Abstract

Hard candy is one of the processed products loved by all groups from children to older people. However, hard candy containing sucrose constituent ingredients can trigger the onset of various diseases, including dental caries. The formulation of free sucrose hard candy with herbal pepper is expected to solve this problem. This study aimed to determine the characteristics of sucrose-free hard candy products from herbal pepper oleoresins. This research began with oleoresin extraction of herbal pepper using the UAE (Ultrasound-Assisted Extraction) method as a source of antioxidants and antibacterials. Oleoresin chili herbal medicine is further used to manufacture free sucrose hard candy formula. The research design used in this study used non-factorial RAL with formula variation treatment to manufacture free sucrose hard candy. The main parameters observed in this study were antioxidant activity and inhibitory power against mutant Streptococcus bacteria. The results showed that the higher oleoresin of herbal pepper can increase the content of antioxidants and antibacterial-free Sucrose Hard Candy. Using xylitol and herbal pepper extract can increase the inhibitory power of mutant Streptococcus bacteria in free sucrose hard candy.

Abstract

A drying technique utilizing solar energy on shredded apples as raw material for apple infusion has a reduced emission risk while also producing high-quality drying products.This study aimed to determine the optimum semi-theoretical mathematical model for drying shredded apples after blanching and non-blanching treatments utilizing three simple mathematical models: Newton, Henderson, Pabis, and Page. The results showed that blanched shredded apples dried using the Convective Solar Drying (CSD) method had the highest rate of decrease in the moisture ratio compared to those dried in the open sun drying (OSD). The three semi-theoretical models examined can be used to forecast the rate of decline in the water content ratio of dry shaved apples in all treatment combinations, as demonstrated by a value of R2 more than 0.9. Based on a comparison of the validity of each semi-theoretical model utilized, Page's model is the best model for characterizing the drying kinetics of shredded apples for both blanching CSD, non-blanching CSD, blanching OSD, and non-blanching OSD drying. The information acquired will be important in selecting an appropriate apple pretreatment handle and drying model for shredded apples.

Abstract

Nori is a sheet-shaped snack generally made from Porpyra red seaweed, which is not found in Indonesia. Meanwhile; the binahong plants (Anredera codifolia) are spread through out Indonesia. Binahong leaves are consumed without further processing. Binahong leaves are potential functional food, as they are rich in nutrient. They are high in vitamin A, and vitamin C. They also contain some protein, and fat.  However, binahong leaves have bitter taste and unfavored flavor. In this study, binahong leaves were processed into nori with various concentrations of carrageenan. The concentrations of added carrageenan were 1, 2, and 3 %.  The psychochemical properties of the resulting products were tested by proximate analysis and sensory tests. The result showed that the addition of carrageenan had no significant effect on water, protein, fat, and carbohydrate contents. However, it had significant difference on ash content.  Sensory testing showed that there was no significant difference between treatments in terms of appearance, taste, aroma, texture, and overall assessment.

Abstract

Amla fruit is not consumed directly because it has a sour and astringent taste, so it is widely used in various forms of dried and processed products for ease of use. Therefore, post-harvest handling of amla fruit as well as drying process is necessary. This study investigates the effect of drying method and sample thickness on the drying kinetics of amla fruit. In this study, amla was dried by sun drying and oven drying (at 40, 60 and 60°C) and sample sizes (1×0,5×0,5) cm and (1×1×0,5) cm. The results showed that the drying method and thickness of the sample affected the drying time. The shortest drying time was obtained from oven-dried samples at a drying air temperature of 60℃ and samples with smaller sizes (slice I). The semi-theoretical and empirical models were evaluated in amla fruit's drying kinetics. The fit of the model with the experimental data is determined using the coefficient determination (R2). Model Midili et al. give the best match with the highest R2 value. The effective moisture diffusivity at various drying conditions ranged from 5.747 × 10-10 to 1.242 × 10-9 m2/s for slice I and 4.522 × 10-10 to 9.213 × 10-10 m2/s for slice II. The effective moisture diffusivity is correlated with temperature using the Arrhenius equation. The activation energy needed to remove moisture from the amla fruit matrix was 20.230 kJ/mol for slice I and 22.006 kJ/mol for slice II. This kinetic study is useful for predicting the drying process yield and designing the dryer.

Abstract

A cocoa bean shell is a waste from cocoa bean processing that contains active compounds such as flavonoids, polyphenols, saponins, and tannins, where these compounds are antioxidant compounds that can be utilized as natural antioxidants in soap. This study aimed to determine the formulation by adding cocoa bean shell extract that produces solid soap with the highest antioxidant activity according to SNI 3532:2021. The Complete Randomized Design (CRD) method was used in this study with concentration treatments, which were F0 = 0% (w/v), F1 = 1% (w/v), F2 = 2% (w/v), F3 = 3% (w/v), F4 = 4% (w/v), F5 = 5% (w/v), and F6 = 6% (w/v), on moisture content, acidity (pH), organoleptic, irritation, and antioxidant activity of solid soap. The results showed that cocoa bean shell extract had an IC50 value of 68.12 ppm. The moisture content value of solid soap was in the range of 14.21-23.11%, pH 8.88-9.05, antioxidant activity of 43.33-61.46%, and non-irritating. Thus, the solid soap formulation with the highest antioxidant activity and according to SNI 3532:2021 was solid soap with the addition of 5% extract (F5).

