Abstract

Marshmallow is a type of soft candy that is popular with consumers, including confectionary products made from gelatin, sugar and sweeteners. Innovations in making marshmallows were carried out with the addition of propolis to increase the functional value of food so that it has a positive impact on health. The purpose of this research is to determine the effect of propolis addition on the texture, water content, water activity (Aw), and color (L, a*, b*). The materials used in this research included propolis, gelatin, sugar, water, and cornstarch. The research method applied was experimental research using a Completely Randomized Design (CRD) with four treatments and five replications consisting P0 (0% propolis), P1 (3% propolis), P2 (5% propolis), and P3 (7% propolis). The observed variables were texture, water content, Aw, and color (L, a*, b*). The obtained data were analyzed using Analysis of Variance (ANOVA), and if significant differences were found, further analysis was conducted using Duncan’s Multiple Range Test (DMRT). The results of the research on marshmallows with the addition of propolis showed mean values for texture (0.56 N-0.92 N), moisture content (26.21%-34.26%), Aw (0.804-0.811), lightness (L) (92.90-93.58), redness (a*) (0.060-0.212), and yellowness (b*) (24.826-25.542). The conclusion of this research is the addition of propolis to marshmallows significantly affected texture and water content but had no effect on Aw and color (L, a*, b*) values. The best treatment was P1, with 3% propolis addition, resulting in a texture of 0.920 N ± 0.268, water content of 31.408% ± 0.571, Aw of 0.804 ± 0.003, L value of 93.132 ± 0.769, a* value of 0.196 ± 0.092, and b* value of 25.542 ± 0.559. These results indicate that the addition of 3% propolis can improve texture and maintain balanced moisture content without altering the stability of water activity and color. Based on the results of this study, it is recommended to use 3% propolis in marshmallow production, as it yields the best quality in terms of texture, moisture content, Aw, and color (L, a*, b*).

Abstract

This study aimed to evaluate the effect of rice bran oil (RBO) supplementation on the physicochemical properties, microstructure, and oxidative stability of chicken-based meat emulsion products. RBO is rich in natural antioxidants such as γ-oryzanol and tocopherols, which may enhance product quality. A Completely Randomized Design (CRD) was used with four treatments (0%, 6%, 8%, and 10% RBO) and six replications. Parameters measured included pH, peroxide value (PV), color values (L*, a*, b*), microstructure (SEM), moisture, ash, fat, protein, carbohydrate, water activity (Aw), free fatty acids (FFA), and total acidity. The addition of RBO significantly (P<0.01) reduced PV, FFA, and total acidity, indicating improved oxidative stability. It also enhanced protein content, microstructural integrity, and textural properties. Although total fat content increased, the proportion of unsaturated fatty acids improved the lipid profile. Reduction in water activity suggested enhanced shelf stability. These findings demonstrate that Adding 10% rice bran oil (RBO) to chicken meat emulsions improved emulsion stability, reduced lipid oxidation and free fatty acids, enhanced protein retention, and improved microstructure.

Abstract

The integrated cattle and oil palm production is currently recognized as one of the potential strategies to fulfill national meat demand in Indonesia. This study investigated the effect of parity on the performances of Brahman cross cows and their calves kept under integrated cattle and oil palm production. The cows receive natural mating with the provision of Brahman cross bulls (bull:cow ratios of 1:20). Data of body weight and body condition score of 300 cows were recorded after parturition. Data of body weight and weaning weight of their 600 calves (300 calves of each of parity 1 and 2) were also included in this study. Data were compared between parity 1 and 2 by using paired Wilcoxon signed-rank test. The results demonstrated that the cows in parity 2 had higher (P0.001) body weight and body condition score than those in parity 1. Parity 2 also increased (P0.001) birth and weaning weight of calves as compared to parity 1. It could be concluded that parity has a significant contribution to the performance of Brahman cross cows and their calves, with parity 2 provides better performance than parity 1.

Abstract

In Indonesia, apples are one of the types of fruit that are widely cultivated and widely consumed as processed foods, such as apple cider vinegar. One of the producers of apple cider vinegar is CV Sinar Tirta Indonesia, which is located in Malang. Apple cider vinegar produces a by-product in the form of apple pulp. Innovation is needed so that apple pulp by-products are not only used for animal feed mixtures that have low selling value. Apple pulp by-products, which consists of pulp and skin that has extraordinary nutrition, makes it very suitable to be processed into useful food. To achieve environmentally friendly product processing, it must be able to change by-products into products with economic value as much as possible, as shown in this community service activity, by changing apple cider vinegar by-products into flour and ingredients for making cookies.

