content, fat content, carbohydrate content, crude fiber content, volume of development, hardness, and sensory properties of the product, but had no significant effect ( P>0.05) on the ash content of the product. The treatment ratio of 95 percent wheat and 5 percent tofu dregs flour produced donuts with the best characteristics, namely with moisture content 26.34 percent, ash content 1.95 percent, protein content 8.96 percent, fat content 27.65 percent, carbohydrate content 35.10 percent, crude fiber content 1.65 percent, volume of development 210.29 percent, hardness 2.43 N, with color, aroma, taste, texture and overall acceptance preferred by the panelists.

Abstract

Abstract If chocolate jam was processed using cocoa butter, it resulted low spreadability. Therefore, it was necessary to investigate the use of liquid oils such as soybean oil as an alternative. The aim of this research was to determine the effect of ratio of cocoa powder to soybean oil and identify the optimal ratio for the best characteristics of chocolate jam. This study used Completely Randomized Design (CRD) with six treatment of cocoa powder and soybean oil ratios, 64%:36%, 61%:39%, 58%:42%, 55%:45%, 52%:48%, and 48%:52%. Each treatment was repeated three times, resulting 18 experimental. Data were analyzed using Analysis of Variance (ANOVA), and if a significant effect was observed (P<0,05), Duncan’s Multiple Range Test (DMRT) was conducted. Sensory evaluation were analyzed using Principal Component Analysis (PCA). The research results showed that the ratio of cocoa powder to soybean oil had a significant effect on the characteristics of the chocolate spread. Soybean oil improved the texture quality and spreadability of the chocolate spread without damaging the flavor and sensory acceptance. Chocolate jam with best characteristics was obtained from the formulation containing 55% cocoa powder and 45% soybean oil which corresponds to treatment P4, with characteristics of moisture content 16.79%, ash content 1.58%, fat content 25.26%, hardness 1,36 N, cohesiveness 0,31, adhesiveness 6,36 Nmm and the treatment received "liked" ratings on all hedonic attributes and was rated as "weak" in the spreadability intensity test. Keywords: chocolate jam, cocoa powder, soybean oil Abstrak Selai cokelat jika dibuat dengan lemak kakao akan menghasilkan selai dengan daya oles yang kurang baik, oleh karena itu perlu diteliti menggunakan minyak cair seperti minyak kedelai. Tujuan penelitian ini untuk mengetahui pengaruh perbandingan bubuk kakao dan minyak kedelai serta untuk mendapatkan perbandingan tepat untuk memperoleh karakteristik selai cokelat terbaik. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan enam taraf perlakuan perbandingan bubuk kakao dan minyak kedelai, yaitu 64%:36%, 61%: 39%, 58%: 42%, 55%: 45%, 52%: 48%, dan 48%: 52%. Setiap perlakuan dilakukan pengulangan sebanyak tiga kali, sehingga terdapat 18 unit percobaan. Data dianalisis menggunakan Analysis of Variance (ANOVA) dan apabila didapatkan perlakuan yang berpengaruh secara signifikan (P<0,05) akan dilanjutkan dengan uji Duncan’s Multiple Range Test (DMRT). Hasil pengujian sensoris dianalisis menggunakan Principal Component Analysis (PCA). Hasil penelitian menunjukkan bahwa perbandingan bubuk kakao dan minyak kedelai berpengaruh nyata terhadap karakteristik selai cokelat. Minyak kedelai meningkatkan kualitas tekstur dan daya oles selai cokelat, tanpa merusak rasa dan penerimaan sensoris. Selai cokelat yang memiliki karakteristik terbaik dihasilkan pada perbandingan 55% bubuk kakao dan 45% minyak kedelai dengan kadar air 16,79%, kadar abu 1,58%, kadar lemak 25,26%, hardness 1,36 N, cohesiveness 0,31, adhesiveness 6,36 Nmm, dengan kriteria suka pada seluruh atribut uji hedonik serta kriteria lemah pada uji intensitas daya oles. Kata Kunci: bubuk kakao, minyak kedelai, selai cokelat
