The objective of this experiment was to develop novel restructured products from fresh avocado fruits puree and calcium-alginate gel forming method (internal setting). Gel forming by internal setting the calcium is released under controlled conditions simultaneously throughout the system. Restructuredfruit products were evaluated for pH, color, and sensory properties. Sodium chloride (0.5% and 1.0%) did not give better flavor for restructured avocado compare to product without it. The addition of sodium chloride precisely increases the sourness of the product. Restructured avocado product with citric acid concentration 0.05% and 0.1% were much preferred than product with citric acid concentration 0.5%. The addition of sugar (5%) to the restructured product significantly reduced the sourness. Compared to the addition of sodium chloride (0.5%), products with addition of sugar (2.5% and 5%) were significantly more preferable and the flavors were closer to fresh-cut avocado fruit.

Upon peeling and slicing fresh fruits are easily discolored due to enzymatic reaction in the presence of oxygen. Restructured fruit also suffer the discoloration during aerobic storage either at room temperature or under refrigeration. The objective of this study was to find alternatives for preventing or retarding the discoloration rate of calcium-alginate restructured fruits during aerobic refrigerated storage using anti browning additives. Four different fruits including avocado, mango, jack fruit, and soursop were restructured using sodium alginate (1% w/w) and calcium lactate (1% w/w). The additives tested were citric acid 0.5% (w/w), ascorbic acid 0.05% (w/w), sodium disulfite 0.01% (w/w), N-acetyl-cysteine 0.05% (w/w), and combination of citric acid 0.05% (w/w) and N-acetyl-cysteine 0.05% (w/w). Addition of anti browning additives at the specified concentration was effective in delaying the discoloration of restructured fruits during aerobic storage at 4ºC for up to 6 days. Among the additives tested the use of combination of citric acid 0.05% (w/w) and N-acetyl-cysteine 0.05% (w/w) was the most effective in retarding the discoloration across the fruits. Restructured soursop, in particular, was not undergoing significant sidcoloration for 11 days of refrigerated storage.

Karakter Fisik dan Sensoris Produk Hasil Restrukturisasi Buah Nangka (Artocarpus heterophylla L.) dan Sawo (Manilkara achras (Mill.) Fosb) Selama Penyimpanan Beku Sri Raharjo; Suparmo Suparmo; Wahyu Supartomo; Zaki Utama

A model fruit product was prepared using fresh tropical fruits puree (jackfruit and sapodilla) and restructured using calcium-alginate gel forming methods (internal setting). Restructured fruit products were evaluated for texture (hardness), color, pH, and sensory properties after 0,1,2, and 3 months frozen storage at -15ºC. No significant change for pH was observed over the frozen storage period (3 months at -15ºC).

This research aimed to investigate the influence of three types of palm oil products (RBDPO (refined bleached deodorized palm oi), RPO (red palm oil), and PKO (palm kernel oil)), on serum glucose and lipid profile of Sprague Dawley rats fed with experimental diet containing 20% of oils, comparing these effects with those of with animal- base oil (beef tallow) including corn oil as a representative from vegetable oil. The diet with level of fat 20% given to two groups (with and without AOM (azoxymethane)) of male Sprague Dawley rats for 13 weeks. The results exhibit that corn oil caused the lowest value of serum glucose (p < 0.05) in both AOM and non-AOM groups. Compared to other groups, beef tallow diet significantly increased serum triglycerides, cholesterol, and LDL, followed by RPO/PKO, RBDPO, and corn oil, respectively (p < 0.05). Meanwhile, corn oil diet produced the highest level of serum HDL, followed by RBDPO, PKO/RPO, and beef tallow (p < 0.05).