Abstract

Rambak crackers are made from cattle hides through the process of cleaning, threshing the hair and boiling. The research objective was to determine the physicochemical qualities of fresh cowhide, boiled cowhide, dried rambak crackers (krecek) and fried rambak crackers from 3 drying methods, namely, sun (M), oven (O), and sun oven (MO) drying methods. The material used was local cowhides from the slaughterhouse in Malang city. This experimental and counting method used a randomized block design with 3 treatments and 6 replications. The descriptive results showed that the average protein content in fresh cowhide, cecek and krecek was 36.18-84.97%, and the average ash content was 0.14-0.32%. The experimental results revealed k values of 170.40-217.54%, moisture contents of 16.55-18.22%, Aw values of 0.68-0.73, L values of 37.56-38.83, a* values of 0.58-1.26, and b* values of 6-6.98. The average fat content of the fried rambak crackers after sun, oven and sun oven drying was 5.83-29.06%, the average moisture content was 3.77-5.05%, the average aroma was 3.9-4.6, the average shape was 3.1-3.5, and the average preference was 2.5-3.3. In conclusion, 3 drying methods based on physicochemical and organoleptic properties can be applied and are preferred by panelists because drying using the oven method also has potential for cowhide crackers.

Abstract

The purpose of this current study was to evaluate the influence of nutritional flushing on body morphometrics of female breeding goats. This study used 32 local female goats or does with an average age of 3.281.08 years and an average body weight of 42.478.28 kg. The goats were distributed in a completely randomized design using a 2 x 2 factorial pattern with 8 replications. The first factor was the flushing feed (FF) type, consisting of rice bran and concentrate, whereas the second factor was the level of tannin-protected arginine (TPA: 0 and 300 mg/kg). The body morphometrics observed in this study were initial body length (IBL), final body length (FBL), body length change (BLC), initial chest girth (ICG), final chest girth (FCG), chest girth change (CGC), initial wither height (IWH), final wither height (FWH), and wither height change (WHC). The IBL, FBL, BLC, ICG, FCG, IWH, FWH, and WHC of the local does were not significantly different (P0.05) after receiving the FF type. However, FF significantly affected the CGC of the goats (P0.001). The use of concentrate for the local female local goats resulted in a higher CGC (P0.001) compared to the use of rice bran. On the other hand, TPA did not significantly affect all body morphometrics of the goats (P0.05). Thus, it can be concluded that the use of concentrate leads to higher chest girth change, giving better body growth compared to the use of rice bran. The addition of tannin-protected arginine was also found to have no significant contribution to the body morphometrics of the local female goats. _____________

Abstract

Chicken liver is rich in protein and iron, which can help prevent anemia and stunting. One innovation is processing chicken liver into nuggets, a popular ready-to-eat food product. This study aims to explore the effects of various flours (cornstarch, soybean, pumpkin, and carrot) on the characteristics of chicken liver nuggets, including yield, texture, water activity, moisture content, and color. By utilizing nutrient-dense flours, it is hoped that chicken liver nuggets can become more nutritious, healthier, and meet quality standards, while also holding the potential for commercialization on both household and large-scale industries, supporting community food security. This research employed a Completely Randomized Design (CRD) with four treatments and three replications. The tested variables included yield, water activity (Aw), water content, texture, and color. The analysis results indicated that the treatments had a highly significant effect (P>0.1) on yield and color, a significant effect on moisture content, and no significant effect on texture and water activity. The findings revealed that chicken liver nuggets had average yield values of 96.38%-103.27%, texture of 4.094 N-5.236 N, Aw of 0.857-0.870, moisture content of 33.70%-42.04%, and color values of L* (lightness) 36.90-43.27, a* (redness) 12.67-16.77, and b* (yellowness) 19.17-22.23. This study demonstrates that the use of cornstarch, soybean, pumpkin, and carrot flours can improve the quality of chicken liver nuggets, making them suitable for consumption as a menu variation with quality that complies with the Indonesian National Standard (SNI) for chicken nuggets with additives.

Abstract

Jelly candy is a type of soft candy made from fruit extract, sugar, and gelatin. The high sugar content may have adverse health effects. Therefore, honey powder has potential as a partial sugar substitute as well as a functional ingredient. The aim of this study was to determine the best percentage of honey powder substitution to replace part of the sugar in milk jelly candy. The main raw material was cow’s milk with honey powder as a sugar (sucrose) substitute. The study used a Completely Randomized Design (CRD) with four treatments and four replications. The treatments were T0 (25% sugar without honey powder), T1 (19% sugar + 6% honey powder), T2 (12.5% sugar + 12.5% honey powder), and T3 (6% sugar + 19% honey powder). The results showed that partial substitution of sugar with honey powder had a highly significant effect (p < 0.01) on reducing sugar (5.56-11.43%), antioxidant (90.16-116.73 ?g/mL), and color of sensory evaluation (3.58-4.05), as well as a significant effect (p < 0.05) on protein content (11.51-12.50%), taste (3.78-4.18), aroma (3.53-3.80), and overall acceptance (3.50-3.90), but no significant effect (p > 0.05) on texture (3.43-4.18). It can be concluded that substituting part of the sugar with honey powder in milk jelly candy affects the chemical properties. However, based on the evaluation, the control treatment with 25% sugar and no honey powder still be the most preferred product by panelists.
