Milk consumption in Indonesia decreased from 3.53 in 2020 to 2.72 kg per capita per year in 2021, prompting the food industry to enhance their products to increase milk consumption and gain a wider market. The hedonic ranking test requires panelists to rank the samples from most preferred to least preferred. Studies on food preferences have involved children to obtain accurate data for child consumers. This research aimed to determine the effect of price and product form information on the preference for chocolate milk products among children consumers. The samples consisted of four chocolate milk products in powder and ready-to-drink forms from two producers. The study recruited 120 children (46 boys and 74 girls aged 10-12 years) from schools in Jabodetabek. The hedonic ranking test method was used in three presentation types: (1) blind test (without additional information) 1 and 2, (2) price test, and (3) price test with product form information. Data analysis involved the Friedman test and LSD rank. Results indicated that the blind test 1, blind test 2, and price test showed a significant difference in preference at a significance level of 0.05. However, the price test with product form information did not demonstrate any significant differences in preferences, although some samples changed their ranking, specifically ready-to-drink milk. The milk drink with the lowest price was ranked 2.

Frozen yogurt has the tendency to undergo recrystallization during storage, resulting in a sandy texture that necessitates the use of a stabilizer. The purpose of this study was to investigate the impact of milkfish bone gelatin on the quality of frozen yogurt, as the product may recrystallize during storage, leading to undesirable sandiness that requires a stabilizer. Various concentrations of milkfish bone gelatin stabilizer (0, 0.3, 0.6, and 0.9% (w/w)) were added to frozen yogurt, and the samples were tested for total solids, overrun, melting time, LAB profile, and sensory characteristics. The results showed that the addition of gelatin from milkfish bone increased total solids and melting time, decreased overrun, maintained the cell count of LAB, and softened the texture. However, there was no significant difference (p>0.05) observed in non-fishy aroma, white color, hedonic scores, and sour taste of frozen yogurts after one week of storage. The PCA analysis indicated distinct clusters between frozen yogurt with and without the addition of milkfish bone gelatin, which was consistent with ANOVA and Kruskal Wallis results. Based on the findings, the recommended treatment is to add 0.3% milkfish bone gelatin to frozen yogurt with a total solids content of 34.53%, overrun of 17.58%, melting time of 14.75 minutes, LAB profile of 4.2×108 CFU/mL, white color score of 7.64, non-fishy odor score of 8.40, sour taste score of 6.44, soft texture score of 7.88, and overall preference score of 8.20 (on a 1-10 scale).

Work productivity can be improved by minimizing waste on the production line. This study aimed to identify the flow process, evaluate constraints and waste, and design improvements in curry sauce production. Using Value Stream Mapping based on Lean Manufacturing principles, the study analyzed the production process through three stages: (1) current state mapping; (2) identification of constraints and waste; and (3) development of a future state map. The waste identified on the production line included worker/product movement, waiting time, and overproduction, resulting in a total lead time of 25621.4 seconds. Future state improvements, such as the implementation of Standard Operational Procedures (SOP), optimization of worker numbers, maintenance of equipment, and use of efficient machines, reduced the lead time to 25018.2 seconds. The study demonstrates the potential for increased productivity and resource/energy utilization through production line improvements.

Pengaruh Blansir dan Tween 80 pada Pengeringan Busa terhadap Karakteristik Serbuk Seledri

Instant powder drinks are gaining popularity due to their practicality, durability, and ease of storage. As a result, fresh celery was converted into instant celery powder. The foam-mat drying technique was utilized to produce the celery powder because of its low drying temperature of 60°C and relatively fast drying process. To prevent food deterioration and enhance the characteristics of celery powder, the blanching process was employed. Tween 80 was also used to produce foam, which facilitated the foam mat drying process of celery. This study aimed to examine the impact of blanched or un-blanched treatment and the concentration of tween 80 on the physical and chemical characteristics of celery powder. The experiment used a completely randomized design with two factors, namely blanching treatment and the concentration of tween 80 (0.1%, 0.5%, 1.0%). Yield, water content, solubility in water, antioxidant activity, total phenol, and yield of celery powder were tested. The results indicated that increasing the concentration of tween 80 had a positive effect on the yield, solubility, antioxidant activity, and total phenols of celery powder products, but had a negative impact on the moisture content of the product. The treatment of un-blanced/blanching had a positive effect on the solubility, antioxidant activity, and total phenol of the product but a negative impact on the yield and moisture content of the product. The best celery powder product was produced by treating it with blanching and tween 80 concentration of 1%. It had the following characteristics: solubility of 93.87±0.28%, antioxidant activity of 251.22±4.67 mg AEAC/100 g, phenolic total of 77.44±2.80 mg GAE/100 g, and moisture content of 4.59±0.02%. The yield of celery powder obtained was 12.38±0.2%.
