Abstract

Beluntas  (Pluchea  indica  Less)  is  a  herb  that  commonly  used  as  traditional medicine  and  food.    Its  leaves  have  many  biological  activities,  because  they  contain various  phenolic  compounds.  The  phenol  concentration  of  beluntas  leaves  depends on leaf segment, earth condition, fertilizer and environmental stress.  This research is focused  to  determine   antioxidant  activity  of  three  groups  of    beluntas  leaf  segments that   includes 1-3, 4-6 and > 6.  They were ground, dried at ambient temperature for  7  days, maserated by petroleum eter (1:4 b/v) at ambient temperature for 24 hours and soxhlet  extracted  by  methanol  (1:15  b/v)  at  65oC  for  3   hours.  The  result  shows  that the  extract  contains  phytochemical   compounds  such  as  tannin,  sterol,  phenol hydroquinone  and  flavonoid.  This  extract  has  antioxidant  activity  to  scavenging  free radical  DPPH   (2,2-phenyl-1-picrylhydrazyl).  The extract of  1-3  beluntas  leaf  segment  was   more  potential  antioxidant  source  than  4-6  and  >  6  beluntas  leaf   segments,  because it had the least IC50 (inhibitor concentration) and the  highest total phenol and  total flavonoid. The IC50, total  phenol and flavonoid  total of  it were 3.71 mg/L,  234.65  mg GAE/100 g samples  and 2163.59 mg QE/ 100 g samples, respectively.

Abstract

Gelatin is  a natural  product obtained by hydrolysis  of collagen, a soluble protein, which acts  as the  gelling agent. In  general, the  process  of making gelatin begins  with soaking the bone  in  acid  solution,  aimed  at  dissolving  calcium  phosphat  and  other  mineral  salts.  This treatment resulted  in changes to the texture bone , so that bones become relatively non-rigid. Type of acid used is strong acids, namely HCl, H2SO4 and H3PO4, with the level of 3% - 6% concentration. The  purpose of  this  study  was to determine  the  type and  concentration  of acid as a soaking solution. The result showed that the best treatment was HCL concentration of 3%, with  water  content  6.54%,  ash  3.27%, 77.92% protein, gel  strength 72.07  bloom, viscosity 17.86 cp, pH 4.88 and  yield 14.03%. Key words : gelatin, collagen, bone, hydrolysis

Abstract

Sinbiotik  (eubotic)  is  a  combination  of  prebiotics  and  probiotics.  The  advantage  of  this combination is to enhance  the growth  of  probiotic  bacteria  by prebiotic  substrates. In general, the  raw  material  of  sinbiotik  beverage  is  milk.  At  this  time,  as  product  innovations  made  brew filtrate  sinbiotik  of  yam  tubers  (Pachyrrizus  erosus).  The  advantages  of  this  product  is  the availability of two components as well as the  inulin derived from the  tubers of  yam which acts as a prebiotic and Lactobacillus Casei that act as probiotics. The purpose of this study was to determine the effect of the addition of skim milk and the concentration of starter (Lactobacillus casei)  that  most  optimally  in  the  process  of  making  drinks  sinbiotik  yam  tubers.  The  results showed  that  the  best  treatment  there  is  the  additional  treatment  of  skim  milk  20%  and  the concentration of starter (Lactobacillus Casei) 2%. The results showed total lactic acid bacteria 11.2933 log CFU / ml, 0.5119% total acid, pH 3.7, total dissolved solids 36.0680 (oBrix), inulin content of 3.2503% and 0.3667% soluble protein.Keywords: sinbiotik, skim milk, probiotic bacteria, prebiotic substrates

Abstract

The  oxidative  browning  is  considered  to  have  a  contribute  to  the  flavor, antioxidative activity and color of food. As a result of this Maillard reaction, a variety of by  products,  intermediates  and  brown  pigmens  (melanoidins)   are  produced.  The objectives  of  this  research  was  to  study  the  effect  of  antioxidant  activity  method determination on model and soysauce. The soy  sauce were prepared from sucrose or  coconut  sugar    and  moromi.  The  soysauce  and  model  were  fractionated  by  ultrafiltration in a molecular weight ranging between 10 kDa to 100 kDa. In this study, we  report  that  fractions  of  soysauce.  and  model  have  the  ability  to  scavenging  more strongly DPPH  radical on the fraction with molecular weight of 30 kDa  than 100 kDa,  whereas   the  inhibition  of  oil  oxidation    was  stronger  in  the  fraction  with  molecular  weight <10 kDa to 30 kDa and its activity is more greater than BHT 200 ppm,  although the effect of antioxidants in  soy sauce is greater than the model. Each  fraction of soy sauce  and  a  model  had  a  specific  effect  on  the  inhibition   method  of  oil  oxidation    or sscavenging of  free radicals

