Abstract

The main ingredient of ice cream is cream. Regularly, ice cream is made from animal fat of milk, but can be made from vegetable fats as well. Coconut milk as a source of vegetable fat (cream) can be an alternative substance for making ice cream and is suitable for people with lactose intolerance. Making coconut ice cream requires a gelling agent dissolved in ice cream mixture (ICM). Corn starch that was modified physically (RS type 3) can be used in making of coconut ice cream which functions as a gelling agent. The research purpose was understanding of how to make coconut cream which can produce an overrun quality and organoleptic (hedonic) test. The study was conducted in a laboratory scale with a completely randomized design (CRD) with 4 variations in the proportion of the addition of this resistant starch and 3 replications which were tested for analysis of variant (ANOVA) and further tests with the Duncan and Kruskal Wallis multiple distance test. The results showed that the addition of resistant starch had an effect on the overrun significantly with the highest value of 23.53% at the 5% level of the proportion of ingredient. The hedonic test for the coconut ice creams at the proportion of ingredient was 5% as the highest score observed by the panelists whose the score was not significantly different from the proportions of the ingredients 3% and 6%.

Abstract

Strawberry merupakan buah yang sudah banyak dikembangkan di Indones. Strawberry banyak dibudidayakan di daerah yang memiliki dataran yang tinggi, seperti Lembang, Ciwidey, Sukabumi, dan Cianjur. Warna merah yang menarik dari strawberry dihasilkan dari kandungan senyawa antosianin yang terkandung di dalamnya. Proses ekstraksi pada senyawa antosianin dipengaruhi oleh pelarut yang digunakan serta lamanya ekstraksi. Tingginya kandungan antosianin pada buah strawberry berkorelasi dengan semakin kuatnya aktivitas antioksidan pada buah strawberry dalam menangkal radikal bebas. Buah strawberry memiliki kelemahan diantaranya mudah rusak, selain itu senyawa antosianin yang sudah diekstrak mudah mengalami kerusakan karena sifatnya yang tidak stabil, sehingga perlu dilakukan tindakan lebih lanjut diantaranya proses esnkapsulasi. Proses enkapsulasi merupakan proses perubahan ekstrak antosianin dari bentuk cair ke bentuk serbuk menggunakan bahan penyalut, salah satunya adalah maltodekstrin. Serbuk antosianin ini bisa dimanfaarkan sebagai pewarna, pengawet, dan bahan tambahan pangan untuk meningkatkan antioksidan yang aman pada makanan.

Abstract

Utilization of aluminum metal powder waste left over from the plate rack which is wasted can apparently provide economic value as raw material for making coagulants. Aluminum powder waste contains 88.74% aluminum. The high aluminum content makes plate rack waste potentially as raw material for the manufacture of polyaluminium chloride (PAC). This study begins with the manufacture of AlCl3 monomers on 4 grams of aluminum metal weight, by varying NaOH concentrations (44, 45, 46, 47 and 48%) and variations in HCl concentrations (31, 32 and 33%). Next the AlCl3 monomer is converted to PAC polymer. The results on variation of 48% NaOH and 32% HCl with pH 3.6 and specific gravity 1.23 g / ml. This result is in accordance with SNI 06-3822-1995 quality standards. This study also tested the ability of PAC to reduce turbidity in well water, with a pH of 4.30 and a decrease in turbidity of 94.94%. Can produce PAC that is more economical and has met the standard qualityof conventional SNI PAC.