Abstract

Nori is an authentic Japanese food made from Porphyra seaweed. However, Porphyra is difficult to cultivate in Indonesia because it generally grows in subtropical areas. The demand for nori continues to increase with the development of Japanese, Korean, and Chinese fast-food restaurants in Indonesia. Therefore, it is necessary to make nori using seaweed easily cultivated in Indonesia, namely Eucheuma cottonii and Ulva lactuca. This research aimed to study the sensory and chemical characteristics of nori from Indonesian seaweed added with breadfruit leaf extract and grass jelly. Dried Eucheuma cottonii was obtained from LIPI Oceanography, while dried Ulva lactuca was obtained from waters in Sidoarjo. Dried breadfruit leaf used in this study were obtained from processing fresh breadfruit leaf from the yards of residents of the Babakan Penghulu Village, Cinambo District. Green grass jelly leaf were obtained from Andir. Three nori formulas were made, namely the addition of breadfruit leaf extract (200 ml), a combination of breadfruit leaf and grass jelly (100:100 ml), and the addition of grass jelly (200 ml). The sensory test is carried out using the hedonic test method with 30 untrained panelists. Panellists were asked for their responses regarding color, taste, texture, aroma, and total acceptance on a scale of 1-5, from very dislike to very like. Chemical testing includes water, ash, protein, fat, crude fiber, and antioxidant activity. The results show that the best formula is the one with the addition of breadfruit leaf extract, which gave an overall acceptance score of 3.37, water content of 5.26%, ash content of 2.41 %, fat content of 2.06%, protein content of 22.24%, starch content of 59.97%, and crude fiber of 6.65%, and antioxidant activity of 702.75 ppm. Nori using local Indonesian seaweed with the addition of breadfruit leaf extract can be an alternative to commercial nori.

Abstract

An important characteristic that influences consumers in choosing sauces is texture. Therefore, fermented cassava flour adds to the chili sauce formula. The selection based on the viscosity of cassava flour increased during the fermentation process. Cassava is also a popular local food-producing starch, easily available at low prices. The study intended to describe chili sauce's physical and chemical properties and obtain the best formula for chili sauce. The experiment turned into a completely randomized design with three replications. The first stage carried out the characterization of fermented cassava flour. In the second stage, chili sauce was formulated, with the factor being the addition of fermented cassava flour concentration (0, 1, 2, 3, and 4%). The chili sauce produced is then characterized by its physical and chemical qualities. The results confirmed that the greatest chili sauce was acquired by adding fermented cassava flour by 4%. The sauce produced a water content of 76,77%, ash of 5,07%, the crude fiber of 0,48%, pH value of 4,59%, total dissolved solids of 21,20 Brix, and brightness value (L*) 33,30, 28,47 redness value (a+), 27,97 yellowish value (b+) and 19,233 cP viscosity. Fermented cassava flour is considerably potential to be used for thickener in chili sauce formulas. This study actualizes diversification of chili and cassava processed-product.

Abstract

Ruang Normal Coffee UMKM implements online buying and selling in marketing their products, but these UMKM do not yet have distribution packaging to protect the product during delivery. Based on the field survey, the distribution problems were the coffee cup packaging being dented, leaking, difficult to carry, and unattractive. The distribution packaging is currently considered not following consumer preferences because it is only in the form of clear plastic. This study aims to design packaging for distributing MSME coffee drinks in the Normal Room according to consumer preferences. The method used is Kansei Engineering (KE). KE implementation is supported by decision-making methods in determining packaging design concepts and packaging design elements. The term frequency-inverse document frequency (TFIDF) and principal component analysis (PCA) methods determine the design concept. In contrast, the Rough Set method determines the design elements. Sampling of respondents using purposive sampling with a minimum number of 30 respondents. The results of this study were that there were 21-word pairs based on TFIDF extraction and 40 packaging samples. The design concept was obtained through PCA analysis of the two main components that have a variance value of 1, namely PC-1 produces the concept of "challenging-modern" and PC-2 produces the concept of "old-fashioned-practical." The combination of design elements from rough set analysis for the “challenging-modern” concept is cardboard/corrugated material, blunt end handles, folding cartons, tray/box type without additional features, sans-serif fonts, and illustrations. Meanwhile, the "old fashioned-practical" concept consists of kraft materials, round handles, sleeve shapes, inner stands or trays/boxes, pop-up designs, classic concepts, monochrome, and illustrations. The final step is implementing the design elements into the 3D packaging mockup model. This research has an impact on the development of science and technology in the packaging design process by considering consumer feelings using quantitative methods that are more objective
