The addition of nutmeg (Myristica fragrans) essential oil to intensify the aroma as a replacement of rum considering halal supply chain for cookies that use durian (Durio zibethinus) seeds waste-based flour to create sustainable advantages

The sources of aroma can be varied according to the food’s type and it is part of the ingredients that has an important role to increase people interest in certain foods. However, the most popular source of aroma is rum which is not halal for Muslim community. In this research, the researcher wanted to see the effect of adding essential oil from nutmeg seeds to the addition of the aroma of cookies made from durian seed flour to see the acceptance of customers of the product innovation using nutmeg essential oil to increase the aroma of cookies or food products that usually using rum or non-halal products and seeing the long-term impact that could possibly create sustainability advantages by occupying the waste of durian seed in to flour to substitute wheat flour. This study uses an organoleptic test. The science that uses the human senses to measure the texture, appearance, aroma, and taste of a food product is called sensory or organoleptic evaluation. Assessment of appearance, taste, and texture describes consumer acceptance of a product. The results show that consumers acceptance for this product innovation well so that the control prescription that can be given for this product innovation can be continued. The second experiment got the highest response compared to the first and third experiments.

Effect of Different Black Quinoa Fractions (Seed, Flour and Wet-Milling Coproducts) upon Quality of Meat Patties during Freezing Storage

In this study, the quality of meat patty samples containing different black quinoa fractions (seed, flour and wet-milling coproducts) was evaluated during freezing preservation. Composition, physicochemical parameters (aw, pH, colour and texture), cooking properties, lipid oxidation and sensory characteristic were studied in four batches (control and 8% concentration of quinoa seed, flour and wet-milling coproducts added) at 30, 60 and 90 days of freezing (−20 ± 1 °C). Different black quinoa fraction addition affected (p < 0.05) physiochemical properties, improved cooking properties and reduced lipid oxidations during freezing storage. Batches with flour and wet-milling coproducts added were the most stable for texture parameters and lipid oxidation during freezing. The results obtained showed that quinoa wet-milling co-products could be considered a valuable sustainable and organic food ingredient, maintaining nutritional and global qualities of the fresh meat product. In addition, freezing storage is an effective way to prolong the shelf life of patties with different black quinoa fractions, added without affecting quality.

Pengaruh Subtitusi Tepung Terigu Dengan Tepung Biji Alpukat (Persea Americana Mill) Terhadap Tingkat Kesukaan Cookies

Cookies are one of the food products that are popular with the public. The raw material for making cookies is wheat flour, which is still imported from abroad and year by year the number of imports from abroad continues to increase. Utilization of avocado seed flour will reduce the use of wheat flour and can also reduce waste from avocados. The main factor in fulfilling the quality of a product can be assessed based on the appearance of the product, the taste of the product, and the nutritional value of a product. This study aims to analysed the level of preference (taste, aroma, texture, and colour) of cookies through organoleptic tests. The design of this study used an experimental study using the RAL (Completely Randomized Design) method with two replications. Avocado seed flour substitution formulation in 4 treatments, namely control (P1), 30% (P2), 50% (P3) and 70% (P4). The research location is at the State University of Medan. The subjects (untrained panellists) of this study were 25 people. The data from the organoleptic test were analysed descriptively using the percentage of respondents' acceptance from each treatment level and to determine the effect of avocado seed flour substitution on the treatment, Kruskal Wallis statistical analysis was used. The results of this study indicate that the best formula for cookies with 50 percent substitution of avocado seed flour obtained an average value of 1.2 for taste, 0.3 for colour, 0.6 for texture, and for aroma 0.3 with a total value of 2, 4. Based on the results of the Kruskal Wallis test, it is known that there is a significant difference in perception seen from the level of preference for colour, aroma, taste, and texture of avocado seed flour cookies (p = 0.000).

STUDY OF THE INFLUENCE OF NATIVE AND GERMINATED PUMPKIN AND WATERMELON SEEDS ON THE QUALITY OF DOUGH AND BREAD

The paper examines the effect of native and germinated pumpkin and watermelon seeds on the quality of semi-finished and finished bread products. Native and germinated seeds, pre-dried and ground into flour, were used as an additive to bread in the amount 5%, 10%, 15% by weight of the flour. Pumpkin and watermelon seeds were added in order to enrich the bread with micronutrients. The influence of these additives on the quantity and quality of gluten has been analysed. It has been found that the addition of pumpkin seed flour in quantities of 5%, 10% and 15% by weight of wheat flour leads to a decrease in the gluten content and an increase in its elasticity. The study has shown that adding native pumpkin seeds does not have a significant effect on the moisture and acidity of semi-finished and finished products, and adding germinated seeds leads to a slight increase in these parameters. Thus, the moisture content of the crumb with native pumpkin and watermelon seeds added increased by 0.2–1.3%, as compared with the reference sample, and with germinated seed flour added, it increased by 0.5–2.2%. The acidity of the crumb changes slightly, within experimental error. According to the physicochemical quality parameters, the most practical amount of the additives is 5% by weight of wheat flour. A comparative analysis has been carried out to establish how addition of 5% of native and germinated pumpkin and watermelon seeds changes the organoleptic properties of bread. The analysis has shown that ready-made bread products containing native pumpkin seeds taste better and have better olfactory properties than products with germinated seeds. The nutritional and calorific values of the reference sample and of bread with 5% of pumpkin and watermelon seed flour have been compared and characterised. It has been found that the addition of native pumpkin seeds will increase the content of minerals: of iron by 230%, of magnesium by 116%, and of potassium by 118%. The addition of native watermelon seeds will increase the phosphorus content by 13%. As a result of this research, the prospects of using flour of native pumpkin and watermelon seeds to fortify wheat bread have been shown

Physicochemical characteristics of muffin from composite flour (mocaf, breadfruit, jackfruit seeds, and durian seeds)

This study aims to determine the formulation of composite flour from mocaf, breadfruit flour, jackfruit seed flour, and durian seed flour in making good quality muffin. Making muffins with composite flour formulations (mocaf, breadfruit flour, jackfruit seed flour, and durian seed flour) (P): 50%:40%:5%:5%, 50%:30%:10%:10%, 50 %:20%:15%:15%, 50%:10%:20%:20%, 100% jackfruit seed flour, 100% durian seed flour 100% breadfruit flour, 100% mocaf, and 100% wheat flour. The resulting muffins were analyzed for specific volume, ash content, protein content, fat content, carbohydrate content, and crude fiber content. The final result of the study showed that the composite flour formulation (mocaf, breadfruit flour, jackfruit seed flour, and durian seed flour) (50%:30%:10%:10%) produced the good quality muffin by deGarmo method.
