Abstract

Softbone milkfish is a fishery product that easily damaged during storage. One of the efforts to inhibit thedamage of softbone milkfish was using vacuum packaging. The purpose of this study was to determine thechanges quality of softbone milkfish which were vacuum packed during storage at room temperature. Freshmilkfish was heating with high pressure by using a pressure cooker. Softbone milkfish was then stored at roomtemperature for six days. Analysis was carried out every three days for the parameters of free fatty acids, TVBN,and organoleptics. The results showed that the number of free fatty acids and TVBN increased during storage.Free fatty acids and TVBN of softbone milkfish with vacuum packaging after sixth days of storage were 2.95%and 15.95 mgN/100g, respectively. This value was lower than the non-vacuum softbone milkfish. Based onorganoleptic analysis, softbone milkfish with vacuum packaging was still suitable for consumption until the thirdday of storage. This showed that vacuum packaging can extend the shelf life of softbone milkfish.

Abstract

Shrimp crackers are a type of dry food made from tapioca flour, shrimp and other additives. Shrimp crackers with the addition of fish bone flour nanocalcium is an alternative food that can be developed as a source of calcium. The purpose of this study was to determine the effect of adding nanocalcium tilapia bone flour to physico-chemical characteristics and the best concentration of tilapia nanocalcium bone in shrimp crackers to be accepted by panelists. This study used a Completely Randomized Design (CRD) with one factor, namely the concentration of addition of tilapia nanocalcium bone, namely 0%, 5%, 10%, and 15% which was done 3 times. Data were analyzed using ANOVA and continued by Tukey test if there were significant differences. The results showed that the addition of tilapia nanocalcium bone significantly affected the increase in the ash and calcium levels of shrimp crackers, while the water content, protein and developmental power decreased with the addition of increasing tilapia bone nanocalsium. The addition of 10% tilapia bone nanocalcium is the best concentration based on panelist acceptance with the category of very fond of the parameters of smell, taste, and texture, while for the panelist appearance parameter accepts in the like category. Shrimp crackers with the addition of 10% nanocalcium contain 10.76% water content; ash content 13.81%; protein content 2.40%; 2.12% calcium content and 42.62% swelling power.

Abstract

Shrimp paste is one of fermented product that use either shrimp (Acetes sp.), or fish, or both of them as raw materials. The use of synthetic dyes on shrimp paste is still often done. This is dangerous because it can give bad effect to the health of consumers. Therefore, it is necessary to use natural dyes instead of synthetic dyes. One of natural dyes that can be used is peel of dragon fruit (Hylocereus polyrhizus). Peel of dragon fruit has anthocyanin pigment that can give red color. The aimed of this research was knowing the effect of adding peel of dragon fruit extract (30%; 35%; 40%) to the color of shrimp paste. The treatments in this study were the addition of different concentrations of peel of dragon fruit extract at third grinding shrimp paste in triplicate. The experimental design used was Completely Randomized Design. The parameters observed include moisture content, salt content, protein content, pH, color, and sensory. Parametric data analyzed by Analysis of Variance (ANOVA) and further test by Honestly Significant Difference (HSD) test if these any differences between samples. Non-parametric data analyzed by Kruskal-Wallis and further test by Mann Whitney. The research’s result showed that processing shrimp paste with different peel of dragon fruit extract concentrations gave significant effect (P<5%) on moisture content, salt content, pH, and color. Moisture content values was ranged from 35,0741,01% and salt content values was ranged from 6,35-7,05%. pH values was ranged from 6,40-7,20. Shrimp paste with peel of dragon fruit extract 40% had more red color and improve the appearance of shrimp paste.
