Abstract

ABSTRACTNutmeg syrup is one way to diversify products of nutmeg. IKM “Sari Fruit” is one of nutmeg syrup producers in North Sulawesi, especially in the District Sitaro. However, nutmeg syrup in the market has not specified expiration date. One method that can be used to determining the shelf life of food product is ASLT (Accelerated Shelf Life Testing). This research aims to determine the shelf life of nutmeg syrup production IKM "Sari Fruit" Sitaro using ASLT (Accelerated Shelf Life Testing) with the Arrhenius approach. The benefit of this research is to give information and advice to the industry of nutmeg syrup to determine the shelf life of the product before it is marketed. In this research, nutmeg syrup stored at 30 ° C, 35 ° C and 40 ° C for 4 weeks. The parameters used to analyze the decline in the quality of nutmeg syrup are pH, sugar content, viscosity, total yeast and organoleptic tests. The results showed that the shelf life calculations are based on the pH because it has the smallest activation energy, ie 4,025.66 cal / mol. Shelf life of nutmeg syrup at room temperature storage (27 ° C) was 13.6 weeks.Keywords : Nutmeg syrup, shelf life, ASLT, Arrhenius

Abstract

ABSTRAK  Tujuan penelitian ini yaitu menganalisis aktivitas antioksidan beras analog sagu baruk dan ubi jalar ungu. Uji warna menggunakan chromameter, senyawa antioksidan yang diuji yaitu total fenolik dan antosianin, sedangkan aktivitas antioksidan yaitu total antioksidan yang diuji secara spektrofotometri. Hasil penelitian menunjukkan bahwa warna beras analog memiliki nilai L= 62,01, a*= 12,49 dan b*= 1,54. Beras analog mengandung total fenolik sebesar 73,98 mg/L dan antosianin sebesar 7,01 mg/L dan memiliki total antioksidan sebesar 62,01 mg/mL. Sagu baruk dan ubi jalar ungu dapat dibuat beras analog yang memiliki potensi antioksidan. Kata kunci: Antosianin, total antioksidan, beras analog, sagu baruk, ubi jalar ungu  ABSTRACT  The aim of this research was to analyze antioxidant activity of rice analog from baruk sago and purple sweet potatoes. Color was evaluated using chromameter, antioxidant compound which evaluated was total phenolic and anthocyanin, and antioxidant activity was total antioxidant which evaluated using spectrophotometry. The result showed that rice analogue possess L= 62,01, a*= 12,49 dan b*= 1,54. Rice analogue possess total phenolic 73,98 mg/L and anthocyanin 7,01 mg/L, and exhibit total antioxidant 62,01 mg/mL. Baruk sago and purple sweet potatoes can be used to produce rice analog which possess antioxidant potency. Keywords: Anthocyanin, total antioxidant, rice analog, baruk sago, purple sweet potatoes

Abstract

ABSTRACTOne effort to improve food security, namely through the product development process that does not depend on the type of material, but by utilizing local material sources. Purse can be processed into flour for having carbohydrate, protein, fat, with huge potential to be developed and processed into various products sala sole bread. The bread is usually made of wheat flour because it contains gluten. In the purse flour has no gluten so it is used as a substitute. The purpose of this study was to determine the effect of starch concentration purse on the level of development, porosity and quality of the bread and analyze the level of consumer acceptance and chemical analyzes of bread flour purse.This study uses a completely randomized design (CRD). each treatment was performed 3 (three) times repetition with variation flour purse 0% (control), 30%, 50%, 70%, in each treatment and observation of the level of development, porosity, water content, ash content, protein, fats, carbohydrates, and organoleptic test of the level of preference. Results showed the sample A with concentration (Flour 70%: 30% flour purse) has a level of development 2,8cm, porosity 31, the water content of 31.85%, ash content of 1.26%, 4.39% fat content, content 7.02% protein, and carbohydrate content of 54.57% and the highest color organoleptic value of 3.55, 3.50 odor, flavor and texture 3.50 3.40 most preferred panelists. Flour substitution berpengaru purse in high concentrations significantly affected the level of development, the porosity, the quality of bread and panelist preference level, while on the chemical analysis of water content, fat, protein, and carbohydrate, ash content decreases and increases.Keywords: Bread, Gluten, Wheat purse, Wheat Flour.
