Daun kangkung mengandung pigmen klorofil yang dapat dimanfaatkan sebagai pewarna alami untuk makanan. Ekstrak pekat pigmen klorofil dari daun kangkung merupakan bahan yang sangat kental sehingga agak sulit dan kurang praktis dalam penggunaannya. Hal ini dapat diatasi dengan manggunakan teknik mikroenkapsulasi sehingga mempermudah penggunaan dan meningkatkan umur simpannya. Bahan penyalut yang digunakan untuk mikroenkapsulasi ekstrak pigmen klorofil ini adalah dekstrin dan gum arab. Metode yang digunakan pada penelitian ini adalah deskriptif dengan 6 perlakuan dan 2 kali ulangan. Perlakuan yang digunakan adalah penggunaan bahan penyalut dekstrin dengan konsentrasi 5%, 7,5%, dan 10% (b/v) dan gum arab dengan konsentrasi 5%, 7,5%, dan 10% (b/v) dari total volume bahan. Hasil penelitian menunjukan penggunaan bahan penyalut dekstrin dengan konsentrasi 10% (b/v) menghasilkan bubuk pigmen klorofil dari daun kangkung dengan karakteristik terbaik, yaitu memiliki nilai intensitas warna hijua (nilai a) yaitu -19.97, nilai HUE 127.42 (melefleksikan warna kuning kehijauan), rendemen 2.99%, kadar air 1,80%, kelarutan 97.48%, waktu rehidrasi 36.4 detik, dan nilai pH 8,1.

Concentrated extract of chlorophyll pigment from kale leaves is a very thick material that is rather difficult and less practical in its use. This can be overcome by using microencapsulation techniques so as to facilitate use and increase shelf life. The coating material used for microencapsulation of chlorophyll pigment extract is dextrin and arabic gum. The method used in this study is descriptive with 6 treatments and 2 repetitions. The treatment used was the use of dextrin coating material with a concentration of 5%, 7.5%, and 10% (b/v) and arabic gum with a concentration of 5%, 7.5%, and 10% (b / v) of the total volume. ingredients. The results showed that the use of dextrin coating material with a concentration of 10% (w / v) produced chlorophyll pigment powder from kale leaves with the best characteristics, which has hijua color intensity value (a value), namely -19.97, HUE value 127.42 (reflecting greenish yellow), yield 2.99%, water content 1.80%, solubility 97.48%, rehydration time 36.4 seconds, and pH value 8.1.

This study aims to determine the total lactic acid bacteria, total acid, pH value, syneresis, and organoleptic properties of yogurt using the back slooping method. Experiments were made by taking bacteria from yogurt products (biocul) with variations in the incubation time of room temperature, 37 oC, 40 oC, 45 oC, and 37 oC to 40 oC. The results of the analysis on total lactic acid bacteria, total acid, pH value, and viscosity of yoghurt with the back slooping method gave different results. Meanwhile, the organoleptic test used the hedonic level of preference, which included aroma, color, texture, and overall acceptance. Total lactic acid bacteria 8,03-8,29 log CFU / ml; total acid 0.95-1.26%; pH value 3.70-4.78; total dissolved solids 10.1-12.0%; Organoleptic test with the level of preference including color, aroma, texture and overall acceptance, obtained a preference score of 4, which means like. Based on the organoleptic test, it can be concluded that the best quality of yogurt with the back-loop method of incubation temperature of yogurt B5 with an incubation temperature of 37 oC to 40 oC

Cheese is a product of milk, mostly imported from other countries. Therefore it is very important to develop using locally available materials. This study was conducted to compare the effects of a given treatment. Soft cheese composition made from cow's milk using direct pickling techniques. This research used fresh cow's milk from Lampung State Polytechnic, LAB starter from “biokul” brand and rennet as a coagulant. The treatment consisted of 2 treatments, namely making cheese with the addition of rennet and adding rennet + starter LAB. The variables measured were yield, aroma, taste, and overall appearance. The results showed that the direct acidification technique using the LAB starter is feasible for use in the process of making soft cheese from cow's milk. The advantage of this technique is that it is fast, easy and cheap. The yield and composition of soft cheese from cow's milk varies depending on the treatment at the time of cheese making. To produce soft cheese with high yield, good aroma, taste, and overall appearance, it is recommended to use the rennet + starter LAB treatment.
