Abstract

Shrimp paste is a source of protein because the protein of shrimp paste has a high protein (15-20 g/100 g). However, shrimp paste is only consumed as a flavor and seasoning mixture. The study was aimed to determine the quality of organoleptic and chemical of shrimp paste using the difference of salt and cooking time. The used method was an experimental method with a factorial Completely Randomized Design (CRD) consisting of 3 treatments, namely A1 (10 g salt), A2 (15 g salt) and A3 (20 g salt). Meanwhile, cooking time was 30 minutes, 45 minutes, and 60 minutes. The tested parameters were organoleptic (flavor, odor, texture, and appearance), proximate (moisture, ash, protein, and fat), and pH. The results showed that the interaction between 15 g salt and 45 minutes of cooking time was the best treatment with the organoleptic of 7.29 flavor (shrimp taste slightly reduced, less salty), 7.59 odor (the specific odor of shrimp paste), 7.21 texture (thick, homogenous, soft), 7.63 appearance (blackish brown). The proximate of shrimp paste was 38.12% moisture, 3.05% ash, 9.68% protein, 0.72% fat, and 7.05 pH.

Abstract

The abundance of shrimp waste is a problem that has not yet been completely resolved and research is still ongoing. One effort that can overcome this problem is to use it as a raw material for making shrimp paste. The purpose of this research was to utilize shrimp shell waste as a food additive.  The research method used was experimental with five treatments, namely A1B1 (0:100), A2B2 (25:75), A3B3 (50:50), A4B4 (75:25) and A5B5 (100:0). Meanwhile, storage time was P1 (1 day), P2 (4 day), P3 (7 day) and P4 (30 day). The tested parameters were moisture content, pH and organoleptic (descriptive).  The results showed that the best formulation was the ratio of shrimp shell waste and anchovy of 25:75 (A2B2) with P3 storage time. The value of moisture content was 8.1% and pH was 7,3.  The smell of shrimp paste was not too strong with a reddish yellow color and a slightly rough texture.
