AbstractThis work consists of a study about the influence of the fermentation methods on the resistant starch (RS) formation. Crystalline phases at the white bread after production and during the staling were evaluated. The bakery formulation was proportionally the same for the two fermentation methods used, except for the yeast. A commercial dry yeast and sourdough were used for the direct method (DM) and indirect method (IM), respectively. The temperature and cooking time, as well as the packaging and storage, were kept constant for all samples. Characterizations were performed on both samples by XRD and FTIR-ATR. It is possible to affirm that the fermentation method greatly influences the crystalline and microstructural properties of bread, mainly on the RS. The bread produced by IM presented more significant changes in its microstructure and degree of crystallinity than bread made by DM. These microstructural differences may be directly related to the microorganisms present in the sourdough, which can influence the bread resistant starch during the cooking and storage time.

ABSTRAKIkan patin merupakan ikan air tawar yang mengandung lemak dan protein tinggi sehingga apabila dilakukan penyimpanan rentan terjadi oksidasi yang mengakibatkan ketengikan. Sargassum sp. dengan kandungan fenol dan flavonoid mampu menghambat terjadinya oksidasi pada fillet ikan patin. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan ekstrak Sargassum sp. dan lama penyimpanan dalam menghambat terjadinya oksidasi pada fillet ikan patin. Materi yang digunakan dalam penelitian ini adalah ekstrak Sargassum sp. dan fillet ikan patin. Metode penelitian yang digunakan adalah experimental laboratories dengan menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor yaitu konsentrasi ekstrak Sargassum sp. (0%, 1%, 1,5% dan 2%) dan lama penyimpanan (hari ke-0, hari ke-2, hari ke-4, dan hari ke-6. Hasil penelitian menunjukkan bahwa perbedaan penambahan konsentrasi ekstrak Sargassum sp. dan lama penyimpanan memberikan pengaruh nyata terhadap nilai PV, nilai TBA, kadar lemak, kadar protein, kadar air serta organoleptik (P < 0,05). Hasil penelitian tahap I didapatkan rendemen Sargassum sp. dengan pelarut etanol 96% sebesar 1,39%, kandungan fenol 1,813%, flavonoid 0,278% dan aktivitas antioksidan 99,1659 ppm (kuat). Hasil penelitian tahap II didapatkan nilai PV berkisar antara 2,03 - 19,82 meq/kg, nilai TBA 0,63 - 6,72 mg.mal/kg. Konsentrasi 1,5% merupakan konsentrasi terbaik ekstrak Sargassum sp. dalam menghambat oksidasi lemak pada fillet ikan patin selama penyimpanan.Kata kunci: Antioksidan, Ekstrak Sargassum sp., Lama Penyimpanan, Oksidasi lemak, Fillet Ikan patinABSTRACTCatfish is a freshwater fish that contain high fat and protein so that if its stored it will susceptible to oxidation process which leads to rancidity. Sargassum sp. with its phenolic and flavonoid content are able to inhibit the oxidation process in catfish fillet. This research was aimed to know the effects of different concentrations of Sargassum sp. extracts and storage time in inhibiting the oxidation process in catfish fillet. The materials used in this research were Sargassum sp. extracts and catfish fillet. This research was using experimental laboratories research method with factorial Completely Randomized Research Design (CRD) of 2 factors which were concentrations of Sargassum sp. extracts (0%, 1%, 1.5%, and 2%) and storage time (0 day, 2 days, 4 days, and 6 days). The results showed that the adding of different concentrations of Sargassum sp. extracts and storage time gave significant effect to the PV value, TBA value, fat content, protein content, moisture content, as well as organoleptic point (P < 0.05). The results obtained from stage I research were the yields of Sargassum sp. with ethanol 96% solvent was 1.39%, phenol content was 1.813%, flavonoid was 0.278%, and antioxidant activity was 99.1659 ppm (categorized as strong antioxidant). The results obtained from stage II research were the PV value were ranged from 2.03 to 19.82 meq/kg, TBA value were ranged from 0.63 to 6.72 mg.mal/kg. The 1.5% concentration was the best concentration of Sargassum sp. extracts in inhibiting the lipid oxidation of catfish fillet during storage.Keywords: Antioxidant, Sargassum sp.

The effect of different composite coatings on quality of semi-moist apricot cubes mixed with cornflakes was investigated during 180 days of storage. The apricot cubes were osmotically dehydrated (OD) and coated before hot-air drying (HAD) at 60 °C. Chitosan-bees wax (CBW) and whey protein isolate-bees wax-oleic acid (WPI-BW-OA) coatings were applied after HAD and the samples were added to cornflakes. Application of OD and pectin-ascorbic acid (Pec-AA) coating (prior to HAD) and WPI-BW-OA coating (after HAD) led to significant retention of total phenol compounds, β-carotene and antioxidant activity in apricot cubes compared to uncoated and CBW-coated samples. WPI-BW-OA-coated samples gave significantly higher L* values (lighter color) and b* values (more creamy or yellowish color) and lower a* values (less reddish color) and browning values than control followed by CBW-coated apricots at any time of storage (p < 0.05). The rate of apricot moisture loss and cornflakes moisture gain was higher in uncoated apricot cubes, followed by CBW- and WPI-BW-OA-coated samples. Application of WPI-BW-OA coating was effective in retaining the crispness measured by lower firmness (Fmax) values in cornflakes upon storage. Based on the obtained results, WPI-BW-OA coating allowed effectively preserving the quality characteristics of semi-moist apricot cubes and cornflakes components in the mixed state.
