CHARACTERISTICS OF AMYLUM, AMYLOGRAPH, AND SWELLING POWER OF YELLOW PUMPKIN FLOUR WITH DIFFERENT FERMENTATION TIMES
Yellow pumpkin flour has disadvantages, including reduced fluffiness and a strong water-binding capacity.This study aimed to analyze the effects of fermentation duration on the amylum characteristics, amylograph properties, and swelling power of yellow pumpkin flour to determine the optimal fermentation time.A randomized experimental design with one factor-fermentation duration-was used, consisting of six treatments (0 to 5 days of fermentation), with each treatment repeated four times.The parameters measured included amylum, amylose, amylopectin, amylograph, swelling power, pH, solubility, and moisture content.The results indicated that fermentation time significantly affected most parameters except gelatinization time.Extended fermentation improved amylograph properties by enhancing gelatinization and retrogradation, although paste stability during heating decreased.However, prolonged fermentation did not enhance the flour's ability to expand, but it did increase water-binding capacity.The study concluded that one-day fermentation was optimal, as it improved gelatinization, retrogradation, and solubility while maintaining a high swelling power in yellow pumpkin flour.This fermentation period produced flour with improved functional properties, making it more suitable for various food applications.Future research should explore further modifications to enhance expansion properties while maintaining the benefits of fermentation on yellow pumpkin flour's quality.

Chemically modified starches are widely used as food additives to improve the appearance and physicochemical and biological properties of foods. The aim of this work is to chemically modify chayotextle (Sechium edule) starch by hydroxypropylation‐crosslinking, and evaluate the effects of degree of substitution (DS), swelling power (SP), solubility index (SI), pasting, thermal properties, and morphological and molecular characteristics. Polar‐Tex (modified maize starch) is used as control. The modified chayotextle starches (CHSs) exhibit a white color and DS values between 0.34% and 1.19% hydroxypropyl, dependening on propylene oxide concentration‐response. In addition, the SP and pasting properties are higher in modified CHS than in native CHS and Polar‐Tex. The SI and temperature of gelatinization of modified starches decrease compared to native sample. The morphology of native and modified CHS granules is spherical and oval. Fourier transform infrared and nuclear magnetic resonance studies confirm the structural modifications of CHS by hydroxypropylation‐crosslinking. Dual‐modified CHS can be potentially used as an additive in the food industry.

Chestnut is one of China's traditional export commodities in the international market and enjoys a positive reputation. Its key quality attributes are closely linked to changes in the physicochemical properties of chestnut starch after thermal processing. This study investigated the effects of different temperatures (100 °C, 160 °C, and 200 °C) and times (10, 20, and 30 min) of dry heat treatment (DHT) on the physicochemical and structural properties, as well as the functional properties of chestnut starch. The results demonstrated that DHT increased the solubility (S) and water absorption capacity (WAC), but reduced the swelling power (SP), transmittance, and gelatinization characteristics. DHT modified the starch's functional properties, increasing its digestibility. This was reflected in the rise in rapidly digestible starch (RDS) and the decline in resistant starch (RS) content. Scanning electron microscopy (SEM) revealed that cracks, crevices, and pores appeared on the starch granule surfaces after DHT. X-ray diffraction (XRD) analyses revealed that the relative crystallinity (RC) of starch decreased with higher temperatures and longer treatment times. The ability of DHT to alter the physicochemical and functional properties of starch provides foundational data for the possible modification of chestnut starch and its application in starch-based food products.

Locally grown crops with phytochemical antioxidant content i.e. goroho plantain and yellow pumpkin were used to develop composite flour. Mixture experiment with simplex lattice design was used for formulation to study the effect of blending goroho plantain flour (GF) with yellow pumpkin flour (PF) on phytochemical content and antioxidant capacity of developed composite flours. Responses measured including phytochemical content (total phenolic and carotenoid), antioxidant capacity (DPPH assay, FRAP assay, phosphomolybdenum assay, and reducing power assay), colour values of flours, proximate components, and sensory quality of biscuits made from composite flours. The results showed that increase in proportion of PF improved the phytochemical content, antioxidant capacity, and proximate components with the exception of carbohydrates. However, substitution of GF with PF reduced sensory ratings for all the sensory attributes of biscuits developed from composite flours. Among biscuits made from composite flours, sensory ratings for aroma, colour, texture, and taste were not statistically different (p>0.05). PF can be used as fortification material to improve the phytochemical antioxidant content in composite flours prepared from GF and PF, or flours from other locally grown plants.

Diabetes Mellitus (DM) is a global epidemic with high morbidity and mortality. Diabetes Mellitus (DM) is thought to have a negative impact on sperm quality. Yellow pumpkin contains antioxidants that can neutralize free radicals which can improve fertility. Glucomannan is a substance contained in porang which functions as a soluble fiber and plays a role in blood glucose balance. This study aims to examine pumpkin flour, porang flour and a combination of both flours on sperm motility and body weight of alloxan-induced diabetic mice. This study used 25 mice aged 3 months, body weight 25gr-30 gr. This study used a completely randomized plan (CRD) with 5 replications and 5 treatments. The treatments were negative control (diabetic mice), positive control (administration of glimepiride at a dose of 0.0078 mg/mice per day), D1 (pumpkin flour 134.4 mg/30g BW of mice), D2 (porang flour 63mg/30g BW mice), D3 (combination 50% : 50% = 67.2 mg : 31.5 mg/30 grBW mice). Diabetic mice were made by intraperitoneal induction of alloxan dose of 200 mg/Kg for 3 days. The parameters observed were spermatozoa motility, body weight and blood sugar levels of the mice. The research data were analyzed using the ANOVA test followed by the BNT test. The results showed that the administration of glymeride, pumpkin flour, porang flour and their combination had a significant effect on reducing blood sugar (p=0.000) and sperm motility (p=0.000), but had no effect on body weight (p=0.317). Conclusion: pumpkin flour, porang flour or a combination of both flours can be used as herbs to lower blood sugar and increase sperm motility in diabetes sufferers.

Puff Pastry is a type of pastry from France made from a mixture of wheat flour, pastry margarine, and water. In this innovation, pumpkin is added to reduce the use of wheat flour by utilizing the availability of pumpkin as a local and functional food. The production process of puff pastry is divided into three stages: making pumpkin puree, making puff pastry, and packaging. The processing of puff pastry with pumpkin substitution is done by adding pumpkin in the form of flour and puree, which provides a new flavor and increases the betacarotene content. The experimental design consists of 6 samples, F1: 5% pumpkin flour, 95% wheat flour; F2: 10% pumpkin flour, 90% wheat flour; F3: 15% pumpkin flour, 85% wheat flour; F4: 40% pumpkin puree, 60% wheat flour; F5: 50% pumpkin puree, 50% wheat flour; and F6: 60% pumpkin puree, 40% wheat flour. A sensory test was conducted to determine consumer preferences and acceptance. The selected sample in the sensory test was puff pastry with 60% pumpkin puree (F6). To determine the final product characteristics, water content tests were performed with three repetitions, as well as a betacarotene content test (315.70 µg/g). Based on the economic analysis, including calculations of HPP (Cost of Goods Sold), BEP (Break-Even Point), ROI (Return on Investment), POT (Payback Period), NPV (Net Present Value), and B/C ratio, the pumpkin-substituted puff pastry production business is profitable and feasible to run.
