Abstract

Industri opak di Pancur Batu ini masih belum menggunakan kemasan untuk memasarkan opaknyasehingga sangat mudah terkontaminasi dan menyerap air kembali kalau udara sekitarnya lembab.Pengeringan juga masih penjemuran langsung dengan matahari.Untuk mengatasi persoalan diatas,perlu dilakukan perbaikan proses pengeringan opak dan diikuti dengan pengemasan opak yangakan dipasarkan. Penerapan iptek yang dilakukan yaitu penjemuran langsung matahari digantisecara bertahap dengan pengeringan surya. Pengemasan dilakukan dengan menggunakan plastikyang di paking. Pengeringan opak dengan alat pengering surya dan penjemuran matahari dilakukan pengukuran laju pengeringannya dengan waktu 8 jam dihasilkan opak dengan kadar air masing-masing sebesar 7,6 % dan 9,56%. Setelah 2,5 bulan penyimpanan dengan metode pengemasan yang berbeda opak tersebut dianalisa. Kadar air masing-masing menjadi 11,98% untuk opakyang dikemas dengan pelastik dan 13,72% untuk opak yang dikemas dengan goni biasa. Kadarabu adalah sama sebesar 2,16 (%bk) dan TPC masing-masing sebesar 67,86 dan 95,42koloni/gram. UKM telah memproduksi dan menjual opak ukuran kemasan 200 g dijual dengan hargaRp 2.000,- ukuran 500 g dengan harga Rp 4500,- dan ukuran 1000 g dengan harga Rp 9.000,-.Sangat berbeda jika UKM menjual dengan kemasan goni opak dijual dengan harga Rp 7000,- perkg. Terjadi Peningkatan nilai jual Rp 2.000,-/kg. Pemasaran opak kemasan pelastik UKM perminggu100 kg, jadi kalau penjualan perbulan mencapai 400 kg maka akan diperoleh harga penjualan Rp800.000,-. Jika biaya kemasan 10% dari harga jual yaitu sebesar Rp 360.000,-, akan diperoleh nilaitambah sebesar Rp 440.000,- perbulan.

Abstract

Wastewater from starch processing of purple sweet potato (PSP) was rich in anthocyanin, so it can be used as raw material for natural pigments. Anthocyanin pigments are unstable under processing conditions so microencapsulation is carried out to maintain their stability. This study aims to evaluate the effect of maltodextrin concentration as an encapsulant agent on the physical and chemical characteristics of microencapsulant of anthocyanin derived from wastewater of PSP starch processing. Wastewater from PSP starch processing was concentrated using a water bath at 10 oC for 10 hours.  The crude extract of anthocyanin obtained then was microencapsulated by spray drying technique using maltodextrin as an encapsulant agent. Maltodextrin was added at concentration 15%, 25%, and 35% (w/w). The anthocyanin microencapsulants produced then were evaluated for their physical and chemical characteristics. The results showed the increasing of maltodextrin concentration will increase the L* value (lightness), b* value (greenness), ohue, solubility, hygroscopicity, but decrease the anthocyanin content, a* value (redness) and and antioxidant activity (IC50). The microstructure of anthocyanin microencapsulant has a spherical shape with a curve on its surface. The addition of 15% maltodextrin produces the best characteristics of anthocyanin microencapsulant with anthocyanin content 40.80 ppm, IC50 36.27 ppm, solubility 52.80% and color value (oHue) 11.17 (red purple). These characteristics indicate that anthocyanin microencapsulant from wastewater of PSP starch processing can be applicated as natural food colorant.Keywords: anthocyanin microencapsulant, purple sweet potato, wastewater, maltodextrin

Abstract

The bakery industry is one of the food industries that continues to increase along with the increase in income and changes in people's lifestyles. Increasing the number of bakery industries has an impact on the increasing demand for wheat flour, which in turn can threaten national food security. Faidah Catering Service and Baraqah Q Snack, Cake and Cookies are SME partners engaged in bakery industry in Binjai City. Based on the situation analysis, the problems of both SMEs are low production capacity and competition in the marketing. The use of wheat flour as the raw material makes their products become same as the products produced by other SMEs. The simple processing equipment causes a low production capacity. The proposed problem-solving method for SME partners is product diversification through the use of local tubers in the form of cassava flour and sweet potato flour as raw material. Increased production capacity is carried out by giving and training the use of production equipment in the form of dough mixers and oven grills with large capacity. The results of the activity indicate that the diversification of cake products and cookies using non-flour flour raw materials can be accepted by consumers and increase marketing.