Abstract

Chili powder is a product in the form of powder, practically in the preparation and have a long shelf life. This is the nature of the powder product having a very small particle size, has a  low  water  content.  Chili  powder  manufacturing  process were sorting,  washing  and  cleaning the stem, drying, milling and sieving. This study aims to find the best results from different  type of chili with different dryers include: Oven,  Freeze Dryer and  Cabinet dryer  on the quality of  red  chili  powder. Tthe  results  obtained  from  the  data  the  best  treatment  of  red  chili  powder using a freeze dryer  as follows: The water content of 15.8679%, β-carotene  318.728  IU, vitamin C 563.017 (mg/100g), color (L * 42.40; 20.25 b * 18.60) and organoleptic tests of color (83.5).Keywords : chili powder, cabinet drier, oven, freeze drier

Abstract

Several types  of  seaweed in  Bali  has  been generally  consumed  by  local  people  as vegetable, such as Caulerpa spp. (local name Bulung Boni), Gracillaria spp (local name Bulung Sangu) and Euchema spinosum, but has not been reported  its potential effect to increase high density  Lipoprotein  (HDL)   levels.  Therefore it  is  necessary    to  determine  of  plasma HDL cholesterol  level  of  Wistar  rat  after  treated  Caulerpa  spp,  Gracillaria  spp. and  Euchema spinosum. This experimental study used completely  randomized design. Research using  a total of  32  Wistar rats  divided  into  eight  sample  groups  of  equal  size,  all  fed  with  a  diet  high  in cholesterol content. The eight sample groups were respectively designated as negative control group,  positive  control  group,  and  six    treated  sample  groups,  respectively  fed  orally  with  a dose of 1 g and 1,5 g seaweed flour  of Caulepa spp.  1g and 1,5 g of Gracilaria spp., and 1 g and  1,5  g  Euchema  spinosum  per  100g  body  weight  per  day.  Each  treatment  was  repeated four times.  Our  study showed  that  rat fed with  high  cholesterol  diet and  treated Caulerpa  spp., Gracilaria spp., and E.spinosum with a dose of 1 g and 1.5 g/100 g body weight rat / day were associated  with  statistically  significantly  increased plasma HDL level (p  <0.05) as compared with those  of rats fed with high-cholesterol diet without treated  Caulerpa spp., Gracilaria spp., and E.spinosum. The  studied  concuded  that  plasma  HDL  level  of  Wistar  hypercholesterolemia  fed Caulerpa  spp.,  Gracilaria  spp.,  and  E.spinosum  flour with  dose  of  1  g  or  1,5  g higher  than Wistar rat without treated seaweeds flour. Rats fed E.spinosum with dose of 1.5 g , the plasma HDL level highest than the other treatment.Keywords : Caulerpa spp., Gracilaria spp.,  E.spinosum, HDL,  hypercholesterolemic

Abstract

A  study  on  the  effect  of  processing  on  resistant  starch  (RS)  content  of Breadfruit  (Artocarpus  altilis  Park)  has  been  conducted.  The  aim  of  this research was to evaluate a resistant starch formation in pre-cooked flour made of breadfruit using different processing methods. The principle of preparing the pre-cooked  flour  is  improving  retrograded  starch  content  which  is  a  kind  of resistant starch (type 3) The processing included boiling, steaming, and frying, and  each  processing  was  combined  with  cooling  for  24  hours  in  refrigerator, prior to drying, milling and shieving.  It  was  found  that  processing  (combination  of  heating  and  cooling)increased  Resistant  Starch  (RS)  content  of  breadfruit.  Boiling  and  cooling changed RS from 3.27%to 3.82% (16.8%),  steaming and cooling changed RS from 3.27% to 6.67%  (103.9%) and frying and cooling changed RS from 3.27% to  3.68%  (12.5%).  Pre-cooked  flour  from  the  best  treatment  (steaming  and cooling)  was   tried  to  be  applied  in  making  of  biscuit,  cakes  and  sweet  bread (with   various  formulation).  The  products  prepared  by  substitution  with  pre-cooked flour (until 30%) were preferred by the panels in term of color, taste  and texture and they have medium resistant starch content (2,5-5,0%), so that  they can be developed as the kind of functional food.Key  words  :  breadfruit,  processing  method,  pre-cooked  flour,  resistant  starch(RS), functional food
