Abstract

Kefir is one of the functional beverages that has an acidic taste due to the activity of lactic acid during the fermentation process. One of the ingredient innovations for kefir was soy milk, skim milk and variations of sugar types. Soy milk protein has an amino acid structure similar to cow's milk, so it is very good for people with lactose intolerance. The aim of this study is to know the quality (total of lactic acid and the organoleptic quality) of the kefir combination between soy milk and skim milk on the variation of sugar and fermentation duration. The study used experimental methods and complete random design (CRD) with two factors. Factor I was the sugar variation (N) palm sugar and white sugar. Factor II was the variation of fermentation duration (K) 24 hours, 36 hours, and 48 hours. The results of the study showed that the lowest lactic acid of kefir combination between soy milk and skim milk was 0.896 % on N2K1 treatment (white sugar + 24-hour fermentation duration). The best organoleptic quality of kefir combination between soy milk and skim milk was N2K1 white sugar + 24-hour fermentation duration) in white color, sour taste, and soft texture.

Abstract

Kefir is a probiotic bevarage produced by live lactic acid bacteria. One of the innovative ingredients for kefir is goat's milk, skim milk, and variations of sugar (cane sugar and palm sugar). The nutritional content of goat's milk is 2.2% protein, 14.7% fat, and 3% fiber, and 4.80% lactose. The addition of skim milk in the manufacture of kefir can increase the total sugar content. The addition of sugar as a source of nutrition for kefir grain starter bacteria. The purpose of this study was to quality of kefir combination between of goat’s milk and skim milk on variations of sugar and fermentation duration. This study used an experimental method and a completely randomized design (CRD) with two factors. The first factor is the variations of sugar (A) palm sugar and cane sugar. Factor II (B) is the variations of fermentation duration for 24 hour, 36 hour, and 48 hour. The results showed that the best total kefir acid content combined with goat milk and skim milk was 0.797%, pH 4 in the A2B1 treatment (30 g cane sugar + 24 hour of fermentation duration). The best organoleptic quality was in the A2B1 treatment (30 g cane sugar + 24 hour of fermentation duration) with a sour taste, white color, tasty flavour, and soft texture.

Abstract

Herbal tea combination between corn silk and stevia leaf is a functional drink for health and refreshment. Corn silk contains antioxidant compounds or flavonoids that lower blood glucose levels. Stevia leaf as a natural sweetener contain stevioside, rebaudioside A, rebadioside C, and dulcoside A which are 200 to 300 times sweeter than sucrose. The aim of this study was to know the levels of glucose, antioxidant activity, and organoleptic quality of herbal tea combination between corn silk and stevia leaf with variations of temperature and drying duration. The study used experimental methods and a complete random design (crd) of two factors, factor I drying temperature 45 °C and 50 °C, factor II drying duration 2 hours and 4 hours. The results of the study showed the highest glucose of herbal tea combination between corn silk and stevia leaf on S2L2 (drying temperature 50 °C and drying duration 4 hours) is 7,212 g/100 g. The optimum antioxidant activity and best organoleptic quality of herbal tea on S1L1 (drying temperature 45 °C and drying duration 2 hours) was 83,696 % and yellow color, sweet taste, herbal tea characteristic scent, and respectively.

Abstract

The probiotic beverage tepache is a variety of natural or processed functional products that contain bioactive compounds with specific physiological functions for health. Pineapple peel is one of the plant base ingredients that can be used as a base for probiotic beverages. The levels of antibacterial compounds, carbohydrates, and sugars in pineapple peel are sufficient to be an essential medium for the growth of Lactic Acid Bacteria (LAB) in probiotic beverages. This research was aimed to determine the glucose levels and organoleptic quality of probiotic beverages tepache of pineapple peel on variation of sugar and fermentation duration. This research used experimental method Completely Randomized Design (CRD) with two-factors, Factor 1 was variation of sugar (G) palm sugar and granulated sugar. Factor 2 was the variation of fermentation duration (F) 3 and 5 days. The results of the research showed that the tepache of pineapple peel had the highest glucose levels in the treatment of G1F1 (palm sugar 100 g with 3-days fermentation duration) at 12,2 %. The best organoleptic quality of tepache pineapple peel was in G2F1 treatment (granulated sugar 100 g with 3-days fermentation duration) with light yellow color, tepache-specific aroma, and sour flavor.

Abstract

Corn silk has high antioxidant activity so that with a combination of mint leaf it can be made into herbal tea which is beneficial for health. This research aims to determine the antioxidant activity and organoleptic quality of herbal tea combination between corn silk and mint leaf in a variations of temperature and drying duration. The method in this research used a completely randomized design (CRD) with 2 factors, factor 1 were drying temperature (J) (45 °C, 50 °C, and 55 °C) and factor 2 were drying time (K) (2 hours and 4 hours). The results of this study showed that the highest antioxidant activity of the herbal tea combination between corn silk and mint leaf on J₁K₂ treatment (temperature 45 °C and drying time 4 hours) of 85.375 %, while the best organoleptic quality of herbal tea between corn silk and mint leaf was in the J₁K₁ treatment (temperature of 45 °C and drying duration of 2 hours) with a fresh taste, mint tea aroma, and yellowish color.

Abstract

Natural flavoring is a flavoring made from edible mushrooms as a flavor enhancer food of powder or liquid form. Ear mushrooms and shrimp heads contain high protein and glutamic acid and can be used as natural flavoring and give additional savory taste of food. The objective of this research was to analyze the total protein content and organoleptic quality of natural flavoring components of ear mushrooms and shrimp heads at various drying temperatures. This research method used a completely randomized design (CRD) and two treatment components. The first component was the ratio of ear mushroom and shrimp heads: (25g:75g), (50g:50g), and (75g:25g). The second component was different drying temperatures of 40°C and 50°C. The research results showed that the highest content of total protein and the best organoleptic quality of natural flavoring in the K1T2 treatment (25g ear mushrooms + 75g shrimp heads with 50°C drying temperature) was 35.67% ie dark brown color, savory taste, delicious aroma, very soft texture, and liked.
