Bangkit cookies are composed entirely of sago flour, which contains a high carbohydrate but low protein content. Tempeh flour's high protein content is expected to enhance the protein content of the cookies. In addition, the usage of emulsifier will also be expected to improve the texture of the bangkit cookies. This study aimed to determine the best type of tempeh flour for various kinds of beans, i.e., soybeans, green beans, and red beans, based on their highest protein content and to identify the best ratio of tempeh flour to sago flour and the type of emulsifier in the bangkit cookies formula based on their texture and sensory acceptance. This research was divided into two stages. The first research stage used a Completely Randomized Design with 1 factor (soybeans, green beans, and red beans). The second stage of research used a Completely Randomized Design 2 factors (ratio of soybean tempeh flour:sago flour 0:100, 80:20, 60:40, 40:60) and types of emulsifier (egg yolks, soy lecithin, monoglyceride). Research result shows that 80:20, 60:40, and 40:60 ratios of sago flour to soybean tempeh flour with egg yolk emulsifier, soy lecithin, and monoglyceride, increased the protein content by an average of 7.15-21.53% and increased the hardness value of bangkit cookies. The best bangkit cookies are made from the ratio of sago flour and soybean tempeh flour 80:20 with egg yolk emulsifier and meet the SNI of cookies, which have 4.14% of moisture content, 8.95% of protein content, 622.99 hardness, and 3.7 of taste scored which is closest to the control.","PeriodicalId":126879,"journal":{"name":"AGRITEKNO: Jurnal Teknologi Pertanian","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124807492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The syrup is a processed product made from sugar and water, with a minimum sugar moisture content requirement of 65%. The syrup is made from yellow pumpkins with food additives such as sugar, carboxyl methyl cellulose, citric acid, and lime. Variations in concentrations of sugars between 65% and 70% and citric acid between 0%, 0.1%, 0.3%, and 0.5%, are expected to affect pH, total dissolved solids, reduction sugars, vitamin C, and beta-carotene. The research objective was to study and determine the effects of cane sugar and citric acid concentrations on pumpkin syrup's physical, chemical, and organoleptic properties. pH, total dissolved solids, reducing sugars, vitamin C, and beta-carotene content were measured using a pH meter, a hand refractometer, the Nelson-Somogyi method, the iodometric method, and the spectrophotometer method, respectively, and organoleptic properties were evaluated using the sensory test. Results showed that variations in the addition of sugar and citric acid had a pH of 3.46-6.00, total dissolved solids 10.33-11.4 (obrix); reduction sugars of 19.4%-30.21%, vitamin C of 20.53-38.13 (mg/100 g); and beta-carotene of 1.24-2.82 mg/100 g.

The COVID-19 pandemic has also raised awareness of the need to continually strengthen the immune system. Increasing the body's resistance can benefit from the use of traditional herbs with medicinal capabilities. Some biological plants such as red ginger, alang-alang root, galangal which are known to the public for their spices, can become herbal drinks when formulated with the addition of palm sugar. These three plants have been studied on a laboratory scale to identify nutrients and bioactive compounds that are beneficial for health. The purpose of this study was to determine the nutritional content of functional herbal drink products made from palm sugar and spice powder (red ginger, alang-alang root, and galangal). The research method was carried out using hedonic organoleptic tests on 3 prepared formulas, phytochemical screening, and proximate test (nutritional content) The results of the organoleptic test showed that respondents preferred a formula containing ginger (500 g), alang-alang root (200 g), galangal (100 g,) and palm sugar (200 g). Phytochemical screening showed each component (ginger, galangal, alang-alang, palm sugar, and the developed formula) was positive for flavonoids and alkaloids. Only ginger was positive for tannins, all negative components were steroids/triterpenoids and only galangal was positive for saponins. Carbohydrate, protein, fat, moisture, and ash contents were 4.49%, 4.38%, 3.95%, 47.68%, and 9.76%.

This objective of the study was to determine the best pectin extraction temperature which ranged from 70°, 80°, to 90℃ and the effect of edible coating of pectin extracted from kepok banana peel on the shelf life of tomatoes. Observation of the shelf life of tomatoes was carried out by observing weight loss and vitamin C content in tomatoes. The pectin extraction process and physiological characteristics of tomatoes were studied quantitatively for this study, and the physical characteristics of tomatoes were studied qualitatively throughout the course of 21 days.
